单选题
  • A. Consider
  • B. Considering
  • C. Considered

单选题
  • A. to
  • B. for
  • C. by
  • D. from
【正确答案】 C
【答案解析】[解析] be asked by sb．是典型的被动语态表示法。译文：人们常常问这样的问题，尤其是那些为太空探险缴税的人。因此，C为正确答案。
单选题
  • A. from
  • B. in
  • C. out of
  • D. by
【正确答案】 A
【答案解析】[解析] result本来是名词，是“结果”的意思。作动词用，是不及物动词。result from意为“起因、由来”，句子主语是果，from的宾语是因。result in则刚好相反，是“导致”的意思，句子主语是因，in的宾语是果。result from意为“由……产生”：result in意为“结果是……”；C项out，of，D项by不能和result构成固定短语。根据题意：直到现在，由太空研究所产生的现实效益包括……。因此，A为正确答案。
单选题
  • A. has learned
  • B. has been learned
  • C. is learned
  • D. can learn

单选题
  • A. affective
  • B. efficient
  • C. more affective
  • D. more efficient
【正确答案】 D
【答案解析】[解析] affective意为“感情方面的”；efficient意为“效率高的”。因为上下文都是比较级，由平行结构可推知此处也需用比较级more efficient．因此D为正确答案。
单选题
  • A. improve
  • B. improving
  • C. improved
  • D. being improved
【正确答案】 C
【答案解析】[解析] 本句介词by后面的宾语是三个名词短语。improved意为“被改进了的”，与后面两个better构成平行结构。本句大意为：全世界的人们现在都得益于改进了的天气预测法，更好的交流系统……。因此，C为正确答案。
单选题
  • A. as
  • B. unless
  • C. although
  • D. until
【正确答案】 A
【答案解析】[解析] 此处的连接词as表示“当……时候”，主句用将来时态，从句用一般现在时。unless，although，until与表示承接的意义不符。因此，A为正确答案。
单选题
  • A. observe
  • B. observes
  • C. observing
  • D. to observe
【正确答案】 D
【答案解析】[解析] and后面的成分应该是不定式，因为此处and连接的并列成分是to measure...and to observe…。原句意为“当从太空所做的观察使得测量地球的能源及观察这些能源利用得是否合理成为可能时，人类就会受益”。故D为正确答案。
单选题
  • A. Increasing
  • B. Increased
  • C. Increasingly
  • D. To increase
【正确答案】 C
【答案解析】[解析] increasingly是副词用于句首，表示强调。译文：太空项目将越来越多地帮助我们处理世界的环境问题。故C为正确答案。
单选题
  • A. which
  • B. for which
  • C. among which
  • D. of which
【正确答案】 D
【答案解析】[解析] of which是定语从句连词，先行词system在从句中作of的宾语，正确语意是man is only a part of the complex system。故D为正确答案。
