Itmusthaverainedlastnight,forthegroundiswet.

Youmusthavebeenmadtospeaktotheservant.

二、“can/could+have+過去分詞”表示對過去某種情況的懷疑或不確定。can和could一般用于否定句和疑問句，could的語氣較can弱。如：

Ididn'tseeheratthemeetingthismorning;shecan't/couldn'thavespokenatthemeeting.

Hecan'thavefinishedtheworksosoon.

三、“may/might+have+過去分詞”表示對已發(fā)生的動作或存在的狀態(tài)進行不肯定的推測，might的語氣比may弱一點。這種結構主要用于肯定句和否定句，疑問句改用can或could。如：

Theymaynothaveknownitbeforehand.

Youmighthavereadaboutitinthepapers.

四、“need+have+過去分詞”表示過去做了不必做或不需要做的事情，或過去做某事純屬多余。如：

Needtheyhavedoneitlastweek?

Ineedn'thaveboughtsomuchwine—onlyfivepeoplecame.

五、“should/oughtto+have+過去分詞”表示過去本該做某事但沒做，其否定式表示過去不該做某事但做了，這種句式含有不滿或責備之意，oughtto的語氣比should強一些。如：

Yououghtto/shouldhavestudiedharder.你本應該更努力學習的。（但沒有）

Heoughtn'tto/shouldn'thavedonethat.他本來就不該做那件事。（可是做了）

六、“would＋have＋過去分詞”表示對過去的某種情況進行猜測，或本來要做某事卻因某種原因未做成，通常用來說明某一情況，但不像用should或oughtto那樣含有責備之意。如：

Iguessthepoetwouldhavebeenabouttwentywhenshewroteherfirstpoem.
