I’vebeensittinginthegarden.

I’dbeenworkingforsometimewhenhecalled.

语态

可以有两种被动结构的类型,例如:

Hewassaidtobejealousofhersuccess.

Itwassaidthathewasjealousofhersuccess.

能同时适用于上述两个句型的主动词通常都是表示“估计”,“相信”等意义的动词,常见的有assume,believe,expect,fear,feel,know,presume,report,say,suppose,understand等.

Itissupposedthattheshiphasbeensunk.

Theshipissupposedtohavebeensunk.

担当besupposedto与不定式的一般形式搭配时往往表示不同的意义.例如:

Whyareyoudrivingsofastinthisarea?Youaresupposedtoknowthespeedtoknowthespeedlimit.(你应该晓得速度限制)

双宾语及宾补结构的被动语态

双宾语结构的被动语态:双宾语结构变为被动语态时,可以把主动结构中的一个宾语变为主语,另一个宾语仍然保留在谓语后面,但多数是把间接宾语变为主语.

Hewasaskedanumberofquestionsatthepressconference.

Twodayswereallowedthemformakingthenecessarypreparations.

宾补结构的被动语态:

ShewascalledBigSisterbyeverybody.

Thenhewasmadeasquadleader.

Hewasconsideredquitequalifiedforthejob.

Theroomwasalwayskeptcleanandtidy.
