Module 9 Great inventions 阅读理解 专练（含解析）外研版版英语九年级上册
Imagine wearing a magic hat that allows you to write words down just by thinking of them. This is not a sci-fi story, but actual research done by students at Tianjin University. They used brain-computer interface(接口)(BCI) technology to write the character “fu (福)”. “It’s ‘written’ by a robotic arm controlled by our researchers’ minds,” said Xu Minpeng, a professor at the university.
In the lab, two researchers wear caps with sensors (传感器) while their eyes focus on a computer screen to “mind write” the character. After a computer reads signals from their brainwaves, a robot writes the character on red paper. It takes 3 minutes for the researchers to write “fu”.
In fact, BCI technology has already been used in several different areas. In 2016, Chinese astronauts Jing Haipeng and Chen Dong used it in the Tiangong II space lab. They tested a BCI system in space for the first time. It is hoped that in the future, astronauts can use these systems to do difficult tasks, since it’s not easy for them to move around in space.
BCI technology can also help people with disabilities. For example, people who have lost their hands or arms can use BCIs to write messages and surf the Internet. BCIs could also be used in smart homes in the future. Simply thinking “turn on the light” could turn on the lights in your home.
Elon Musk, founder of Space X, is also working on BCI technology. Last year, Musk’s researchers implanted a chip into the head of a pig. The chip collects signals from the brain and sends them to nearby computers wirelessly (无线地). Musk hopes that in the future, humans can use these chips to control things with their minds.

Have you ever wanted to see your dreams after you woke up AI technology may help you do this in the near future!
Researchers from Osakn University in Japan have trained an AI system to recreate images(重现图片) in people’s heads. The pictures AI has created include a teddy bear, an airplane and a clock tower. The technology is 80 percent accurate(准确的), reported Science magazine.
Previously(之前) there have been AI models that can turn a word or phrase into images. The AI has studied lots of images and their text descriptions. Over time, the AI can find patterns and recreate pictures if you first input(输入)text.
This time, the researchers took a step further. They trained the AI to link people’s brain scan data(扫描数据) with images. Then the AI find patterns of blood flow in the brain. Next, it would turn on the previous “text-to-image” model to improve the text. Finally, the AI would turn the text into the image.
“It’s a new method that combines(结合) textual and visual(视觉的) information to decipher(破译) the brain.” an expert from Princeton University told Science magazine.
Researchers said the technology could someday help people with paralysis(麻痹) to communicate. It might also help scientists understand dreams or even how other animals see the world.
5．What do we know about the AI system mentioned in Paragraph 2
A．It can help train people’s minds. B．It was created for drawing people’s heads.
C．It can recreate pictures in people’s heads. D．It can fully present people’s dreams.
6．How did the previous AI models turn phrases into images
A．By drawing pictures according to users orders.
B．By understanding the meaning of the words.
C．By finding different photos from the internet.
D．By finding patterns in images and their text descriptions.
7．What is the working process of the new AI system
A．relate with image→scan blood flow→improve the text→turn into the image
B．relate with image→turn into text→scan blood flow→improve the image
C．scan blood flow→relate with image→turn into text→improve the image
D．scan blood flow→turn into text→relate with image→improve the image
8．What is the last paragraph mainly about
A．How to know the way animals see the world. B．How people with paralysis talk with others.
C．What the new AI technology could be used for. D．How AI technology affects people’s dreams.
Every minute, someone is setting up an Internet company somewhere, in the world. Each one is searching for the one great idea that could make his web company click in a big way. And they are trying all kinds of tricks to attract people towards their websites. While some websites offer sounds, cartoons and amazing photos on screen to make their sites almost a movie-like experience for the viewers, others provide free downloads and competition.
A company in California, US, has decided to offer online smells to people who visit its website. That is, if a pizza image comes on screen, your nose will catch the smell of bread and cheese! All you need to do is to connect a device (设备) called “iSmell” to your computer. This smart little device contains some chemicals that can create different kinds of smells.
The company has invented software that changes the chemical composition (成分) of different smells into digital signals. An onscreen image, which is programmed with the proper digital signal, will start the “iSmell” device. The device will use the software to change the digital signal again and let go of the correct smell. This device reads the digital smell code (代码) from the website and creates the proper smell from its store of chemicals. This smell is then made to blow softly in the direction of the user with the support of a small fan.
In order to let go of the correct smell, the company has created a “Scent Registry”, which contains a digital index (索引) of thousands of smells. The company plans to allow website developers to integrate the proper smells in digital code to their games and images. The company is also hoping that Hollywood filmmakers will use the smell technology in their movies. Imagine audiences getting the smell of rocket fuel as a spacecraft takes off on the cinema screen! Of course, filmmakers will have to be careful not to shoot in dirty neighborhoods, which have a lot of rubbish lying around.

