考研英語(yǔ):語(yǔ)法
在我們平凡無(wú)奇的學(xué)生時(shí)代,很多人都經(jīng)常追著老師們要知識(shí)點(diǎn)吧,知識(shí)點(diǎn)就是“讓別人看完能理解”或者“通過(guò)練習(xí)我能掌握”的內(nèi)容。掌握知識(shí)點(diǎn)有助于大家更好的學(xué)習(xí)。以下是小編為大家整理的考研英語(yǔ):語(yǔ)法,歡迎大家借鑒與參考,希望對(duì)大家有所幫助。
什么是副詞
副詞(adverb)修飾動(dòng)詞、形容詞和其他副詞等,說(shuō)明時(shí)間、地點(diǎn)、程度、方式等概念。如:often往往,here這里,very很,quickly很快地。
副詞的構(gòu)成
1)本身就是副詞,如now現(xiàn)在,there那里,rather頗。
2)由形容詞加詞尾-1y變來(lái),如firmly堅(jiān)決地,happi1y幸福地。
3)與形容詞同形
early adj.早的early adv.早
high adj.高的high adv.高高地
long adj.長(zhǎng)的,長(zhǎng)久的long adv.長(zhǎng)久地
副詞的種類(lèi)
副詞可分為下列幾種:
1)普通副詞(ordinary adverb)如:together一起,well好,seriously認(rèn)真地,slowly慢,carefully小心地。
2)疑問(wèn)副詞(interrogative adverb)如:when何時(shí),where何地,how如何,why為何。
3)關(guān)系副詞(relative adverb)如:where,when.
4)連接副詞(conjunctive adverb)如:then然后,so所以,there{ore所以,however然而,hence所以,thus這樣,nevertheless然而,otherwise否則,still可是,仍然。
副詞的用法
副詞在句中可用作:
1)狀語(yǔ)(這是副詞在句子中的主要功用)
It is raining hard.雨下得很大。(副詞hard作狀語(yǔ),修飾動(dòng)詞is raining.)
Dont drive too fast.車(chē)子不要開(kāi)得太快。(fast是副詞,作狀語(yǔ),修飾動(dòng)詞drive,副詞too又修飾副詞fast.)
He speaks English quite well.他英語(yǔ)講得相當(dāng)好。(well修飾動(dòng)詞speaks,quite又修飾副詞well.)
This is a fairly useful tool,這是一件相當(dāng)有用的工具。(fairly修飾形容詞useful)
He has always helped his sister with her homework.他一向幫助他妹妹做家庭作業(yè)。(always修飾動(dòng)詞has helped)
She often went there.她常到那兒去。(often和there均是副詞,修飾動(dòng)詞went.)
Perhaps he will telephone later.也許他以后會(huì)打電話(huà)來(lái)的。(perhaps是副詞,用以修飾全句。)
2)表語(yǔ)
Is he up?他起床了沒(méi)有?
She is out.她出去了。
3)定語(yǔ)
Life here is full of joy.這兒的生活充滿(mǎn)了歡樂(lè)。(here修飾名詞life)
副詞的位置
1)修飾動(dòng)詞時(shí),有三種位置。
2)修飾形容詞和副詞時(shí),須放在被修飾詞之前。如:
It is a rather difficult job,這是一件頗為困難的工作。(rather修飾形容詞difficult)
He runs very fast.他跑得很快。(very修飾副詞fast)
3)副詞作定語(yǔ)時(shí),一般放在被修飾的名詞之后。如:
The peasants there are busy digging a canal now.那里的農(nóng)民現(xiàn)在正忙于修水渠。
On my way home,I met groups of Young Pioneers.在回家的路上我遇見(jiàn)成群的少先隊(duì)員。
副詞的比較等級(jí)
和形容詞同形的副詞的形式變化與形容詞完全相同。但以詞尾-1y結(jié)尾的副詞(注意early一詞的-1y不是副詞的詞尾)須用more和most.另外,須注意下面例詞中well,badly的不規(guī)則變化。如:
原級(jí)比較級(jí)最高級(jí)
hard努力地harderhardest
fast快faster fastest
well好better best
badly壞worseworst
early早earlier earliest
quickly快more quicklymost quickly
happily快樂(lè)地more happily most happily
副詞比較等級(jí)的用法
1)副詞比較級(jí)的用法與形容詞比較級(jí)相似。如:
David drives faster than anyone I know.大衛(wèi)開(kāi)車(chē)比我所知道的任何人都要快。
She plays table tennis better than I.她乒乓球打得比我好。(從句中省略了play table tennis)
Mr. Martin usually gets to the office earlier than others.馬丁先生到辦公室通常比別人早。
They speak less fluently but more correctly than we do.他們講得不如我們流利,但比我們正確。
2)副詞最高級(jí)用法,除副詞前可以不用the外(用the也可以),其余與形容詞最高級(jí)相同。如:
I work fastest when Im under pressure.我在有壓力時(shí)工作得最快。
He swims the best in Class One.一班他游泳最好。
比較等級(jí)的一些特殊用法
兩種不同形式
有幾個(gè)形容詞和副詞的比較級(jí)和最高級(jí)有兩種的比較等級(jí)不同形式,而且意義也不同。
舉例說(shuō)明:
1)Rome is one of the oldest cities in the world.羅馬是世界上最古老的城市之一。
Her eldest daughter is a school teacher.她大女兒是個(gè)教員。
My elder brother is in college. He is two years older than I.我哥哥在上大學(xué),他比我大兩歲。
注:older,oldest說(shuō)明人的年紀(jì)或事物的年代的久遠(yuǎn),但在美國(guó)英語(yǔ)里也表示長(zhǎng)幼。
2)They reached the place later than we.他們到達(dá)那兒比我們晚。
Twenty years later he returned to his home village.二十年后,他回到自己的家鄉(xiāng)。
3)Who spoke last?是誰(shuí)最后發(fā)言的?
What is the latest news about the sports meet?關(guān)于運(yùn)動(dòng)會(huì)最近有什么消息?
as……as;not so. . .as或not as……as
1)表示“相等”用as……as.
2)表示“不相等”用not so……as或not as……as.如:
1)This knife is as sharp as that one.這把刀跟那把一樣快。
Bill is as tall as I.比爾和我一般高。
Is this bag of soyabeans as heavy as that one?這袋大豆跟那袋一樣重嗎?
You know as well as I do.你和我一樣明白。
注:注意as后面的形容詞如作定語(yǔ),而被定語(yǔ)修飾的名詞有不定冠詞a時(shí),冠詞a須放在形容詞之后,如German is as difficult a language as English.(德語(yǔ)和英語(yǔ)一樣難學(xué)。)。這樣的詞序也適用于so,如I have never seen so beautiful a place as Guilin before.(我過(guò)去從未見(jiàn)過(guò)像桂林這樣美麗的地方。)
2)tian An Men Square was not so big as it is now.天安門(mén)廣場(chǎng)過(guò)去沒(méi)有現(xiàn)在這樣大。
The Atlantic Ocean is not as big as the Pacific ocean.大西洋沒(méi)有太平洋大。
表示“幾倍于”
用twice (兩倍),three times(三倍)等加as……as……
如:
New York is ten times as big as my home town.紐約有我的家鄉(xiāng)十個(gè)大。
The output of the paper mill is now three times as high as it was in 1966.這家紙廠(chǎng)的生產(chǎn)比一九六六年增加兩倍。

