178. In the last few years, the number of convicted criminals given community service sentences, which allow the criminals to remain unconfined while they perform specific jobs benefiting the public, have risen dramatically.
(A) sentences, which allow the criminals to remain unconfined while they perform specific jobs benefiting the public, have
(B) sentences, performing specific jobs that benefit the public while being allowed to remain unconfined, have
(C) sentences, performing specific jobs beneficial to the public while they are allowed to remain unconfined, have
(D) sentences which allow them to remain unconfined in their performing of specific jobs beneficial to the public has(E)
(E) sentences allowing them to remain unconfined while performing specific jobs that benefit the public has
At issue in this question is subject-verb agreement; the number... has risen must be the kernel of the main clause. Choice E, the best answer, uses a singular verb form, has, to agree with the singular subject, the number. (主谓一致)Choices A, B, and C mistake criminals for the sentence subject (???)and so incorrectly use the plural verb form have. In B and C the verb phrases (performing... ) do not clearly modify criminals, because another noun (sentences) intrudes, (修饰不清)nor do the verb phrases clearly establish temporal relationships among events. (事件的关系不清)D is wordy and imprecise (in their performing of specific jobs). (笨拙不准确)
Choices A, B, and C mistake criminals for the sentence subject (???)这句话如何理解呢 A/B/C的主语不都是the number吗
谢谢
