初一下冊英語知識點(diǎn)總結(jié)4
能用作賓語補(bǔ)足語的過去分詞一般都是及物動詞,表示被動意義或已完成意義,有時候兩者兼而有之。作賓語補(bǔ)足語的過去分詞與賓語有邏輯上的動賓關(guān)系,即賓語是過去分詞動作的對象。
She found the door broken in when she came back.她回來時發(fā)現(xiàn)有人破門而人。
My grandfather had his old house rebuilt.我爺爺找人重修了一下他的舊房子。
少數(shù)不及物動詞的過去分詞用作賓補(bǔ)時,強(qiáng)調(diào)動作完成后的狀態(tài).
They found all the guests gone when they woke up.當(dāng)他們醒來時,發(fā)現(xiàn)所有的客人都走了。
動詞-ed形式作賓語補(bǔ)足語的基本用法
動詞的-ed形式可以在“主語+謂語+賓語+賓語補(bǔ)足語”句型中充當(dāng)賓語補(bǔ)足語。在這一結(jié)構(gòu)中,動詞-ed形式和它前面的賓語構(gòu)成邏輯上的被動關(guān)系。如果這種句子改為被動語態(tài),原來的賓語補(bǔ)足語變成了主語補(bǔ)足語。
1. I must get my bike repaired.我必須請人修理自行車。(賓語補(bǔ)足語)
2. The girl was found beaten black and blue.人們發(fā)現(xiàn)那女孩被打得青一塊紫一塊。(主語補(bǔ)足語)
(1)動詞-ed形式可作表示感覺和心理狀態(tài)的動詞的賓語補(bǔ)足語,這類動詞包括see, hear, watch, notice, feel, find, think, suppose, consider等。
We thought the game lost.我們認(rèn)為球賽輸了。
I have never heard him spoken ill of others.我從未聽過有人說他的壞話。
They considered the matter settled.他們認(rèn)為這問題解決了。
(2)動詞-ed形式可作使役動詞的賓語補(bǔ)足語,這類動詞包括make, get, have, keep, leave, hold等。
I have my hair cut once a month.我每個月理一次發(fā)。
He was trying to make himself understood.他正努力使別人聽懂自己。
“have+賓語+done”結(jié)構(gòu)有三個含義：
�、�(請人)把某事做完。She had her house repaired.她請人把屋子修好了。
Where did you have your hair cut?你在哪兒理的發(fā)?
�、谠庥瞿撤N意外情況。He had his hat blown away on his way home.在回家的路上他的帽子被吹掉了。
She had her wallet stolen yesterday.昨天她的錢包被偷了。
�、弁瓿赡呈�(自己也可能參與)。I have had all my spelling mistakes corrected.我把所有的拼寫錯誤都改正了。
He has had one thousand yuan saved this year.他今年已存了1000元。
(3)動詞-ed形式可作表示希望、要求、命令等動詞的賓語補(bǔ)足語，這類動詞包括like，want, wish, expect, order等”這一類動詞的后面作賓語補(bǔ)足語。
He won’t like such questions discussed at the meeting.他不喜歡在會議上討論這樣的問題。
The students wish the TV serial plays continued.學(xué)生們希望電視連續(xù)劇繼續(xù)播下去。
(4)過去分詞用在“with+賓語+賓補(bǔ)”這一結(jié)構(gòu)中,過去分詞與賓語之間是動賓關(guān)系。
The thief was brought in with his hands tied behind his back.小偷被帶進(jìn)來了,雙手被反綁在后面。
初一下冊英語知識點(diǎn)總結(jié)5
1.過去分詞作狀語表示被動或完成，但有些過去分詞(短語)因來源于系表結(jié)構(gòu)，作狀語時不表動作而表狀態(tài)。這樣的過去分詞(短語)常見的有: lost (迷路); seated (坐); absorbed in (全神貫注于); dressed in (穿著); tired of (厭煩)等。如：
Absorbed in deep thought, he didn’t hear the sound.因為沉浸在思考之中,所以他沒聽到那個聲音。
2.過去分詞作狀語來源于狀語從句，在句中一般能作五種狀語，即時間、原因、條件、讓步和方式狀語。如：
Caught in a heavy rain, he was all wet.因為淋了一場大雨，所以他全身濕透了。
(Caught in a heavy rain相當(dāng)于原因狀語從句Because he was caught in a heavy rain)
Grown in rich soil, these seeds can grow fast.如果種在肥沃的土壤里，這些種子能長得很快。
(Grown in rich soil相當(dāng)于條件狀語從句If these seeds are grown in rich soil)
注意：
�、佼�(dāng)從句的主語與主句的主語一致時，才可以把從句的主語省略，且省略掉的主語與其邏輯謂語是被動關(guān)系或如第一段中所講的表示狀態(tài)。
②把狀語從句改為過去分詞作狀語時有時還可保留連詞，構(gòu)成“連詞+過去分詞”結(jié)構(gòu)作狀語，即“while (when, once, until, if, though等連詞)+過去分詞”結(jié)構(gòu)。如：
When given a medical examination, you should keep calm.當(dāng)你做體格檢查時要保持鎮(zhèn)定。
Though beaten by the opposite team, the players didn’t lose heart.
盡管這些球員被對方球隊打敗了，但他們并沒有灰心。

