问题     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【S1】______, for the two jobs must be carried on at the same time. Because we depend so【S2】______upon science and technology for our progress, we must produce specialists in many fields.

    In education there should also be a good【S6】______among the branches of knowledge that contribute to effective thinking and wise judgment. Such balance is defeated by too much【S7】______on any one field. This question of balance【S8】______not only the relation of the natural sciences, the social sciences, and the arts but also relative emphases among the natural sciences themselves.【S9】______, we must have a balance between the current and classical knowledge. The attention of the public is continually drawn to new possibilities in scientific fields and the discovery of new【S10】______; these should not be allowed to turn our attention away from the sound, established materials that form the basis of courses for beginners.

选项
答案D
解析 动词用法辨析。该句缺少谓语动词，由于句子主语是单数，所以该谓语动词应该是“-s”的形式。此外，语境的大概意思为“这种学科的平衡不仅涉及到各种学科之间的平衡，而且还涉及到某一个学科本身内部的平衡”。据此，可以确定该动词为involves。故，[D]为该题答案。
