标题: prep 1-24

24. (25819-!-item-!-188;#058&002130)

Employment costs rose 2.8 percent in the 12 months that ended in September, slightly less than they did in the year that ended in the previous quarter.

(A) less than they did

(B) less than it did

(D) lower than

(E) lower than they were

这道题目选A没什么问题，因为要用less than而不能用lower than。可是，我的问题是A里面用了they，这里感觉应该用those更好啊。不是有过好几道题目都是因为比较对象用了they错了吗？

请NN指教，谢谢拉

这里不用those,而应该用they.

they 指代的就是Employment costs，即同样的事物的比较，但是处于不同的时间。

those一般和介词或限定性定语从句一起使用，指代不同事物的相同比较方面。

如：

Many teenagers undergo stress, but results of a recent study indicate that the patterns of stress that girls experience are more likely to result in depression than are those that boys experience.

Immigrants from the Mideast exhibit rates of entrepreneurship exceeding those of virtually every other immigrant group in the increasingly divers United States economy.

如果原题改成了employment costs of 1998...是不是就必须用those了？
