86. Since 1986,when the Department of Labor began to allow investment officers’ fees to be based on how the funds they manage perform, several corporations began paying their investment advisers a small basic fee,with a contract promising higher fees if the managers perform well. (A) investment officers’ fees to be based on how the funds they manage perform,several corporations began (B) investment officers’ fees to be based on the performance of the funds they manage,several corporations began (C) that fees of investment officers be based on how the funds they manage perform,several corporations have begun (D) fees of investment officers to be based on the performance of the funds they manage,several corporations have begun (E) that investment officers’ fees be based on the performance of the funds they manage,several corporations began Verb form +Logical predication Since l986 indicates action begun in the past and continuing into the present, and the form of the verb must show that continuity, as the present perfect tense does:since 1986,corporations have begun.The pronoun they lacks a referent.While they would seem to refer to investment officers’ , grammatically it cannot because investment officers’ is a possessive modifying fees, rather than a plural noun standing by itself. The sentence needs to be revised so that investment officers is a plural noun. A Have begun should replace began;they has no referent. B Have begun should replace began;they has no referent. C Allow that…be based on is not a correct idiom;it should be allow…to be based on. D Correct.Substituting fees of investment officers in this sentence allows the pronoun they to refer to the officers;have begun properly indicates a continuing situation. E Allow that…be based on is an incorrect idiom;they has no referent;began does not indicate the continuity necessary after since 1986. The correct answer is D. 此句的解释中说到THEY 的指代问题。我没有看懂是什么意思,大家可以帮我解释一下吗?还有C答案里,为什么Allow that…be based on is not a correct idiom;it should be allow…to be based on.是错的呢?我查了语法书是该这么写啊。后面的SHOULD什么的省略了吧.大家可以帮忙吗? |
