試題詳情

2007年英語(yǔ)高考復(fù)習(xí)第一部分  詞法

第1章  主謂一致

一.概念:

主謂一致是指:

1) 語(yǔ)法形式上要一致,即單復(fù)數(shù)形式與謂語(yǔ)要一致。

2) 意義上要一致,即主語(yǔ)意義上的單復(fù)數(shù)要與謂語(yǔ)的單復(fù)數(shù)形式一致。

3) 就近原則,即謂語(yǔ)動(dòng)詞的單復(fù)形式取決于最靠近它的詞語(yǔ),

    一般來(lái)說(shuō),不可數(shù)名詞用動(dòng)詞單數(shù),可數(shù)名詞復(fù)數(shù)用動(dòng)詞復(fù)數(shù)。例如:

     There is much water in the thermos.

    但當(dāng)不可數(shù)名詞前有表示數(shù)量的復(fù)數(shù)名詞時(shí),謂語(yǔ)動(dòng)詞用復(fù)數(shù)形式。例如:

     Ten thousand tons of coal were produced last year.

二.相關(guān)知識(shí)點(diǎn)精講

1.并列結(jié)構(gòu)作主語(yǔ)時(shí)謂語(yǔ)用復(fù)數(shù),例如:

   Reading and writing are very important. 讀寫(xiě)很重要。

   注意:當(dāng)主語(yǔ)由and連結(jié)時(shí),如果它表示一個(gè)單一的概念,即指同一人或同一物時(shí),謂語(yǔ)動(dòng)詞用單數(shù),and 此時(shí)連接的兩個(gè)詞前只有一個(gè)冠詞。例如:

   The iron and steel industry is very important to our life. 鋼鐵工業(yè)對(duì)我們的生活有重要意義。

典型例題

   The League secretary and monitor ___ asked to make a speech at the meeting.

A. is  B. was  C. are  D. were

答案B. 注: 先從時(shí)態(tài)上考慮。這是過(guò)去發(fā)生的事情應(yīng)用過(guò)去時(shí),先排除A.,C。本題易誤選D,因?yàn)門(mén)he League secretary and monitor 好象是兩個(gè)人,但仔細(xì)辨別,monitor 前沒(méi)有the,在英語(yǔ)中,當(dāng)一人兼數(shù)職時(shí)只在第一個(gè)職務(wù)前加定冠詞。后面的職務(wù)用and 相連。這樣本題主語(yǔ)為一個(gè)人,所以應(yīng)選B。

2. 主謂一致中的靠近原則

1)當(dāng)there be 句型的主語(yǔ)是一系列事物時(shí),謂語(yǔ)應(yīng)與最鄰近的主語(yǔ)保持一致。例如:

 There is a pen, a knife and several books on the desk. 桌上有一支筆、一把小刀和幾本書(shū)。

 There are twenty boy-students and twenty-three girl-students in the class.班上有二十個(gè)男孩,二十三個(gè)女孩。

2)當(dāng)either… or… 與neither… nor,連接兩個(gè)主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞與最鄰近的主語(yǔ)保持一致。如果句子是由here, there引導(dǎo),而主語(yǔ)又不止一個(gè)時(shí),謂語(yǔ)通常也和最鄰近的主語(yǔ)一致。例如:

 Either you or she is to go. 不是你去,就是她去。

 Here is a pen, a few envelops and some paper for you. 給你筆、信封和紙。

3.謂語(yǔ)動(dòng)詞與前面的主語(yǔ)一致

當(dāng)主語(yǔ)有with, together with, like, except, but, no less than, as well as 等詞組成的短語(yǔ)時(shí),謂語(yǔ)動(dòng)詞與前面的主語(yǔ)部分一致。例如:

   The teacher together with some students is visiting the factory. 教師和一些學(xué)生在參觀工廠。

   He as well as I wants to go boating.他和我想去劃船。

4. 謂語(yǔ)需用單數(shù)的情況

1)代詞each以及由every, some, no, any等構(gòu)成的復(fù)合代詞作主語(yǔ)時(shí),或主語(yǔ)中含有each, every時(shí), 謂語(yǔ)需用單數(shù)。例如:

    Each of us has a tape-recorder. 我們每人都有錄音機(jī)。

    There is something wrong with my watch. 我的表壞了。

2)當(dāng)主語(yǔ)是一本書(shū)或一條格言時(shí),謂語(yǔ)動(dòng)詞常用單數(shù)。例如:

    The Arabian Night is a book known to lovers of English. 《天方夜譚》是英語(yǔ)愛(ài)好者熟悉的一本書(shū)。

