From the story, we know John is a ______.A. busy personB. quiet personC. helpful personD. lucky personCDo you know that animals have love for each other and their children just like us humans? Let me tell you some moving stories of great animal parents.Several years ago a heavy rain hit a town and made the river go up. When the rain stopped, people found that a dog swam to an island in the river twice a day for two weeks. Why did she do so? Her four children were there. The mother swam there every day to feed her babies.This true story moved many people.Another story is about chimpanzees(猩猩). A scientist named Jane Goodall spent l4 years living with chimpanzees in Africa.She found that chimpanzees also cared for those that were hurt or got lost.“It is not only humans who have duties, animals also do,” she said.Two birds in Chengdu also showed their parental love. Their baby was hurt and fell on the street in the center of the city.Cars were driving past but the brave parents rushed down to the road and took the little bird away with their claws(爪子).( ) 38.

The two birds rushed down and took the little one away because .A. they didn't like their babyB. they were not kind enoughC. they wanted to teach their babyD. they wanted to save their baby( ) 41. From the passage we know .A. dogs like to swim across the river in a heavy rainB. mother birds don’t want to save their childrenC. animal parents love their children a lotD. all animals want to move people very muchDPeople didn’t use to throw things away. They used to mend their clothes and reused them until they wore out.When they bought things,they used to carry shopping baskets. But now we don’t reuse things well and more rubbish has been produced. We throw away 25 million tons of waste in our dustbins every year. That means one family throw away about one thousand kilos of waste.We have a strong reason to take it as a serious problem! The fact is that lots of rubbish we throw away could be reused or recycled. The so-called rubbish isn’t really rubbish.The UK is one of the worst recyclers in Europe.In other words,in the UK they’re recycling only about 8%of their everyday waste. That’s much less than many other countries.Germany recycles l0%,while Japan recycles 40%.The government has set a goal of recycling 30%of their everyday waste by the year 2012.But it looks that it is not easy to teach it. As we know, some habits are difficult to change and some collection plans are expensive to carry out.At present,the movement called Recycle Now in the UK tries to change that situation.The top designer Oliver Heath is a strong fan of the movement.In 2005 he designed the first home built completely from recycled things,including metal cans and glass bottles.“It always makes me excited when I make good use of those recycled things,”h e said,“Maybe in the near future,you can also make something from recycled computer printers,plastic bags,bottle tops or CDs."When his story was reported on TV,more and more people begin to try his ideas.Some local governments have set up recycling centre s where it’s easy for families for fam ilies to take their empty bottles and old newspapers.Instead of throwing away the so-called rubbish,some families start doing more about it.With the effort of the whole country,we are happy to see some progress in some places in the UK.( ) 42. Why does the writer think rubbish is a serious problem?A. The UK is one of the worst recycles in Europe.B. People throw away 25 million tones of waste in the dustbins every year.C.
