      時(shí)間: 淑航658 分享

        英語(yǔ)是一門(mén)實(shí)用性極強(qiáng)的課程。下面是學(xué)習(xí)啦小編收集整理的人教版初三英語(yǔ)知識(shí)點(diǎn)以供大家學(xué)習(xí)。

        人教版初三英語(yǔ)知識(shí)點(diǎn):被動(dòng)語(yǔ)態(tài)

        被動(dòng)語(yǔ)態(tài)常用于以下兩種情況:

        1.不知道誰(shuí)是動(dòng)作的執(zhí)行者,或者沒(méi)有必要指出誰(shuí)是動(dòng)作的執(zhí)行者;

        2.強(qiáng)調(diào)動(dòng)作的承受者。例如:

        C.熟練轉(zhuǎn)換

        1.將主動(dòng)語(yǔ)態(tài)變被動(dòng)語(yǔ)態(tài)的基本方法為:

       ?、賹⒅鲃?dòng)語(yǔ)態(tài)的賓語(yǔ)作被動(dòng)語(yǔ)態(tài)的主語(yǔ);

       ?、谥^語(yǔ)動(dòng)詞變?yōu)?ldquo;be+及物動(dòng)詞的過(guò)去分詞”,并通過(guò)be的變化來(lái)表達(dá)出不同的時(shí)態(tài);

       ?、壑鲃?dòng)語(yǔ)態(tài)的主語(yǔ)變?yōu)榻樵~by的賓語(yǔ),組成介詞短語(yǔ)放在被動(dòng)結(jié)構(gòu)中的謂語(yǔ)動(dòng)詞之后。(有時(shí)by短語(yǔ)可以省略)。

        2.被動(dòng)語(yǔ)態(tài)的一般疑問(wèn)句是將一個(gè)助動(dòng)詞置于主語(yǔ)之前;否定句是在第一個(gè)助動(dòng)詞后加not;特殊疑問(wèn)句的語(yǔ)序?yàn)椋阂蓡?wèn)詞+一般疑問(wèn)句。例如:

        Where did they grow vegetables?(改為被動(dòng)語(yǔ)態(tài))

        Where were vegetables grown ?

        將主動(dòng)語(yǔ)態(tài)變被動(dòng)語(yǔ)態(tài)應(yīng)注意幾個(gè)特殊情況:

        1.含雙賓語(yǔ)的主動(dòng)結(jié)構(gòu)變?yōu)楸粍?dòng)結(jié)構(gòu)時(shí),有兩種方法:

       ?、賹㈤g接賓語(yǔ)變?yōu)橹髡Z(yǔ),直接賓語(yǔ)保持不變;

       ?、趯⒅苯淤e語(yǔ)變?yōu)橹髡Z(yǔ),間接賓語(yǔ)用介詞to或for引導(dǎo)。

        2.短語(yǔ)動(dòng)詞的被動(dòng)語(yǔ)態(tài):在變?yōu)楸粍?dòng)語(yǔ)態(tài)時(shí),要將短語(yǔ)動(dòng)詞視為一個(gè)整體,其后的介詞或副詞不能省去。

        3.含有復(fù)合賓語(yǔ)的主動(dòng)結(jié)構(gòu)變被動(dòng)結(jié)構(gòu)時(shí),通常將賓語(yǔ)變?yōu)楸粍?dòng)句的主語(yǔ),而賓語(yǔ)補(bǔ)足語(yǔ)就成為主語(yǔ)補(bǔ)足語(yǔ)。注意:省略to的不定式作賓補(bǔ)時(shí),不定式符號(hào)to必須補(bǔ)上。

        4.不定式的被動(dòng)結(jié)構(gòu):動(dòng)詞不定式的被動(dòng)語(yǔ)態(tài)為“to be +過(guò)去分詞”。