 3)表示金錢(qián),時(shí)間,價(jià)格或度量衡的復(fù)合名詞作主語(yǔ)時(shí),通常把這些名詞看作一個(gè)整體,謂語(yǔ)一般用單數(shù)。例如:

  Three weeks was allowed for making the necessary preparations. 用三個(gè)星期來(lái)做準(zhǔn)備。

    Ten yuan is enough. 十元夠了。

5.指代意義決定謂語(yǔ)的單復(fù)數(shù)

1)代詞what, which, who, none, some, any, more, most, all等詞的單復(fù)數(shù)由其指代的詞的單復(fù)數(shù)決定。例如:

All is right. 一切順利。

All are present. 人都到齊了。

2)集體名詞作主語(yǔ)時(shí),謂語(yǔ)的數(shù)要根據(jù)主語(yǔ)的意思來(lái)決定。如family, audience, crew, crowd, class, company, committee等詞后,謂語(yǔ)動(dòng)詞用復(fù)數(shù)形式時(shí)強(qiáng)調(diào)這個(gè)集體中的各個(gè)成員,用單數(shù)時(shí)強(qiáng)調(diào)該集體的整體。例如:

   His family isn't very large. 他家成員不多。

   His family are music lovers. 他家個(gè)個(gè)都是音樂(lè)愛(ài)好者。

    但集合名詞people, police, cattle, poultry等在任何情況下都用復(fù)數(shù)形式。例如:

   Are there any police around? 附近有警察嗎?

3)有些名詞,如variety, number, population, proportion, majority 等有時(shí)看作單數(shù),有時(shí)看作復(fù)數(shù)。例如:

    A number of +名詞復(fù)數(shù)+復(fù)數(shù)動(dòng)詞。

    The number of +名詞復(fù)數(shù)+單數(shù)動(dòng)詞。

    A number of books have lent out.

    The majority of the students like English.

6.與后接名詞或代詞保持一致的情況

1)用half of, most of, none of, heaps of, lots of, plenty of 等引起主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞通常與of后面的名詞/代詞保持一致。例如:

    Most of his money is spent on books. 他大部分的錢(qián)化在書(shū)上了。

Most of the students are taking an active part in sports. 大部分學(xué)生積極參與體育運(yùn)動(dòng)。

2)用a portion of, a series of, a pile of, a panel of 等引起主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞通常用單數(shù)。例如: A series of accidents has been reported. 媒體報(bào)道了一連串的事故。

A pile of lots was set beside the hearth. 爐邊有一堆木柴。

3)如 many a 或 more than one 所修飾的短語(yǔ)作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞多用單數(shù)形式。但由more than… of 作主語(yǔ)時(shí),動(dòng)詞應(yīng)與其后的名詞或代詞保持一致。例如:

    Many a person has read the novel. 許多人讀過(guò)這本書(shū)。

    More than 60 percent of the students are from the city.百分之六十多的學(xué)生來(lái)自這個(gè)城市。

第2章  動(dòng)詞的時(shí)態(tài)

一. 概念:

時(shí)態(tài)是英語(yǔ)謂語(yǔ)動(dòng)詞的一種形式,表示動(dòng)作發(fā)生的時(shí)間和所處的狀態(tài).英語(yǔ)中的時(shí)態(tài)是通過(guò)動(dòng)詞形式本身的變化來(lái)實(shí)現(xiàn)的.英語(yǔ)有16種時(shí)態(tài),但中學(xué)階段較常用的有十種:一般現(xiàn)在時(shí),一般過(guò)去時(shí),一般將來(lái)時(shí),過(guò)去將來(lái)時(shí),現(xiàn)在進(jìn)行時(shí),過(guò)去進(jìn)行時(shí),將來(lái)進(jìn)行時(shí),過(guò)去完成時(shí),英在完成時(shí)和現(xiàn)在完成進(jìn)行時(shí).

