1.as…as…常構(gòu)成一些詞組：as soon as…(一旦…就…), as well as…(同樣), as+形容詞/副詞+as possible(盡可能……地)。如：Please ring me up as soon as you get to Beijing.(請你一到北京就給我寫信。)/ Miss Gao hurried to the school gate as quickly as possible.(高小姐盡快地趕到了校門口。)

[注釋] "as long / much as + 名詞"可以表示"長達(dá)/多達(dá)…"的含義。如：The house costs as much as five hundred thousand yuan.(那幢房子花費(fèi)高達(dá)50萬元。)/ They stayed in the cave(山洞)as long as two weeks.(他們呆在山洞里長達(dá)兩周。)

2. later、after、ago、before的用法：①"一段時(shí)間+later/ago"分別表示"(多久)以后/以前",主要用于過去時(shí)態(tài)。②"after/before+某個(gè)時(shí)刻"分別表示"在某時(shí)刻之后/之前",此時(shí)兩個(gè)詞是介詞。③ago與before：ago只能用于過去時(shí),before用于完成時(shí)。如：He had an accident a week ago.(一周前出了一個(gè)事故)/ Some years later, the boy became a very famous singer.(數(shù)年后這個(gè)男孩成了著名的歌唱家)/ Have you been there before?(你從前到過那兒嗎?)/ After a few years he gave up smoking.(過了幾年他戒了煙。)

Nor did I.(他沒有看足球賽,我也沒有。)/ You can also find the market is very good.(你還可以發(fā)覺那個(gè)市場很好。)

5. enough、too、so、very、quite、very much的用法： enough ("足夠,十分")放在形容詞或副詞之后;too("太")、very("非常")、quite("相當(dāng)")、so("如此地")等放在形容詞或副詞之前,very much("非常")放在動詞之后。如：It's too/so/very/quite expensive.(它太貴/那么貴/非常貴/相當(dāng)貴。)/ I don't like sweets very much.(我不很喜歡糖果)

[注意] very與 much的區(qū)別：very修飾形容詞、副詞的原級和現(xiàn)在分詞形容詞,much修飾形容詞和副詞的比較級;much還可以修飾疑問句和否定句中的動詞,very不可以。如：He is very stupid.(他很笨)/ The film was very moving and everyone swept.(電影非常動人,大家都哭了)/ You must work much harder or you will fail to enter the good school.(你得學(xué)習(xí)更努力,不然你考不進(jìn)那所好學(xué)校)/ I don't like him much.(我不太喜歡他)

10. like...very much、like...better(=prefer)、like...best的用法：三個(gè)短語分別表示"非常喜歡"、"更喜歡"、"最喜歡"。如：I like baseball very much.(我非常喜歡棒球)/ Do you like butter better than cheese?( / They like hamburgers best.

11."quite/what+a+形容詞+名詞"的用法：記�。孩賟uite/such/what...+a+形容詞+名詞;②too/so/how+形容詞+a+名詞;③rather+a+形容詞+名詞 = a+ rather+形容詞+名詞。如：I have never seen such a strange guy(家伙).(我從未見過這樣奇怪的家伙) / It is quite a nice day for a walk.(這真是散步的好日子)

12. how 的幾個(gè)短語：how often"多常,每隔多久",用于一般時(shí)態(tài),對表示頻度的詞語進(jìn)行提問; how soon"多久以后",用于將來時(shí)態(tài); how long"多久",用于過去時(shí)、完成時(shí)或其他時(shí)態(tài); how many times"多少次",用于過去時(shí)或完成時(shí),對總計(jì)次數(shù)進(jìn)行提問; how much"多么,多少",對程度進(jìn)行提問,也可以對數(shù)量(不可數(shù))或金錢進(jìn)行提問。如：How long have you been like this?(你這樣已經(jīng)多久了?)/ How often does he wash his face?(他每隔多久洗一次臉?)

13. much、more與most的用法：這三個(gè)詞除了是形容詞作名詞的修飾語之外,還是程度副詞,much表示"很",修飾原級形/副,more表示"更"用來構(gòu)成多音節(jié)形/副的比較級,most表示"最"用來構(gòu)成多音節(jié)形/副的最高級。此外,much也可以修飾比較級形/副。如：This park is much more beautiful than that one.(這個(gè)公園比那個(gè)漂亮多了)/ It is the most instructive film I have ever seen.(這是我看過的最有教育意義的電影)

