高三英語語法知識點總結(jié)1
虛擬語氣在一些特殊詞中的使用或含蓄條件句
1.wish后的賓語從句。
與現(xiàn)在愿望不一致，用主語十過去時，例如：
I wi。hIwere you.
與過去愿望不一致，用主語+had+過去分詞，例如：Iwish I had visited the White House whenI was in the States與將來愿望不一致，用主語+would (could)+原形。
2.It's time句型：當lt's tine后用that從句時應該為主i吾+should+動詞原形或主語十過去時，例如：It，s time thatyou went to school.或It's time that you should go to schooL
3- If only引起的感嘆句相當于“How I wish+賓語從句”。
(l)If only he could come.他要能來就好了。
(2)If only I had known the answer.我要早知道答案就好了。
4.WOuld rather，as if(though)引導的從句也需使用虛擬語氣，表示過去的情況用過去完成時，表示現(xiàn)在與將來的情況用過去時，例如：
(l)I'd rather you posted the letter right away.
(2)She loves the children as if they were hers.
5.含蓄虛擬條件句含蓄條件句是指句中沒有明顯的虛擬條件句，而是利用其他手段來暗示存在虛擬條件。但是這類隱含式虛擬條件句往往都可以轉(zhuǎn)化為if引導的條件句。常用來表示含蓄虛擬條件的手段有：
(1)介詞或介詞短語。如but for，but that，without,in case of, under more favorable condition等。
(2)連詞。如so that, unless, in case, supposing,lest, provided(倘若……)，for fear that(唯恐)，in orderthat, on condition that, if only(要是……就好了)等。
注意：lest, for fear that和in case引起的從句中謂語動詞多用should+動詞原形，但也可以不用虛擬語氣，而用動詞的陳述語氣形式。例如：The foreign teacher spokeslowly in case we misunderstood him這位外籍教師說得很慢以免我們誤解。
(3)通過上下文及內(nèi)在含義，句中往往有but,otherwise, unfortunately等類似轉(zhuǎn)折詞。
without, but. but for, otherwise引起的短語或句子常暗含著含蓄條件。例如：
①Without you,1 would never know him
②But for your oooperation, we wouldn't have done it
③But that she was afraid, she would have said no. .
④i would be most glad to help you, butI am busy now.
⑤I would have come to the party yesterday, but ljwas working.
⑥I am busy now, otherwise l would do you the favor!
現(xiàn)在完成時
1、 現(xiàn)在完成時的概念：現(xiàn)在完成時表示動作發(fā)生在過去，其結(jié)果對現(xiàn)在有影響。 例：Tom has gone out (go的動作發(fā)生在過去，對現(xiàn)在有影響)
2、 延續(xù)性動詞可以和表示一段時間的時間狀語連用;非延續(xù)性動詞則不可以。 例：正確說法：The train has been in the station for two hours;
錯誤說法：The train has stopped in the station for two hours.
(這輛火車進站停了兩個小時)
延續(xù)性動詞 非延期性動詞
定義 動作有持續(xù)性，可以持續(xù)一段時間。如：live(居住)就可live一年兩年。 運作在短時間內(nèi)結(jié)束，不能延續(xù)。如marry(結(jié)婚)就不能marry一年兩年。
例詞 Listen,play,rain,work Arrive,begin,borrow,finish
3、現(xiàn)在完成時的構成：
(1)have(has)+過去分詞：Tom has gone out。
(2)現(xiàn)在完成時的否定和疑問形式：否定形式在have、has后加not;疑問形式將Have、has提前，如Has Tom gone out。
(3)過去分詞的概念及其變化形式：
概念：它和現(xiàn)在進行時中的“動詞的ing形式”一樣，只是英語中表達時態(tài)的一種固定形式。
變化形式：大多數(shù)動詞的過去分詞的外形和動詞的過去式完全一樣。只有那些不規(guī)則變化的動詞，不運詞的過去式不一樣。具體參照“不規(guī)則動詞表”。

英語中過去分詞可作賓補，(此時的過去分詞一般是及物動詞)表被動意義或完成意義，有時兩者兼而有之。做賓補的過去分詞與賓語有邏輯上的動賓關系，即賓語是過去分詞動作的對象。如：
She found the door broken in when she came back.(賓補與賓語有被動的關系，表一種狀態(tài)。)
一. 過去分詞用在表狀態(tài)的動詞keep,leave等的后面。
Eg:They kept the door locked for a long time.
Keep your mouth shut and your eyes open.(諺語：少說多看)
Don't leave such an important thing undone.
Don't leave the windows broken like this all the time.
二.過分詞用在get,have,make, 的后面。
1.注意“have +賓語+過去分詞”的兩種情況：
A)表"讓某人做某事/讓某事(被人)做"
eg: I have had my bike repaired.
The villagers had many trees planted just then.
B)表"遭遇到某種不幸，受到打擊/受....影響，蒙受..... 損失"
Eg:I had my wallet stolen on a bus last month.
The old man had his leg broken in the accident.
He had his leg broken in the match yesterday.(MET1986)
2."make+賓語+過去分詞",在這種結(jié)構中，過去分詞的動詞必須是表示結(jié)果含義的。如：
They managed to make themselves understood in very simple English.
I raised my voice to make myself heard.
三、過去分詞用在感觀動詞watch,notice,see,hear,listen to ,feel,find等后面。如
When we got to school,we saw the door locked.
We can hear the windows beaten by the heavy rain drops.
He felt himself cheated.
The managers discussed the plan that they would like to see carried out the next year.(NMET2000)
四、過去分詞用在want,wish,like ,expect等表示“希望，愿望”這一類動詞后面做賓補。如
The boss wouldn't like the problem discussed at the moment.
I would like my house painted white.
I want the suit made to his own measure.
I wish the problem settled.
五、過去分詞用在“with +賓語+賓補”這一結(jié)構中，過去分詞與賓語之間是動賓關系。如：
The thief was brought in with his hands tied behind his back.
With many brightly-coloured flowers planted around the building ,his house looks like a beautiful garden.
With everything well arranged,he left the office.
六、過去分詞、現(xiàn)在分詞、和不定式作賓補的區(qū)別。
現(xiàn)在分詞作賓補：賓語和補語之間是主謂關系。其動作與謂語動作同時進行。
過去分詞作賓補：賓語和補語之間是動賓關系。其動作先于謂語動作。
不定式作賓補： 表一個完成的動作、或表一個很短時間內(nèi)看到、聽到或感覺到的具體動作。
eg:He didn't notice me waiting.
I heard the song sung in English.
I saw him opening the window.
I saw the window opened.
I saw him open the window.
I heard her sing the song in English.