Since the COVID-19 outbreak, many people have been forced to stay at home for long periods of time to protect themselves from the virus. This has given people more free time to learn new skills and find different ways to entertain themselves.
Some of these activities include things like singing, learning to cook and ordering fresh food online. All of these things can be done in the palm of your hand with mobile apps.
Before, young people would go outside and meet friends at karaoke bars. Now, friends can meet and sing on the mobile karaoke app Changba, which translates to Singing Bar. “The Changba app not only gives me the chance to sing whatever I like at home, but also lets me keep in touch with friends by sharing our songs,” said an app user.
Some people have also taken up cooking as a new hobby to pass the time. You don’t need to attend culinary(烹饪的) school, thanks to apps like Xiachufang and Ecook, which make it easier for those who want to learn how to cook. These apps provide a platform for users to look up different recipes (菜谱) and to share their own recipes with others. “Using this app, I have learned many new and healthy dishes which help me eat better,” an app user commented on the app’s website.
To help people avoid crowded places like grocery stores, apps that deliver goods right to your door have also become very popular. “It is noteworthy that the epidemic has attracted new groups of consumers(消费者), such as elderly people, who originally didn’t belong to our target user group,” Zhang Yi, an analyst (分析师) from the market research company iiMedia Research, said.
Indeed, during this special time, these apps have opened up a whole new world of opportunities for people of all ages and backgrounds.

What is 5G
The “G” in “5G” refers to the generations of mobile network technologies. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and the Internet, and 4G made all of these things faster.
Now 5G promises much faster data download and upload speeds, and more stable connections. For example, when you have a video chat with your friend, there is generally a 100 to 200 milliseconds delay with 4G, but 5G will reduce the delay to 1 millisecond(毫秒) or less.
What changes will 5G bring us
According to the Straits Times, 5G will be able to improve many advanced technologies, such as driverless cars, wearable devices and entertainment.
Does 5G have any disadvantages
According to the BBC, though 5G will make our lives more convenient, it will not be perfect.
For one thing, 5G will not “travel” far. On 4G networks, you can be 10 kilometers away from the nearest transmission base and barely lose signal. But 5G will only cover about 300 meters, meaning that we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new products specifically designed for 5G that are currently expensive.
17．According to the passage, what can 3G do
A．People can send messages. B．People can talk to each other.

Artificial intelligence (AI) (人工智能) is the ability of a computer program or a machine to think and learn. It is also a field of study that tries to make computers "smart". John McCarthy, a scientist, came up with the name "artificial intelligence" in 1955. Many things such as learning and problem solving can be done by computers, though not in the same way as we do.
An unusual goal of AI research is to create computer programs that can learn, solve problems, and think logically. At present we use the term AI for successfully understanding human speech, recognizing (识别) human faces, operating self-driving cars and competing in some game systems like Chess and AlphGo (阿尔法狗). Some people also consider AI a danger to humans if it develops too quickly. Professor Stephen Hawking, a well-known British scientist, was not for this kind of technology.
Math is the basic language of AI. If we raise the standard in the learning of math, our students will be more likely to become successful AI designers in the future. We not only want bright students, but also need to attract average students and give them the math skills which are needed to change them into AI designers. Besides, a good knowledge of computer science is also necessary for AI designing.
Scientists hope to create creative and emotional AI which can possibly understand human feelings or create art. Many ways and tools have been tried to discover this fascinating field.
26．From Paragraph 1, we know that ___________.
A．all problems can be solved by AI

