How do you deal with plastic bags from the supermarket Throw them away or recycle them How about eating them
The bags are not harmful to the environment. Humans and animals can safely eat them. An Indian company EnviGreen has made a bag with natural materials. It looks and feels just like plastic, but it can be broken down(分解) easily.
Ashwath Hedge who set up EnviGreen spent four years doing experiments with 12 natural materials. They included potatoes, corn, vegetable oil and bananas. He made the materials into liquid(液体) and used the liquid to make the bag.
Although the EnviGreen bag is more expensive than a common plastic bag, it has many advantages. According to The Wall Street Journal, it takes 1,000 years for common plastic bags to be broken down. But an EnviGreen bag can naturally be broken down in less than 180 days. It is also broken down in less than a day in water, and in less than a minute in boiling water. Hedge was happy to show it in his interview. He put an EnviGreen bag in water and ate it with a smile.
There are more than 15,000 tons of plastic waste in India every day. But only 9,000 tons are processed(处理). In China, 3 billion plastic bags are used every day. Maybe the EnviGreen bag could be a solution to the world problem of plastic pollution.

四、任务型阅读
Answer the questions (根据短文内容回答下列问题）
It was a village in India. The people were poor. However, they were not unhappy. After all, their forefathers had lived in the same way for centuries.
Then one day, some visitors from the city arrived. They told the villagers there were some people elsewhere who liked to eat frog’s legs. However, they didn’t have enough frogs of their own, and so they wanted to buy frogs from other places.
This seemed like money for nothing. There were millions of frogs in the fields around, and they were no use to the villagers. All they had to do was to catch them. Agreement was reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. For the first time, the people were able to dream of a better future. But the dream didn’t last long.
The change was hardly noticed at first, but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often, and, there seemed to be more insects around lately.
The villagers decided that they couldn’t just wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides and medicines. Soon there was no money left.
Then the people realized what was happening. It was the frog. They are not useless. They do an important job—eating insects. Now with so many frogs killed, the insects were increasing more quickly. They were damaging the crops and spreading diseases.
Now, the people are still poor. But in the evenings they sit in the village square and listen to sounds of insects and frogs. These sounds of the night now have a much deeper meaning.
28．Did the villagers live a different life from their forefathers
29．Who wanted to buy frogs
30．Why did the villagers agree to sell frogs
31．What do frogs do in the fields
32．What might be the cause of the children’s sickness
33．What lesson can people draw from the story

April 22 is World Earth Day—a day to remind people to protect our planet. On that day, my family and I took the “bottle of garbage challenge”. We challenged ourselves to produce as little garbage as possible in 24 hours. The garbage needed to fit inside of a 700-milliliter bottle.
I was highly alert (警觉的) that day. I thought about what waste every action would produce. When I solved math problems on paper, I tried to use every blank space. I also reused a straw (吸管) and napkins (纸巾). In the end, I put all my trash in a 600ml bottle. There were apple cores, eraser crumbs (碎屑) and other things.
Grandma needed to cook supper, so she had plenty of kitchen waste. When she cooked, she picked off leaves. There were also eggshells and food packages. And of course, there were leftovers (剩饭) after dinner. But she asked us to eat most of the dishes and waste as little food as possible! Although Grandma produced lots of trash, she was able to fit it all into a 700ml bottle!
My father and mother worked online. They sent and received emails. So they didn’t produce any paper waste and made the least trash in my family.
I’ve benefited a lot from this activity. I realized that everyone can make lots of trash every day. In the long run, it will become a great burden (负担) to our mother Earth. We should start with small actions to protect it.

Have you ever heard of e-waste, which can be produced every day How do you deal with your computers, CD players and mobile phones when they’re broken or you want a new one Most people just throw them away.

It’s important to pay attention to e-waste. It can either be valuable or harmful, depending on how we deal with it. E-waste is a valuable urban mine (城市矿藏). The value of the metals, like gold and silver in the waste around the world, is amazing. And the metals can be reused. But if people throw them away, the toxic chemicals (有毒化学物质) can get into the earth or air. They will do harm to environment and affect people’s health.
To help reduce (减少) e-waste, we can buy longer lasting e-products. If you have unwanted e-products, find a new home for them. You can also take computers and phones to see if companies offer recycling programs. For example, Xiaomi company now recycles people’s used products in China when they are buying new ones.

This makes the greenhouse effect worse (E)...trees take in carbon dioxide and produce oxygen.”可知，自然因我们每年砍伐大面积的森林而遭受破坏，这使得温室效应更严重，因为树木是吸收二氧化碳并产生氧气的。前后句意存在因果关系，空白E处应是because，引导原因状语从句。故填as；because。
