2. 被動語態的特殊結構形式
1)帶情態動詞的被動結構。其形式為:情態動詞+be+過去分詞。例The baby should be taken goodcare of by the baby-sitter.
2) 有些動詞可以有兩個賓語,在用于被動結構時,可以把主動結構中的一個賓語變為主語,另一賓語仍然保留在謂語后面。通常變為主語的是間接賓語。例His mother gave him a presentfor his birthday. 可改為 He was given a present by his mother for his birthday.
3) 當“動詞+賓語+賓語補足語”結構變為被動語態時,將賓語變為被動結構中的主語,其余不動。例Someone caught the boy smokinga cigarette. 可改為The boy was caught smoking a cigarette.
4)在使役動詞have, make, get以及感官動詞see, watch, notice, hear, feel,observe等后面不定式作賓語補語時,在主動結構中不定式to要省略,但變為被動結構時,要加to。例Someone saw a stranger walkinto the building. 可改為A stranger was seen to walk into the building.
5) 有些相當于及物動詞的動詞詞組,如“動詞+介詞”,“動詞+副詞”等,也可以用于被動結構,但要把它們看作一個整體,不能分開。其中的介詞或副詞也不能省略。
例The meeting is to be put offtill Friday.
