题目

He could do nothing except ____ TV.A watched B to watched Cwatching D watches
I can run ____ to catch up with you.
A enough fast B enough quickly C fast enough D slowly enough

答案

1.应该是watching 因为当excpet作为介词用时,后面只能跟名词、动名词、名词短语和作为名词的从句（e.g.what I have written）.也就是说,严谨地说,except后面可以跟doing,而不能用to do或do
2.C 因为enough+名词 或形容词/副词+enough
