If it were only necessary to decide whether to teach elementary science to
everyone on a mass basis or to find the gifted few and take them as far as they
can go, our task would be fairly simple. The public school system, however, has
no such choice, {{U}} {{U}} 1 {{/U}} {{/U}}the jobs must he
carried on at the same time. Because we depend so {{U}} {{U}} 2
{{/U}} {{/U}}upon science and technology for our progress, we must produce
specialists in many fields. {{U}} {{U}} 3 {{/U}} {{/U}}we live
in a {{U}} {{U}} 4 {{/U}} {{/U}}nation, whose citizens make the
policies for the nation, large numbers of us must be educated to understand, to
uphold, and when necessary, to judge the work of {{U}} {{U}} 5
{{/U}} {{/U}}. The public school must educate both producers and {{U}}
{{U}} 6 {{/U}} {{/U}}of scientific services. In
education, there should be a good balance {{U}} {{U}} 7 {{/U}}
{{/U}}the branches of knowledge that contribute to effective thinking and
{{U}} {{U}} 8 {{/U}} {{/U}}judgment. Such balance is defeated by
{{U}} {{U}} 9 {{/U}} {{/U}}much emphasis on any one field. This
{{U}} {{U}} 10 {{/U}} {{/U}}of balance involves not only the
{{U}} {{U}} 11 {{/U}} {{/U}}of the natural sciences, the social
sciences and the arts but also relative emphasis among the natural sciences
themselves. {{U}} {{U}} 12 {{/U}} {{/U}}, we must have a balance
between current and {{U}} {{U}} 13 {{/U}} {{/U}}knowledge. The
attention of the public is continually drawn to new {{U}} {{U}} 14
{{/U}} {{/U}}in scientific fields and the discovery of new knowledge; these
should not be allowed to turn our attention away from the sound, established
materials that form the basis of {{U}} {{U}} 15 {{/U}} {{/U}}for
beginners.
单选题
A. whereas
B. though
C. while
D. for
【正确答案】
D
【答案解析】[解析] for“因为”。“for”与文章第一段第三句中的“Because we depend...”构成搭配，均表示解释原因。而选项A，B，C均不用于解释原因，不符合原文意思。
【答案解析】[解析] users“用户；使用者”。根据文章一致性，users与原文第一句中的“a mass basis”形成呼应，且users“使用者”与原文中的producers“生产者”形成一种搭配。而subscribers“购者；订阅者”，passers-by“过路人；路人”，victims“受害者；牺牲品”均不形成一致性，不符合题意。
单选题
A. amid
B. between
C. upon
D. among
【正确答案】
D
【答案解析】[解析] among“在(三者或三者以上)……之间”。根据上下文，上文提到的“science and technology”、“in many fields”以及下文的“the branches of”可知应填入“among”。而amid“在……中间，被……围绕”，between“在(两者)……之间”，upon“在……之上”均不符合题意。
【答案解析】[解析] question“问题”。根据全文的第一句“If it were only...whether...or...”，该句是提问式的句子，是需要做出回答的问题，所以选择question。而incident“小事件；事件”，inference“推论；推理；暗示”，impact“冲击；冲突；影响”均不符合原文意思。
