本身有各種意義,但不能單獨作謂語,只能和主要動詞共同構(gòu)成謂語,表示說話人的語氣和情態(tài),這類動詞叫情態(tài)動詞。情態(tài)動詞沒有人稱和數(shù)的變化。其否定形式一般是在其后加not，一般疑問句通常將其提到句首。二、表示推測

除表示語氣外，部分情態(tài)動詞還可以表示推測四、情態(tài)動詞情態(tài)動詞及用法對比：

情態(tài)動詞基本用法表示推測can能，會，可以可能can’t不會，不能不可能must必須，一定肯定musn’t一定不要，禁止may/might可以可能可能性大小：

情態(tài)動詞基本用法例句should“應(yīng)該”，表示要求或命令，也可以表示勸告或建議We

should

keep

the

air

fresh.shouldn’t“不應(yīng)該”We

shouldn’t

waste

water.will“愿意”表示詢問、請求，用于疑問句中，常用于第二人稱Willyoupassmethebook？would“愿意”表示自愿做或主動提出做某事，如：意志、愿望或決心等Jane

said

she

would

not

go

with

Tom,

for

she

didn’t

like

him.其他的情態(tài)動詞及用法:一、英語動詞有主動語態(tài)和被動語態(tài)這兩種語態(tài)主動語態(tài)表示主語是動作的執(zhí)行者

被動語態(tài)表示主語是動作的承受者二、結(jié)構(gòu):主語+be+及物動詞的過去分詞+其他1.一般現(xiàn)在時的被動語態(tài)：am/is/are+done被做某事2.一般過去時的被動語態(tài)：was/were+done被做了某事3.一般將來時的被動語態(tài)：will（not）+be+done將(不)會被做某事4.含有情態(tài)動詞的被動語態(tài)：should/must+be+done應(yīng)該/必須被做某事

shouldn’t/mustn’t+be+done不應(yīng)該/禁止被做某事五、被動語態(tài)被動語態(tài)表示主語是謂語動作的承受者，被動語態(tài)由“be+V-ed”構(gòu)成。be隨著主語人稱和數(shù)以及時態(tài)的不同而變化。ItwasmadeinGermanyin1681.

它于1681年在德國制造。

1.不知道或沒必要指出動作的執(zhí)行者。Chineseisspokenbymoreandmorepeopleintheworld.世界上越來越多的人說中文了。2.強調(diào)動作的承受者。

被動語態(tài)3.動作的執(zhí)行者有較長的修飾語。Theplanwassupported

by

thosewhowishedtohavemorechancestospeakEnglish.

該計劃得到了那些希望有更多機會講英語的人的支持。4.出于禮貌，不愿意說出動作執(zhí)行者。1)Youarerequestedtoattendthemeeting.請你參加會議。2)Iwastoldthatyouwerenothonestenough.有人告訴我你不夠誠實。

三、主動語態(tài)變被動語態(tài)的注意事項小口訣：

賓變主，主變by+賓，謂語動詞用被動（be+done）,其他成分不變。被動語態(tài)表示主語是謂語動作的承受者謂語動詞be(not)+done(V-ed)被動語態(tài)肯定句：主語+be+V-ed(+by…).否定句：主語+be+not+V-ed(+by…).一般疑問句：Be+主語+V-ed(+by…)?特殊疑問句：疑問詞+be+主語+V-ed(+by…)?結(jié)構(gòu)

定義構(gòu)成時態(tài)主動語態(tài)一般現(xiàn)在時do/does一般過去時did一般將來時will/shall/begoingto+do現(xiàn)在完成時have/hasdone現(xiàn)在進行時am/is/aredoing過去進行時was/weredoing被動語態(tài)am/is/are+donewas/were+donewill/shall/begoingto+be+donehave/has+beendoneam/is/are+beingdonewas/were+beingdone

練：Finally,thepoliceofficercaughtthethief.(改為被動語態(tài))Finally,thethief________________bythepoliceofficer.wascaught四、易錯點：

主動語態(tài)中有些感官動詞（如hear,see,watch,notice等）和使役動詞（如make,let等）后用不帶to的不定式作賓語補足語，變?yōu)楸粍诱Z態(tài)時，要把不定式符號to還原。hear/see
