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。
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。
It can be inferred from the third paragraph that earlier generation didn't realize ______.
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。
