1.What is the 'biggest city in the world? That is, (21) city has the largest population? This seems like (22) question to answer, but actually it isn't.It's actually rather difficult to say which cities (23) the largest. There are two reasons for this difficulty. First of all, it isn't easy to determine a city's boundaries, that is, where a city ends. Nowadays, nearly all cities have a large (24) area around them. So when we talk about the population of a city, we often mean the population of the whole metropolitan area around the city. That means that it's difficult to determine what the population of a city is because it's difficult to define what a city is.The second reason that it is difficult to 25 the population of different cities is this: it is almost impossible to get (26) about the population of all cities for the same year. For example, we might get an estimate of New York's population in 1979 and an (27) of Mexico City's population in 1981. So we real ly can't compare the numbers because the information is for (28) different years. And the population of cities changes rather quickly, especially in some cases. For example, the population of Jakarta, Indonesia, may increase by 5% each year, so the population figure will change rather quickly.So we can say that these are our two (29) for comparing the populations of cities: one, it's difficult to determine the (30) of a city, and two, it is difficult to get accurate information.21. A. whatB. whichC. whereD. how

  • 第1题：

    Which of the following statements is NOT true?

    A) World population is increasing at a rate of 150 per minute.

    B) Lower death rates also contribute to world population growth.

    C) The population of Columbia has been doubling every year for 21 years.

    D) The United States is usually doubling its population about every 87 years.


    正确答案：C
    答案：C
    [试题分析] 事实判断题。
    [详细解答] 根据第三段第一句World population is increasing at a rate of 9,000 per hour．可判断A世界人口每分钟增加150人正确；根据该段第二句This is not only due to higher birth rates，but to lower death rates as well．可判断B论断正确；而由第四段的Some countries，such as Columbia， Thailand，Morocco，Costa Rica，and the Philippines．are doubling their populations about every twenty-one years可判断， C哥伦比亚人口持续21年每年翻一番的论断混淆了事实，论断错误；D美国人口每87年翻一番可根据第三段第二句The United States is doubling its population about every eighty-seven years一句判断为正确论断。因此，本题答案为C。

    The population of Boomtown doubles every 18 months. In January of 2000, its population was exactly 12, 000. At this rate, approximately when should the population reach 96, 000?

    C

    January 2006

    D

    July 2007

    E

    January 2012


    正确答案： E
    解析：
    因为2000年，人口数量为12,000，每18个月增长一倍，所以第1个18个月增长到24000，第2个18个月增长到48, 000，第3个18个月增长到96,000，所以也就3个1年半时间，也就是需要4年6个月时间，人口增长到96,000。因为按这个速度开始增长的起始时间为2000年1月，所以那时候为2004年7月。

    Which statement is true about Malta’s immigrant population?
    A

    It has a large immigrant population.

    B

    Its immigrant population is more than 3,000.

    C

    Its immigrant population totals 7,000.

    D

    Its immigrant population comes to less than 1% of the island’s 400, 000 population.


    正确答案： B
    解析：
    该段录音中指出Malta（马尔地）是一个人口密集的国家，但是移民数量却依旧很小，官方指出他们尚无确切的统计，但是估测移民人口在3000以下，而这一数字是“less than 1% of the island’s 400, 000 population”，因此选项D正确。
    【录音原文】
    Malta may be densely populated (three times more than the Netherlands), but its immigrant population is still tiny. Officials say they have no precise total, but their estimate is below 3, 000—fewer than the commonly touted figure of 7, 000 arrivals since 2002, and less than 1% of the island’s 400, 000 population. Malta’s EU partners could be forgiven for feeling that, as in other respects, the union’s southernmost member is just catching up with them.
