Thepassivevoice不用于被动语态的情形2

不及物动词没有被动语态因为不及物动词没有宾语,所以若将其用于被动语态则没有主语,故不能用于被动语态.这类动词如takeplace,happen,comeabout,breakout,appear,dispear,last(持续）,arise(出现，发生），datefrom(datebackto)等．e.g.Thestormhaslastedfor3hours.Theboydisappearedroundthecorner.3

get+过去分词e.g.Howdidthatwindowgetopened?Cleaningwomeninbigcitiesusuallygetpaidbythehour.4

主动表被动的若干情形１.连系动词(如look,sound,smell,feel,taste,prove等)用主动表被动,因为系动词为不及物动词,它们没有被动形式.e.g.Thegardenlooksverybeautiful.Youideaprovedtobewrong.5

2.当open,close,shut,lock,move,read,wash,clean,cook,cut,wear,carry等用作不及物动词且表示主语的某种属性时,通常用主动表被动.e.g.Thewindowwon’tshut.Thebooksellsquickly.6

3.不定式toblame,tolet用作表语时,主动表被动.e.g.Whoistoblame?Thehouseistolet.7

4.某些be+adj+todo结构中的不定式通常用主动表被动．e.g.Thepoemisdifficulttounderstand.Themusicisn’tpleasanttolistento.Thepictureisinterestingtolookat.8

5.不定式用于某些动词（如have,havegot,get,want,need等)的宾语后作定语时,如果不定式的逻辑主语是句子的主语,通常用主动表被动.e.g.Ihavesomeclothestowash.Ihavesomethingtodrink.9

6.在too…todosth和…enoughtodosth这两个结构中,若句子的主语与其后的不定式为被动关系,则该不定式通常用主动表被动.e.g.Thewritingistoofainttoread.Theseboxesarenotstrongenoughtouseasaplatform.10

7.beworth后的动名词用主动表被动．e.g.Thismovieisworthseeing.Sheisnotworthgettingangrywith.8.在need,want,require等少数表示“需要”的动词后的动名词用主动表被动．e.g.Theroomneedscleaning.Thesechildrenrequirelookingafter.11
