    A group of frogs was traveling through the woods and two of them fell into a pit(坑). All the other frogs gathered around it and watched as the two frogs tried to jump out. The pit was very deep and it looked as if there was no way      , so they started yelling at the two frogs to       . "The pit is too deep. You will die," they said together. When the       frogs kept trying, the crowd yelled      . After a while, one of the frogs believed what the others were saying, and fell down and      .
    But      , the second frog kept jumping hard       the negative remarks of those that kept yelling at her to accept the       and just die. Finally, with one big leap, she       it out of the pit! 
    In fact, the second frog was       and unable to hear what the others had been saying. She thought they had been       her on the entire time they were yelling! What she had       considered as encouragement       her to try harder and succeed. And that made all the      ! 
    With a positive       and being deaf to others' opinions, the second frog reached her goals by using such       as encouragement, instead of being       by others like the first frog, who failed to develop her       to struggle for survival.      , when we overcome others' criticism or       comments, we can do anything we set our minds to, just as the second frog did.

    试题分析：两只青蛙同时掉入一个深坑，上面的青蛙劝他们放弃，一直认命死了，而另一只不信，拼命跳，终于挑出了深坑。由此我们知道：无论别人说什么，请一定别放弃自己的奋斗目标。努力一定会成功。

    小题7:考查介词辨析。前后对比可知，另一只不管别的青蛙怎么喊就是一直跳。Besides除了…还有；for为了、因为； despite尽管；except除了…。（整体去除部分）。故选C。
    小题8:考查名词辨析。 这里应该是劝她任命吧。problem问题；life生活；chance机会；fate命运。故选D。
    小题9:考查动词辨析。 终于，用一大跳她跳出了深坑。make it表示做成； jumped  跳；took out   拿出；saved挽救。故选A。
    小题10:考查形容词辨析。从后面解释说她听不到可知是聋子。dumb哑的；deaf聋；lame瘸；blind瞎。故选B。
    小题11:考查动词辨析。她认为他们在给她加油助威所以一直跳。calling打电话、喊；holding抓；cheering 加油；pushing推。故选C。

    小题13:考查动词辨析。她认为的鼓励在激励她一直跳。let让；attracted吸引；inspired激励；kept一直。故选C。
    小题14:考查名词辨析。前后两只青蛙对待他人的意见的反应的差异导致了结果大相径庭。 make a difference产生差异。result结果；difference差异；achievement成就；progress进步。故选B。
    小题15:考查名词辨析。 用了积极的态度以及对他人的态度听不进使得第二只青蛙达到了目标。 expression表达; emotion感情； soul心灵；attitude态度。故选D。

    Rachel Carson, born in rural Pennsylvania in 1907, had a great impact on the environment. Carson earned a master’s degree in zoology in 1932. It was as a writer and not as a research scientist, however, that she made her mark, sharing her view that human beings are just one element in a larger natural order.
    In the articles on natural history Carson wrote for various publications, she expressed dry facts in poetic and persuasive language. She wrote five books. Two of them, The Sea Around Us and The Edge of the Sea, have been called “biographies of the ocean.”
    Carson also made the world aware of how scientific discoveries can harm as well as help living things. In her best-selling book Silent Spring, Carson challenged the profligate use of chemical pesticides by large agricultural and government organizations. She was the first to detail how the pesticide DDT had entered the food chain and damaged populations of bald eagles, falcons, and brown pelicans by causing the shells of their eggs to become so thin that they could not withstand the weight of the parent bird.
    Carson died of cancer in 1964. Today, the Rachel Carson Council collects and disseminates (散播) information on pesticide-related issues. In 1970, the Rachel Carson Wildlife Refuge, a large area of salt marsh and freshwater habitat in Maine, was dedicated to her memory.
    小题1:Which of the following words is closest to the meaning of the underlined word in paragraph 3 ?
    A．excessiveB．inadequateC．authoritativeD．efficient
    小题2:Which of the following inferences is correct ?
    A．Carson wrote books that the average person could understand.
    B．Dangerous properties of new chemical products may be immediately apparent.
    C．If not for Carson, no one would have learned about the dangers of DDT.
    D．In 1970, large quantities of salt and freshwater were dedicated to Carson’s memory by the Rachel Carson Wildlife Refuge
    小题3:Which of the statements below expresses the main idea of the passage ?
    A．Writers have played an important role in the battle against pollution.
    B．The scientist Rachel Carson taught people about environmental issues through her writing.
    C．Carson’s book Silent Spring changed the way some pesticides were used.
    D．Many of Carson’s books were about pesticide-related issues.

