态不能与表示一段时间的状语连用。若要表达相应的意思,则要改换动词或时态。Theworkwasfinishedtwoweeksago.这项工作在两周前已经完成。Theworkhasbeenfinished.这项工作已经完成。栏目导航栏目导航153
.动词短语动词短语是一个不可分割的整体,在被动语态中要保持完整性,其中的介词或副词不可省略。Itissaidthattheproblemhasbeenlookedinto.据说已经调查了这个问题。栏目导航栏目导航164.带有复合宾语的动词变为被动语态时,只能将宾语变为主语,原来的宾补改为主语补足
语。注意:原来作宾补的省略to的不定式在被动语态中要用带to的不定式。Ihavetoldthemtohelpyou.→Theyhavebeentoldtohelpyou.栏目导航栏目导航175.带有双宾语的动词如give,send,bring,take,teach,show,t
ell,make,sing,write,read,sell,buy,pay,lend,pass,promise等,变为被动语态时,一般将间接宾语变为被动语态的主语,若将直接宾语变为被动语态的主语时,间接宾语前面要
用相应的介词。栏目导航栏目导航18Thecompanyhasgivenhimachancetoworkabroadrecently.→Hehasbeengivenachancetoworkabroadrecently(bythecompany).→Achance
