高一上冊(cè)英語(yǔ)語(yǔ)法總結(jié) 用現(xiàn)在進(jìn)行時(shí)表示將來(lái)
意為："意圖"、"打算"、"安排"、常用于人。常用詞為 come, go, start, arrive, leave, stay等。 I'm leaving tomorrow.
Are you staying here till next week?
比較過(guò)去時(shí)與現(xiàn)在完成時(shí)
1）過(guò)去時(shí)表示過(guò)去某時(shí)發(fā)生的動(dòng)作或單純敘述過(guò)去的事情，強(qiáng)調(diào)動(dòng)作；現(xiàn)在完成時(shí)為過(guò)去發(fā)生的，強(qiáng)調(diào)過(guò)去的事情對(duì)現(xiàn)在的影響，強(qiáng)調(diào)的是影響。
2）過(guò)去時(shí)常與具體的時(shí)間狀語(yǔ)連用，而現(xiàn)在完成時(shí)通常與模糊的時(shí)間狀語(yǔ)連用，或無(wú)時(shí)間狀語(yǔ)。
一般過(guò)去時(shí)的時(shí)間狀語(yǔ):
yesterday, last week，…ago, in1980, in October, just now, 具體的時(shí)間狀語(yǔ)
共同的時(shí)間狀語(yǔ):
this morning, tonight,this April, now, once，before, already, recently，lately
現(xiàn)在完成時(shí)的時(shí)間狀語(yǔ)
for, since, so far, ever, never, just, yet, till / until, up to now, in past years, always, 不確定的時(shí)間狀語(yǔ)
3）現(xiàn)在完成時(shí)可表示持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)，動(dòng)詞一般是延續(xù)性的，如live, teach, learn, work, study, know.
過(guò)去時(shí)常用的非持續(xù)性動(dòng)詞有come, go, leave, start, die, finish, become, get married等。 舉例：
I saw this film yesterday.
（強(qiáng)調(diào)看的動(dòng)作發(fā)生過(guò)了。）
I have seen this film.
（強(qiáng)調(diào)對(duì)現(xiàn)在的影響，電影的內(nèi)容已經(jīng)知道了。）
Why did you get up so early?
（強(qiáng)調(diào)起床的動(dòng)作已發(fā)生過(guò)了。）
Who hasn't handed in his paper?
（強(qiáng)調(diào)有卷子，可能為不公平競(jìng)爭(zhēng)。）
She has returned from Paris.
她已從巴黎回來(lái)了。
She returned yesterday.
她是昨天回來(lái)了。
He has been in the League for three years.
(在團(tuán)內(nèi)的狀態(tài)可延續(xù))
He has been a League member for three years.(是團(tuán)員的狀態(tài)可持續(xù))
He joined the League three years ago.
( 三年前入團(tuán)，joined為短暫行為。)
I have finished my homework now.
---Will somebody go and get Dr. White?
---He's already been sent for.
句子中如有過(guò)去時(shí)的時(shí)間副詞（如 yesterday, last, week, in 1960）時(shí)，不能使用現(xiàn)在完成時(shí)，要用過(guò)去時(shí)。
（錯(cuò)）Tom has written a letter to his parents last night.
（對(duì)）Tom wrote a letter to his parents last night.
since的四種用法
1) since +過(guò)去一個(gè)時(shí)間點(diǎn) (如具體的年、月、日期、鐘點(diǎn)、1980, last month, half past six)。 I have been here since 1989.
2) since +一段時(shí)間+ ago
I have been here since five months ago.
3) since +從句
Great changes have taken place since you left.
Considerable time has elapsed since we have been here.
4) It is +一段時(shí)間+ since從句
It is two years since I became a postgraduate student.
延續(xù)動(dòng)詞與瞬間動(dòng)詞
1) 用于完成時(shí)的區(qū)別
延續(xù)動(dòng)詞表示經(jīng)驗(yàn)、經(jīng)歷； 瞬間動(dòng)詞表示行為的結(jié) 果，不能與表示段的時(shí)間狀語(yǔ)連用。 He has completed the work. 他已完成了那項(xiàng)工作。 (表結(jié)
結(jié)果)
I've known him since then. 我從那時(shí)起就認(rèn)識(shí)他了。(表經(jīng)歷)
2) 用于till / until從句的差異
延續(xù)動(dòng)詞用于肯定句，表示"做……直到……" 瞬間動(dòng)詞用于否定句，表示"到……，才……" He didn't come back until ten o'clock.
他到10 點(diǎn)才回來(lái)。
He slept until ten o'clock.