What do you use to unlock your cellphone A password A fingerprint Or simply a glance（一瞥）
On September 12, 2017, Apple introduced its iPhone X, which has an eye﹣catching feature（特色）﹣Face ID．
With Face ID, Apple says, you can unlock your new iPhone by just looking at it. It is powered by a so﹣called True Depth camera system built into the front of the iPhone X.
When the camera system sees a person's face, it uses 30, 000 unseen dots（点）to "map"（勾画）the shape and outline of the face. A mathematical model of the face will then be created and stored（储存）in the phone.
The next time the person looks at the iPhone X, the same dots are mapped onto his or her face and compared to the stored model. If the two match, then the phone unlocks.
This happens in less than a second.
Apple says the system is smart. If you change your hairstyle, put on sunglasses or makeup, or use the phone in the dark, Face ID still works.
Although the technology sounds fancy, there are still concerns（担心）. For example, will Face ID work for twins
According to Apple, the chance of others to unlock your iPhone X using Face ID is one in a million. Face ID can tell the difference between twins, but the error rating（出错率） rises. So one would need to set a password then.
Apple also emphasizes（强调）that Face ID only unlocks when you stare at it. It is what Apple calls "attention aware（察觉）". So the phone won't unlock if you are just glancing at the phone for the time. It won't work either if someone puts the phone at your sleeping face or your photo.
41．The new function（功能） of the iPhone X is that you can unlock it with ________.
A．a sign B．a password C．a fingerprint D．Face ID．
42．The camera system of Face ID works by ________.
A．remembering users' faces by taking their pictures
B．using a map to store face models of its users for later use
C．matching the users' faces with unseen dots stored in the system
D．creating a face model of the user and comparing it with the user's face later
43．Face ID doesn't work when you ________.
A．wear a mask B．put on sunglasses
C．change your hairstyle D．use the iPhone X in the dark
44．You would need to set a password to prevent________ to unlock your iPhone X with Face ID．
A．your parents B．your classmates
C．your twin brother D．your best friend
45．The main idea of the passage is that________.
A．the iPhone X can't recognize a person's face
B．Face ID is a program to unlock the iPhone X
C．people worry about the safety of using Face ID
D．we can unlock the iPhone X in three different ways
Consumer electronics (消费性电子品) once again topped the list of the most wanted gifts this holiday season.
“Seventy-six percent of consumers who plan to buy holiday gifts say that they will spend money or buy at least one technology product; definitely a solid vote of confidence for technology.”
Steve Koenig is with the Consumer Electronics Association. He says the group’s latest research also shows that Americans this year are spending more on technology products. Here in 2012, $252 on average—the technology spend for consumers this year.
From tablet computers to smart phones, American shoppers have been lining up to get the newest and coolest electronic devices on the market. There are more choices today than ever before. It’s kind of hard to make a decision.
Tablet computers are one of the best-selling products this year. Brian Tong is Senior Editor of . The website reports on tech news and examines the latest electronic products. He says the Apple iPad Mini is one of the most popular tablets. Its starting price is $329. One of Apple’s biggest competitors is the Google Nexus 7. It starts at $199.
“Its hardware is more powerful than what’s in the iPad Mini, but also it offers you a lot of things like maps that work better than Apple’s maps.
But Brian Tong says there is one reason why people may like the iPad Mini more than the Nexus 7. “If you just want to read books and surf the Internet, you don’t really need to get an iPad Mini, but if you want the largest robust group of apps that’s where the iPad and Apple’s ecosystem shines the most.”
Elman Chacon is with the electronics store Best Buy. He says another hot product this season is smart cameras. They connect to the Internet through WiFi. This makes it easy for users to email or upload photographs directly from the camera.
“You can literally take a picture and upload it into your Facebook in a matter of seconds. These things are pretty cool because they do a lot of things.”
Streaming media boxes also connect to the Internet. People are able to watch web content such as movies and YouTube videos on their televisions. Another popular item is wireless speaker systems. The newest ones work with any device that has Bluetooth technology, including smart phones, laptops and tablets.
46．According to Brian Tong, why may people prefer the iPad Mini to the Google Nexus 7