    I wish there would be a way to describe China in simple terms but that’s impossible. For the most part Chinese people are friendly, easy-going and optimistic. They are curious and unusually patient and they are also the hardest-working people I have ever met.
    In China, family is everything. In my English classes when the students were asked what they would do if they only had a few hours to live, most students told me how they would spend their last few hours with their families and parents. Many times the subjects in the classes center on families and friends. I teach many students a year, talking to them freely.
    The cost of living here is very low compared with that of the US. The city of Xiang Fan I live in isn’t large and I live better. Non-imported(非出口的) foods are very cheap, so are clothing and articles of everyday use. The cost of public transportation is very low, too. Chinese value education. However, it is reported that many children can’t afford the expenses of schooling and are forced to leave school in some poor area in China. But they organized Project Hope many years age. It creates conditions for the poor children to go back to school. In my opinion, Project Hope is of great importance to the development of the rural education.
    When we read news of China in the west, rarely, if ever, will we see anything mentioned of the positive changes China has gone through. While it is true that economic miracles have not reached many areas of China, but we also have the same problems.
    When I am asked which country I consider better. China or the US, my answer has always been the same, “We are not worse or better than each other, we are only different.”
    小题1:What does the author think of Chinese people?
    A．He thinks most Chinese people hardly work.
    B．He thinks most Chinese people are proud.
    C．He praises most Chinese people a lot.
    D．He dislikes most Chinese people.
    小题2:What is the author doing in China?
    A．He is visiting the places of interest.
    B．He is teaching English in a school.
    C．He is studying in a college.
    D．He is on business.
    小题3:What are not cheap in China in the author’s opinion?
    A．Clothes and shoes made in China.B．Local foods
    C．Public transportation tickets.D．Imported foods
    小题4:We can infer from the passage that the author thinks________.
    A．the westerners have got to know China well
    B．China’s economic miracles have appeared everywhere
    C．the progress of China is seldom reported in the US
    D．the education in rural areas is never cared about in China
    小题5:In the author’s eyes,________.
    A．China is different from the US
    B．China is better than the US
    C．Americans are richer than Chinese
    D．China bears great similarities to the US

    My father was Chief engineer of a merchant ship, which was sunk in World War II. The book
    Night of the U-boats told the story.
    Memories
    In September, 1940, my mother, sister and I went to Swansea, where my father’s ship was getting ready to sail. We brought him a family photograph to be kept with him at all times and keep him sail.
    Then I remember my mother lying face down, sobbing. She had heard from a friend that the ship had been sunk by a torpedo(鱼雷).
    I can remember the arrival of the telegram(电报),which in those days always brought bad news. My grand- mother opened it. It read, “Safe, Love Ted.”
    My most vivid memory is being woken and brought down to sit on my father’s knee, his arm in a bandage.
    He was judged unfit to return to sea and took a shore job in Glasgow for the rest of the war. For as long as I can remember, he had a weak heart. Mother said it was caused by the torpedoes. He said it was because of the cigarettes. Whichever, he died suddenly in his early 50s.
    Ten years later I read Night of the U-boats and was able to complete the story.
    Torpedo
    One torpedo struck the ship. Father was in the engine room, where the third engineer was killed. He shut down the engines to slow the ship making it easier for it to be abandoned.
    By the time he got on deck (甲板) he was alone. Every lifeboat was gone except one which had stuck firm. When he tried to cut it free it swung against the ship, injuring his hand and arm. He had no choice but to jump—still with the photograph in his pocket.
    Three days later, he and other survivors were safe in Glasgow. All 23 with him signed the back of the photograph.
    In my room is the book and the photograph. Often, glass in hand, I have wondered how I would have dealt with an explosion, a sinking ship, a jump into a vast ocean and a wait for rescue? Lest（以免）we forget, I have some more whisky and toast the heroes of the war.
    小题1:We can infer(推断) that the mother and children went to Swansea ________.
    A．to meet a friend
    B．to see the father off

    Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease（疾病） called beri-beri. He was going there to try and find a cure.
    At first, Eijkman thought some kind of germ (细菌) caused beri-beri. He raised some chickens. He didn’t eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精炼米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins (维生素). The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person’s food.
    Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don’t, they can also take vitamin pills.
