题型：不详难度：来源：
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 (柳树) 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 (化学物质) 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.
小题1:Willow trees send messages with_____________.
| A．words | B．movements | C．smells | D．sounds |
| A．树干 | B．嘴唇 | C．枝条 | D．手势 |
| A．speak just as people do | B．tell stories to others |
| C．communicate with each other | D．kill insects in the woods |
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---c | B． d---b---a---c |
| C． a---b---c---d | D． d---c---b---a |
答案
小题1:C
小题2:B
小题3:C
小题4:A
解析
小题1:细节理解题，由文中语句“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.”可知。
小题2:词义推断题，由文中涉及到人类用嘴说话，而树木没有挪动lips而像人一样，故推测是嘴唇。
小题3:细节理解题，由文中语句“some trees do manage to communicate with each other.”可知。
小题4:细节理解题

Passage 5
Here in Siberia (西伯利亚), the winter is always very long and it’s very, very cold! It starts to snow in November and the snow won’t leave until May. The temperature is usually about -25℃, but it’s sometimes much colder. When it’s -35℃, children can’t go to school, but grown-ups still go to work! We wear a lot of warm clothes: socks and boots, sweaters and fur coats. All the houses have heating, so it’s never cold inside. In winter, we close the windows to stop the wind from getting in, and we don’t open them again until spring.
In spring and summer it rains a lot, and we don’t often see the sun. In summer it’s often about 25℃, but the weather is very changeable. One day it’s 25℃, and the next day it’s 10℃. People say that the weather was even colder in the past.

小题2:What are used in Siberia to keep the people and houses warm?
小题3:Do children go to school when it’s -35℃ in winter?
小题4:What’s the weather like in spring?

Passage 6
According to the Center of Disease Control and Prevention (CDC) (疾病控制中心), if you don’t often wash your hands, you can pick up viruses (病毒)from many places and make yourself ill. You’re at risk every time you touch your eyes, nose or mouth. In fact, one of the most common ways people catch colds is by rubbing their noses or their eyes when there are cold viruses on their hands. If you don’t often wash yours hands, specially when you’re sick, you may spread the viruses directly to others. You should wash your hands in the following situations:
After using the bathroom
After blowing your nose or coughing
Before eating, serving or preparing food
After touching pets or other animals
After visiting anyone who is sick
When your hands are dirty
There is a right way to wash your hands. Follow these simple steps to keep your hands clean.

What does a UFO look like? Do you believe there are aliens outside the earth? Maybe nobody can tell us exactly, but some of us believe that we humans are not alone in this world. We have friends living outside the earth. And a lot of people in the world think they really have seen a UFO flying in the sky. Now many scientists are trying to understand the origin of the UFO sightings. Scientists even try to draw pictures about aliens and aliens’ life according to their imagination.
Because we don’t really know about it, we call it UFO or Unidentified Flying Object. Many of us are curious(好奇的) about it and interested in it very much.
While scientists have no same ideas about whether there is an alien or not, it seems that China has been home to some UFO sightings recently.
On August 20th,2011, a UFO was seen at 21:00 by the pilot on the plane which took off from Pudong International Airport to Changchun. At almost the same time, many astrophiles(天文爱好者)took pictures of it. Later, reports from some cities said that the UFO was seen. The pilot said the UFO was small at first, then expanded(扩大),moved north, and disappeared(消失)several minutes later. However, he couldn’t exactly make sure about what he had seen.

Can you make animals work for us? Some scientists think that one day we can teach animals to do a lot of things for people. In a film shown on TV, you may see elephants, monkeys, tigers or some other animals are always given a little food to eat after they have done something. Scientists say that people can teach many different animals to do some of the easy work if they know they will get something to eat. We all know elephants can carry large logs(圆木)，and dogs can look after houses. And we even teach animals to work in factories. In America, for example, people have used apes to help make cars and scientists think that those large monkeys may drive trains one day. Now people are trying to get them to do the same thing that man does.
