初中英語 被動(dòng)語態(tài)復(fù)習(xí)課件

第21講:被動(dòng)語態(tài)之用法歸納語態(tài)是動(dòng)詞的一種形式,表示句子中主語和謂語動(dòng)詞的關(guān)系,主動(dòng)語態(tài)表示主語是動(dòng)作的執(zhí)行者,被動(dòng)語態(tài)表示主語是動(dòng)作的承受者。只有及物動(dòng)詞才能用于被動(dòng)語態(tài)。

一．被動(dòng)語態(tài)的時(shí)態(tài)：

1.一般現(xiàn)在時(shí)的被動(dòng)語態(tài)：

am/is/are+動(dòng)詞的過去分詞

2.一般過去時(shí)的被動(dòng)語態(tài)：

was/were+動(dòng)詞的過去分詞

3.一般將來時(shí)的被動(dòng)語態(tài)：

willbe+動(dòng)詞的過去分詞

4.現(xiàn)在進(jìn)行時(shí)的被動(dòng)語態(tài)：

am/is/are+being+動(dòng)詞的過去分詞

5.現(xiàn)在完成時(shí)的被動(dòng)語態(tài)：

have/has+been+動(dòng)詞的過去分詞

6.情態(tài)動(dòng)詞的被動(dòng)語態(tài)：

情態(tài)動(dòng)詞+be+動(dòng)詞的過去分詞

二．被動(dòng)語態(tài)的基本用法:

(1)需要強(qiáng)調(diào)動(dòng)作的承受者時(shí)

TheGreatWallisenjoyedbymillionsofpeopleallovertheworld

Englishiswidelyspokenintheworldnow.

(2)不知道或沒必要指出動(dòng)作的執(zhí)行者時(shí)

Mr.Wangisinvitedtothemeetingtoday.

Theproblemisdealtwithnow.

(3)當(dāng)說話人需要強(qiáng)調(diào)客觀時(shí)

Itissaidthatshewasabeautywhenshewasyoung.

三．主動(dòng)主動(dòng)語態(tài)變被動(dòng)語態(tài)的變法：

口訣：賓變主，主變賓，謂變bedone,時(shí)不變，數(shù)格必須隨被變。

注：1.主動(dòng)、被動(dòng)的時(shí)態(tài)要一致。

2.主動(dòng)、被動(dòng)的句式要一致。

3.變成的被動(dòng)語態(tài)的主語與謂語在單復(fù)數(shù)上保持一致。

語態(tài)轉(zhuǎn)換不被動(dòng)語態(tài)的步驟

1,把原主動(dòng)句中的賓語轉(zhuǎn)換為被動(dòng)語態(tài)的主語

2,把動(dòng)詞改為被動(dòng)語態(tài)形式即"be+過去分詞"。

3,原來主動(dòng)語態(tài)句子中的主語,如果需要就放在by的后面以它的賓格形式出現(xiàn)(因?yàn)閎y是介詞,后面需跟賓格作介詞的賓語。)以指明做事的人或物,如果沒有必要,可以省略。

4,其它成分不變

5,被動(dòng)語態(tài)中"by+賓語"的省略

被動(dòng)語態(tài)句式中的"by+賓語"表示及物動(dòng)詞所表示動(dòng)作的執(zhí)行者,但是在遇到以下情況時(shí),表示動(dòng)作執(zhí)行者"by+賓語"常常被省略。

(1)動(dòng)作執(zhí)行者不確定時(shí)

Paperismadefromwood.

Manypeoplearekilledintrafficaccidentseveryyear.

(2)不必表明動(dòng)作執(zhí)行者時(shí)

Englishisalsospokenasthesecondlanguageaswellasoneoftheofficiallanguages

Footballisplayedinmostschools。

(3)動(dòng)作執(zhí)行者為一般大眾時(shí)

BothEnglishandSpanisharespokeninthisarea.

一般過去時(shí)的被動(dòng)語態(tài)的基本句式

(1)肯定式:主語+was/were+過去分詞+by

ItwasmadeinBeijingRen'aiEducationInstitute.

(2)否定式:主語+was/were+not+過去分詞+by

Shewasnotgivenapanitingbyhim.

Thisquestionwasnotdiscussedatthemeetingyesterday.

(3)一般疑問句:Was/Were+主語+過去分詞+by?

Wasitmadeofbamboo?