Have you ever paid for educational podcasts (播客) or live videos Ask some people and most of them will say yes. “Pay-for-knowledge” has been a fashionable thing these years. Everything you think of can be found online, skills of talking, designing, computer programming — you name it!
Why is “pay-for-knowledge” industry (产业) developing so rapidly First, its development is based on the Internet. With a fast network and a smart phone, anyone who has passed the identity (身份) check can be an online teacher, and anyone with an online account can buy “pay-for-knowledge” products that he or she wants at a good price. Second, people are afraid to miss any information. They hope for more useful information which is usually at the hands of experts. Moreover, the need to learn new skills in today’s job market also pushes people to learn on such educational podcasts.
The industry of “pay-for-knowledge” has proved to be a great way of making money. It promises possibilities of turning information into money. It is good for the development of our country and it can help sellers make lots of money. Besides, buyers can enjoy self-growth from it. What’s more, this is a reflection (反映) of people’s respect for knowledge and talents.
However, “pay-for-knowledge” also causes a few problems. For one thing, the market is full of eye-catching words such as “How to be an Industry’s Expert ” which sounds like if you pay for it, you are sure to succeed. For another, a large number of customers buy them just for showing off. That means, with or without these products, they can make it anyway, because they are those who have the ability to learn by themselves.
In general, the best is the one that suits you most. “Pay-for-knowledge” may be used as a good start for self-growth. But be careful when you make a choice, or your dream of success may not come true.
54．“Pay-for-knowledge” industry is developing rapidly because of the following reasons EXCEPT ____.
A．people today don’t want to miss information
B．the traditional education system doesn’t work
C．today’s job market need people to be more skilled

Whether from news reports or social media articles, you may know that 5G is coming.
5G is the 5th generation network. It is a new network(网络)after 1G, 2G, 3G and 4G and it can connect everyone and everything together. 5G networks will cover many cities in China soon. 5G means super-fast data(数据) speed, one can download a two-hour movie for fewer than 10 seconds, and it is making our lives more and more convenient.
5G will make self-driving cars possible. For safety, self-driving cars need super-fast data transmission(传输)to communicate with their nearby environment. 5G is just what makes self-driving cars achieve this. Eyen airplanes will become "smart" in the near future. Passengers will be able to use 5G networks in the air to connect to the Internet or place orders for food and drinks.
5G will be a big help for students who take online classes. Many people live in poor areas in the world where there are no schools. But with 5G, this will change. Students all over the world will be able to see places like the Great Wall without leaving their rooms.
It will be also easier for doctors to treat patients remotely by 5G. It means caring for patients from far away.
The facts listed above are only a part of what 5G will make possible and popular. Just as in the early days of the Internet in the 1990s, few could see how it could change the world. The same will surely be true of 5G. With 5G, many things do not seem like dreams anymore. Now let's get ready to say goodbye to 4G and welcome the coming of 5G.

