    【题目】根据板块构造学说的观点，下列说法正确的是

    A.地中海的面积在不断扩大，最终将会形成新的海洋

    B.东非大裂谷在不断缩小，最终将消失

    C.板块的内部地壳比较稳定，板块交界地带地壳活跃，多火山地震

    D.太平洋的面积还在不断扩大，大西洋的面积在不断缩小

    【答案】C

    【解析】

    根据地质学家经过长期研究，提出了板块构造学说。板块构造学说认为，地球岩石圈是由板块拼合而成的。全球主要有六大板块，其中太平洋板块几乎全部是海洋，其余板块既包括大陆，又包括海洋。海洋与陆地的相对位置是不断变化的，进行分析解答。

    地中海位于板块的碰撞挤压处，面积在不断缩小，故A错误；

    东非大裂谷在不断扩大，未来可能将会形成新的海洋，故B错误；

    板块的内部地壳比较稳定，板块交界地带地壳活跃，多火山地震，故C正确；

    太平洋的面积还在不断缩小，大西洋的面积在不断扩大，故D错误。

    故选C。

    【题目】You may have heard of the famous saying, "East or West, home is the best.” What does the word "home" mean to you? How do you say the word in French, in Chinese, in your language? Although people usually know what the word means, it sometimes has no exact translation（翻译）. It's not surprising, because the idea of home is different from country to country, and from person to person. A home is more than a roof and four walls. It's the cooking, eating, talking, playing and sleeping that go on inside. And at home you usually feel safe and relaxed.

    Homes look different in different countries. They also have different things inside. For example, in cold northern Europe, there's a fire in the living room or kitchen and all the chairs face it. In the south, where the sun shines a lot and it's more important to keep the heat out, there are small windows and cool stone floors.

    We asked some people about their homes.

    How often do people move house in your country?

    "In my country many people don't stay in one place for a very long time. They often move every ten years or so. "

    -- Chery, Boston, USA

    What are features (特征) of homes in your country?

    "In Britain, even in town, there's always a garden. We have separate bedrooms and living rooms. But we don't often have balconies (阳台). The weather isn't warm enough! "

    --Pat, Exeter, England

    A. making friends B. cooking and eating

    C. playing and talking D. sleeping and relaxing

    【3】Why is it important to keep the heat out of the houses in southern Europe?

    A. Because the sun there shines a lot.

    B. Because there's a fire in the living room.

    C. Because they wear heavy clothes all day long.

    D. Because they want to breathe fresh air outside.

    A. how old they are B. the climate（气候）they have

    C. whether they are rich or not D. whether they live in the city or countryside

    【5】What can we learn from the passage？

    A. Homes look the same in different countries.

    B. Some Americans move house several times during their lifetime.

    C. People in Britain seldom have balconies because it's so hot outside.
