        發(fā)布時間:2016-3-11 編輯:互聯(lián)網(wǎng) 手機(jī)版

        1.介詞between和among的用法及區(qū)別

        1)between(prep)“在(兩者)之間”;一般只指在兩者或兩部分之間。例如:

        ①There is a profound and lasting friendship between China and Korea.

        中朝兩國之間有深厚和永恒的友誼。

        ②The Yalu River flows between China and Korea.

        鴨綠江介于中朝兩國之間。

        【注意】偶爾between也可用來指三個或三個以上之間,這種情況實際上

        仍是指其中一個和其他中間的一個之間的關(guān)系。如:

        ③Laos lies between China, Burma, Thailand, Cambodia and Vietnam.

        老撾位于中國、緬甸、泰國、柬埔寨和越南之間。 ④The friendly relations between the peoples are profound and lasting.

        各族人民之間的友好關(guān)系是深厚的和永恒的。

        2)among(prep)“在……中間”;表示在三個或三個以上的人或物中間,后面通常接集體名詞或可數(shù)名詞復(fù)數(shù)形式。例如:

        ①I saw him among the crowd. 我看見他在人群中。

        ② He came from a village among the hills. 他來自群山中的一個村莊。

        2.while[wail]的用法

        1)while可以用作并列連詞,表示對比意義,譯為“而”,“卻”。例如:

        ①Instead, he asked his father why he was not able to hatch chickens, while hens could. 他反而問他父親為什么他不能孵小雞,而母雞卻能。

        ②Jane was dressed in blue, while Mary dressed in red.

        珍妮穿藍(lán)色衣服,而瑪麗卻穿紅色衣服。

        2)while還可以用作從屬連詞,作“在……期間”,“當(dāng)……時候”講,使用時應(yīng)注意它與用作從屬連詞的when的區(qū)別:

        when引導(dǎo)的時間狀語從句,即可表示“一段時間”,又可表示“一點時間”,因此從句的謂語動詞既可以是延續(xù)性的,也可以是非延續(xù)性的。如:

        ①I hope to see you when(while)I stay in Beijing on business.

        (一段時間)當(dāng)我出差北京時,希望見到你。

        ②When the clock struck twelve, all the lights went out.

        (一點時間)當(dāng)鐘敲響十二下時,燈全部熄滅了。

        【注意】while引導(dǎo)的時間狀語從句只能表示“一段時間”所以 while從句的謂語動詞應(yīng)是延續(xù)性動詞(或狀態(tài)動詞)。例如:

        ①While I stayed(or was) in Shanghai, I saw her three times.

        我在上海期間見到她三次。

        如果從句的謂語動詞是延續(xù)性的,可以用while也可以用when。例

        如:

        ②While(When) we were having a meeting, a stranger came in.

        我們在開會時,一個陌生人走了進(jìn)來。

        3.still, yet和already的用法比較

        1)still表示某事仍在進(jìn)行中,意為“仍然”,“還”。例如:

        ①I am still busy, I have not finished my work yet.

        我仍然很忙,我沒有干完這個活兒。

        ②How to take some useful things out of the waste materials and use them again is still a big problem. 怎樣從廢料中提取有用的東西并加以重新利用

        仍然是個大問題。

        2)yet作“已經(jīng)”解時,通常用于疑問句或否定句;作“還,仍然”解時,與not 連用,表示還沒有。

        3)already的意思是“已經(jīng)”,通常用于肯定句。例如:

        ①They have already made full use of the waste water.

        他們已經(jīng)充分利用了廢水。

        4.助動詞do的用法

        在肯定句中,為了避免重復(fù)出現(xiàn)前面已經(jīng)用過的某個動詞時,通常用

        助動詞do。例如:

        ①It's important to listen to people carefully, and I usually do.

        仔細(xì)傾聽別人的意見是重要的,我通常也是這樣做的。

        5.over和across和區(qū)別

        1)over和across都可用來表示“向(或在)某一長形物體如街道、馬路、河流的另一邊!

