OG181及188

1. Because of the enormous research and development expenditures required to survive in the electronics industry, an industry marked by rapid innovation and volatile demand, such firms tend to be very large.

(A) to survive

(B) of firms to survive

(C) for surviving

(D) for survival（B）

(E) for firms’ survival


The subject of the main clause (such firms) presumes a prior reference to the firms in question. Furthermore, the logical subject of to survive and the logical complement of required should be made explicit. All three demands are met by B, the best choice. Choices A, C, and D, with no reference to the firms in question, meet none of these demands. In choice E, the illogical and awkward use of a prepositional phrase (for firms’ survival) buries the needed initial reference to firms in a possessive modifier.


其中的黑体部分， 是指required的逻辑补充部分吗？


2.

188. As a result of medical advances, many people that might at one time have died as children of such infections as diphtheria, pneumonia, or rheumatic fever now live well into old age.

(A) that might at one time have died as children

(B) who might once have died in childhood

(C) that as children might once have died

(D) who in childhood might have at one time died（B）

(E) who, when they were children, might at one time have died


B, the best choice, uses the preferred relative pronoun, who, to refer to many people. It observes formal and logical parallelism in the wording of the relative clause and the main clause: first, adverbs (once and now), second, verbs (might have died and live); and third, adverbial prepositional phrases (in childhood and into old age). A and C use the questionable relative pronoun that to refer to many people. They also violate the parallel structure noted above. D and E, although they use the correct pronoun, who, offer convoluted and nonparallel structures for the relative clause.


是不是说many people后面不能跟that,为什么？