二.相關(guān)知識(shí)點(diǎn)精講

1.一般現(xiàn)在時(shí)的用法

1) 經(jīng)常性或習(xí)慣性的動(dòng)作,常與表示頻腮度的時(shí)間狀語(yǔ)連用。時(shí)間狀語(yǔ): every…, sometimes, at…, on Sunday。例如:

   I leave home for school at 7 every morning. 每天早上我七點(diǎn)離開(kāi)家。

2) 客觀真理,客觀存在,科學(xué)事實(shí)。例如:

    The earth moves around the sun. 地球繞太陽(yáng)轉(zhuǎn)動(dòng)。

    Shanghai lies in the east of China. 上海位于中國(guó)東部。

3) 表示格言或警句。例如:

    Pride goes before a fall. 驕者必?cái) ?/p>

    注意:此用法如果出現(xiàn)在賓語(yǔ)從句中,即使主句是過(guò)去時(shí),從句謂語(yǔ)也要用一般現(xiàn)在時(shí)。

例:Columbus proved that the earth is round. 哥倫布證實(shí)了地球是圓的。

4) 現(xiàn)在時(shí)刻的狀態(tài)、能力、性格、個(gè)性。例如:

    I don't want so much. 我不要那么多。

    Ann writes good English but does not speak well. 安英語(yǔ)寫(xiě)得不錯(cuò),講的可不行。

比較:Now I put the sugar in the cup. 把糖放入杯子。

         I am doing my homework now. 我正在做功課。

  第一句用一般現(xiàn)在時(shí),用于操作演示或指導(dǎo)說(shuō)明的示范性動(dòng)作,表示言行的瞬間動(dòng)作。第二句中的now是進(jìn)行時(shí)的標(biāo)志,表示正在進(jìn)行的動(dòng)作的客觀狀況,所以后句用一般現(xiàn)在時(shí)。

2. 一般過(guò)去時(shí)的用法

1)在確定的過(guò)去時(shí)間里所發(fā)生的動(dòng)作或存在的狀態(tài)。例如:時(shí)間狀語(yǔ)有:yesterday, last week, an hour ago, the other day, in 1982等。例如:

   Where did you go just now? 剛才你上哪兒去了?

2)表示在過(guò)去一段時(shí)間內(nèi),經(jīng)常性或習(xí)慣性的動(dòng)作。例如:

   When I was a child, I often played football in the street. 我是個(gè)孩子的時(shí)候,常在馬路上踢足球。

Whenever the Browns went during their visit, they were given a warm welcome.

那時(shí),布朗一家無(wú)論什么時(shí)候去,都受到熱烈歡迎!    

3)句型:It is time for sb. to do sth  "到……時(shí)間了"  "該……了"。例如:It is time for you to go to bed.  你該睡覺(jué)了。

            It is time that sb. did sth. "時(shí)間已遲了"  "早該……了" ,例如It is time you went to bed.   你早該睡覺(jué)了。

           would (had) rather sb. did sth. 表示'寧愿某人做某事'。例如:I'd rather you came tomorrow.還是明天來(lái)吧。

4) wish, wonder, think, hope 等用過(guò)去時(shí),作試探性的詢問(wèn)、請(qǐng)求、建議等,而一般過(guò)去時(shí)表示的動(dòng)作或狀態(tài)都已成為過(guò)去,現(xiàn)已不復(fù)存在。例如:I thought you might have some. 我以為你想要一些。

比較:Christine was an invalid all her life.(含義:她已不在人間。)

        Christine has been an invalid all her life.(含義:她現(xiàn)在還活著)

        Mrs. Darby lived in Kentucky for seven years. (含義:達(dá)比太太已不再住在肯塔基州。)

        Mrs. Darby has lived in Kentucky for seven years. (含義:現(xiàn)在還住在肯塔基州,有可能指剛離去)

注意: 用過(guò)去時(shí)表示現(xiàn)在,表示委婉語(yǔ)氣。

1)動(dòng)詞want, hope, wonder, think, intend 等。例如:

    Did you want anything else? 您還要些什么嗎?

    I wondered if you could help me. 能不能幫我一下。

2)情態(tài)動(dòng)詞 could, would。例如:

    Could you lend me your bike? 你的自行車(chē),能借用一些嗎?

3.一般將來(lái)時(shí)

1) shall用于第一人稱,常被will 所代替。will 在陳述句中用于各人稱,在征求意見(jiàn)時(shí)常用于第二人稱。例如:

    Which paragraph shall I read first? 我先讀哪一段呢?

    Will you be at home at seven this evening? 今晚七點(diǎn)回家好嗎?