Dogs have an amazing talent for understand human social behavior, and they can take actions upon human orders, but what if they are given instructions not by real humans but by humanoid robots that behave like humans Will dogs obey the robot's orders
At the International Conference on Human Robot Interaction2020. Researchers at Yale University’s Social Robotics Lab tested how dogs responded to instructions from robots. A group of 34 dogs participated in the experiment, and each dog was tested with either a speaker or a human-like robot in a room. After a brief introduction to the testing environment, the robot or speaker called the dog's name, using the same voice. Then the robot or speaker would give a "sit" order, which was the real test.
Results of the experiments showed that the dogs paid more attention to the robot than the speaker. Dogs obeyed the "sit" order over 60% of the time when it came from the robot, but less than 20% of the time when it came from the speaker, even if they did look a bit confused about the whole thing at times.
While these results are certainly interesting, it's important to answer the question of whether dogs could respond to a social robot at all. The researchers were giving the dogs a great opportunity. For example, the dogs' owners were instructed to interact with the robot, talking to it and making eye contact, to help encourage the dogs to see the robot as friendly and make the anxiety less while also drawing attention to the robot. However, they haven' t discovered what factors (因素) might increase or decrease that likelihood.
"Since dogs are very sensitive to human social cues (暗示), the robot being humanoid or not may make a difference, lead researcher Meiying Qin said. "Yet, if a non-humanoid robot behaves like a dog or shows any social behaviors, dogs may also respond in a social manner."
"Now that we have evidence that dogs do respond to social robots, the next step is to figure out what we haven't discovered yet," added Meiying Qin. "Humanoid robot, which is one of the greatest invention in the 20th century, is the advanced representation of robot technique." Some people may question the value of making social robots for pets. Dogs aren't the only animals that robots interact with, of course the larger idea is that by studying how dogs behave toward social robots relative to humans, it can help us understand bow social robots affect our own behavior, too.
63．Paragraph 2 is mainly about ________.
A．how the test was performed B．what was found in the test
C．why the scientists did the test D．who took part in the test
64．The researcher later will probably focus on ________.

A．dogs seldom obey the order from a humanoid robot
B．dogs pay less attention to a mechanical-looking robot
C．dogs can pay more attention to owners’ voice in the speaker
D．dogs can understand the social meanings from machines
66．The lead researcher Meiying Qin probably agrees that ________.
A．humanoid robots can influence humans’ behaviors
B．it is worthless to design advanced robots for animals
C．robots will take the place of humans to look after pets

Data in the cloud is always stored in an encrypted form in cloud storage services so that it can’t be let out. The business cloud storage systems use a specific encryption key. The key can be stored either by the service itself or by individual users. Most services keep the key themselves, allowing their systems to read and perform operations on the data. It’s much more convenient than having users keep the key themselves. But it’s also less secure. Data might not be safe if the keys are stolen.
Some less popular cloud services, including Mega and Spide Oak, requires users to upload and download files through applications that have encryption functions. This extra step lets users keep the encryption keys themselves, yet users will fail to use some functions, such as searching among their cloud stored files.
Therefore, these services aren’t flawless. There’s still a possibility that the apps might be broken in and the files can be let out. What’s more, if a user loses the password, the data will never be found back.
, it’s best to combine the features of these different ways. Before uploading data to the cloud, first encrypt it with your own encryption software. Then, upload the encrypted file to the cloud. To get the file again, download it and then decrypt it.
This, of course, prevents people from using many cloud services. And the company providing the cloud services could still do with the data before you download it.
So the best way to protect against that is to use authenticated encryption. This method not only stores the data, but also allows a user notice whether the file has been changed.
Finally, for those who don’t want to learn how to programme their own tools, here are two basic choices: Find a good cloud storage service or use a good enough encryption software. These are generally free or very low-cost.
72．What does the underlined word “flawless” probably mean
A．perfect B．valuable C．important D．convenient
73．Which sentence can be put in the blank in Paragraph 4
A．To provide plenty of new data B．To get the information easily
C．To protect the files in the cloud D．To find some searching functions
74．According to the passage, how do cloud services keep data safer
A．Only the users can own the encryption key of the data.
B．The cloud services keep the encryption key for the users.
C．The users use authenticated encryption when storing the data.
D．The users upload and download the data in Mega and Spide Oak.
75．What can be the best title for the passage
A．What is Data Security B．What is Encryption Key
C．How to Get your Data Easily D．How to keep your Data Safe
China is running ahead in 5G . In March, 2019, the Shanghai Hongqiao Railway Station became world's first "5G railway station". Now, it takes only 20 seconds to download a long movie there.
We are moving closer and closer to the 5G world. However, the new technology is still strange to most of us. What is 5G, after all At first, 5G is fast. 5G will be much faster than today's 4G networks!
The first 5G modem（猫，调制解调器）of the IT company Qualcomm supports speeds of up to 5 Gigabytes（千兆字节）per second. Most of us have never experienced anything close to that speed. And we are only talking about the first generation（一代）of 5G modems, Future models are likely to be even faster.
But 5G is not all about speed. Have you ever been to a large event where your data (数据)connection slowed down That is because 4G networks can only support a certain number of devices(设置) per square meter. 5G networks will be able to do much better. They can support up to a million devices(设置) per square kilometer.
Now, you begin to understand why 5G is a huge change over 4G. The technology is not Just for the smartphones. It has a strong influence(影响) on every connected device. With 5G, self-driving cars will be able to communicate with the world around them as quickly as possible. Wearables, Pcs and smart home devices will be able to improve as well.
Are you looking forward to that 5G world now

