OG11th-12

12. After gradual declension down to about 39 hours in 1970, the workweek in the United States has steadily increased to the point that the average worker now puts in an estimated 164 extra hours of paid labor a year.

(A)            After gradual declension down

(B)           Following a gradual declension down

(C)           After gradual declining down

(D)           After gradually declining

(E)           Following gradually declining

D IS Correct. 我的问题是：（D）After gradually declining 中的  After  是什么词性呢？

如果做介词 后面只能跟名词性短语之类吧？

after是介词,但是这也不影响d的正确性啊,介词后可以跟名词,也可以跟动词的ing形式

这题主要错误在于declension 和down是reduncdant

介词用法没错啊,好像 I talked to my mom before going to school.这里before是介词+ going.

哦 那
            After gradually declining应该是省略形式吧？ 省略了主语和谓语 变成了介词+分词的形式？