2) be going to +不定式,表示將來(lái)。

     a. 主語(yǔ)的意圖,即將做某事。例如:What are you going to do tomorrow? 明天打算作什么呢?

     b. 計(jì)劃,安排要發(fā)生的事。例如:The play is going to be produced next month。這出戲下月開(kāi)播。

     c. 有跡象要發(fā)生的事。例如:Look at the dark clouds, there is going to be a storm. 看那烏云,快要下雨了。

 3) be +不定式表將來(lái),按計(jì)劃或正式安排將發(fā)生的事。例如:

     We are to discuss the report next Saturday.我們下星期六討論這份報(bào)告。

4)  be about to +不定式,意為馬上做某事。例如:

     He is about to leave for Beijing. 他馬上要去北京。

  注意:be about to do 不能與tomorrow, next week 等表示明確將來(lái)時(shí)的時(shí)間狀語(yǔ)連用。

 4. 一般現(xiàn)在時(shí)表將來(lái)

1)下列動(dòng)詞come, go, arrive, leave, start, begin, return的一般現(xiàn)在時(shí)可以表示將來(lái),主要用來(lái)表示在時(shí)間上已確定或安排好的事情。例如:

   The train leaves at six tomorrow morning. 火車(chē)明天上午六點(diǎn)開(kāi)。

   When does the bus star? It stars in ten minutes. 汽車(chē)什么時(shí)候開(kāi)?十分鐘后。

2)以here, there等開(kāi)始的倒裝句,表示動(dòng)作正在進(jìn)行。例如:

    Here comes the bus. = The bus is coming. 車(chē)來(lái)了。

    There goes the bell. = The bell is ringing. 鈴響了。

3)在時(shí)間或條件句中。例如:

    When Bill comes (不是will come), ask him to wait for me. 比爾來(lái)后,讓他等我。

    I'll write to you as soon as I arrive there. 我到了那里,就寫(xiě)信給你。

4)在動(dòng)詞hope, take care that, make sure that等的賓語(yǔ)從句中。例如:

    I hope they have a nice time next week. 我希望他們下星期玩得開(kāi)心。

    Make sure that the windows are closed before you leave the room. 離開(kāi)房間前,務(wù)必把窗戶關(guān)了。

 5. 用現(xiàn)在進(jìn)行時(shí)表示將來(lái)

  下列動(dòng)詞come, go, arrive, leave, start, begin, return等現(xiàn)在進(jìn)行時(shí)可以表示將來(lái)。例如:

  I'm leaving tomorrow. 明天我要走了。

  Are you staying here till next week? 你會(huì)在這兒呆到下周嗎?

6. 現(xiàn)在完成時(shí)

  現(xiàn)在完成時(shí)用來(lái)表示之前已發(fā)生或完成的動(dòng)作或狀態(tài),其結(jié)果的影響現(xiàn)在還存在;也可表示持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)。其構(gòu)成:have (has) +過(guò)去分詞。

7. 比較一般過(guò)去時(shí)與現(xiàn)在完成時(shí)

1)一般過(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)一般過(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等,皆為具體的時(shí)間狀語(yǔ)。

共同的時(shí)間狀語(yǔ):this morning, tonight, this April, now, already, recently, lately 等。

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.。

      一般過(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。例如:

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)

第三章   動(dòng)詞的語(yǔ)態(tài)

一.概念:

   動(dòng)詞的語(yǔ)態(tài)是動(dòng)詞的一種形式,表示主語(yǔ)和謂語(yǔ)之間語(yǔ)法或語(yǔ)義的關(guān)系.英語(yǔ)的語(yǔ)態(tài)有兩種:主動(dòng)語(yǔ)態(tài)和被動(dòng)語(yǔ)態(tài).主動(dòng)語(yǔ)態(tài)用于主動(dòng)句,表示主語(yǔ)是動(dòng)作的執(zhí)行者.被動(dòng)語(yǔ)態(tài)用于被動(dòng)句,表示主語(yǔ)是動(dòng)作的承受者.主動(dòng)語(yǔ)態(tài)的構(gòu)成方式與動(dòng)詞時(shí)態(tài)相同,而被動(dòng)語(yǔ)態(tài)由 助動(dòng)詞be+過(guò)去分詞 構(gòu)成,有人稱,數(shù),時(shí)態(tài)的變化.

二. 相關(guān)知識(shí)點(diǎn)精講

1. let 的用法

 1)當(dāng)let后只有一個(gè)單音節(jié)動(dòng)詞,變被動(dòng)語(yǔ)態(tài)時(shí),可用不帶to 的不定式。例如:

They let the strange go.他們放陌生人走了。

---> The strange was let go.

 2)當(dāng)let 后賓補(bǔ)較長(zhǎng)時(shí),let 通常不用被動(dòng)語(yǔ)態(tài),而用allow或permit 代替。例如:

   The nurse let me go to see my classmate in the hospital. 那護(hù)士讓我去探望住院的同學(xué)。

   ----> I was allowed / permitted to see my classmate in the hospital.

