We talk every day. When we have good news, we like to share it with our good friends and when something terrible happens, we tell it to others soon. But can you imagine that a tree can talk and share news too ? Of course, no tree moves lips and says words just as people do. Strange as it may sound, though, some trees do manage to communicate with each other.
Willow (柳樹) trees are the best-known of these trees. When insects begin nibbling (叮咬) a willow tree, the tree sends out a special smell at once. This smell tells the other willows that harmful insects are coming near. All of them quickly make a chemical (化學(xué)物質(zhì)) in their leaves. This chemical is bad to the insects. The insects do not like it and they fly away soon. In this way, the willow trees protect themselves from the insects.
The next time when you take a walk in the woods, maybe the trees are “talking” to each other quietly. And when someone says that trees cannot “talk”, please tell them that even trees give messages to each other, too.
【小題1】Willow trees send messages with_____________.
A．wordsB．movementsC．smellsD．sounds
【小題2】The underlined word “l(fā)ips” in the first paragraph means _____________.
A．樹干B．嘴唇C．枝條D．手勢
【小題3】The passage tells us that some of the trees can _____________.
A．speak just as people doB．tell stories to others
C．communicate with each otherD．kill insects in the woods
【小題4】According to the passage, the right order of the following is _____________.
a.  The willow tree gives out a smell.
b.  The willow trees make a chemical in their leaves.
c.  Insects fly away because of the chemical.
d.  Insects begin nibbling a willow tree.
A． d---a---b---cB． d---b---a---c

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 (噸) 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 .

         Forests have always been useful and important to men who make use of them in many ways. Every day trees are serving man everywhere. Trees supply man with fruits and building materials in the form of wood. Without trees it would be impossible to build houses, boats, bridges and so on. Furniture such as desks, chairs and beds is made of wood. Trees can stop man from the terrible heat. They’re also useful in preventing(阻止) good and rich top soil from being washed away during heavy rains. If there were no forests, heavy rains would wash away the rich surface(表層) soil that is so important to plants. The result is that the land will become a desert. There are plenty of desert areas in the world. A long time ago these desert areas used to be very rich areas, but men in the past had no enough knowledge about science of nature, and they cut down too many trees in the area where they lived and never planted new ones. By and by, the rich surface soil was blown and washed away by strong winds and heavy rains. In the end the rich land changed into useless deserts where nothing could grow.

根據(jù)短文內(nèi)容，判斷正（T）誤（F）。

1.Trees are not serving man everywhere.

2.Without trees it would be possible to build houses, boats, bridges and so on.

3.Trees can stop man from the terrible heat.

4.There are few desert areas in the world.

5.In the end the rich land changed into useless deserts where nothing could grow.