他一直睡到10點(diǎn)。
典型例題
1. You don't need to describe her. I ___ her several times.
A. had met B. have met C. met D. meet
答案B. 首先本題后句強(qiáng)調(diào)對(duì)現(xiàn)在的影響，我知道她的模樣，你不用描述。再次，several times告知為反復(fù)發(fā)生的動(dòng)作，因此用現(xiàn)在完成時(shí)。
2.---I'm sorry to keep you waiting.
---Oh, not at all. I ___ here only a few minutes.
A. have been B. had been C. was D. will be
答案A. 等待的動(dòng)作由過(guò)去開(kāi)始，持續(xù)到現(xiàn)在，應(yīng)用現(xiàn)在完成時(shí)。
用一般過(guò)去時(shí)代替完成時(shí)
1) 兩個(gè)動(dòng)作如按順序發(fā)生，又不強(qiáng)調(diào)先后，或用then，and，but 等連詞時(shí)，多用一般過(guò)去時(shí)。
When she saw the mouse，she screamed.
My aunt gave me a hat and I lost it.
2 ) 兩個(gè)動(dòng)作相繼發(fā)生，可用一般過(guò)去時(shí)；如第一個(gè)動(dòng)作需要若干時(shí)間完成，用過(guò)去完成時(shí)。 When I heard the news, I was very excited.
3) 敘述歷史事實(shí)，可不用過(guò)去完成時(shí)，而只用一般過(guò)去時(shí)。
Our teacher told us that Columbus discovered America in 1492.
不用進(jìn)行時(shí)的動(dòng)詞
1) 事實(shí)狀態(tài)的動(dòng)詞
have, belong, possess, cost, owe, exist, include, contain, matter, weigh, measure, continue
I have two brothers.
This house belongs to my sister.
2) 心理狀態(tài)的動(dòng)詞

accept, receive, complete, finish, give, allow, decide, refuse.
I accept your advice.
4) 系動(dòng)詞
seem, remain, lie, see, hear, smell, feel, taste, get, become, turn
You seem a little tired.
虛擬語(yǔ)氣1） 概念
虛擬語(yǔ)氣用來(lái)表示說(shuō)話人的主觀愿望或假想，所說(shuō)的是一個(gè)條件，不一定是事實(shí)，或與事實(shí)相反。
2） 在條件句中的應(yīng)用
條件句可分為兩類，一類為真實(shí)條件句，一類為非真實(shí)條件句。非真實(shí)條件句表示的是假設(shè)的或?qū)嶋H可能性不大的情況，故采用虛擬語(yǔ)氣。
真實(shí)條件句
真實(shí)條件句用于陳述語(yǔ)氣，假設(shè)的情況可能發(fā)生，其中 if 是如果的意思。
時(shí)態(tài)關(guān)系
句型： 條件從句 主句
一般現(xiàn)在時(shí) shall/will + 動(dòng)詞原形
If he comes, he will bring his violin.
典型例題
The volleyball match will be put off if it ___.
A. will rain B. rains C. rained D. is rained
答案B。真實(shí)條件句主句為將來(lái)時(shí)，從句用一般現(xiàn)在時(shí)。
注意：
1） 在真實(shí)條件句中，主句不能用be going to表示將來(lái)，該用shall, will.
(錯(cuò)) If you le
ave now, you are never going to regret it.
(對(duì)) If you leave now, you will never regret it.
2） 表示真理時(shí)，主句謂語(yǔ)動(dòng)詞便不用shall (will) +動(dòng)詞原形，而直接用一般現(xiàn)在時(shí)的動(dòng)詞形式。
非真實(shí)條件句
1）時(shí)態(tài)：可以表示過(guò)去，現(xiàn)在和將來(lái)的情況。它的基本特點(diǎn)是時(shí)態(tài)退后。
a. 同現(xiàn)在事實(shí)相反的假設(shè)。
句型 ： 條件從句 主句
一般過(guò)去時(shí) should( would) +動(dòng)詞原形
If they were here, they would help you.
b. 表示于過(guò)去事實(shí)相反的假設(shè)。
句型： 條件從句 主句
過(guò)去完成時(shí) should(would) have+ 過(guò)去分詞
If she had worked harder, she would have succeeded.The rice would not have been burnt if you had been more careful.
If my lawyer had been here last Saturday, he would have prevented me from going.
If he had come yesterday, I should / would have told him about it.
含義：He did not come yesterday, so I did not tell him about it.
