What does the author imply by saying "living space ... is figured ... also in cubic volume above the earth" in Para. 3
A．We need to take some measures to protect space.
B．We must preserve good living conditions for both birds and land animals.
C．Our living space should be measured in cubic volume.
D．Our living space on the earth is getting smaller and smaller.
正确答案
B
解析
[解析] 由第三段倒数第二句中的for most of man's fellow creatures on this planet可推断，而且我们保护生存空间是为了其他动物。而且我们不仅要保护平面的空间(square)，还要保护立体的空间(cubic)，这是分别对文中未提及的陆地动物和空中动物(鸟类)而言。正确表述这一意思的是[B]，理解文中的man's fellow creatures是解题的关键。[A]中的protect space涉及范围太广。[C]是根据in cubic volume设计的于扰项；[D]在文中未提及。
The author's attitude towards the current situation in the exploitation of natural resources is ______.
A．critical
B．neutral
C．positive
D．suspicious
正确答案
A
解析
[解析] 从文章中作者论述的前人对保护自然资源的无知和文章中体现的作者保护环境的急切心理可以推断，作者对目前自然资源的利用情况是持批评态度的，故[A]正确，而排除[C]positive“积极的；肯定的”。文中有很多明确表达作者观点的话，故[B]“持中立态度”错误。[D]的意思是“表示怀疑的”，为明显错误的选项。
The desire to make education subservient to the desires of industry is attractive because ______.
A．the goals are easier to define and measure
B．some people take a wider view of education
C．economic competition is so intense these days
D．youth are lacking the skills to compete in the modern economy
正确答案
C
解析
[解析] 此题考查使教育服从于工业需要之所以受人瞩目的原因是什么。subservient是超纲词，但是可以根据构词法进行猜测：前缀sub意为“在…下”，词根serv意为“to serve(服务)”，后缀ient是常见的形容词后缀，由此可知subservient意为“服从”。第二段第一句中的education must ...training the youth ...to compete in such markets和第三句中making education the handmaiden of the job market指的是同一件事情，即使教育服从于工业需要。而这种现象的原因是第二段第一句中的the US is seen as being in desperate, almost cut-throat competition with industrial neighbors，因此选项[C]符合题干要求。desperate“绝望的，孤注一掷的”，cut-throat“竞争激烈的，无情的”。
To avoid the mistakes of our forefathers, the author suggests that ______.
A．we plant more trees
B．we return to nature
C．natural sciences be taught to everybody
D．environmental education be directed to everyone
正确答案
D
解析
[解析] 文章第三段首先提到我们应该改正祖先的错误，然后指出了解决办法：Conservation should， therefore，be made a part of everyone's daily life，接下来又介绍了一些具体的环保知识，由此可推断我们应该对每个人都进行环境保护教育，故[D]正确。最后一段倒数第三句提到We need to be taught the duty of planting trees as well as of cutting them，[A]与此矛盾。[B]在文中找不到合理的依据。[C]与文章意思不符，自然科学并不等同于环保教育。
According to the author, the greatest mistake of our forefathers was that ______.
A．they had no idea of scientific forestry
B．they were not aware of the significance of nature study
C．they had little or no sense of environmental protection
D．they had no idea of how to make good use of raw materials
正确答案
C
解析
[解析] 由文章第一段第三句Our forefathers had no idea that human population would increase faster than the supplies of raw materials; most of them ...had the foolish idea that the treasures were ”limitless” and ”inexhaustible” 可推知，以前的人很少有或没有环境保护意识，他们认为各种资源是取之不尽，用之不竭的。 [A]、[B]和[D]都只是他们缺乏环境保护意识的一个方面，不具有概括性。

A．the importance of the proper use of land
B．the interdependence of water, soil, and living things
C．the value of the beauty of nature
D．the harmfulness of soil destruction and river floods
正确答案
B
解析
[解析] 由第二段第四句We need to know why all watersheds need the protection of plant life and why the running current of streams and rivers must be made to yield their full benefit to the soil ...可知，水、土壤和生物是相互依赖的，而这正是我们在改正前人的错误做法基础上需要做的事情，这说明以前的人没意识到这一点，故[B]正确。该段主要讲了水、土壤和生物之间的相互依赖关系，[A]和[D]都是第二段的内容，与题干不符，[C]在文中未及提。

The disagreement child-centred advocates have with the economic aim of education stems from ______.
A．their training background
B．their beliefs about children and how knowledge derives
C．their distaste of the economic system
D．their view of their role as a trainer not a transmitter of knowledge
正确答案
B
解析
[解析] 题干中的child-centred advocates出现在文章第三段第五句：这些提倡教育以孩子为中心的人 see the curriculum(课程) as based on each individual child's experiences and interests，这反映了how knowledge derives(知识的来源)；而该句中的each being active, involved, unique constructors of their own reality则说明了their beliefs about children，因此选项[B]符合题意。

A．school curriculum should have some relationship to economics
B．knowledge is to be perceived as preserving a nation's cultural history
C．knowledge is to be transmitted
D．students must learn how to be businessmen
正确答案
A
解析
[解析] 文章第三段第二句提到It sees the child as a being to be trained to fit into this economic machine，此处的“指代本段第一句的内容，即题干中的think education should serve the economy。持有这种观点的人认为，孩子们应该被训练来适应经济这台机器。本段第四句又指出The teacher ...is seen as a trainer, a constructor，a transmitter，即老师的作用就是传播(能服务于商业的)知识，选项[A]“学校课程的设置应该与经济有一定联系”符合题意。选项[B]与题干中的态度相反；选项[C]是根据第三段第四句设汁的干扰项；选项[D]在原文中找不到明确依据。
