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
(C) less than they were
(D) lower than
(E) lower than they were 正确答案是A。我选的D。不是有规定,说在比较句中,如主谓结构相同,则主谓可省,只保留状语从句或介词短语么。
例如:i work harder than i worked in the past。=i work harder than in the past。但为什么D不对呢?期待解答~~~~
