湖南省長沙市麓山國際學(xué)校人教版英語九年級英語復(fù)習(xí) 情態(tài)動詞 素材

5/5情態(tài)動詞情態(tài)動詞數(shù)量不多,但用途廣泛,初中考點主要有：can(could),may(might),must,need,shall(should),will(would)。情態(tài)動詞的特征：情態(tài)動詞本身有詞義但不能單獨作謂語,情態(tài)動詞+行為動詞原形一起構(gòu)成謂語。情態(tài)動詞不受主語的人稱和數(shù)的限制,不隨人稱和數(shù)的改變。情態(tài)動詞后可直接+not構(gòu)成否認,可放于句首構(gòu)成一般疑問。1．can和could的用法can(could)表示=1\*GB3①“能力〞、Icanplaytheguitar.=2\*GB3②“許可〞youcangonow.=3\*GB3③“可能性〞Lucymaybehere.等。could為can的過去式。=4\*GB3④表示請求時,could比can更婉轉(zhuǎn)〔屬于現(xiàn)在時態(tài)范圍〕。如：CanIuseyourbike？我可以用你的自行車嗎？[注意]can和could只能用于現(xiàn)在時和過去時兩種時態(tài),將來時中用beableto,beableto所用的時態(tài)比can、could廣。另外can't可表示否認推測“不可能〞。如：That______beMrWang.HehasgonetoBeijing.那肯定不是王老師,他已經(jīng)去北京了。2．may和might的用法may(might)意為=1\*GB3①“可以〞,表示說話人同意、許可或請求對方許可MayIuseyourpen?,=2\*GB3②也可表示祝愿。Maygodblessyou!=3\*GB3③may表允許用于肯定句中Youmaygonow.may的否認式為maynot。might是may的過去式,有兩種用法：一種表示過去式；一種表示虛擬語氣,使語氣更加委婉、客氣,或表示可能性更小。如：______Iuseyourpen?我可以用你的鋼筆嗎？Youmayputonmoreclothes.你可以多穿衣服。Mayyoubehappy.祝你開心。MightIborrowsomemoneynow?我現(xiàn)在可以借點錢嗎？Hemightbealive.他可能還活著。May和might表推測,比擬小的不太有把握的推測。用于肯定句中。Hemaycometomorrow,butI’mnotsure.注意：may構(gòu)成的一般疑問句防止用yes,youmay.以免顯得不客氣。MayIgonow?_Yes,please./Pleasedon’t./否認No,youcan’t.3．must的用法must=1\*GB3①意為“必須,應(yīng)該,一定,準(zhǔn)是〞,表示說話人認為有必要做某事,命令、要求別人做某事以及對事物的推測。must用于一般現(xiàn)在時和一般將來時,過去式可用haveto的過去式代替。如：I______finishmyworktoday.我今天必須完成我的工作。=2\*GB3②否認式mustn’t表“嚴禁、禁止〞含義。Youmustn'tdriveafterdrinking.你絕不能酒后駕車。(1)must和haveto的區(qū)別：must表示說話人的主觀意愿；haveto表示客觀需要haveto的否認形式和疑問式要借助助動詞do。如：Imustdomyhomeworkfirst.我必須首先做家庭作業(yè)。Itisraininghardoutside;I______stayathome.外面雨下得很大,我不得不待在家里。(2)答復(fù)must的提問①肯定答復(fù)：Yes,…must.如：—MustIgohomenow?—Yes,youmust.“我必須現(xiàn)在回家嗎？〞“是的,你必須。〞②否認答復(fù)：No,…needn't./No,…don't/doesn'thaveto.如：—MustIgohomenow？—No,you______________.“我必須現(xiàn)在回家嗎？〞“不,沒必要。〞(3)must可以表示肯定推測,意為“一定〞。比may的可能性大如：Themanmustbeourteacher.那個人一定是我們的老師。4．need的用法(1)need表示“需要,必須〞。主要用于否認句和疑問句中,否認形式為needn‘t,表示“沒有必要,不必〞；need提問時,肯定答復(fù)用must,否認答復(fù)用needn’t。如：—Needwedosomecleaningnow?“我們必須現(xiàn)在大掃除嗎？〞—Yes,youmust.“是的,你們必須。〞—No,youneedn‘t.“不,你們不必。〞(2)need還可當(dāng)做實義動詞使用,這時常用結(jié)構(gòu)為needsth/needtodosth。常用于肯定句中。否認形式和疑問式要借助助動詞do的形式。如：Ineedtolearnmore.我需要學(xué)習(xí)更多。5．shall和should的用法shall用于第一人稱的句子中表示提建議或請求；(建議和請求為考點)should用于各種人稱的句子中強調(diào)義務(wù)或責(zé)任“應(yīng)該〞。如：______wegooutforawalk?我們出去散步好嗎？(建議)Youshouldstudyhardatschool.你們在學(xué)校應(yīng)該努力學(xué)習(xí)。(勸告)6．will和would的用法Will=1\*GB3①情態(tài)動詞,用于第二人稱疑問句時,表示征求意見或提建議。=2\*GB3②助動詞構(gòu)成一般將來時。would為will的過去式,可用于多種人稱,=1\*GB3①表示意愿。如：Willyouhavealittlesoup?你要不要喝點湯？=2\*GB3②wouldyoulikesth/todosth?提出建議與請求。此外還有情態(tài)動詞：hadbetter,oughtto,haveto等等。[歸納]情態(tài)動詞表推測的用法(1)肯定句中一般用must(一定),may(可能),might/could(也許,或許),其中must表推測的語氣最強,其余依次漸弱。如：Thebookmustbehers.Hernameisonit.這本書一定是她的,她的名字在上面。Hemustberunning.他一定是在跑步。Theymayknowthewaytothelibrary.他們可能知道去圖書館的路。(2)否認句中一般用can't/couldn't(不可能)。如：Thatmancan‘tbeMrLibecausehehasgonetoLondon.那個人不可能是李老師,因為他去倫敦了。(3)疑問句中用can/could(能)。如：—CantheredsweaterbeTom's?—No,itcan't.Hecan'tstandred.“這件紅毛衣會是吉姆的嗎？〞“不,不可能。他不能忍受紅色。〞[注意]might,could并不是may,can的過去式,而是表示語氣較委婉或可能性較小。=4\*GB2⑷情態(tài)動詞+一般現(xiàn)在時/do表示對現(xiàn)在發(fā)生的事情的推測。如：Whosebookisthis?ItmustbelongtoLucy.它一定屬于露西的。情態(tài)動詞+進行時/bedoing表示對現(xiàn)在正在發(fā)生的事情的推測。如：Hemustbesleepingnow.現(xiàn)在他一定正在睡覺。情態(tài)動詞+完成時havedone表示對已經(jīng)〔過去〕發(fā)生的事情的推測。如：Ourclassroomisveryclean.Itmusthavebeencleanedyesterday.昨天它一定被清掃了。〔〕1.We_________usemobilephonewhentheplanetakeoff.maynotB.shouldn’tC.needn’tD.mustn’t〔〕2.--Excuseme.Canyoutellmewhattimeitisnow?--Sorry,I______.Mywatchdoesn’twork.A.can’tB.maynotC.mustn’tD.needn’t〔〕3.—IsthatKate’scar?—It_____behers.Shehasjustgoneforameeting.A.can’tB.shouldC.mustn’tD.may〔〕4.—Let’sgoclimbing,shallwe?—You______bejoking!Don’tyouknowI’mafraidofhighplaces?A.mayB.canC.mustD.should〔〕5.We______paytogetintotheconcert.It'sfree.