16.too...to...與so...that...的問題：副詞too/so后面跟形容詞或副詞,to后面跟動詞,that后面跟從句。Too...to... ("太.……以致不……")是否定的結(jié)構(gòu),用于簡單句;so...that...("如此…以致…")是肯定結(jié)構(gòu),用于復(fù)合句。如：The child is too young to join the army.(這孩子年齡太小還不能參軍)/ He is so strong that he can lift the heavy box.(他這么強(qiáng)壯,搬得動那個(gè)重箱子。)

18. farther與further的用法區(qū)別：表示地點(diǎn)、方向或距離時(shí)兩個(gè)詞同義,意思為"更遠(yuǎn)、較遠(yuǎn)",但是further還表示"更多、進(jìn)一步、額外"等意思,此時(shí)不能換為farther. 如：They decided to go farther/further the next day.(他們決定第二天走得再遠(yuǎn)些)/ This problem will be further discussed.(這個(gè)問題還要進(jìn)一步討論)/ Every one of them had their further studies after they left college.(他們每個(gè)人大學(xué)畢業(yè)后繼續(xù)進(jìn)修)

19. rather與quite的用法區(qū)別：同very一樣,兩個(gè)詞都表示形容詞或副詞的程度,quite表示"不到最高程度但是比預(yù)料的好",rather比quite更接近very的含義,含有令人驚訝的意思。見下圖對"nice"程度的描繪：

not nice (fairly) nice quite nice rather nice very nice

如：It's quite a nice film.(這是部好片子)。(可能意味著不是一部最好的電影) / It's rather a nice film.(這是部很不錯的電影。)(意味著比大多數(shù)電影都好)

[注意]注意quite與rather后面的次序詞序。

20. maybe、possibly、perhaps的區(qū)別：maybe"可能、也許",比另外兩個(gè)詞更不正式、更隨便、可能性不大;possibly"可能地、或者、也許",可能性較大,在否定句和疑問句中表示"無論如何";perhaps"可能",較為常用而且正式,可能性也不大。如：You could put it over there,maybe.(也許你可以把它放在那邊) / I couldn't possibly have finished such a long book in such a short time.(我不可能在這么短的時(shí)間內(nèi)完成這么長的一本書)/ I thought perhaps it was the letter you have been expecting.(我以為那也許就是你期盼的信件)

21. most、mostly的區(qū)別：most作為形容詞和名詞時(shí)意思是"大多數(shù)的、大部分的",作為副詞時(shí)意思為"最,十分、很";mostly僅為副詞,意思為"主要地、多半地、大部分地"。如：I was at home most of the time when I was free.(我有空時(shí)大部分時(shí)間都在家)Most children are naughty.(大部分的孩子都淘氣)/ This is the most exciting part of the film.(這是電影中最令人興奮的部分)/She is mostly out on Sundays.(星期天她一般不在家)

22. (be) worth、(be) worthy of的區(qū)別：worth一般被看作是介詞,后面接名詞或者動名詞,用主動表示被動含義,還可以用副詞well修飾;worthy of表示"值得的、配得上的",后面跟動名詞的被動形式。如：What is worth doing at all is worth doing well(凡是值得做的,就值得好好去做). / The house is worth ￥300,000.(房子價(jià)值30萬元)/ This book is well worth reading several times.(這本書值得好好讀幾遍)/ It is a thing worthy of being seen.(這是一個(gè)值得看的東西)

23.almost、nearly的區(qū)別：兩個(gè)詞意思相近,都表示"幾乎、將近",大多數(shù)情況下可以互換,與否定詞連用時(shí)用almost不用nearly. almost no 相當(dāng)于hardly any(幾乎沒有)。如：He had done almost nothing today.(他今天幾乎沒有干什么) / We are almost/nearly there.(我們幾乎就到那里了)/ Almost nobody/Hardly anybody understood his words.(幾乎沒有人懂他的話)

24.a bit與a little的區(qū)別：這兩個(gè)名詞短語經(jīng)常當(dāng)作副詞使用,修飾形容詞或副詞的原級或比較級,可以互換,語氣比rather弱。如：This digital camera is a bit(a little) expensive.(這臺數(shù)碼相機(jī)有點(diǎn)貴)/ It is a little(a bit) colder than yesterday.(今天比昨天冷了點(diǎn))

另外,a little可以直接加不可數(shù)名詞,a bit 則采用"a bit + of +名詞(不可數(shù)或可數(shù)名詞復(fù)數(shù))"的形式。如：I have got a bit of a cold.(我有點(diǎn)感冒)/ Go and get a little water for me, please.(請你去給我搞點(diǎn)水來)

[注意] not a bit(=not at all)意為"根本不",而 not a little則意為"非常,不是一點(diǎn)"。
