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. [br] A distinguished physician who worked from the 1930s to the 1970s, many new medical techniques, perhaps most notably in the field of epidural steroids, were pioneered by Dr. Marvin Leason.

选项 A、many new medical techniques, perhaps most notably in the field of epidural steroids, were pioneered by Dr. Marvin Leason
B、Dr. Marvin Leason notably pioneered many new medical techniques, perhaps most so in the field of epidural steroids
C、Dr. Marvin Leason pioneered many new medical techniques, perhaps most notably in the field of epidural steroids
D、the field of epidural steroids was perhaps the most notable of the many new medical techniques pioneered by Dr. Marvin Leason
E、perhaps most notable among the new medical techniques pioneered by Dr. Marvin Leason were those in the field of epidural steroids

答案 C

解析 The last phrase of the passage refers to "its diet," so the underlined passage should refer to "the marine iguana" in the singular. Answer E is incorrect because it uses the plural phrase "they search," and B is stylistically inferior to C because the phrase "the marine iguana, being the only species of iguana" is awkward. C is the best choice.
