    After years of study, I have known there are only two types of people in this world: those who get to the airport early and those who arrive when the plane is about to take off.

    If there were any justice（公正）in this world, early-airport people would be rewarded for doing the right thing. And late-airport people would be punished. But early-airport people get ulcers（溃疡）, heart attacks and bite their fingernails to the bone. Late-airport people almost don’t realize they are flying.

    A guy of that kind once said, “Don’t hurry. If you miss your flight, it’s because God doesn’t want you to go.” This is clearly a guy who is never going to get an ulcer.

    Early-airport people suffer another “name”. They are called exactly what they are -wimps（窝囊废）. I know. I was an early-airport person for years. “My baggage will get on the plane first,” I told myself. Indeed it would, which made it the last baggage they took off the plane after landing.

    Another strange thing: No matter how early I showed up, I was always told that someone had called two or three years ahead of me and asked for the best seat. I thought it was a trick. I thought there was someone in America who called every airline every day and said: “Is that wimp Simon flying somewhere today? If he is , give me his seat.”

    After a lifetime arguing with my wife over whether I really have to pack 24 hours in advance and set the alarm clock four hours ahead, I have learned another fact about early-airport people and late –airport people:

    They always marry each other.

    We can learn from the passage that     .

    A. late-airport persons are often nervous

    B. early-airport persons are always at ease during the flight

    C. early-airport persons get their baggage first after the landing

    D. late-airport persons always take things easy

    Paragraph 5 mainly wants to tell us that      .

        A. someone always plays tricks on the writer

        B. the airlines usually fool passengers

    C. early-airport persons always can’t get good seats

    D. the service of airlines is very bad

    This passage is written in order to     .

    A. give readers tips about taking a plane

    B. offer suggestions about having a good plane trip

    C. express the writer’s anxiety about taking a plane

    D. show people’s different attitudes toward catching planes

    It could be inferred that the writer’s wife is     .

    A. an early-airport woman               B. a late-airport woman

    C. a hot-tempered woman                 D. a sensitive woman

    填空（共10小题：每小题1分，满分10分）

    阅读下面短文，根据所读内容在文后第76至第85小题的空格里填上适当的单词或短语，并将答案转写到答题卡上。

    注意：每空不超过3个单词。

    The best thing you can say about the roofs of most city buildings is that you don’t have to look at them much. That’s very good, since and urban landscape viewed from above can be and unlovely thing－block after block of tarred（铺有沥青的）black rooftops, sticky in summer, windswept in winter, ugly year-round. Or at least that’s the way it used to be.

    But urban roofs are going green. Environmental designers have begun to realize that the tops of buildings don’t have to be wastelands. Indeed, they can be gardens, planted with grasses, flowers and bushes.

    A planted roof usually comes in one of two varieties: extensive or intensive. The extensive type is wide and shallow, with a soil depth of less than 8 inches, able to support smaller plants, The intensive type may be smaller, but it’s relatively deeper and home to larger plants.

    Whatever the design, green roofs are not so simple as ordinary gardens. They have multiple layers beneath the soil, including a drainage layer, waterproofing, structural support, and so on .

    But this system can do a great deal of good. A recent paper in the journal BioScience tells that green roofs can control temperature, contain water and clean the air. And most impressively, they can cut heat loss from a building by 50%, lower air-conditioning costs by 25%, and reduce the urban-heated-island effect by 2℃.

    Of course, apart from the square feet greened and heat reduced, green roofs are even more valued since people can gain some psychological comfort simply by having a quiet place to go. As so often happens, what’s good for the planet can also be good for the spirit.

    健康问题一直是生活中的热点话题。尤其对于女性来说，你知道穿矮高跟鞋和纯粹的高跟鞋对你身体健康的影响吗？

    Healthy knees aren't the main consideration in choosing high heels, but new research says chunky heels are just __________as spindly stilettos（细高跟鞋）.

    "It takes a long time to feel the effects of knee osteoarthritis（骨关节炎）— and once you do, it is too late," said Dr. Casey Kerrigan, leading researcher of the study and associate professor at Harvard Medical School's department of physical medicine.

    "I compare it to smoking — one cigarette is not painful, but over a lifetime it is. Wide-heeled shoes feel comfortable, so women wear them all day long, "Kerrigan said.”They are better for your feet than stiletto heels, but just as had for your knees.”

    The idea that high heels are bad for your health isn't new — scientists have warned women for years that they contribute to problems ranging from corns to hammer toes, tendonitis, knee pain, sprained（扭伤）ankles and back problems.

    But in 1998, Kerdgan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis, a painful joint disease that destroys cartilage（软骨）surrounding the knee.

    The first study looked only at stiletto heels, and Kerrigan said she wanted to study the chunky high-heeled shoes she noticed many women wearing.

    "This study confirms what we all intuitively（直觉地）know that high-heeled shoes of any kind are not good for our health," said Dr. Glenn Pfeifer, a San Francisco doctor and member of the American Academy of Orthopedic Surgeons who was not connected to the study.

    1. What’s the main idea of the passage?

                                                                               

    2. Which sentence in the passage is the closest in meaning to the following one?

    In my opinion, it is similar to smoking, for smoking one cigarette does little harm but if you smoke all your life, it’ll be very painful.

                                                                              

    3. Please fill in the blank in the passage with proper words or phrases to complete the sentence.（within ten words）

                                                                              

    4. What do you think of wearing the chunky heels according to the passage? （within 30 words）

                                                                               

    5. Translate the underlined sentence into Chinese.

    It is reported, some needy students receive financial support from some kind people but never express our thanks. Personally, I think they are wrong. Though the helpers didn’t expect any reward in return, it is necessary and good manner to say “thank you”. Besides, it is a basic social skill express ourselves in modern society. Maybe some of them do feel thankfully. It is only because they are afraid of looked down upon which they remain silent. But I just want to say that being poor for a moment doesn’t means you will be poor forever.
