A Chinese man called Cai Lun invented paper almost 2,000 years ago. He made it from wood. He took the wood from trees and made it into paper. He then put these pieces of paper together and made them into a book.
Now paper still comes from trees. We use a lot of paper every day. If we keep on wasting so much paper, there will not be any trees left on the earth. If there are no trees, there will be no paper. Every day, people throw away about 2,800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting nearly 48,000 trees every day. Since it takes more than 10 years for a tree to grow, we must start using less paper now. If we don’t, we will not have enough time to grow more trees to take the place of those we use for paper.
So how can we save paper? We can use both sides of every piece of paper, especially when we are making notes. We can also use cotton handkerchiefs(手帕) and paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant does give us a paper bag, we can save it and refuse(拒绝)it later.
Everyone can help to save paper. If we all think carefully, we can help protect trees. But we should do it now, before it is too late.

Disasters happen all the time somewhere in the world. Are you ready if one hits your neighborhood next week? Find out what you need to do now before it is too late. Let’s take an earthquake for example.
During an earthquake, get under a strong object like the kitchen table. Don’t leave the building during the shaking, or you might be hurt by falling objects from the outside of the building.
When you are in bed during the night and an earthquake happens,simply roll off the bed. There will be a safe void around the bed.
If you are watching TV and you cannot easily run away by getting out through the door or window, then lie down and curl up(蜷伏) next to a sofa, or a large chair.
Never go to the stairs. The stairs are likely part of the building to be broken. Even if the stairs are not destroyed by the earthquake,they may fall down later when people run down.
Try to get into an open area away from trees,buildings,walls,advertisement boards and power lines if you are outdoors.
If you are driving when an earthquake suddenly happens,just stay in your car until the shaking ends. However, if the footbridge falls and breaks your car,get out of it and sit or lie next to it. All the broken cars have voids 3 feet high next to it.
【小题1】 What should you do if you are in a building when an earthquake happens?
A.Rush out quickly | B.Sit in the kitchen |
C.Stay below strong objects | D.Go down the stairs |
A.space | B.seat | C.distance | D.sign |

In the 13th century, the Italian traveler, Marco polo , traveled a long way to China , During his stay in China , he saw many wonderful things . One of the things he discovered was that the Chinese used paper money . In western countries , people did not use paper money until the 15th century . However , people in China began to use paper money in the 7th century .
A Chinese man called CaiLun invented paper almost 2000 years ago. He made it from wood . He took the wood from trees and made it into paper . He then put these pieces of paper together and made them into a book .
Now paper still comes from trees . We use a lot of paper every day ! If we keep on wasting so much paper , there will not be any trees on the earth . If there are no trees , there will be no paper . Every day , people throw away about 2800 tons (吨) of paper in our city . It takes 17 trees to make one ton of paper . This means that we are cutting nearly 48000 trees every day . Since it takes more than 10 years for a tree to grow , we must start using less paper now . If we don’t , we will not have enough time to grow more trees to take the place of those we use for paper .
So how can we save paper ? We can use both sides of every piece of paper , especially when we are making notes .We can choose drinks in bottles instead of those in paper packets . We can also use cotton handkerchiefs (手帕) and not paper ones . When we go shopping , we can use fewer paper bags . If the shop assistant does give us a paper bag, we can save it and reuse it later .
Everyone can help to save paper . If we all think carefully , we can help protect trees . But we should do it now , before it is too late .
