Giant bumper car Dan Hryhorcoff from Pennsylvania, US, built a bumper car legal (合法的) for the road. The car is about 4 metres long, twice the size of a children’s bumper car. The car has a motorcycle wheel at the front. The single wheel means it can turn very sharply. Making the car has brought Hryhorcoff a lot of joy. When this blue bumper car hits the road, it will make everyone laugh.
________________________________ Check out this Wind Tree! It looks like a tree with 36 green “leaves”, but it’s a small wind turbine (涡轮机). It’s about 5 to 10 metres tall and easy to build. Each “leaf” can turn with the wind and create electricity. It can make 18,000 kilowatt-hours of energy in a year. That’s enough to power a house of four people.
Driving through to charge (充电) cars Drivers usually need to wait for a long time for their electric cars to charge. Now, a road in the US can charge electric cars as they drive along the road or park on it. There are charging coils (线圈) under the road, and the cars have special receivers. When the car comes near, the coils send electricity through a magnetic field (磁场). It’s safe for people and animals to walk on the roads.

Alexis Lewis is a girl from America. She likes to invent — to think of new ideas for things that no one has made before, and then make them.
Alexis often enters competitions for young inventors. When she was younger, she spent time with her grandfather, who made transport (运输工具) for people to go to space. One day Alexis’ mother told her about a newspaper article which explained how difficult it was to get sick people through the countryside to hospital in Africa. Alexis wanted to help.
Alexis knew that in North America, before there were cars, horses pulled heavy things on a travois (旧式雪橇), made of wood. Alexis thought people could do the same, but she added wheels. To make her travois light, she used bamboo, a plant that grows in Africa, not wood.
To pull Alexis’ travois, you wear a belt (腰带), which means you can carry or hold other things.
Alexis thought her travels was ideal for carrying food home from the market, as well as taking people to hospital. After it was finished, she wrote instructions for building one s ______ could make it themselves.
With help from US companies, Alexis gave some free travois to hospitals in Africa. She didn’t ask them for money because they were for poor people.
Alexis doesn’t know if she wants to be an inventor when she’s older, because she also likes music and writing, but she thinks it’s important for children to learn about inventing at school.

For the first time, scientists have grown plants in moon soil collected by NASA’s Apollo astronauts.
The scientists had no idea if anything would grow in moon soil. They wanted to see if it could be used to grow plants. Robert Ferl of the University of Florida was surprised with the results. “Plants actually grow in moon soil,” he said.
Ferl and other researchers planted thale cress, a small flowering plant, in moon soil. The good news was that all of the seeds grew. The bad news was that after the first week, they grew slowly. Most of the plants ended up small and not fully developed.
Scientists found that the longer the soil was on the moon, the worse the plants seemed to grow. The soil collected by the Apollo 11 was the least helpful for growth. ___★___. One solution might be to use younger soil on the moon, like lava (火山岩浆), or put in some special nutrient (营养物) mixtures.
Only 382 kilograms of moon rocks and soil were brought back by the six Apollo groups that landed on the moon. Early last year, NASA finally gave out 12 grams of soil for the planting experiment (实验).
The Florida scientists hope to reuse their moon soil later this year, planting more thale cress before possibly moving on to other plants.
A scientist said, “Growing plants is a big step forward. The real next step is to go and do it on the surface of the moon.”
( )26. What did Robert Ferl think of the results of the planting experiment
A. Surprising. B. Disappointing. C. Awful. D. Regretful.
( )27. Which of the following can be put in __★____
It was fully used by researchers
It weighed less than 283 kilograms
It was the newest soil on the moon
D. It was a couple billion years longer
( )28. What do the Florida scientists plan to do this year
A. To find some younger soil on the moon.
B. To make some special nutrient mixtures.
C. To plant some other plants in new moon soil.
D. To use the moon soil again in the experiment.
( )29. What may be the real purpose of the planting experiment
A. To collect more soil from the moon.
B. To send more scientists to the moon.
C. To grow plants on the moon’s surface.
D. To plant more thale cress on the moon.
( )30. What can we infer from the passage
A. Most of the plants grew well after two weeks.
B. The soil collected by the Apollo 11 is the oldest.
C. It is easy for astronauts to bring back moon soil.
D. Scientists found no ways to improve the experiment.
