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

nn能不能解释下这几个选项的错误啊？这种题目我总是出错。多谢了！

答案是B

那么过去完成时怎么解释呢。。

toneere

C D E都不能选,改变了原句意思.
原句不是在讲1997年发生的事情,而是讲到1997年为止的事情,

既然用了by结构,就应该用完成时,那不用过去完成时用什么?难道用现在完成时?1997年已经过去很多年了

A.
chores; by 1997 they had spent nearly six hours
a week (they 指代有问题, 如果指代children的话会令句子出现逻辑错误: 1997年还是1981年那帮孩子吗?)

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 (无逻辑或语法上的错误, 但相比选项B, 被动表达不如主动, 并改变句子重心)



D.
chores, compared with a figure of nearly six hours a week in 1997 (compared with没有与a figure对应的逻辑主语)

E.
chores, that figure growing to nearly six hours a week in 1997 (growing无法表达出完成的状态)
