高三英語文科考試必考知識點概括1
虛擬語氣在一些特殊詞中的使用或含蓄條件句
後的賓語從句。
與現在願望不一致，用主語十過去時，例如：
I wi。hIwere you.
與過去願望不一致，用主語+had+過去分詞，例如：Iwish I had visited the White House whenI was inthe States與將來願望不一致，用主語+would (could)+原形。
's time句型：當lt's tine後用that從句時應該爲主i吾+should+動詞原形或主語十過去時，例如：It，s timethatyou went to school.或It's time that you should go to schooL
3- If only引起的感嘆句相當於“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。
d rather，asif(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爲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 favorablecondition等。
(2)連詞。如so that, unless, in case, supposing,lest, provided(倘若……)，for fearthat(唯恐)，in orderthat, on condition that, if only(要是……就好了)等。
注意：lest, for fear that和incase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 teacherspokeslowly 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着含蓄條件。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!

解釋：
1. 主語從句能用it作形式上的主語。常以it作形式主語的句型有：
A. It+be+形容詞(obvious, true, natural, surprising, good, wonderful, funny,possible, likely, certain, probable, etc.)+that從句。如：
It is certain that she will do well in her exam. 毫無疑問她考試成績會很好。
It is probable that he told her everything. 很可能他把一切都告訴她了。
B. It+be+名詞詞組(no wonder, an honour, a good thing, a pity, no surprise,etc.)+that從句。如：
It’s a pity that we can’t go. 很遺憾我們不能去。
It’s no surprise that our team should have won the game. 我們沒贏這場比賽真意外。
C. It+be+過去分詞(said, reported, thought, expected, decided, announced,arranged, etc.)+that從句。如：
It is said that Mr. Green has arrived in Beijing. 據說格林先生已經到了北京。
It is reported that China has sent another man-made earth satellite intoorbit.
據報道中國又成功地發射了一顆人造地球衛星。
D. It+seem, happen等不及物動詞及短語+that從句。如：
It seems that Alice is not coming to the party at all. Alice似乎不來參加晚會。
It happened that I was out that day. 碰巧我那天外出了。
E. It+doesn’t matter (makes no difference, etc.)+連接代詞或連接副詞引起的主語從句。如：
It doesn’t matter whether she will come or not. 她是否來這無關緊要。
It makes no difference where we shall have the meeting. 我們在哪裏開會毫無區別。
F. 當that引導的主語從句出現在疑問句中時，要以it作形式主語，而把主語從句後置。如：
Is it true that the scientist will give us a lecture next week?下週那位科學家將給我們作報告是真的嗎?
Does it matter much that they will not come tomorrow? 他們明天不來很要緊嗎?
G. 當主語從句出現在感嘆句中時，要以it作形式主語，而把主語從句後置。如：
How strange it is that the children are so quiet! 孩子們這麼安靜真奇怪!
2.注意連接代詞whoever, whatever, whichever等引導主語從句的含義
Whoever comes will be welcome. (whoever=the person who) 來的人將受到歡迎。
Whatever he did was right. (whatever=the thing that) 他所做的事情是正確的。
Whichever of you comes in will receive a prize. (whichever=anyone of youwho) 你們當中不論哪個進來將會得到獎