2.短語(yǔ)動(dòng)詞的被動(dòng)語(yǔ)態(tài)

   短語(yǔ)動(dòng)詞是一個(gè)整體,不可丟掉后面的介詞或副詞。例如:

  My sister will be taken care of by Grandma. 我妹妹由奶奶照顧。

  Such a thing has never been heard of before. 這樣的事聞所未聞。

3. 表示"據(jù)說(shuō)"或"相信" 的詞組,基本上由believe, consider, declare, expect, feel , report, say, see, suppose, think, understand等組成。例如:

  It is said that…   據(jù)說(shuō)  

It is reported that… 據(jù)報(bào)道   

It is believed that… 大家相信     

It is hoped that… 大家希望

It is well known that… 眾所周知  

It is thought that… 大家認(rèn)為

It is suggested that… 據(jù)建議     

It is taken granted that…  被視為當(dāng)然 

It has been decided that… 大家決定  

It must be remember that… 務(wù)必記住的是

4. 不用被動(dòng)語(yǔ)態(tài)的情況

 1) 不及物動(dòng)詞或不及物動(dòng)詞短語(yǔ),如appear, die disappear, end(vi. 結(jié)束), fail, happen, last, lie, remain, sit, spread, stand, break out, come true, fall asleep, keep silence, lose heart, take place等沒(méi)有無(wú)被動(dòng)語(yǔ)態(tài)。例如:

   After the fire, very little remained of my house. 大火過(guò)后,我家燒得所剩無(wú)幾。

   比較:rise, fall, happen是不及物動(dòng)詞;raise, seat是及物動(dòng)詞。

  要想正確地使用被動(dòng)語(yǔ)態(tài),就須注意哪些動(dòng)詞是及物的,哪些是不及物的。特別是一詞多義的動(dòng)詞往往有兩種用法。解決這一問(wèn)題唯有在學(xué)習(xí)過(guò)程中多留意積累。

  2) 不能用于被動(dòng)語(yǔ)態(tài)的及物動(dòng)詞或動(dòng)詞短語(yǔ),如fit, have, hold, marry, own, wish, cost, notice, watch agree with, arrive at / in, shake hands with, succeed in, suffer from, happen to, take part in, walk into, belong to等。例如:

 This key just fits the lock. 這把鑰匙只配這把鎖。

     Your story agrees with what had already been heard. 你說(shuō)的與我們聽(tīng)說(shuō)的一致。

  3) 系動(dòng)詞無(wú)被動(dòng)語(yǔ)態(tài),如appear, be become, fall, feel, get, grow, keep, look, remain, seem, smell, sound, stay, taste, turn等。例如:It sounds good. 聽(tīng)上去不錯(cuò)。

  4) 帶同源賓語(yǔ)的及物動(dòng)詞如die/death, dream/dream, live/life等,以及反身代詞,相互代詞,不能用于被動(dòng)語(yǔ)態(tài)。例如:

She dreamed a bad dream last night. 她昨晚做了個(gè)惡夢(mèng)。

  5) 當(dāng)賓語(yǔ)是不定式時(shí),很少用于被動(dòng)語(yǔ)態(tài)。例如:

    (對(duì)) She likes to swim.

    (錯(cuò)) To swim is liked by her.

 5. 主動(dòng)形式表示被動(dòng)意義

 1)wash, clean, cook, iron, look, cut, sell, read, wear, feel, draw, write, sell等。例如:

   The book sells well.  這本書(shū)銷路好。

   This knife cuts easily.  這刀子很好用。

 2)blame, let(出租), remain, keep, rent, build等。例如:

   I was to blame for the accident. 事故發(fā)生了,我該受指責(zé)。

   Much work remains. 還有許多活要干。

 3) 在need, require, want, worth (形容詞), deserve后的動(dòng)名詞必須用主動(dòng)形式。例如:

   The door needs repairing.= The door needs to be repaired. 門(mén)該修了。

   This book is worth reading. 這本書(shū)值得一讀。

4)特殊結(jié)構(gòu):make sb. heard / understood (使別人能聽(tīng)見(jiàn)/理解自己)等。例如:

     Explain it clearly and make yourself understood. 解釋清楚些,讓別人理解你的話。

6. 被動(dòng)形式表示主動(dòng)意義,如 be determined, be pleased, be graduated (from), be prepared (for), be occupied (in), get married等。例如:

  He is graduated from a famous university. 他畢業(yè)于一所有名的大學(xué)。

  注意:表示同某人結(jié)婚,用marry sb. 或get married to sb.均可。例如:

  He married a rich girl. 他與一個(gè)富妞結(jié)婚了。

  He got married to a rich girl.

