依稀记得新东方老师说过than后面不能直接加时间状语，这个题的正确选项A作何解亚？

843. The use of chemical pesticides in this country is equally extensive or more so than ten years ago.

(A) equally extensive or more so than ten years ago

(B) equal to or more extensive than ten years ago

(C) as extensive as ten years ago or more

(D) equal to, if not more, than ten years ago（E）

(E) as extensive as it was ten years ago, if not more so

这个题我选的是B，错误的原因似乎就是因为than后面不能加时间状语地说。。

我觉得843和764还是有区别的，843than前边没有出现时间状语now,因此than后的ten years ago也就缺少了比较对象
