    　　Destructive insects in larger numbers are finding Alaska forests to be a comfortable home and climate change could be the wel-come mat.

    　　Warmer winters kill fewer insects. Lon-ger, warmer summers let insects complete a life cycle and reproduce in one year instead of two. Warm winters also can damage trees and make them less able to stop insect attacks by changing the nature of snow. Instead of light snow formed at extremely cold tempera-tures, warm winters produce wet, heavy snow more likely to break the tops of spruce trees because they are not well adapted to handling big, heavy, wet snow loads.

    　　Since 1980, spruce bark (树皮) beetles have killed mature white spruce trees on 4. 4 million acres. For lack of two cold winters on end, the numbers of the beetles there blew up while the resistance (抵抗力) of the trees was down at the same time everywhere. Most of the mature trees have been killed in some whole region of the state.

    　　Spruce bark beetles bore into (蛀穿)trunks and feed on the live cambium layer, a thin part of tissue between bark and wood. Trees re-sist beetles with pitch, made up of hydrocarbons including up to 17 forms of terpene (松稀). The rates of those terpenes are a signal of the health of the tree. When a tree is injured, terpene rates go off in one direction.

    　　Using complex chemical receptors (感受 器), spruce bark beetles discover differences in terpenes. Injured trees offer less resistance.

    　　They smell the tree. If the tree's healthy,they try to avoid it Why? If they start to bore into a healthy tree, it's got a lot of pitch, and the pitch is under high pressure. It's boring in and the pitch is pushing it back out.

    (1) What would be the best title for the text?

    [　　]

    A．The Destruction of Forests in Alaska

    B．Warm Winters and Its Bad Effects

    C．The Way of Spruce Trees' Living in Alaska

    D．Destructive Insects on Rise in Alaska

    (2) According to the text, how do warm win-ters reduce the trees' ability to resist in-sect attacks?

    [　　]

    A．By changing the nature of snow.

    B．By offering too much water to trees.

    C．By making the weather drier.

    D．By increasing the insects' growth speed.

    (3) The third paragraph mainly tells________.

    [　　]

    A．winters are warmer and warmer

    B．there are more and more beetles

    C．the situation of trees is much worse

    D．mature trees are easy to be attacked

    When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.

    People who are near-sighted can only see things that are very close to their eyes. Everything else seems blurry. Many people who do a lot of work, such as writing, reading and sewing become near-sighted. People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses, too.

    Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

    Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distances as people with two eyes.

    1.We should take good care of our eyes________.     .

    A．only when we can see well

    B．only when we cannot see perfectly

    C．even if we can see wel

    In spite of our efforts，we seemed to be getting no closer to Mary as the cold，boring March days dragged by. Even my faith was wearing thin. My heart ached so desperately， wanting this child with autism (自闭症) to come alive and be aware of the beauty， the wonder and the fun even if she had the pain of living without her mother.

    Then on a late March day，one of the boys excitedly reported a robin (知更鸟) in the schoolyard. We flocked to the window to see it. "Spring's here!" the children cried. "Let's make a flower border for the room!"

    Why not? I thought. Anything to lift our spir­its. This time the papers we selected were beautiful pastel (颜料) colors，with brown strips to weave in­to baskets. I showed the children how to weave the baskets and how to fashion all the flowers we wel­come in early spring. I placed the beautifully colored papers on her desk and encouraged her to try. Then I left the children to do their own creating，and I spent， the next half-hour sorting strips of paper at the back of the room.

    Suddenly，Kristie came hurrying to me，her face red. “Come and see Mary’s basket,” she cried. “It’s so pretty! You’ll never believe it!” I caught my breath at its beauty. “Mary,” I said .“This is beautiful. How did you ever manage?” She looked at me with the shining eyes of any normal little girl. “My mother loved flowers,” she said simply. “She had all of these growing in our garden. ”

    We fastened her basket in the very center of the border at the front of the room. It remained there until school ended in June. On the last day，Mary held it carefully as she carried it out the door. Then she came running back, pulled a paper crocus (番红花) from her basket and handed it to me. "This is for you," she said， and she gave me a hug.

    I've kept the crocus in my desk ever since-just to remind me of Mary and of the enduring power of love and faith.

    66.What can we learn about the writer from the first paragraph?

    A.She didn't want to get close to Mary.

    B.She thought Mary should leave the school.

    C.She considered that she had tried her best.

    D.She was concerned about Mary.

    67.The writer had the children weave baskets to____.

    A.make them help Mary

    B.develop their creativity

    C.have a coffee break

    D.talk to Mary about her condition

    68.From Kristie's red face. we know she was ____.

    A.angry             B.frightened                  C.depressed                 D.excited

    69.What can we infer from the underlined sentence in the fourth paragraph?

    A.Mary was seriously sick.                                   B.Mary wanted to please the writer.

    C.Mary recovered from illness.                      D.Mary was treated badly.

    70.Which of the following is the best title for the passage?

    A.A miracle has occurred                              B.How lonely a girl will be

    C.Why such a lovely girl is sick with autism    D.A great teacher and her students
