相关试题

Many kinds of birds live in the United States, but the number of the birds is becoming smaller every year. One of the leading reasons is the growing number of pet cats. By keeping your pet cats in your home, you can help give birds a better possible chance to live.

Of the 90 million pet cats in this country, about two—thirds are allowed to go outside. It is said that these cats kill hundreds of millions of birds each year, as well as billions of small animals such as rabbits and field mice.

They can also bring illness to the animals that live in people's yard(院子), further weakening the health of the natural populations.

Allowing pet cats to go outside is not just bad for birds and wildlife, it's also bad for the cats themselves. Outdoor cats can get sick very easily. They are in danger from traffic and attacks from other animals. In fact, outdoor cats usually don't live past the age of five, while indoor cats often live to be 17 or older.

Keep your pet cat inside! If you raise a young cat, it's your duty to let it play inside.

Country music is one of the most popular kinds of music in the United States today because it is about simple but strong human feelings and events-love, sadness, good times, and bad times.

Today country music is also popular everywhere in the United States and Canada — in small towns and in New York City, among black and white, and among educated and uneducated people. About 1, 200 radio stations broadcast country music twenty-four hours a day. English stars sing it in British English, and people in other countries sing it in their own languages.

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(分解) PET, a form of plastic. PET was first made in the 1940s and is now widely used to make plastic bottles. It can stay 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 found it while examining the structure 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 plastic-eating abilities work faster and better.
John McGeehan, one of the lead researchers, said, "We have made an improved enzyme. It's better than the natural one. And we are trying to make more improvements to it." He went on, "the enzyme is not bad for humans or animals, and it is friendly to the environment. So we are thinking about putting it into wider use."
The team is now trying to make the enzyme break down PET in large quantities (大量的). “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 researchers found that a natural enzyme helped eat plastics ______.
A.in Britain B.in the US C.in Japan D.in China
3.Which of the following 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 bad for humans and animals.
4.The passage is written in a / an______ tone(语气).
A.sad B.hopeful C.angry D.crazy
