asyoutellme

areinteresting.ThisisthesamebookasIlentyouyesterday.4.as代表前面主句意思時，有“正如…〞之意，而which沒有此意思，從句中的動詞常是expect,know,see,think,want,suppose等。Hewonthematch,aswehadexpected.Heagreedtotheplan,aswastobeexpected.Thepolicewerelookingforhim,ashethought.考點二：as與which引導(dǎo)的定語從句Hereissobigastoneasnomancanlift.編輯課件5.as在從句中作主語時，后面常接行為動詞的被動語態(tài)，如beknown，besaid，bereported等，如從句中行為動詞是主動語態(tài)，一般要用which作主語。e.g.Shehasbeenlateagain,aswasexpected.Tomhasmadegreatprogress,whichmadeushappy.6.如果從句的內(nèi)容對主句內(nèi)容起著消極作用，或者說導(dǎo)致的結(jié)果，那么用which.a.Hecheatedhisfriendofmachmoney,whichwasverydisgraceful.b.Hecamebacklate,whichmadehismotherworried.考點二：as與which引導(dǎo)的定語從句編輯課件考點三：關(guān)系代詞前介詞確實定如何選定介詞:1.根據(jù)從句中動詞與先行詞的邏輯關(guān)系，請體會：e.g.Isthatthenewspaper

that(that/which)that/whichthat解題點撥：that引導(dǎo)的定語從句是對其先行詞的修飾或限制；在句中作成份(作賓語省略),指物時可用which代替；而同位語從句是對前面名詞的說明和解釋。that在從句中僅起連接作用,不充當成份，不能省略,不能用which代替。

way后面的定語從句的引導(dǎo)詞有inwhichthat或不填，如：

Irecognizedhe’sfromAustraliafromtheway__________________hespeaks.inwhich(that/不填)編輯課件注意二：定語從句的位置問題一般的說，定語從句由關(guān)系詞引導(dǎo)緊跟在被修飾的詞〔先行詞〕后邊。As引導(dǎo)的定語從句可以放在句首。Ihappenedtomeetthemaninthestreet.

A.whomyouoncespokeB.towhoyouoncespoke

C.youoncespoketohimD.youoncespoketo

編輯課件注意二：定語從句的位置問題.Ihappenedtomeetthemaninthestreet.

A.whomyouoncespokeB.towhoyouoncespoke

C.youoncespoketohimD.youoncespoketo

但是如果在容易造成歧義的情況下可以的。如果把定語從句放在inthestreet之前，容易被人理解為“你曾經(jīng)在街上說過話的人〞。所以先要照顧句子意思編輯課件注意二：定語從句的位置問題但是如果在容易造成歧義的情況下可以的。如果把定語從句放在inthestreet之前，容易被人理解為“你曾經(jīng)在街上說過話的人〞。所以先要照顧句子意思，另如：
