Scientists in Britain and the United States have made a new kind of enzyme(酵素) that eats plastics (塑料). With its help, plastics can be turned into smaller parts and go away quickly. Scientists believe that, in the future, it could solve the problem of plastic pollution.
The enzyme is able to break__down PET, a form of plastic. PET was first made in the 1940s and is now widely used to make plastic bottles. It can remain in the environment for many years and pollute large areas of land and water. So it has always been a headache to deal with the waste from PET and other plastics.
The researchers made the discovery(发现) while examining the structure of a natural enzyme in Japan. They found that the natural enzyme was helping to break down PET plastics. So, they decided to make small changes to the enzyme by adding some amino acids(氨基酸). It made the natural enzyme's plasticeating abilities work faster and better.
John McGeehan, one of the lead researchers, said, “We've made an improved enzyme. It's better than the natural one. And we are trying to make more improvements to
5
it.” He went on, “The enzyme is not harmful to humans or animals, and it is friendly to the environment. So we are considering putting it into wider use.”
The team is now trying to make the enzyme break down PET in large quantities(大量地). “We'll see that the plastic pollution may be stopped with this technology. However, there is still a long way to go，” John McGeehan added.
( )1.According to the scientists, the enzyme may solve the problem of ________ pollution.
A．air B．water
C．light D．plastic
( )2.The underlined phrase “break down” in the passage probably means “________” in Chinese.
A．实验 B．生产
C．发明 D．分解
( )3.Researchers discovered that a natural enzyme helped eat plastics ________.
A．in Britain B．in the US
C．in Japan D．in China
( )4.Which of the following is TRUE according to the passage?
A．The scientists are still trying to improve the enzyme.
B．The enzyme will pollute large areas of land and water.
C．The natural enzyme works better than the improved one.
D．The natural enzyme is harmful to humans and animals.

One day, a baby snail(蜗牛) found that he had to carry a big and heavy shell at any time. He was confused(困惑的), so he went up to his mother and asked, “Why was I born with a shell that grew so hard and heavy？” His mother said, “Because we don't have bones to hold us up. We can only move slowly, so we need a shell to protect us.”
The baby snail asked again, “The caterpillar(毛毛虫) has no bones, either, and she can't move quickly. Why can she live without a shell？” The mother snail answered, “That's because a caterpillar will become a butterfly(蝴蝶). She can fly high into the sky. They sky can protect her.”
The baby snail had one more question, “But the earthworm(蚯蚓) moves like us. He has no bones and he won't turn into a butterfly. Why doesn't he carry a hard and heavy shell？” His mother said, “He can dig a hole and hide in the ground, and then the earth can protect him.”
The baby snail then cried, “We are so poor! We have no protection from the sky or from the ground！” His mother smiled at him, “That's why we have a shell. My dear, imagine that if we don't have the shells, what will happen to us? Hot sun will dry out our bodies and we'll have nowhere to sleep. What's worse, we'll die in the heavy rain. How terrible it is! We don't depend on the sky or the ground for protection. We should depend on ourselves.”