        ①We walked over/across the road. 我們走過馬路。

        ②He lives just over/across the river? 他就住在河對面。

        【注意】over可用于水面上動作,不能用于水中動作。

        ③How long will it take to swim across the river?

        游過這條河需要多久。(不能用over)。

        2)over和across都可用來表示“在某一高形物體的另一邊”,表示狀態(tài)。

        ④If we can be over/across the mountain before sunrise, there will be hope to win. 如果日出前我們能翻過那座山,就有希望獲勝。

        【注意】表示“越過”某一高形物體,用over與動詞搭配,不用across。

        ⑤When I saw him, he was climbing over the fence.

        我看到他時,他正翻過圍墻。(不用across)

        3)across可用來表示從某一范圍的一邊到另一邊,如田野、沙漠、房間等。

        ⑥It took him six weeks to walk across the desert.

        他花了六個星期走過沙漠。(不用over)

        ⑦He walked across the room, smiling strangely.

        他走到房間的另一邊,臉上掛著令人捉摸不透的微笑。(不用over)

        6.however的用法

        作副詞時可放在句首,句中或句尾,但是要用逗號隔開。在句首時逗號與在它后面,在句尾時逗號在其前面,在句中時,其前后均用逗號隔開。

        與but的區(qū)別是:but語氣不如however強(qiáng),且不需要加逗號隔開。例如:

        ①It's raining hard. However, I think we should go to school on time. 雨下得很大,但我認(rèn)為我們?nèi)匀灰磿r去上學(xué)。

        ②She waited, however, for no answer.

        她仍在等,盡管沒有回音。

        ③The students thought they had done everything as the teacher did. They were mistaken, however. 學(xué)生們認(rèn)為他們已經(jīng)按老師的要求做到了,然而他們錯了。

        重要詞組短語

        1.in English意為“使用英語”,in表示“用某種語言”。例如:

        ②Can you speak in Japanese? 你可以用日語講話嗎?

        ②This article was written in American English.

        這篇文章是用美國英語寫成的。

        2.written English意為“書面英語”;spoken English意為“口語英語”;Englishspeaking country意為“講英語的國家”;spelling differences意為“拼寫差異”。例如:

        4.for example與such as的用法及區(qū)別

        1)for example和such as都可當(dāng)作“例如”解。但such as用來列舉事物,插在被列舉事物與前面的名詞之間。例如:

        ①The farm grows various kinds of crops, such as wheat, corn, cotton and rice.

        這個農(nóng)場種植各種各樣的莊稼,例如麥子,玉米,棉花和稻米。

        【注意】

        (1)such as一般不宜與and so on連用。

        (2)對前面的復(fù)數(shù)名詞部分起列舉作用,一般不全部列出。故不可以說:

        He knows four languages, such as Chinese, English, French and German. 應(yīng)將such as改成namely, 后面加逗號。即:He knows four languages, namely, Chinese, English, French and German.

        2)for example意為用來舉例說明,有時可作為獨立語,插在句中,不影響句子其他部分的語法關(guān)系。例如:

        ①A lot of people here, for example, Mr John, would rather have coffee.

        這兒的許多人,例如約翰先生,寧愿喝咖啡。

        5.由come構(gòu)成的重要短語

        6.a(chǎn) great many等表示“許多”的詞語

        英語中有許多詞語可用來表示“許多”,根據(jù)性質(zhì)可分為三大類。

        1)修飾可數(shù)名詞復(fù)數(shù)形式的有 many, a good/great many, quite a few, a large (或great)/small number of等,其后的謂語動詞用復(fù)數(shù)形式。如:

        ①A great/good many words and expressions have come into the language from American English. 美國英語中的許多單詞和短語進(jìn)入了這門語言。

        ②Many have come to visit the old temple. 許多人來是為了看看古廟。

        ③Quite a few people didn't understand this. Very few would accept it.

        有許多人不明白這一點。很少有人愿意接受。

        ④A great/small number of new factories have been set up in my hometown.

        我們家鄉(xiāng)建立了許多新的工廠。

        ▲many和few, a few在句中可作定語、主語,但不能作表語。如只能說I have many/few books, 而不能說 My books are many/few.

