4.Passage TwoQuestions 26 to 30 are based on the following passage.Certain animals and plants develop characteristics(特性)that help them cope with their environment better than others of their kind. This natural biological process is called adaptation(适应性). Among the superior characteristics developed through adaptation are those that may help in getting food or shelter,in providing protection,and in producing and protecting the young. That results in the evolution of more and more organisms that are better fitted to their environments.Each living thing is adapted to its way of life in a general way,but each is adapted especially to its own distinct class. A plant,for example,depends upon its roots to fix itself firmly and to absorb water and inorganic chemicals. It depends upon its green leaves for using the sun's energy to make food from inorganic chemicals. These are general adaptations,common to most plants. In addition,there are special adaptations that only certain kinds of plants have. Many animals have adaptations that help them escape from their enemies. Some insects are hidden by their body color or shape,and many look like a leaf or a little branch. The coats of deer are colored to mix with the surroundings. Many animals have the ability to remain completely still when an enemy is near.Organisms have a great variety of ways for adapting. They may adapt in their structure,function,and genetics(遗传素质);in their development and production of the young;and in other respects. An organism may create its own environment,as do warm-blooded mammals. which have the ability to adjust body heat exactly to maintain their ideal temperature despite changing weather. Usually adaptations are an advantage,but sometimes an organism is so well adapted to a particular environment that,if conditions Change,it finds it difficult or impossible to readapt to the new conditions.Some plants and animals develop superior characteristics so that they may______.A. help others of their kind get food,shelter and other things neededB. get into the biological process of adaptationC. become better adapted to the environments than others of their kindD. lead to the evolution and production of more and more organisms

    正确答案:B

    [试题分析] 推理题。
    [详细解答] 根据文中最后一段中的句子They also do equally well at programming a computer,which is neither visual nor spatial.说明了B项“给计算机制定指令”不属于视觉和空间能力,因此,正确答案应为B。

  • 第3题:

    Which of the following statements is NOT mentioned in the passage?

    [A] Radical reforms are essential for the increase of productivity.

    [B] New ways of organizing workplaces may help to increase productivity.

    [C] The reduction of costs is not a sure way to gain long term profitability.

    [D] The consultants are a bunch of good-for-nothings.


    正确答案:A
    49. [A] 意为:激进的改革对生产率的提高极其重要。
       首先要看清楚题目,是说文章未提到的,大家一定不要犯这种低级错误,选了文章提到过的选项。,作者只指出促进生产率革命的措施并未奏效,未达到人们想象的效果,而并末提到应该如何才对。这属于过度引申的干扰项。
       B 意为:用新方法改变工作场所可以提高生产率。第三段第二句指出,重新改变工作场所仅是加快一个国家的国民经济综合生产率水平(overall productivity of an economy)的一种措施,促进生产率发展的因素还有许多,如:设备和机器投资、新技术、教育和培训投资等都会带来生产率的提高。
       C意为:降低成本并不能保证带来长期利润。根据第五段第三句,在比尔看来,许多公司机械地(in a mechanistic fashion)应用改革措施,降低了成本,但对长期盈利却考虑不够。可见,降低成本和长期盈利并非总是成正比。 
       D 意为:顾问们是一伙饭桶。不要以为这种骂人句肯定不会出现在原文中,那你就犯了主观主义错误了。文章最后一段指出,在罗森伯格看来,目前负责经济调整的顾问们所做的工作,多数都是垃圾(没有成效),是典型的“于事无补”。

    正确答案: A
    解析:
    是非题。最后一段最后一句提到“the orderliness of the system makes it possible for the country to weather high unemployment and social unrest without a sense of crisis”,该句中的weather意为“经受住,度过(难关)等”,由此可知丹麦的井井有条有助于这个国家更好地应对高失业率和社会动乱,并不是指井然有序减少了失业率。因此选项D表述有误。

    解析:
    根据文章的第一句话“Certain animals and plants develop characteristics that help them cope with their environment better than others of their kind.”可以比较容易地得出正确答案是C。


    在不认识“environments”的情况下,我们可以通过上下文来猜侧该词的意思。根据第一段内容,主要讲什么是生物适应,其实根据常识也可以判断,适应无非是针对生存环境而言的,那么可以初步断定“environments”意为“环境”。而A项contexts意为“上下文,语境”,C项neighbors意为“邻居”,D项enemies意为“敌人”,都不符合题干要求。B项surroundings出现在倒数第二段“The coats of deer are colored to mix with the surroundings.”因此正确答案是B。


    根据第三段的第二句“Some are hidden by their body color or shape, and many look like a leaf or a little branch.”可以判断,动物一般用羽毛或者体表颜色来达到把自己隐藏在环境中的目的,因此答案是D。


    根据最后一段的第二句话“They may adapt in their structure, function, and genetics;” 可知,A、B、C三项都在文中直接被提到。


    根据最后一段的第三句“An organism may create its own environment, as do warm-blooded mammals,which have the ability to adjust body heat exactly to maintain their ideal temperature despite changing weather.”可以比较容易地得出正确答案是A。
