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。???

高三英語語法知識點2

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。
