　　1)动名词作主语
　　Seeing is believing. Talking mends no holes.Taking a cold shower every morning does him a lot good.____in an atmosphere of simply living was what her parents wished for. (CET-4 1999,1)
　　A) The girl to be educated
　　B) The girl educated
　　C) The girl's being educated
　　D) The girl was educated
　　动名词和不定式都可以做主语。不定式做主语表示具体的动作，动名词做主语则可以表示抽象或一般性的动作或情况。根据句意，这个女孩在朴素的生活环境中接受教育是她的父母所希望的，接受教育不是具体的一次性动作，因此用动名词，答案为C。当动名词做主语时，我们常用先行词it作形式主语，而把真正的主语动名词放到句尾，特别要注意如下结构：It is useless (no use, no good, no harm) doing... It is a waste of time doing... It is worthwhile doing...
　　【例如】
　　It is no use crying over spilt milk.It is a waste of time discussing such matters with him.It is no good leaving today's work for tomorrow.
