高中英語知識點總結 人教版(一)
虛擬條件句
條件狀語從句是非真實情況,在這種情況下要用虛擬語氣。
l-條件從句與現(xiàn)在事實不一致,句型為:If+主語十過去時,tiag+should (could,would,或might)+動詞原形,例如:If l were you,1 would study hard.
2.條件從句與過去事實不一致,句型為:If+主語+had+過去分詞,主語+should(could, would,或might)+have+過去分詞,例如:If I had not studied hard.1would have failed in the exam last term
3.條件從句與將來事實不一致,句型為:lf+主語+should/were to+do,主語+should( could.)+原形do,例如:If l were to go to the moon one day,I could see itwith my own eyes.
注意:
1.If條件句中絕對不可出現(xiàn)“would”。
2-根據(jù)句中的時間狀語,有時可能出現(xiàn)“混合虛擬”的情況,即主句可能是現(xiàn)在的情況,條件句也許是發(fā)生在過去的情況,但都遵守上述句型。
3.在條件句中如果出現(xiàn)were,had,should可省去if'
將這些詞提前置于句首構成倒裝,例如:w。re I to go tothe moon one clay,1 would see it with my own eyes.如果有一天我登上月球,我就可以親眼目睹它的樣子了。

名詞性虛擬語氣
在表示命令、建議、要求、驚嘆的名詞性從句中需用虛擬語氣?;揪湫蜑椋褐髡Z+should+動詞原形,例如:
1.Mother insisted that John (should) go to bed atnine o'clock(賓語從句)
2.It was required that the crops (should) be:harvested at once.(主語從句)
3.The suggestion that he (should) be invited wasrejected.(同位語從句)
4.That is their demand that their wages (should) bemcreased.(表語從句)
注意:在這種句子中絕不能出現(xiàn)“would”“must”“could”等。

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)通過上下文及內在含義,句中往往有but,otherwise, unfortunately等類似轉折詞。
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
?、贐ut 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.
?、軮 would have come to the party yesterday, but ljwas working.
⑥I am busy now, otherwise l would do you the favor!

副詞的排列順序:
1) 時間,地點副詞,小單位的在前,大單位在后。
2) 方式副詞,短的在前,長的在后,并用and或but等連詞連接。
Please write slowly and carefully.
3) 多個不同副詞排列:程度+地點+方式+時間副詞。
注意:副詞very 可以修飾形容詞,但不能修飾動詞。
改錯:(錯) I very like English.
(對) I like English very much.
注意:副詞enough要放在形容詞的后面,形容詞enough放在名詞前后都可。
I don't know him well enough.
There is enough food for everyone to eat.
There is food enough for everyone to eat.

Who / whoever, what / whatever等的用法區(qū)別
一般說來,what/who等含特指意義,而whatever/whoever等含泛指意義,意為"無論什么/無論誰"。
It is generally considered unwise to give a child ____ he or she wants.
A. however B. whatever C. whichever D. whenever
解析:答案是B,whatever引導一個賓語從句,并且作wants的賓語。這里的 whatever不能改成what,因為題意想表達的顯然是"無論孩子要什么就給他/她什么事不明智的",具有泛指的概念。同時要注意,這里 whatever也不能改用no matter what,因為后者只能引導狀語從句。比較下例:
I can't remember at the moment who has said the words. (這里的who表特定的某人)
Where, when, why等連接副詞引導的名詞性從句
Where, when, why等連接副詞也可以引導名詞性從句,使用的關鍵是:這個詞必須符合句子的邏輯要求。
-I drove to Zhuhai for the air show last week.
-Is that ____ you had a few days off?
A. why B. when C. that D. where
解析:答案是A,why引導的從句作表語,同時why在從句中作原因狀語。這里之所以選why,而不是when或 where等,唯一的依據(jù)便是句子的邏輯含義,及語境。
"介詞+who(m)引導的賓語從句"與"介詞+ whom"引導的定語從句的區(qū)別
介詞后面的引導詞用主格還是賓格,決定于它在賓語從句中作主語還是賓語。
It was a matter of ____ would take the position.
A. who B. whoever C. whom D. whomever
解析:答案是A。這是一個含賓語從句的復合句,作介詞of賓語的,是后面的整個句子,而不是賓語從句的引導詞,由于這里引導詞在從句中作主語,所以要用主格who(作賓語時自然要用whom)。
