32、e things. If it continues like this, we shall destroy ourselves.What will happen in the future? Perhaps it is more important to ask What must we do now?

33、to save our world. They plant trees, build bridges across rivers in forests, and so on.

37、of conservation of nature since 1970 BGasoline (汽油) prices are getting higher and higher. The prices make it hard for drivers to afford the fuel.One group held a special event to display（展示）new kinds of cars .The new cars are different and they can run on many different kinds of fuels.Some of these

38、cars are called hybrids(混合動(dòng)力). They can run on different kinds of fuels. One kind of them runs on a special fuel cell which is filled with a gas called hydrogen.

He says we will never run out of the sources of the fuel ,but we may run out of the oil.Once we use oil up, it will take millions of years for more oil to form. Since gasoline is made from oil, that

44、nt remember when I started collecting litter（垃圾）. But it was when I got tired of seeing litter near my home and realized that no one else was going to pick it up.I live close to a forest in Ohio, America. I can walk there in three minutes! I used to love going there to play with my dog. But one day

45、there was so much litter there that I became very unhappy. I decided to clean up the forest. I wanted to feel happy going there again.I made my first trip to clean the forest that afternoon. I took a big black rubbish bag with me. Ten minutes after starting to pick up litter, my bag was full! It had

46、 cans, bottles, broken glass and newspapers in it.Since that first trip three years ago, Ive gone to the forest four times a year to pick up litter. Im often there for three hours. It makes me feel great to do something for the environment.After each trip, I look at all the litter Ive found. If any

47、of it is recyclable（可回收的）, I keep it. I cant understand why people drop litter. But I will keep picking it up until they stop dropping it.I know I can only do a small bit to help the earth, but I still think it is important.41.When did the writer begin to collect litter?AWhen he was very young.

50、ing unwell. This may sound like something someone would say today. But in fact, an unknown person who lived in Rome in AD 53 wrote it. We all love new inventions. They are exciting, amazing and can even change our lives. But have all these developments really improved the quality of our lives? Pictu

51、re this,：Youre rushing to finish your homework on the computer. Your mobile phone rings, a QQ message from your friend appears on the screen, the noise from the television is getting louder and louder. Suddenly the computer goes blank and you lose all your work. Now you have to stay up all night to

52、get it done. How happy do you feel? Inventions have speeded up our lives so much that they often leave up feeling stressed and tired. Why do you think people who live far away from noisy cities, who have no telephones, no car, not even any electricity often seem to be happier? Perhaps because they l

53、ive a simpler live. One family in the UK went back in time to see what life was like without all the inventions we have today. The grandparents, with their daughter, and grandsons Benjamin, 10 and Thomas, 7, spent nine weeks in a 1940s house. They had no washing machine, microwave, computer or mobile phones.
