真题类型:Writing > Improving Sentences 写作--改进句子
Part or all of the following sentence is underlined; beneath the sentence are five ways of phrasing the underlined material. Select the option that produces the best sentence. If you think the original phrasing produces a better sentence than any of the alternatives, select choice A. 下列句子中划线部分,有以下五个表达方式,选择其中一个最适合句子的选项。如果你认为原有的表达比其他选项更合适,就选择A。
Although biologists have made tremendous progress in mapping the human genome, the genetic roots of most common diseases remained largely elusive.
(A) remained
(B) had remained
(C) remain
(D) are remaining
(E) remains
2013年7月8日SAT考试官方每日一题答案:C
解析:
Choice (C) is correct. It avoids the verb tense error of the original. The past tense verb “remained” is not consistent with the present perfect tense verb “have made” and should be changed to the present tense verb “remain.”
