　　SAT官方每日一题之写作---改进句子：

　　Writing > Improving Sentences

　　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.

　　Bore she became a major rock star capable of filling stadiums, shesingsin little-known clubs and as a back-up singer for other acts.

　　(A) sings

　　(B) has sung

　　(C) is singing

　　(D) had sung

　　(E) has been singing

　　The correct answer is D

　　Explanation

　　Choice (D) is correct. It avoids the verb tense error of the original by providing the past perfect tense verb phrase “had sung” to indicate an action that was completed bore another action (e.g., “became a major rock star”) in the past.

　　下面是一道和SAT官方每日一题相似的题目，供大家练习：

　　(A) many of them are

　　(B) many of which are

　　(C) many are

　　(D) which are, many of them,

　　(E) and many of them that are

　　The correct answer is B

　　Explanation

　　Choice (B) is correct. It avoids the comma-splice error of the original by using the pronoun “which” in place of the pronoun “them,” thereby turning what was originally an independent clause (“many of them are … United States”) into a relative clause that modifies “songs.”