If he had not been ill and missed many classes, he would have made greater progress. 含義： He was ill and missed many lessons, so he did not make greater progress.
c. 表示對(duì)將來(lái)的假想
句型： 條件從句 主句
一般過(guò)去時(shí) should+ 動(dòng)詞原形
were+ 不定式 would + 動(dòng)詞原形
should+ 動(dòng)詞原形
If you succeeded, everything would be all right.
If you should succeed, everything would be all right.
If you were to succeed, everything would be all right.
混合條件句
主句與從句的動(dòng)作發(fā)生在不同的時(shí)間，這時(shí)主，從句謂語(yǔ)動(dòng)詞的虛擬語(yǔ)氣形式因時(shí)間不同而不同，這叫做混合條件句。
If you had asked him yesterday, you would know what to do now.
（從句與過(guò)去事實(shí)相反，主句與現(xiàn)在事實(shí)相反。）
If it had rained last night (過(guò)去), it would be very cold today (現(xiàn)在).
虛擬條件句的倒裝
虛擬條件句的從句部分如果含有were, should, 或had, 可將if省略，再把were, should或had 移到從句句首，實(shí)行倒裝。
Were they here now, they could help us.
=If they were here now, they could help us.
Had you come earlier, you would have met him
=If you had come earlier, you would have met him.
Should it rain, the crops would be saved.
=Were it to rain, the crops would be saved.
注意：
在虛擬語(yǔ)氣的從句中，動(dòng)詞'be'的過(guò)去時(shí)態(tài)一律用"were"，不用was， 即在從句中be用were代替。
If I were you, I would go to look for him.
如果我是你，就會(huì)去找他。
If he were here, everything would be all right.如果他在這兒，一切都會(huì)好的。
典型例題
_____ to do the work, I should do it some other day.
A. If
were I B. I were C. Were I D. Was I
答案C. 在虛擬條件狀語(yǔ)中如果有were, should, had這三個(gè)詞，通常將if省略，主語(yǔ)提前, 變成 were, should, had +主語(yǔ)的形式。但要注意，在虛擬條件狀語(yǔ)從句中，省略連詞的倒裝形式的句首不能用動(dòng)詞的縮略形式。如我們可說(shuō) Were I not to do., 而不能說(shuō) Weren't I to do.
特殊的虛擬語(yǔ)氣詞：should
1） It is demanded / necessary / a pity + that…結(jié)構(gòu)中的主語(yǔ)從句的謂語(yǔ)動(dòng)詞要用should 加動(dòng)詞原形， should 可省略。
句型：
(1)suggested
It is (2)important that…+ (should) do
(3) a pity
(1)suggested, ordered, proposed, required, demanded, requested, insisted； + (should) do
(2)important, necessary, natural, strange
a pity, a shame, no wonder
(3)It is suggested that we (should) hold a meeting next week.
It is necessary that he (should) come to our meeting tomorrow.
2）在賓語(yǔ)從句中的應(yīng)用
在表示命令、建議、要求等一類動(dòng)詞后面的從句中。
order, suggest, propose, require, demand, request, insist, command, insist + (should) do I suggest that we (should) hold a meeting next week.
He insisted that he (should ) be sent there.
注意： 如suggest, insist不表示"建議" 或"堅(jiān)持要某人做某事時(shí)"，即它們用于其本意"暗示、表明"、"堅(jiān)持認(rèn)為"時(shí)，賓語(yǔ)從句用陳述語(yǔ)氣。
The guard at gate insisted that everybody obey the rules.
判斷改錯(cuò):
（錯(cuò)） You pale face suggests that you (should) be ill.
(對(duì)) Your pale face suggests that you are ill.
(錯(cuò)) I insisted that you ( should) be wrong.
(對(duì)) I insisted that you were wrong.
3）在表語(yǔ)從句，同位語(yǔ)從句中的應(yīng)用
在suggestion, proposal, idea, plan, order, advice等名詞后面的表語(yǔ)從句、同位語(yǔ)從句中要用虛擬語(yǔ)氣，即（should）+動(dòng)詞原形。
My idea is that we (should) get more people to attend the conference.
I make a proposal that we (should) hold a meeting next week.
比較if only與only if
only if表示"只有"；if only則表示"如果……就好了"。If only也可用于陳述語(yǔ)氣。
I wake up only if the alarm clock rings. 只有鬧鐘響了，我才會(huì)醒。
If only the alarm clock had rung. 當(dāng)時(shí)鬧鐘響了，就好了。
If only he comes early. 但愿他早點(diǎn)回來(lái)。
關(guān)系代詞所代替的先行詞是人或物的名詞或代詞，并在句中充當(dāng)主語(yǔ)、賓語(yǔ)、定語(yǔ)等成分。關(guān)系代詞在定語(yǔ)從句中作主語(yǔ)時(shí)，從句謂語(yǔ)動(dòng)詞的人稱和數(shù)要和先行詞保持一致。
1）who, whom, that
這些詞代替的先行詞是人的名詞或代詞，在從句中所起作用如下：
Is he the man who/that wants to see you?
