Yes, but not in words. Scientists have reason to believe that trees do communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree attacked in the woods by caterpillars (毛虫) changed the chemistry of its leaves and made them taste so terrible that they got tired of the leaves and stopped eating them. Then even more astonishing, the tree sent out a special smell-a signal causing its neighbors to change the chemistry of their own leaves and make them less tasty.Communication, of course, doesnt need to be in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar (花蜜) for honey. So why shouldnt trees have ways of sending message?(1)、Its implied that caterpillars do not feed on leaves that have an unpleasant taste.A：TB：F答案： A(2)、The willow tree described in the passage protects itself by growing more branches.A：TB：F答案： B(3)、The willow tree was able to communicate with other trees by giving off a special smell.A：TB：F答案： A(4)、It can be inferred from the passage that bees communicate by making special movements.A：TB：F答案： A(5)、The author holds that the incident described in the passage must be checked more thoroughly.A：TB：F答案： B2、 In the United States, it is not customary to telephone someone very early in the morning. If you telephone him early in the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires immediate attention. The same meaning is attached to telephone calls made after 11:00 pm. If someone receives a call during sleeping hours, he assumes its a matter of life or death. The time chosen for the call communicates its importance.In social life, time plays a very important part. In the U.S.A. guests tend to feel they are not highly regarded if the invitation to a dinner party is extended only three or four days before the party date. But it is not true in all countries. In other areas of the world, it may be considered foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten. The meaning of time differs in different parts of the world. Thus, misunderstandings arise between people from different cultures that treat time differently. Promptness is valued highly in American life, for example. If people are not prompt, they may be regarded as impolite or not fully responsible. In the U.S. no one would think of keeping a business associate waiting for an hour, it would be too impolite. A person, who is 5 minutes late, will say a few words of explanation, though perhaps he will not complete the sentence.
