...不可直接接动词不定式形式,但可接how [who, where, when, whether, etc.] to do形式。如:She knows how to drive. 她懂得怎样驾驶(汽车)。He knew how to express his thoughts.
他知道怎样表达自己的思想。I know where to go. 我会认路。通常不说:* She knows ...
...者是动名词作真正的主语。比如:
It’s hard to finish the work in such a shgort time.
= It’s hard finishing the work in such a short time.
我想知道,除 hard 还有哪些词语可以这样用,即前面用 it 作形式主语,后面可用不定式或动名...