他就是你想見(jiàn)的人嗎？（who/that在從句中作主語(yǔ)）
He is the man whom/ that I saw yesterday.
他就是我昨天見(jiàn)的那個(gè)人。（
whom/that在從句中作賓語(yǔ)）
2) Whose 用來(lái)指人或物，(只用作定語(yǔ), 若指物，它還可以同of which互換）, 例如： They rushed over to help the man whose car had broken down. 那人車壞了，大家都跑過(guò)去幫忙。
Please pass me the book whose (of which) cover is green. 請(qǐng)遞給我那本綠皮的書(shū)。
3）which, that
它們所代替的先行詞是事物的名詞或代詞，在從句中可作主語(yǔ)、賓語(yǔ)等，例如：
A prosperity which / that had never been seen before appears in the countryside. 農(nóng)村出現(xiàn)了前所未有的繁榮。（which / that在句中作賓語(yǔ)）
The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作賓語(yǔ)）
關(guān)系副詞可代替的先行詞是時(shí)間、地點(diǎn)或理由的名詞，在從句中作狀語(yǔ)。
1）when, where, why
關(guān)系副詞when, where, why的含義相當(dāng)于"介詞+ which"結(jié)構(gòu)，因此常常和"介詞+ which"結(jié)構(gòu)交替使用，例如：
There are occasions when (on which) one must yield. 任何人都有不得不屈服的時(shí)候。 Beijing is the place where (in which) I was born. 北京是我的出生地。
Is this the reason why (for which) he refused our offer? 這就是他拒絕我們幫助他的理由嗎？
2）that代替關(guān)系副詞
that可以用于表示時(shí)間、地點(diǎn)、方式、理由的名詞后取代when, where, why和"介詞+ which"引導(dǎo)的定語(yǔ)從句，在口語(yǔ)中that常被省略，例如：
His father died the year (that / when / in which) he was born. 他父親在他出生那年逝世了。 He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住過(guò)的地方。
方法一：用關(guān)系代詞，還是關(guān)系副詞完全取決于從句中的謂語(yǔ)動(dòng)詞。及物動(dòng)詞后面無(wú)賓語(yǔ)，就必須要求用關(guān)系代詞；而不及物動(dòng)詞則要求用關(guān)系副詞。例如：
This is the mountain village where I stayed last year.
I'll never forget the days when I worked together with you.
判斷改錯(cuò)（注：先顯示題，再顯示答案，橫線；用不同的顏色表示出。）
（錯(cuò)） This is the mountain village where I visited last year.
（錯(cuò)） I will never forget the days when I spent in the countryside.
（對(duì)） This is the mountain village (which) I visited last year.
（對(duì)） I'll never forget the days (which) I spent in the countryside.
習(xí)慣上總把表地點(diǎn)或時(shí)間的名詞與關(guān)系副詞 where, when聯(lián)系在一起。此兩題錯(cuò)在關(guān)系詞的誤用上。
方法二： 準(zhǔn)確判斷先行詞在定語(yǔ)從句中的成分(主、謂、賓、定、狀)，也能正確選擇出關(guān)系代詞/關(guān)系副詞。
例1. Is this museum ___ you visited a few days age?
A. where B. that C. on which D. the one
例2. Is this the museum ____ the exhibition was held.
A. where B. that C. on which D. the one
答案：例1 D，例2 A
例1變?yōu)榭隙ň洌?This museum is ___ you visited a few days ago.
例2變?yōu)榭?/P>1234567下一頁(yè)
定句： This is the museum ___ the exhibition was held.