China has made efforts to ensure data security(保证数据安全) in facial recognition(人脸识别) as the technology has raised increasing worry over users’ personal information leakage (泄露) while being more and more widely used in Chinese people’s life and work, including unlocking mobile phones, verifying identity(身份验证) , and clocking in.
Recently, some people complained that some estate(地产) businesses installed(安装) cameras that support facial recognition at their sales offices to secretly take photos and store the facial features of buyers without permission.
According to a survey report, more than 90 percent of the respondents(受访者) have used facial recognition systems, and over 60 percent of them believe that the technology seems to become overused and often faces problems such as forced use and illegal collection of users’ information.
Experts pointed out that some people are against facial recognition because in the era of the Internet, they think it more important to protect their personal data, and unlike other body information, facial features can be more easily collected before people realize it.
Besides, unlike other personal data that can be easily changed, such as user name, mobile phone number and e-mail address, facial information is unique and can’t be changed. Once their face data is collected by companies, there’s no way people can know if these companies will keep it safe and prevent illegal(非法的) use of the data, explained experts.
Therefore, it is important to use facial recognition systems properly and store safely people’s face data with their permission.
In fact, facial recognition has played a positive role in fields like public service. During the prevention and control of the COVID-19 epidemic, contactless facial recognition devices, which can accurately and efficiently identify people’s faces and take their temperature, have been widely used in shopping malls, restaurants and office buildings, actively contributing to the fight of the virus.
With the development of facial recognition technology, some devices can effectively identify people even with their facial masks on. In a huge face database with 300,000 images, such devices can have an accuracy rate (准确率) of as much as 90 percent in identifying people with their masks on, suggested a research report by many companies and organizations in December 2020.
Obviously, it is unwise to neglect (忽略) the advantages of facial recognition and simply give up the technology.
To ensure data security, the National People’s Congress of China issued(发布) a draft law on personal information protection in October 2020, formulating provisions(制定条文) on the installation of facial recognition equipments in public places.
①
Experts believe that as the improvement of the laws, the application(应用) of facial recognition technology is expected to be brought under good control, and continue to play an active role if people’s personal data are kept safe.
81．Which column (栏目) of the newspaper is this article from
A．Art and literature. B．Language and culture.
C．Travel and business. D．Science and technology.
82．Which of the following is TRUE according to the article
A．Some estate businesses installed cameras without permission.
B．Almost all the respondents believe the technology overused.
C．Facial information can be easily collected but can’t be changed.
D．Contactless facial recognition devices helped a lot all the time.
83．The missing part ① probably tells us something about ________.
A．some examples about protecting our personal information
B．some details about the law on personal information protection
C．how to install facial recognition equipments in public places
D．when and where we can install facial recognition equipments
84．What’s the writer’s attitude (态度) about facial recognition technology
A．He is afraid that it will not be controlled. B．He is sure that it only has advantages.
C．He suggests that we had better not use it. D．He believes it can play an important role.