        ▲very many相當(dāng)于a great/good many, 在程度上比many要強(qiáng)。

        ▲a number of修飾主語時,謂語動詞用復(fù)數(shù)形式,the number of…作主語時,謂語動詞用單數(shù)。如:

        ⑤A number of students have done the work well. 許多學(xué)生作業(yè)做得很好。

        ⑥The number of the students in our school has risen this year.

        今年我們學(xué)校學(xué)生的數(shù)量上升了。

        句⑤的 A number of作定語修飾主語 students。句⑥的介語短語 of the students in our school作定語,修飾前面的主語 the number, 表示特指,students 前的冠詞the不能省。

        2)修飾不可數(shù)名詞的有much, a great deal of, quite a little, an amount of等。其后的謂語動詞用單數(shù)形式。如:

        ①He has spent much/quite a little/a great deal of/a large amount of money on his new house. 他在新房子上花費了許多錢。

        ②Much/A great deal/Quite a little has been done to stop the noise.

        已采取了許多措施來制止污染。

        ▲much, a great deal和 many一樣,可作定語或主語,而不能作表語,我們一般說 He has much/a great deal of money, 而不說 His money is much(或a great deal)。

        ▲a great deal后面不接名詞時,不能用介詞of。

        3)既能修飾可數(shù)名詞,又能修飾不可數(shù)名詞的有 a lot of, lots of, plenty of, a great quantity of等,謂語動詞根據(jù)主語是可數(shù)或不可數(shù)決定單復(fù)數(shù)形式。如: ①There are a lot of/lots of people in that room. 那個房間里有許多人。

        ②There's a lot of/lots of rice in the bag. 那只口袋里有許多大米。

        ③They don't have plenty of(=enough)rooms to live in/food to eat.

        他們沒有足夠的房間住/沒有足夠的食品吃。

        常用句型結(jié)構(gòu)

        1.“主語+ have +(修飾語:no, little, some, much, great)等+difficulty/trouble +in + doing sth.”是一個常用的句型。例如:

        ①Everyone in the town knew him so we had no trouble/difficulty in finding his house. 鎮(zhèn)上誰都認(rèn)識他,因而我們毫不費事地找到了他的家。 ②We had great difficulty in building the house. 我們建房子費了很大勁。

        ③The students had some trouble in answering the question.

        同學(xué)們回答這個問題有些困難。

        ④Do you have any trouble in finishing the work within two days?

        兩天內(nèi)你完成這項工作有困難嗎?

        【注意】在使用這一句型時應(yīng)注意以下四點:

        1)difficulty/trouble為不可數(shù)名詞,意為“困難”。

        2)修飾語主要有no, little, some, much, great等。

        3)句中介詞為in,有時可省略。

        4)介詞in后必須跟動詞的-ing形式。 2.I'd like to do something.是一個表示“愿意做某事”的常用句型。使用這一句型,應(yīng)注意:

        1)'d like是 should like和 would like的縮略式。常用來表示“愿意”之意,尤其是禮貌地提出邀請或愿意提供幫助時。like后可接名詞或帶to的動詞不定式,但不接動詞-ing形式。如:

        ①Would you like some bananas? 你想吃香蕉嗎?

        ②Would you like to go there with me tomorrow?

        明天你愿意和我一起去那兒嗎?

        【注意】用這種邀請句時,肯定回答用:“Yes, I'd love to.”否定回答用:

        “I'd love to, but…”

        ③I'd like to see your ten-speed bicycle. 我想看看你們的十速自行車。

        ④Would you like to go to see the film this evening?

        今天晚上你愿意去看電影嗎?

        ⑤I'd love to, but I have a lot of work to do.

        我愿意去,但是我有很多事要做。

        2)除would, should外,had也?s寫成'd形式。例如:

        ①You'd better put on your coat. It's rather cold outside. (had的縮略式)

        你最好穿上大衣,外面很冷的。

        ②He'd rather die than give up his beautiful wife.

        他寧死也不放棄他漂亮的妻子。(would的縮略式)

        【注意】would rather do something或would like to do something均表示主語的意愿,而had better do something則表示說話者的意愿。
