其实JJ没什么好补充的, 之前的前辈们整理的很完整了饿. 今天碰到了一道GWD有争议的题目,发现个问题,一上来几道的SC真是狂难,后来的SC狂简单,弄的我很郁闷.而且阅读也是,一上来的一篇很难,后面几篇相对简单点了. 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 我还是选了A 还有一道SC的题目,我也不是很确定 大概是这样的 the economy of the United States...........that of +几个country的名字 those of+几个country的名字 不知道这2个选什么,因为好象economy可以是复数的, 所以应该用those,但是前文的economy是单数,所以应该用that指代. 不过后来我还是选了that of 的那个 |
