暑假過后，新初三生們迎來了初中最重要的一年——初三。為方便2013年中考考生及家長查詢相關(guān)信息，出國留學(xué)網(wǎng)中考頻道特別搜集匯總了中考英語知識(shí)點(diǎn)以供參考：
§46 as soon as/ as early as/ as quickly as
Ⅰ. 這三個(gè)詞都有“盡快、盡早”之意。
Ⅱ. as soon as 側(cè)重于“極短時(shí)間內(nèi)”。還表示“一……就……”之意，引導(dǎo)狀語從句。如：
① I’ll return it as soon as I can.我將盡快地把它還給你。
Ⅲ. as early as 側(cè)重于一天中的早晨或在限定的時(shí)間內(nèi)再早點(diǎn)，以便能達(dá)到預(yù)期的目的。如：
① You should arrive there as early as you can. 你應(yīng)盡早到達(dá)那里。
Ⅳ. as quickly as 表做某事的速度非常之快或動(dòng)作非常之敏捷。如：
① Please read the text as quickly as you can. 請把課文盡快讀一遍。
§47 as soon as/ hardly…when/ no sooner…than
Ⅰ. 三者在意義上基本相同，都有“一……就……”，“剛……就……”，但它們各有其特點(diǎn)。
Ⅱ. as soon as 最為普通，位置靈活，可在主句前，也可在其后。且可用作多種時(shí)態(tài)。如：
① As soon as I went in , Kate let out a cry of surprise. 我一進(jìn)去，凱特就驚訝地叫了一聲。
② I’ll tell him as soon as he comes back.
Ⅲ. hardly… when…的主句通常 用過去完成時(shí)，從句用一般過去時(shí)，when有時(shí)還可換成before.如：
① He had hardly finished his homework when the light went out. 他剛寫完作業(yè)燈就滅了。
② Hardly had I come back when they began quarrelling.我一回來他們就開始吵了起來。(hardly 提前時(shí)，句子需要倒裝。)
Ⅳ. no sooner…than…句型中， no sooner一般只置于句首，所以主句有倒裝形式。如：
No sooner had I known the news than I telephoned my mother. 我剛知道這個(gè)消息就打電話告訴了媽媽。
§48 as well as/ as well
Ⅰ. as well as “也”“不僅…而且”意同：not only … but also具有連詞性。
① She is my friend as well as my doctor. 他不僅是我的醫(yī)生，也是我的朋友。
② Small towns as well as big cities are being industrialized. 小城市與大城市一樣都在迅速實(shí)現(xiàn)工業(yè)化。
Ⅱ. as well “也”具有副詞性。大致相當(dāng)于also 或 too . 如：
He can speak Chinese as well.
§49 as/ because/ for/ since
Ⅰ. 這三個(gè)詞都可以用作連詞，表“原因、理由” 但有區(qū)別：
Ⅱ. as “因?yàn)?、既然”表示的原因或理由是明顯的。語意不如because強(qiáng)。當(dāng)理由是明顯的，或者被認(rèn)為是已知的時(shí)，則以用as 為好。如：
① As he was not well, I decided to go without him. 因?yàn)樗眢w不好，我決定獨(dú)自去了。
② As it was getting very late, we soon turned back. 因?yàn)橐押芡砹耍?我們很快就回來了。
③ As it is raining, you’d better take a taxi. 既然在下雨，你最好乘出租車。
Ⅲ. because “因?yàn)椤北碇苯佣鞔_的原因或理由。即必然的困果關(guān)系。在這幾個(gè)詞中，它的語意最強(qiáng)?；卮鹨詗hy 引導(dǎo)的特殊疑問句時(shí)，只能用because . 注意：because 不可以與so 連用。如：
① He had to stay at home yesterday because he was ill.昨天他只得呆在家里，因?yàn)樗×恕?BR> ② I did it because they asked me to do it. 我之所以做這件事，是因?yàn)樗埼易龅摹?BR> ③ ---Why can’t you do it now? --- Because I’m too busy.
Ⅳ. since“既然”比as 較為正式，說明為人所知的原因。語氣比because 稍弱。
① Since light travels faster than sound, we see lightening before we hear the thunder.因?yàn)楣獗嚷曇魝鞑サ每?，所以我們先看到閃電，后聽到雷聲。
② Since he can’t answer the question, you’d better ask someone.既然他回答不了這個(gè)問題，你最好問別人吧。
③ Since you are busy, I’ll do it for you.既然你忙，我替你做吧。
Ⅴ. for “因?yàn)椤北碓蚧蚶碛蓵r(shí)，用以說明理由，只是解釋性的。在這幾個(gè)詞中，它的語意最弱。它少用于口語中，也不用于句首。如：
① I asked her to stay to tea, for I had something to tell her. 我請她留下來喝茶，因?yàn)槲矣惺乱嬖V她。
② We must get rid of carelessness, for it often leads to errors. 我們一定克服粗枝大葉的毛病，因?yàn)榇种Υ笕~常常差錯(cuò)。
③ It must have rained, for the road is wet. 一定下雨了，因?yàn)槁肥菨竦摹?BR> ④ I must go now, for my sister is waiting for me. 現(xiàn)在我得走了，我姐姐在等我呢。
[注]：這幾個(gè)詞按語意的強(qiáng)弱來排，其順序?yàn)椋?BR> because—→since—→(as)—→for
§50 as/ when/ while
這三個(gè)詞都可以用作連詞，表時(shí)間關(guān)系， 但有區(qū)別：
Ⅰ. as “當(dāng)(在)……時(shí)候”往往可與when 或 while 通用，但它著重指主句和從句的動(dòng)作或事情相并發(fā)生。如：
① I saw him as he was getting off the bus. 當(dāng)下公共汽車的時(shí)候，我看見了他。
② As he walked on, he felt himself getting more and more tired.他繼續(xù)往前走的時(shí)候，感到越來越疲乏。
Ⅱ. when “當(dāng)(在)……的時(shí)候”主句和從句的動(dòng)作或事情可以同時(shí)發(fā)生，也可以先后發(fā)生。
① It was raining when we arrived. 當(dāng)我們到達(dá)的時(shí)候，正下著雨。
② When we were at school, we went to the library every day. 我們在求學(xué)的時(shí)候，每天都到圖書館去。
Ⅲ. while “當(dāng)(在)……的時(shí)候”表主句的動(dòng)作或事情發(fā)生在從句中的動(dòng)作或事情的進(jìn)展過程之中。從句通常為進(jìn)行時(shí)態(tài)。它有時(shí)可與when通用，但它只能指一段時(shí)間(a period of time),而不能指一點(diǎn)時(shí)間(a point of time)如上面的第一個(gè)例子。又如：
① Please don’t talk so loud while others are working. 別人在工作的時(shí)候，請勿大聲講話。
② While I am washing the floor, you can be cleaning the windows.我洗地板時(shí)，你可以擦窗戶。
