Unit4AttitudestowardsOurElders-grammar學(xué)案

Unit4AttitudestowardsOurElders-grammar學(xué)案

省略

一概述省略是一種修辭,它的使用主要是為了避免重復(fù),它不僅適用于書面語,而且在口語中更加明顯.

1概念為了表達(dá)簡潔,或重點(diǎn)突出,常省去某個詞,短語,甚至句子.這種形式就叫省略.

HesaidthathewouldpayavisittotheGreatWallthenextweek.

Heisonlyaliveandishealthy.

當(dāng)在英語中也有許多的固定省略結(jié)構(gòu),這種省略其實(shí)是一種約定的歷史文化,我們不需將其補(bǔ)充完整,即使按照語法可以這樣做,也沒有必要.如:

Nopains,nogains

Seeingisbelieving

Outofsight,outofmind

2省略的目的和遵循的原則

省略有兩個目的

1語言簡潔,結(jié)構(gòu)緊湊.

Iwonderwhenandwheretoholdthemeeting

when=whentoholdthemeeting

---Illgiveyouanecklaceasabirthdaygift

---Really?butwhen?when=whenyouwillgiveittome

2重點(diǎn)突出,目標(biāo)明確

Willyoutellmebywhomandforwhomitwasordered?

bywhom=itwasorderedbywhom

---Whowillbesenttocarryouttheplan?

---Johnson

它遵循的原則是不破壞結(jié)構(gòu)或引起歧義

TheyvisitingandwewillbevisitingtheHeavenTemple

應(yīng)改為TheyareandwewillbevisitingtheHeavenTemple

二省略句的應(yīng)用

一簡單句中的省略

1主語的省略

1第一人稱省略

Ihopetoseeyouagain

2第二人稱在祈使句中的省略

Goandseewhoitis

Dontopenthewidow,oryoumaycatchacold

3第三人稱的省略

SheDoesntlookwell

ItisaPityhewonthelp

2動詞的省略

1助動詞省略,多在口語中

Hi,Tom,whereyougoing?

2主動詞省略.

MarydoesntspeakFrench,butJimdoes.

TomcanspeakEnglish,andsocanLucy.

---Jimhaspassedtheexam

---Sohehasandsohaveyou

3系動詞省略

Areyouhungry?

4Therebe句型的省略

Thereoughttobenobodyintheclassroom

IsthereAnythingIcandoforyou?

5在獨(dú)立主格結(jié)構(gòu)中being;havingbeen的省略,一般只適用于其后是介詞或短語,如果是名詞不省略

Themeetingbeingover,theywenthome

Bookbeinginhand,heenteredtheroom.

Itbeingsunday,wedidtgotoschool.

6不定式to后動詞的省略。這類動詞有expect,like,wish,hope,prefer;love;intend,mean,refuse等

----Wouldyouliketoattendtheparty?

----Idliketo

另外，在haveto;needtooughtto;begoingto;usedto后也省略主動詞

Idontliketostayuplate,butIusedto

Idontwanttomeettheman,butIhadto二從句中的省略

1定語從句中的省略

1作賓語的關(guān)系代詞which;that;whom的省略

DoyouknowthegirlwhomItalkedtojustnow?

Haveyouseenthebikewhich/thatIboughtfromTom?

如果定語從句中的動詞后的介詞，放到關(guān)系代詞前，那么關(guān)系代詞不能省略。

2作狀語的關(guān)系副詞when/where/why的省略

ThatwasthelasttimewhenImethim

2狀語從句中的省略

當(dāng)狀語從句中的主語和主句的主語一致時(shí)，可以省略狀語從句中的主語和系動詞be.

1連詞when;if;evenif;unless;once;until;as;than+pp

Hedidtheworkaswellasexpected

Iwontattendthepartyevenifinvited

2連詞〈when;while;though+doing

Icameacrosshimwhencrossingonthestreet.

Thoughworkinginsuchpoorconditions,hestillfinishedtheworkontime.

3連詞as,asif,once+名詞

Onceathief,heworksasapolicemannow.

4連詞though,whether,when,if+形容詞

Ifnecessary,pleaseapologizetoher

5連詞,while,asif,whether+介詞短語

WhileinEngland,helearnedaforeignlanguage.

另外，我們也可以用so;not替代上文中的內(nèi)容，此時(shí)常用ifso/not

Workhardaroundtheclock.Ifso,youwillsucceed.

Youshouldfinishtheworkontime.Ifnot,youwillbepunished

在某些形容詞glad;ready;pleased;happy等后。

---Willyoucarryouttheplan?

---Imgladto

假如語境中有表示時(shí)態(tài)的have,havebeen,和be，常在答句中表現(xiàn)出來。

---whyhaventyouattendedthelecture?

---Idliketohave,butitrainedheavily

9．Casiftosee是asifhewasgoingtosee的活力說法。
