非謂語動詞中分詞的體有完成體和進行體，即having done, having been done和being done，完成體只用于做狀語的場合，而進行體可以用于做定語和做補足語。

　　動名詞的體也有having done, having been done和 being done的結構主要用于做主語和賓語的場合。

　　不定式的體有to be doing 和to have done，主要用于pretend, happen, seem, appear, be said to等結構中。如：

　　① The man in the corner confessed to _____ a lie to the manager

　　of the company.(1997.6)

　　A. have told B. be told C. being told D. having told

　　having told在句中做介詞賓語，表示動作發生在謂語動詞之前。

　　② I'd rather read than watch television; the programs seem ____

　　all the time.(1997.1)

　　A. to get worse B. to be getting worse

　　C. to have got worse D. getting worse

　　從all the time的使用可以推斷get worse是一個漸變過程，所以用不定式的進行體。

　　③ The speech _____ a lively discussion started.(1995.1)

　　A. being delivered B. was delivered

　　C. be delivered D. having been delivered

　　該結構屬于獨立主格結構做時間狀語，狀語分詞所表示的動作發生在謂語動詞之前，所以應該用完成體，答案為D。
