动名词的体也有having done, having been done和 being done的结构主要用于做主语和宾语的场合。 不定式的体有to be doing 和to have done，主要用于pretend, happen, seem, appear, be said to等结构中。如：
I’d rather read than watch television; the programs seem ____ all the time.
A. to get worse B. to be getting worse
C. to have got worse D. getting worse
【答案】D。
【解析】从all the time的使用可以推断get worse是一个渐变过程，所以用不定式的进行体。
10）动名词复合结构
动名词符合结构可以做主语、宾语和表语，在对动名词的考查中总是将其逻辑主语包括进来，形成动名词的复合结构：
_____ in an atmosphere of simple living was what her parents wished for.
A. The girl was educated B. The girl educated
C. The girl’s being educated D. The girl to be educated
【答案】D。
【解析】本题涉及题眼比较多，A，为从句做主语，但缺少that，D为不定式做主语，但缺少for(for the girl to be educated)，B结构不能做主语，答案是C，为动名词的复合结构 |