在句1中，所缺部分為賓語(yǔ)，而where, that, on which都不能起到賓語(yǔ)的作用，只有the one既做了主句的表語(yǔ)，又可做從句的賓語(yǔ)，可以省略關(guān)系代詞，所以應(yīng)選D。
而句2中, 主、謂、賓俱全，從句部分為句子的狀語(yǔ)表地點(diǎn)，既可用副詞where，又因 in the museum詞組，可用介詞in + which 引導(dǎo)地點(diǎn)狀語(yǔ)。而此題中，介詞on 用的不對(duì)，所以選A。
關(guān)系詞的選擇依據(jù)在從句中所做的成分，先行詞在從句中做主、定、賓語(yǔ)時(shí)，選擇關(guān)系代詞 (who, whom, that, which, whose)； 先行詞在從句中做狀語(yǔ)時(shí)，應(yīng)選擇關(guān)系副詞 ( where 地點(diǎn)狀語(yǔ)，when 時(shí)間狀語(yǔ)，why 原因狀語(yǔ)) 。
限制性和非限制性定語(yǔ)從句
1) 定語(yǔ)從句有限制性和非限制性兩種。限制性定語(yǔ)從句是先行詞不可缺少的部分，去掉它主句意思往往不明確；非限制性定語(yǔ)從句是先行詞的附加說(shuō)明，去掉了也不會(huì)影響主句的意思，它與主句之間通常用逗號(hào)分開(kāi)，例如：
This is the house which we bought last month. 這是我們上個(gè)月買的那幢房子。（限制性） The house, which we bought last month, is very nice.這幢房子很漂亮，是我們上個(gè)月買的。（非限制性）
2) 當(dāng)先行詞是專有名詞或物主代詞和指示代詞所修飾時(shí)，其后的定語(yǔ)從句通常是非限制性的，例如：
Charles Smith, who was my former teacher, retired last year. 查理?史密斯去年退休了，他曾經(jīng)是我的老師。
My house, which I bought last year, has got a lovely garden. 我去年買的的那幢房子帶著個(gè)漂亮的花園。
This novel, which I have read three times, is very touching. 這本小說(shuō)很動(dòng)人，我已經(jīng)讀了三遍。
3) 非限制性定語(yǔ)從句還能將整個(gè)主句作為先行詞, 對(duì)其進(jìn)行修飾, 這時(shí)從句謂語(yǔ)動(dòng)詞要用第三人稱單數(shù)，例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎沒(méi)抓住我的意思，這使我心煩。
Liquid water changes to vapor, which is called evaporation. 液態(tài)水變?yōu)檎羝�，這就叫做蒸發(fā)。
說(shuō)明：關(guān)系代詞that和關(guān)系副詞why不能引導(dǎo)非限制性定語(yǔ)從句。
由as, which 引導(dǎo)的非限定性定語(yǔ)從句，as和which可代整個(gè)主句，相當(dāng)于and this或and that。As一般放在句首，which在句中。
As we know, smoking is harmful to one's health.
The sun heats the earth, which is very important to us.
典型例題
1）Alice received an invitation from her boss, ___came as a surprise.
A. it B. that C. which D. he
答案C. 此為非限定性從句，不能用 that修飾，而用which.，it 和he 都使后句成為句子，兩個(gè)獨(dú)立的句子不能單以逗號(hào)連接。況且選he句意不通。
2）The weather turned out to be very good, ___ was more than we could expect.
A. what B. which C. that D. it
答案B。which可代替句子，用于非限定性定語(yǔ)從句，而what不可。That 不能用于非限定性定語(yǔ)從句，it不為連詞，使由逗號(hào)連接的兩個(gè)句子并在一起在英語(yǔ)語(yǔ)法上行不通。
3）It rained hard yesterday, ____ prevented me from going to the park..
A. that B. which C. as D. it
答案B.
as 和which在引導(dǎo)非限制性定語(yǔ)從句時(shí)，這兩個(gè)關(guān)系代詞都指主句所表達(dá)的整個(gè)意思，且在定語(yǔ)從句中都可以作主語(yǔ)和賓語(yǔ)。但不同之處主要有兩點(diǎn)：
(1） as 引導(dǎo)的定語(yǔ)從句可置于
句首，而which不可。
(2） as 代表前面的整個(gè)主句并在從句中作主語(yǔ)時(shí)，從句中的謂語(yǔ)必須是系動(dòng)詞；若為行為動(dòng)詞，則從句中的關(guān)系代詞只能用which.。
在本題中，prevent由于是行為動(dòng)詞，所以正確選項(xiàng)應(yīng)為B。
As 的用法
例1. the same… as；such…as 中的as 是一種固定結(jié)構(gòu), 和……一樣……。
I have got into the same trouble as he (has).
例2. as可引導(dǎo)非限制性從句，常帶有'正如'。
As we know, smoking is harmful to one's health.
As is know, smoking is harmful to one's health.
As是關(guān)系代詞。例1中的as作know的賓語(yǔ)；例2中，它充當(dāng)從句的主語(yǔ)，謂語(yǔ)動(dòng)詞know要用被動(dòng)式。
