Can trees talk? Yes, but not in words. Scientists have reason to believe that trees do communicate (交际) 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 (信号) causing its neighbors to change the chemistry of their own leaves and make them less tasty.
Communication, of course, doesn’t 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 shouldn’t trees have ways of sending message?
小题1: It can be concluded from the passage that caterpillars do not feed on leaves that ______.
A.are lying on the groundB.have an unpleasant taste
C.bees don’t likeD.have an unfamiliar shape
小题2:According to the passage, the willow tree was able to communicate with other trees by ______.
     
A.waving its branchesB.giving off a special smell
C.dropping its leavesD.changing the colour of its trunk
小题3:According to this passage, bees communicate by ______.
A.making special movementB.touching one another
C.smelling one anotherD.making unusual sound

The afternoon on December 25 in the waiting room , I was the nurse on duty . When I felt sad about having to_36_on Christmas Day , a woman and four small children showed up at my desk .
“ Are you all sick ?” I asked. “ Yes,” the woman said _37_and lowered her head. But when it came to telling me about their_38_ ,things got a little surprising. They all seemed to be well and there was nothing _39_ with their body.
Why did they tell a _40_that they were all sick? I did not say anything but _41_ that it might be a little time before a doctor could _42_ them . The mother said,“Take your time.We can _43_ here. It’s so warm.” When she finished the register chart , I noticed she didn’t write down their address----were they _44_ ?
I looked at the _45_ around the Christmas tree. The children were excited and _46_ to be healthy. The littlest one was pointing at the Christmas tree and say something to the mother. Then I was sure that they came here not because of _47_ but only for warmth.
I went back to the nurses’ station and _48_ the homeless family. The nurses, _49_ about working on Christmas Day like me, turned to feel sorry for the family and decided to _50_.
We bought delicious food in the hospital restaurant and _51_ a big dinner for our guests. We needed _52_. So we put apples in a basket and collected candies and clothes. Just as we were seriously prepared to meet the physical needs of the _53_, our team worked to meet the needs of a family who just wanted to be _54_ on Christmas Day.
Later, as the family was to _55 _ , the youngest child ran to me and said,“Thank you very much. Good bye.’

My mother used to ask me what was the most important part of the body. Through the years I would   21  what I thought was the correct answer. When I was younger, I thought   22  was very important to us as humans, so I said, “My ears, Mommy”. She said, “No. Many people are   23 . But you keep thinking about it and I will ask you again soon.”
Several years passed   24  she asked me again. Since making my first   25 , I had often thought of the correct answer. So this time I told her, “Mommy, sight is very important to everybody, so it must be our eyes.” She looked at me and told me, “You are   26  fast, but the answer is not correct because there are many people who are blind.”
  27  the years, Mother asked me a couple more   28  and always her answer was, “No, but you are getting   29  every year, my child.” Then last year, my Grandpa died. Everybody was crying when it was our   30  to say our final good-bye to Grandpa. Mom asked me, “Do you know the most important body part yet, my dear?”
I was   31  when she asked me this now. I always thought this was a   32  between her and me. She saw the   33  on my face and told me, “This question is very important. It shows that you have really   34  your life.” I saw her eyes well up with tears. She said, “My dear, the most important body part is your   35 .” I asked, “Is it because it holds up your head?” She replied, “No, it is   36  on them a crying friend or loved one can rest their head. I only hope that you have enough   37  and friends that you will have a shoulder to cry   38  when you need it.” Then and there I knew the most important body part is not a   39  one. It is sympathetic to the pain of   40 .

The right to pursue happiness is issued to us all with our birth, but no one seems quite sure what it is.
A holy man in India may think that happiness is in himself. It is in needing nothing from outside himself. If wanting nothing, he lacks nothing. We westerners, however, are taught that the more we have from outside ourselves, the happier we will be, and then we are made to want. We are even told it is our duty to want. Advertising, one of our major industries, exists not to satisfy these desires but to create them---and to create them faster than any man’s money in his pocket can satisfy them. Here, obviously someone is trying to buy the dream of happiness and spending millions upon millions every year in the attempt. Clearly the happiness-market is not running out of customers.
I doubt the holy man’s idea of happiness, and I doubt the dreams of the happiness-market, too. Whatever happiness may be, I believe, it is neither in having nothing nor in having more, but in changing --- in changing the world and mankind into pure states.
To change is to make efforts to deal with difficulties. As Yeats, a great Irish poet once put it, happiness we get for a lifetime depends on how high we choose our difficulties.
It is easy to understand. We even demand difficulty for the fun in our games. We demand it because without difficulty there can be no game. And a game is a way of making something hard for the fun of it. The rules of the game are man-made difficulties. When the player ruins the fun, he always does so by refusing to play by the roles. It is easier to win at chess if you are free, at your pleasure, to cast away all the rules, but the fun is in winning within the rules.
The same is true to happiness. The buyers and sellers at the happiness-market seem to have lost their sense of the pleasure of difficulty. Heaven knows what they are  playing, but it seems a dull game. And the Indian holy man seems dull to us, I suppose, because he seems to be refusing to play anything at all.
The western weakness may be in the dreams that happiness can be bought while eastern weakness may be in the idea that there is such a thing as perfect happiness in man himself. Both of them forget a basic fact: no difficulty, no happiness.
小题1:Who shares the same idea of happiness with the author?
A.The Indian holy manB.The great Irish poet Yeats
C.AdvertisersD.The buyers and sellers at the happiness-market
小题2:What does “happiness-market” mean in the second paragraph?
A.It means a place in which people can buy things happily
B.It means a market which lacks happy customers
C.It means a pure state for the world and mankind
D.It means a market where people try to buy happiness with money.
小题3:According to the passage, which of the following is Right?
A.The Indian holy man is much happier than westerner.
B.The westerners understand happiness better than the Indian holy man.
C.There is no fun without playing by the rules
D.Both the eastern weakness and western weakness are the same.
