以下是引用joanna143在2006-7-4 18:38:00的发言:In 1981 children in the United States spent an average of slightly less than two and a half hours a week doing household chores; by 1997 they had spent nearly six hours a week.A. chores; by 1997 they had spent nearly six hours a week B. chores; by 1997 that figure had grown to nearly six hours a week C. chores, whereas nearly six hours a week were spent in 1997 D. chores, compared with a figure of nearly six hours a week in 1997 E. chores, that figure growing to nearly six hours a week in 1997
正确答案B,请教E错在哪里? B is the best. it's the year of 2006. Thus, by 1997 + 过去完成时也没错. 前半句的一般过去时是为了说一过去的事实. E is wrong due to its structure, which is sentence,+ N1. (N1= that figure) But "that figure" 不是 chores 的宾同. Moreover, the meaning of "in 1997" is completely different from that of "by 1997". |