7.need/want/require/worth

  當(dāng) need, want, require, be worth后面接doing時(shí),表示的是被動(dòng)意義。例如:

    Your hair wants cutting. 你的頭發(fā)該理了。

    The floor requires washing. 地板需要沖洗。

二.相關(guān)知識(shí)點(diǎn)精講

1.辨別if 引導(dǎo)真實(shí)條件句和if引導(dǎo)的虛擬條件句的區(qū)別

If he has time, he will go with us.= Probably he has time and will go with us.

If he had time, he would go with us.=But in fact he has no time.

2.虛擬條件句中主句和從句的謂與動(dòng)詞構(gòu)成形式如下表

 

if條件句中的謂與動(dòng)詞

主句的謂與動(dòng)詞

與現(xiàn)在的事實(shí)相反

 

1. 行為動(dòng)詞用did 形式

2. be動(dòng)詞用were

should

would

could   + 動(dòng)詞原形

might

與過(guò)去的事實(shí)相反

 

had + done

3.混合時(shí)間的虛擬語(yǔ)氣

如果條件句中的動(dòng)作和主句的動(dòng)作不是同時(shí)發(fā)生,主句和從句的謂語(yǔ)動(dòng)詞的形式應(yīng)分別根據(jù)各自所表示的時(shí)間加以調(diào)整。

1)0If I had received the passport yesterday, I would start today.

2)If he had telephoned me last night, I would see him now.

3)If he had followed the doctor’s advice, he would be all right now.

4)If China had not been liberated, the working people would still be leading a miserable life.

4.should/ could / might/ ought to + have done 表示“過(guò)去本應(yīng)該/可以做而實(shí)際上卻沒(méi)做”

needn’t have done 表示“過(guò)去沒(méi)必要作而實(shí)際上做了”

5.虛擬語(yǔ)氣中的倒裝句

如果虛擬語(yǔ)氣的條件從句謂語(yǔ)動(dòng)詞中含有were, had, could, should,有時(shí)可將if省去,而將條件從句的主語(yǔ)置于were, had, should, could 之后。

Had you invited us, we would have come to your party.

Were I you, I would do more practice after class.

Could she lend us a helping hand, she would do so.

6.wish 后面的賓語(yǔ)從句的謂語(yǔ)動(dòng)詞應(yīng)使用虛擬語(yǔ)氣, 表示“可惜…;….就好了; 悔不該…; 但愿…。”

主句謂語(yǔ)

從句謂語(yǔ)

wish

時(shí)態(tài)

謂語(yǔ)動(dòng)詞的形式

現(xiàn)在時(shí)

表示與wish同時(shí)發(fā)生

動(dòng)詞用過(guò)去時(shí)

be動(dòng)詞用were

過(guò)去時(shí)

表示在wish之前發(fā)生的動(dòng)作

動(dòng)詞用had done

be用had been

將來(lái)時(shí)

表示在wish之后發(fā)生的動(dòng)作

動(dòng)詞用would do; should do

be 用 would be ; should be

1)I wish I knew the key to the answer.

2)I wish I were ten years younger.

3)I wish that I had gone to the football match last week.

4)I wish that you had been here yesterday.

5)He wishes that we would visit the old school.

7.表示命令或建議動(dòng)詞suggest, insist, propose, desire, demand, request, order, command 后的賓語(yǔ)從句中應(yīng)使用虛擬 should +動(dòng)詞原形; should 不可用would 來(lái)替代; 主句所使用的動(dòng)詞時(shí)態(tài)不限。

8.suggest 為“建議去做…; 命令…”從句用should + do

為“ 說(shuō)明; 暗示”, 從句用過(guò)去時(shí)或過(guò)去完成時(shí)。

1) The doctor suggested that I should take the medicine three times a day.

2) The doctor suggested that my grandmother had caught a bad cold.

9.insist “堅(jiān)持要去做…,堅(jiān)持應(yīng)該去做”,從句用should + do為“堅(jiān)持表明,堅(jiān)持說(shuō)/解釋”, 從句用過(guò)去時(shí)或過(guò)去完成時(shí)。

10.虛擬語(yǔ)氣也用于表語(yǔ)從句和主語(yǔ)從句中,表示間接的命令、要求、請(qǐng)求、建議、決定等,主句的主語(yǔ)通常是suggestion, proposal, request, order, idea 等。表語(yǔ)從句中的謂語(yǔ)動(dòng)詞是should +動(dòng)詞原型,should 可以省略。

11.在主語(yǔ)從句中,當(dāng)從句用來(lái)表示驚奇、不相信、惋惜等,從句的謂語(yǔ)動(dòng)詞用需擬語(yǔ)氣形式。其謂語(yǔ)動(dòng)詞時(shí)should + 動(dòng)詞原型, 或should 省略。

第5章  助動(dòng)詞

一.概念:

   助動(dòng)詞是幫助主要?jiǎng)釉~構(gòu)成各種時(shí)態(tài),語(yǔ)態(tài),語(yǔ)氣以及否定或疑問(wèn)結(jié)構(gòu)的動(dòng)詞.助動(dòng)詞分為時(shí)態(tài)助動(dòng)詞和結(jié)構(gòu)助動(dòng)詞兩種.

