    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。

  • 第13题:

    Text 2 To understand how astrology works, we should first take a quick look at the sky. Although the stars are at enormous distances, they do indeed give the impression of being affixed to the inner surface of a great hollow sphere surrounding the earth. Ancient people, in fact, literally believed in the existence of such a celestial sphere. As the earth spins on its axis, the celestial sphere appears to turn about us each day, pivoting at points on a line with the earth's axis of rotation. This daily turning of the sphere carries the stars around the sky, causing most of them to rise and set, but they, and constellations they define, maintains fixed patterns on the sphere, just as the continent of Australian maintains its shape on a spinning globe of the earth. Thus the stars were called fixed stars.

    The motion of the sun along the ecliptic is, of course, merely a reflection of the revolution of the earth around the sun, but the ancients believed the earth was fixed and the sun had an independent motion of its own, eastward among the stars. The glare of sunlight hides the stars in daytime, but the ancients were aware that the stars were up there even at night, and the slow eastward motion of the sun around the sky, at the rate of about thirty degrees each month, caused different stars to be visible at night at different times of the year.

    The moon, revolving around the earth each month, also has an independent motion in the sky. The moon, however, changes its position relatively rapidly. Although it appears to rise and set each day, as does nearly everything else in the sky, we can see the moon changing position during as short an interval as an hour or so. The moon's path around the earth lies nearly in the same plane as the earth's path around the sun, so the moon is never seen very far from the ecliptic in the sky. There are five other objects visible to the naked eye that also appear to move in respect to the fixed background of stars on the celestial sphere. These are the planets Mercury, Venus, Mars, Jupiter, and the Saturn. All of them revolve around the sun in nearly the same plane as the earth does, so they, like the moon, always appear near the ecliptic. Because we see the planets from the moving earth, however, they behave in a complicated way, with their apparent motions on the celestial sphere reflection both their own independent motions around the sun and our motion as well.

    第26题:The ancient people believed that ________.

    [A] the earth was spinning on the axis of the sky

    [B] the sky was a hollow sphere spinning around the earth

    [C] the patterns of stars on the sky would never change

    [D] the stars around the sky were not stationary


    正确答案:C
    根据第一段最后两句话,我们可以看出古人认为是地球的转动带动了群星的转动,而事实上群星在天空中是恒定的。于是,正确答案应为C。

    According to the passage,"weight"should be understood in the sense that
