专题11非谓语动词
Part1语法精讲
Section1非谓语动词做主语 ( -ing/-to do)
1. 如果表语是不定式,主语也是不定式;表语是动名词,主语也是动名词。如:
To see is to believe.=Seeing is believing.
2. 动名词作主语的句型。如:
It is no use/no good/useless doing sth.
It is a waste of time doing(也可用It is a waste of time to do)
3. 动词不定式和动名词的复合结构:
动词不定式的复合结构有两种:It is difficult/easy/possible/necessary/...for sb. to do sth.和It is kind/wise/foolish/considerate/...of sb. to do
动名词的复合结构是由名词所有格或“物主代词+动名词”构成。在口语和非正式语体中,只要不是作主语,动名词复合结构中的逻辑主语常采用名词通格或人称代词宾格。如:
His coming made me happy.
I can't imagine his/him living there alone.
4.动名词被动式作主语(过去分词不可作主语)。如:
Being exposed to the sunlight for a long time does harm to your skin.
