高三英語語法知識點1
虛擬語氣
I?虛擬語氣在if?引導的條件句中的易錯點。?
①?if?my?lawyer?had?been?here?last?Saturday,?he?would?have?prevented?me?from?going.?
②?if?you?had?studied?hard?at?school,?you?would?be?a?college?student?now.?
句子①②都是虛擬語氣在條件句中的使用，從句中都是假設過去的情況，所以用過去完成時，但在主句中，句①依然指代過去的情況，謂語動詞是would?have?done，而②中含有一個表示現(xiàn)在的時間狀語now,?這樣就必須將其理解為假設現(xiàn)在的情況，所以謂語動詞必須為would/should/might+動詞原形，學生在這一點上經(jīng)常會忽略now的存在，從而按句①的形式填寫答案。??
Ⅱ虛擬語氣在名詞性從句中的用法??
1.在it?is?important?(strange,?natural,?necessary……)+that?句子或者It?is?decided?(ordered,suggested,?demanded,?advised……)+that句子中，主語從句中的謂語動詞常用(should)+動詞原形結構，表示某事“重要”、“必要”、“被決定”等?
例如：①?it?is?important?that?everyone?(should?)?obey?the?rules?all?day?and?all?night.?
②?it?is?decided?that?the?meeting?(should)?be?held?tomorrow?afternoon.?
2.?suggest,?insist?后面指賓語從句時需注意的地方??
1)①suggest?當“建議”“提出”講時，其后賓語從句的謂語動詞常用“should+動詞原形”?例如：He?suggested?that?the?work?(should)?be?started?at?once?他建議立即動工。?
類似的動詞還有insist堅持，demand要求，desire要求、請求，request請求，require要求、需要，order命令，propose建議，command命令，ask要求，advise建議，prefer寧愿等。?這些動詞變被動語態(tài)(如：It?is?suggested?+?that主語從句)形式后，主語從句謂語動詞仍用“(should)+動詞原形”?這些動詞變名詞(如suggestion)后，其后的表語從句和同位語從句中的謂語部分仍用“(should)+動詞原形”?
②suggest?當“提出(某看法)，暗示，啟發(fā)”講時，其后賓語從句的動詞不用虛擬語氣。?例如：(1)The?police?suggested?that?the?thief?might?be?one?of?the?family?member?
警察局提出竊賊可能是一名家庭成員。?
(2)Her?yawns?suggests?that?she?is?sleepy.?她打哈欠表明她困了。?
(3)Although?he?didn’t?suggest?that?we?__?the?decision?to?swim?across?the?river,?but?his?look?suggested?that?our?decision?__wrong.雖然他沒提出我們應該終止游過這條河的決定，但他的表情表明我們的決定是錯誤的。?
A：stop;?wasB:?should?stop;?be
C:?stopped?;wasD:?stopped;?should?be?
在這個句子中，前一個suggest當“建議”“提出”講，而后一個作“表明”講，所以答案為“A”??
2)①insist作“堅決要求…該…;堅持認為…定要…”講時，其后賓語從句的謂語動詞用“(should)+動詞原形”?
例如：I?insisted?that?you?(should)?be?there?on?time.我堅持認為你應該準時到那里去?
②insist?作“堅持(意見，看法);堅持說，確信”講時，其后從句不用虛擬語氣。
例如：He?suggested?(that)?he?heard?someone?in?the?next?room.?他堅持說他聽到隔壁屋子里有人。???

一、that 從句
1、主語從句
(1)that從句作主語時，常用it作形式主語，常見的句型有：
It+be+形容詞(obvious, true, natural, surprising,good,wonderful,funny,possible,likely,certain,probable,etc.)+that從句
It+be+名詞詞組(no wonder, an honor, a good thing, a pity, no surprise, etc.)+that從句
It+be+過去分詞(said, reported, thought, expected, decided, announced, arranged, etc.)+that從句
(2)that可以省略，但that從句位于句首時，that不能省略。
2、賓語從句
(1)常見的可以接that從句作賓語的動詞有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid等。在可以接復合賓語的動詞之后，如think, make, consider等，可以用it作形式賓語。
(2)That從句一般不能充當介詞賓語，偶爾可作except, in 的賓語。
3、表語從句(that不可省略)
4、同位語從句
連詞that引導同位語從句時，應在某些抽象名詞之后，如：fact, hope, desire, thought, suggestion, idea, news, problem, possibility等，對前面的名詞起補充說明的作用，that在從句中不擔當任何成分，不能省略。
二、whether/if從句
1、在表語從句和同位語從句中只能用whether不能用if;當主語從句放于句首時，只能用whether不用if;當it作形式主語，主語從句放在句末時用whether或if均可;discuss后引導賓語從句時，必須用whether。
2、在賓語從句中：
(1)及物動詞后：whether從句中不能有否定式，賓語從句為否定句時用if;if不能與or not連用，但可以用whether or not;whether后可以加不定式。
(2)介詞后：只能用whether,不用if。

高三英語語法知識點5
1.The boss of the company is trying to create an easy atmosphere __where__his employees enjoy their work.
解析：本句中定語從句“his employees enjoy their work”不缺主賓表，先行詞為atmosphere，表示“氣氛，氛圍”。將“in+先行詞atmosphere”還原回從句中成立，因此答案為where。
2.As the smallest child of his family，Alex is always longing for the time __when__he should be able to be independent.
解析：分析結構可知，此處是定語從句，先行詞為time。定語從句為空格后句子，缺少時間狀語，用when引導。句意：作為家里最小的孩子，亞歷克斯總是渴望他應該能獨立的時候。
3. Some experts think reading is the fundamental skill upon __which__ school education depends.
解析：本句為定語從句。引導詞在定語從句中位于介詞upon的后面作賓語，故用關系代詞且指代先行詞the fundamental skill，因此用which。
4.It is a truly delightful place, __which__ looks the same as it must have done 100 years ago with its winding streets and pretty cottages.
解析：此句是一個非限制性定語從句，先行詞是place，定語從句中缺主語，故用關系代詞which。句意：這真是一個宜人的地方，這里蜿蜒的小路和美麗的小村莊一定和100年前看起來是一模一樣的。
5.The books on the desk，__whose__covers are shiny，are prizes for us.
解析：此句是非限制性定語從句，先行詞為the books，________和covers之間存在所有關系，意為“書的封面”。句意：桌上的書是給我們的獎勵，那些書的封面閃閃發(fā)光。根據(jù)語境填whose。
6.He wrote many children's books，nearly half of __which__ were published in the 1990s.
解析：此句為非限制性定語從句，先行詞是children's books，定語從句中of缺少賓語，故填which。句意：他寫了許多兒童書籍，差不多一半左右是在20世紀90年代出版的。
7.Nowadays，school violence is a hot issue. I think this is a phenomenon，__which__calls for our great concern.
解析：句意：目前，學校暴力是個熱點問題。我認為這是一個需要我們極大的關注的現(xiàn)象。從句子結構分析可以看出，空白后面句子是一個非限制性定語從句，對前面句子進行補充說明。