二.相關(guān)知識(shí)點(diǎn)精講:

  1. 助動(dòng)詞be的用法

1) be +現(xiàn)在分詞,構(gòu)成進(jìn)行時(shí)態(tài)。例如:

They are having a meeting. 他們正在開(kāi)會(huì)。

English is becoming more and more important. 英語(yǔ)現(xiàn)在越來(lái)越重要。

2) be + 過(guò)去分詞,構(gòu)成被動(dòng)語(yǔ)態(tài)。例如:

The window was broken by Tom.. 窗戶是湯姆打碎的。

English is taught throughout the world. 世界各地都教英語(yǔ)。

3) be + 動(dòng)詞不定式,可表示下列內(nèi)容:

     a. 表示最近、未來(lái)的計(jì)劃或安排。例如:

    He is to go to New York next week.. 他下周要去紐約。

    We are to teach the freshmen. 我們要教新生。

    說(shuō)明: 這種用法也可以說(shuō)成是一種將來(lái)時(shí)態(tài)表達(dá)法。

     b. 表示命令。例如:

    You are to explain this. 對(duì)此你要做出解釋。

3) 構(gòu)成否定祈使句。例如:

    Don't go there. 不要去那里。

    Don't be so absent-minded. 不要這么心不在焉。

說(shuō)明: 構(gòu)成否定祈使句只用do,不用did和does。

4)放在動(dòng)詞原形前,加強(qiáng)該動(dòng)詞的語(yǔ)氣。例如:

    Do come to my birthday party. 一定來(lái)參加我的生日宴會(huì)。

高考數(shù)學(xué)第一輪復(fù)習(xí)--歸納―猜想―證明

 

(一)知識(shí)歸納:

由事物的部分特殊事例猜想出事物的一般結(jié)論,這種方法人們稱為“不完全歸納法”,用不完全歸納法得出的結(jié)論需要經(jīng)過(guò)證明,因此全部過(guò)程可以小結(jié)為下面程序:

①計(jì)算命題取特殊值時(shí)的結(jié)論;②對(duì)這些結(jié)果進(jìn)行分析,探索數(shù)據(jù)的變化規(guī)律,并猜想命題的一般結(jié)論;③證明所猜想的結(jié)論.

(二)學(xué)習(xí)要點(diǎn):

在中學(xué)數(shù)學(xué)內(nèi),“歸納―猜想―證明”的推理方法一般只局限于數(shù)列的內(nèi)容,而且與正整數(shù)n有關(guān),其它內(nèi)容中很少有要求,解決問(wèn)題時(shí)要注意以下幾點(diǎn),①計(jì)算特例時(shí),不僅僅是簡(jiǎn)單的算數(shù)過(guò)程,有時(shí)要通過(guò)計(jì)算過(guò)程發(fā)現(xiàn)數(shù)據(jù)的變化規(guī)律;②猜想必須準(zhǔn)確,絕對(duì)不能猜錯(cuò),否則將徒勞無(wú)功;③如果猜想出來(lái)的結(jié)論與正整數(shù)n有關(guān),一般用數(shù)學(xué)歸納法證明.

【例1已知數(shù)列滿足關(guān)系式N+),

(Ⅰ)用a表法a2a3,a4

(Ⅱ)猜想an的表達(dá)式(用a和n表示),并證明你的結(jié)論.

[解析](Ⅰ)

(Ⅱ)()  猜想下面用數(shù)學(xué)歸納法證明:

1°.當(dāng)n=1時(shí),當(dāng)n=1結(jié)論正確;

2°.假設(shè)當(dāng)n=k時(shí)結(jié)論正確,即,

∴當(dāng)n=k+1時(shí) 

=當(dāng)n=k+1時(shí)結(jié)論也正確;

根據(jù)1°與2°命題對(duì)一切n∈N*都正確.

