  • 第2题：

    We can learn from the fourth paragraph that

    [A] a substantial cut in annual revenue is called for.

    [ B] defense and social welfare programs should undergo cuts.

    [ C] we should leave intact programs for bettering people's living.

    [D] we should exercise less control over monetary policy.


    正确答案：A
    43．A【精析】该题为细节题。根据第四段第四句“To be significant， the 1981 budget should be cut by at least 20 billion dollars from 616 billion President Carter proposed.”可以看出，为了显著改善通货膨胀情况，1981年卡特总统提议的6160亿的政府预算应该至少减少200亿，即应该大量减少税收来改善通货膨胀情况，故A项符合文意；根据第四段最后一句“It's impossible if you save defense and all the programs indexed for changes in the cost ofliving．”可以看出，我们不可能通过减少国防投入和节省改善大众生活条件项目的资金来减少政府预算，故B项的表述错误；第四段没有关于如何改善人民生活的表述，故不选择C项；根据第四段第一句 “You have to start with revenue and monetary restraint.”可以看出，为了控制通货膨胀，我们应该增强对税收及货币政策的限制，而 D项的表述与文意相反，故不选择D项。

    Weight on and off the Earth We are so used to.our life on the surface of the earth that it can be quite an effort for our mind to break free of all the ideas that we take for granted.Because we can feel that things are heavy,we think of "weight"as being a fixed quality in an object,but it is not really fixed at all.If you could take a one-pound packet of butter 4,000 miles out from the earth,it would weigh only a quarter of a pound. Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space?The reason is this:all objects have a natural attraction for all other objects;this is called gravitational attraction.But this power of attraction between two obects gets weaker as they get farther apart.When the butter was at the surface of the earth,it was 4,000 miles from the center.When we took the butter 4,000 miles out,it was 8,000 miles from the center,which is twice the distance.If you double the distance between two objects,their gravitational attraction decreases two times two.If you treble the distance, it gets nine times weaker(three times three)and so on. So this is one of the first things we need to remember that the weight of an object in space is not the same as its weight on the surface of the earth. What about the weight of our pound of butter on the surface of the moon?At the distance the puii of the earth is about 4,000 times smaller than it is here on the surface,so we can forget all about the earth-pull on our butter. On the other hand,on the moon there will be an attraction between the butter and the moon,but the butter will weigh only about one-sixth as much as it does on the earth.This is because the moon is so much smaller than the earth.The amount of gravitational pull that a body produces depends on the amount of material in it.A packet of butter has a gravitational pull of its own;but this is very small in relation to the pull of something as large as the moon,or the earth,or the sun.

    How much would four pounds of tea weigh if it was taken 4,000 miles out from the surface of the earth?
    A:1 pound.
    B:2 pounds.
    C:3 pounds.
    D:4 pounds.

    答案：A
    解析：
    第一段最后一句表明，1磅重的黄油在离地球表面4000英里处重达0.25磅，第二段第一句也表明在4000英里高空处的物体重量仅为其在地球表面的重量的1/4。由此可推算出，4磅重的茶叶在离地球表面4000英里处重达1磅。
    第一段第一句表明，我们之所以不能打破固有思维，是因为我们已经习惯了地球上的生活，也就是说，我们正是因为太过熟悉地球上的事物，才没有去质疑这些固有思维。
    第一段第二句表明，物体的重量并非固定不变。第二段解释说，物体的重量源于物体间的引力。也就是说，物体的重量随着物体间引力的改变而改变。
    最后一段第三句说明一个物体产生的引力与物体本身的重量有关。最后一段第四句又表明由于本身重量较小，一包黄油产生的引力很有限，相对于月球、地球、太阳等产生的强劲引力来说，比较容易被我们忽略。
    本篇文章通篇讲的是重量是由引力产生的，并进一步阐述了物体间引力的变化、物体本身的重量，以及物体间的距离这三者之间的关系，主要讲的还是引力对重量的作用。