(4)特殊疑問句:特殊疑問詞+was/were+過去分詞+by

Whatwasismadeof?

教你一招

如果句子為一般現(xiàn)在時(shí),主動(dòng)語態(tài)用do/does,被動(dòng)語態(tài)用is/am/are

如果句子為一般過去時(shí),主動(dòng)語態(tài)用did,被動(dòng)語態(tài)用was/were.

由情態(tài)動(dòng)詞構(gòu)成的被動(dòng)語態(tài)的基本句式

(1)肯定式:主語+情態(tài)動(dòng)詞+be+過去-Watercanbechangedintoice.

Sheoughttotidyupherbedroom----Herbedroomoughttobetidiedup.

Youshouldbuyadictionaryatonce----Adictionaryshouldbeboughtatoncebyyou.

(2)否定式:主語+情態(tài)動(dòng)詞+not+be+過去分詞+by

Youmustnottakeoutanybooks.-Anybooksmustn'tbetakenoutbyyou.

Theyneedn'tlookafterthelittlechild----Thelittlechildneedn'tbelookedafter(bythem)

(3)疑問句:情態(tài)動(dòng)詞+主語+be+過去分詞+by

Canyouuseit?------Canitbeused?

常見的情態(tài)動(dòng)詞有:can,may,oughtto,must,dare,need,should.

主動(dòng)語態(tài)不能變?yōu)楸粍?dòng)語態(tài)的情況:

1,當(dāng)賓語是反身代詞時(shí)ThemanintroducedhimselfasMr.Parker.

2,當(dāng)謂語是表示狀態(tài)的及物動(dòng)詞時(shí)Doesthepairofnewshoessuityou?

Wewillhaveameeting.

四．特殊情況的被動(dòng)語態(tài)：

1.帶雙賓語的被動(dòng)語態(tài)：

動(dòng)詞+sb(間賓)+sth(直賓)

口訣：如遇雙賓語，一般變間賓，若把直賓變，to/for間賓連。

1).give/pass/show與介詞to搭配。

givesbsth——sb+begivensth或sth+begiven+tosb.

2).buy/make/cook與介詞for搭配。

buysbsth——sb+bebought+sth或sth+bebought+forsb

Hegavemeabook

I____________abookbyhim.

Abook_____________mebyhim.

Mymothermademeacake.

I_________acakebymymother

Acake____________mebymymother.

2.帶省to的不定式作賓補(bǔ)的被動(dòng)語態(tài)：動(dòng)詞+sb+dosth.

口訣：感使動(dòng)詞真叫怪，to來to去記心懷，主動(dòng)語態(tài)to離去被動(dòng)語態(tài)to回來。

動(dòng)詞：make/let/have/see/hear/feel/watch

makesbdosth----sb+be+made+todosth

Thebossmadetheworkersworkallday

Theworkers____________workalldaybytheboss.

3.see/hear/notice/keep+sb+doingsth句型中變被動(dòng)語態(tài)時(shí)doing不變。

IheardTomsingingjustnow

Tom_______________bymejustnow.

4.以動(dòng)詞短語作謂語的主動(dòng)語態(tài)變被動(dòng)語態(tài)時(shí)，不可丟掉后面的介詞或副詞。

Weshouldtakecareoftheold.

Theoldshould_____________________.

五．注意事項(xiàng)：

1.有些及物動(dòng)詞或動(dòng)詞短語不能用于被動(dòng)語態(tài)：

last,have,own…..belongto,suit…fine,

2.不及物動(dòng)詞是沒有被動(dòng)語態(tài)：

happen,takeplace,appear,hold(容納)

3.系動(dòng)詞是沒有被動(dòng)語態(tài)：Look,feel,sound,smell,taste….

Thedishtastesgood.

4.有些詞組沒有被動(dòng)語態(tài)：sellwell,writewell,ridewell,drivewell

Thiskindofskirtsellswell.

5.need表示需要時(shí)，后面常接doing形式表示被動(dòng)意義，相當(dāng)于tobedone.

Allthecomputersneedrepairing.=

Allthecomputersneed_______________.

6.在too…to…及enoughto…結(jié)構(gòu)中有時(shí)表示被動(dòng)意義。

Theproblemistoodifficulttosolve.第21講:被動(dòng)語態(tài)之重要考點(diǎn)■將語態(tài)與主謂一致結(jié)合起來命題

1.Alltheemployeesexceptthemanager______toworkonlineathome.