[評(píng)析]“歸納―猜想―證明”是解決數(shù)列的某些問(wèn)題的一種重要方法,對(duì)于一些變換技巧比較高的問(wèn)題,如果能通過(guò)這種方法解答成功,則解答過(guò)程比較其它方法更容易.

【例2已知數(shù)列滿足:計(jì)算a2a3,a4的值,由此歸納出an的公式,并證明你的結(jié)論.

[解析]很容易算出a2=5,a3=16,a4=44,但由此猜想出結(jié)論顯然是非常困難的,下面作一些探索.

a2=2 a1+3×2°=2×1+3×2°,

a3=2(2×1+3×2°)+3×21=22×1+2×3×21,

a4=2(22×1+2×3×21)+3×22=23×1+3×3×22

猜想an=2n-1+(n-1)×3×2n-2=2n-2(3n-1);

用數(shù)學(xué)歸納法證明:

1°.當(dāng)n=1時(shí),a1=2-1×=1,結(jié)論正確;

2°.假設(shè)n=k時(shí),ak=2k-2(3k-1)正確,

∴當(dāng)n=k+1時(shí), =

結(jié)論正確;

由1°、2°知對(duì)n∈N*

[評(píng)析]如果計(jì)算出來(lái)的數(shù)據(jù)很難猜出結(jié)論時(shí),應(yīng)考慮整理計(jì)算過(guò)程,探索數(shù)據(jù)的變化規(guī)律,看看能否猜想成功.

3】已知等差數(shù)列中,a2=8,前10項(xiàng)的和S10=185,

(Ⅰ)求數(shù)列的通項(xiàng)公式an;

(Ⅱ)若從數(shù)列中依次取出第2,4,8,…,2n,…項(xiàng),按原來(lái)的順序排成一個(gè)新數(shù)列,試求新數(shù)列的前n項(xiàng)和An;

(Ⅲ)設(shè) Bn=n(5+3 an),試比較An和Bn的大小,并說(shuō)明理由.

[解析](Ⅰ)設(shè)公差為d,∴

(Ⅱ)設(shè)新數(shù)列為,∴ 

∴An=3×(2+22+23+…+2n)+2n=3×2n+1+2n-6;

(Ⅲ)∵

A4=3×32+2=98,A5=3×64+4=196,A6=3×128+6=390,A7=3×256+8=776,……

而B(niǎo)1=20,B2=58,B3=114,B4=188,B5=280,B6=390,B7=518,……

①當(dāng)n=1,2,3,4,5時(shí),Bn>An;

②當(dāng)n=6時(shí),B6=A6

③當(dāng)n≥7,且n∈N*時(shí),猜想An>Bn,用數(shù)學(xué)歸納法證明:

1°.當(dāng)n=7時(shí),A7=766>518=B7,結(jié)論正確;

2°.假設(shè)當(dāng)n=k(k≥7)時(shí),Ak>Bk,即3×2k+1+2k-6>9k2+11k2k+1>3k2+3k+2,

∴n=k+1時(shí),

=6×2 k+2-9k2-27k-24

=6×[2 k+1-(3k2+3k+2)]+6×(3k2+3k+2)-9k2-27k-24

=6×[2 k+1-(3k2+3k+2)]+9k2-9k-12

>9k2-9k-12=9k(k-1)-12≥9×7×(7-1)-12>0

∴Ak+1>Bk+1,即n=k+1時(shí),結(jié)論也正確;

根據(jù)1°、2°知當(dāng)n≥7且n∈N*時(shí),有An>Bn.

[評(píng)析]從上面例子可以看出,歸納猜想不僅僅是要有對(duì)數(shù)據(jù)的觀察能力,還需要有一定的經(jīng)驗(yàn),否則很難作出上述準(zhǔn)確的猜想.

4】已知數(shù)列滿足:問(wèn)是否存在常數(shù)p、q,使得對(duì)一切n∈N*都有并說(shuō)明理由.

[解析]設(shè)存在這樣的常數(shù)p、q,

由此猜想,對(duì)n∈N*,有

下面用數(shù)學(xué)歸納法證明這個(gè)結(jié)論:

1°.當(dāng)n=1時(shí),,結(jié)論正確;

2°.假設(shè)當(dāng)n=k時(shí)結(jié)論正確,即  ∴當(dāng)n=k+1時(shí),

∴當(dāng)n=k+1時(shí)結(jié)論正確,故當(dāng)n∈N*時(shí),成立.

[評(píng)析]例4是一類探索題型,由條件直接推出結(jié)論是非常困難的,通過(guò)歸納―猜想―證明的方法,難度不大.
