问题 The following questions present a sentence, part of which or all of which is underlined. Beneath the sentence, you will find five ways of phrasing the underlined part. The first of these repeats the original; the other four are different. If you think the original is best, choose the first answer; otherwise choose one of the others.
   These questions test correctness and effectiveness of expression. In choosing your answer, follow the requirements of standard written English; that is, pay attention to grammar, choice of words, and sentence construction. Choose the answer that produces the most effective sentence; this answer should be clear and exact, without awkwardness, ambiguity, redundancy, or grammatical error.

E、of Americans born before 1925, only 8 percent of them have developed obesity by the age of 65, but 35 percent of those born since 1950 do by the age of 35
答案 C
解析 A is confusing, both because of its wording and because of its confusion of tenses: "develop" and "did so." B and E also mix tenses. The presentation of facts in D is confusing, and its use of the present tense is inappropriate for data that concern the past. C is the best answer.