二賓語從句
1賓語從句的學(xué)習(xí)要注意三個方面
第一：語序：在賓語從句中，一律用___________。

XXX幾個特殊的特殊疑問句

What did he do yesterday? I don’t know. ---I don’t know what he did yesterday.
XXX其中 以wh- 疑問詞或how 引導(dǎo)的賓語從句與動詞不定式可相互轉(zhuǎn)換

初一下冊英語知識點(diǎn)總結(jié)13
虛擬，在漢語中表示一種假設(shè)的，不存在的情況，同樣，英語中虛擬語氣是用來表示說話人的主觀愿望或假想，而不表示客觀存在的事實，所說的是一個條件，不一定是事實，或與事實相反。虛擬語氣通過謂語動詞的特殊形式來表示。在初中階段，虛擬語氣一般用于下列情況：
一、條件狀語從句
1、與現(xiàn)在事實相反
若與現(xiàn)在事實相反，虛擬語氣的條件從句的謂語用過去式(be通常用were)，主句謂語用“should(would,could,might)+動詞原形”。如：
IfIwereyou,Iwouldtakeanumbrella.如果我是你，我會帶把傘。(事實上我不可能是你)
IfIknewhernumberIcouldringherup.要是我知道她的電話號碼，我就可以給她打電話了。(事實上我不知道)
2、與過去事實相反
若與過去事實相反，從句：主語+haddone，主句：主語+should/would/could/might+havedone ，例如：
IfI'dleftsooner，I'dhavebeenontime.要是我早點(diǎn)動身，我就準(zhǔn)時到了。(但我動身太遲了)
IfIhadgotthereearlier,Ishould/couldhavemether.如果我早到那兒，我就會見到她。(事實：去晚了)
3、與將來事實相反
從句：①if+主語+weretodo主句：①主語+should/would/could/might+do
�、趇f+主語+did/were②主語+should/would/could/might+do
�、踚f+主語+should+do③主語+should/would/could/might+do
例如：Ifhewent，wouldyougotoo?如果他去，你也去嗎?(大概他不會去)
Ifheshouldcomeheretomorrow,Iwouldtalktohim. 如果他明天來這兒的話，我就跟他談?wù)劇?事實：來的可能性很小)
注意與說明：對于與將來事實相反的情形，請注意以下幾點(diǎn)：
一是這里說的與將來事實相反，實為對將來情況的推測;
二是此用法中的條件從句謂語除用過去式外，有時也用“should+動詞原形”(表示可能性極小，常譯為“萬一”)或“wereto+動詞原形”(表示與將來事實相反的假設(shè));
三是當(dāng)條件從句使用“should+動詞原形”這樣的謂語時，主句謂語除可用“should(would,could,might)+動詞原形”這樣的虛擬語氣外，也可用陳述語氣或祈使語氣。如：
Ishouldseehim,I'lltellhim.萬一我見到他，我就告訴他。
Ifitshouldraintomorrow,don’texpectme.萬一明天下雨，就別等我了。
二、wish后賓語從句
1、表示與現(xiàn)在事實相反的愿望，謂語動詞用過去式。例如：
IwishIhadyourbrains. 我希望我有你那樣的頭腦。(事實：我根本比不上你)
2、表示與過去事實相反的愿望，謂語動詞：had+done 例如：
IwishIhadknownthetruthofthematter. 我希望我那時就知道這件事情的真相。(事實：那時還不知道)
3、表示將來難以實現(xiàn)的愿望，謂語動詞：should/would(情態(tài)動詞)+動詞原形