A.encourages

B.encourage

C.isencouraged

D.areencouraged

解析：主語是alltheemployees(復(fù)數(shù))，而不是themanager，排除答案A和C；又因alltheemployees與encourage是被動(dòng)關(guān)系，要用被動(dòng)語態(tài)，排除B，故選D。

2.Alibrarywithfivethousandbooks_______tothenationasagift.

A.isoffered

B.hasoffered

C.areoffered

D.haveoffered

解析：alibrary是offer的承受者，要用被動(dòng)語態(tài)，排除B和D；又因主語(library)是單數(shù)，排除C；故選A。注意：withfivethousandbooks是alibrary是定語。

■將語態(tài)與虛擬語氣結(jié)合起來命題

—Don’tyouthinkitnecessarythathe______toMiamibuttoNewYork?

—Iagree,buttheproblemis______hehasrefusedto.

A.willnotbesent;that

B.notbesent;that

C.shouldnotbesent;what

D.shouldnotsend;what

解析：因he與send是被動(dòng)關(guān)系，排除D；又因it(is)necessary后的that從句的謂語要用“(should+)動(dòng)詞原形”，排除選項(xiàng)A；答句中的表語從句不缺任何句子成分，用that；故選B。

■將語態(tài)與倒裝結(jié)合起來命題

Onlyaftermyfriendcame______.

A.didthecomputerrepaired

B.berepairedthecomputer

C.wasthecomputerrepaired

D.thecomputerwasrepaired

解析：因thecomputer與repair是被動(dòng)關(guān)系，排除A；又因only加狀語置于句首，要用部分倒裝，排除選項(xiàng)D和B；故選C。

■將固定短語中的名詞作主語來增加句子理解難度

Goodcaremust______babies,particularlywhiletheyareill.

A.take

B.takeof

C.betaken

D.betakenof

解析：由固定短語takegoodcareof(好好照看)是可知，goodcare與take是被動(dòng)關(guān)系，排除A和B；選項(xiàng)C中又漏掉了of；故選D。

■在語境中將語態(tài)與時(shí)態(tài)結(jié)合起來命題

1.Thenumberofdeathsfromheartdiseasewillbereducedgreatlyifpeople______toeatmorefruitandvegetables.

A.persuade

B.willpersuade

C.bepersuaded

D.arepersuaded

解析：因people與persuade是被動(dòng)關(guān)系，排除A和B。又因?yàn)橹髡Z是一般將來時(shí)，條件句中用一般現(xiàn)在時(shí)，所以選D。

2.Hundredsofjobs______ifthefactorycloses.

A.lose

B.willbelost

C.arelost

D.willlost

解析：因lose與jobs是被動(dòng)關(guān)系，排除A和D；又因條件狀語從句是一般現(xiàn)在時(shí)，主句中的謂語動(dòng)詞應(yīng)當(dāng)是一般將來時(shí)，故選B。

3.Withmoreforestsbeingdestroyed,hugequantitiesofgoodearth______eachyear.

A.werewashedaway

B.isbeingwashedaway

C.arewashingaway

D.arebeingwashedaway

解析：因goodearth(沃土)與washaway(沖走)是被動(dòng)關(guān)系，排除C；又因quantitiesof…作主語，謂語動(dòng)詞用復(fù)數(shù)，排除B；指近階段(近些年)正在發(fā)生的事，用現(xiàn)在進(jìn)行時(shí)，排除A；故選D。

4.—Thewindowisdirty.—Iknow.It______forweeks

A.hasn’tcleaned

B.didn’tclean

C.wasn’tcleaned

D.hasn’tbeencleaned

解析：由is和forweeks可知，要用現(xiàn)在完成時(shí)態(tài)，排除B和C；又因It(Thewindow)與clean是被動(dòng)關(guān)系，要用被動(dòng)語態(tài)，所以選D。

5.—GeorgeandLucygotmarriedlastweek.Didyougotothewedding?

—No,I______.Didtheyhaveabigwedding?

A.wasnotinvited

B.havenotbeeninvited

C.hadn’tbeeninvited

D.didn’tinvite第21講:被動(dòng)語態(tài)之專項(xiàng)練習(xí)被動(dòng)語態(tài)專項(xiàng)練習(xí)共分兩大部分，第一部分適合初中學(xué)生練習(xí)，第二部分是專門供高中生使用的。