Our countys agricultural output this year is 5 per cent higher than that of last year.我們縣今年農(nóng)業(yè)產(chǎn)量比去年增長(zhǎng)百分之五。
表示程度
可用much,far,still,even,a 1itt1e,no,any,a great deal等狀語(yǔ)來(lái)修飾形容詞和副詞的比較級(jí)。如:
The Yellow River is long,but the Changjiang River is even longer.黃河長(zhǎng),長(zhǎng)江更長(zhǎng)。
We are much better off now.我們的生活比過(guò)去好得多。

I think he is the best possible man for the job.我認(rèn)為他做這工作最合適。(也可以說(shuō)the best man possibl
考研英語(yǔ)語(yǔ)法匯總
賓語(yǔ)從句就是由一個(gè)句子來(lái)構(gòu)成主句的賓語(yǔ),并有一個(gè)連接詞引導(dǎo)。引導(dǎo)賓語(yǔ)從句的連接詞分類(lèi):
。ㄒ唬⿵膶龠B詞
連接賓語(yǔ)從句的從屬連詞主要有that,if,whether。
1、that引導(dǎo)表示陳述句的賓語(yǔ)從句。當(dāng)賓語(yǔ)從句是陳述句時(shí)(包括肯定句和否定句),連詞由that引導(dǎo),因?yàn)閠hat在從句中不作任何成分,也沒(méi)有任何具體意思,因此在口語(yǔ)或非正式文體中常省略。例如:
Lin Tao feels (that) his own team is even better.
Jim thought (that) the train was like a big moving party.
He said (that) he would like to see the headmaster.
2、if和whether,whether...or not引導(dǎo)表示“是否”的一般疑問(wèn)句的賓語(yǔ)從句。例如:

我不知道是否還會(huì)有公交車(chē)。
Nobody knew whether he could pass the exam.
沒(méi)有人知道他是否會(huì)通過(guò)考試。
3、注意已下情況只用whether,不用if。
1) whether引導(dǎo)的從句?梢耘c連詞or或or not直接連用。例如:
Let me know whether you can come or not. (√ )
Let me know if you can come or not. (×)
2)當(dāng)賓語(yǔ)從句提到句首時(shí),只能用whether引導(dǎo)。例如:
Whether it is true or not, I can’t tell. (√ )
If it is true or not, I can’t tell. (×)
3) whether可以引導(dǎo)帶to的不定式。例如:
I don’t know whether to accept or refuse. (√ )
I don’t know if to accept or refuse. (×)
4)whether及其引導(dǎo)的成分可放于介詞之后,作介詞的賓語(yǔ)。例如:
I worry about whether I hurt her feelings. (√ )
I worry about if I hurt her feelings. (×)
(二)連接代詞
連接代詞主要有who,whom,whose,what,whoever,whomever,whosever,whatever, whichever等。連接代詞一般指疑問(wèn),但what, whatever除了指疑問(wèn)外,也可以指陳述。例如:
