中考語法復(fù)習(xí)：狀語從句講解及提升練習(xí)（含答案）

1、狀語從句狀語從句指的是在主從句中作的從句，修飾主句中的動詞、形容詞或副詞等。狀語從句放在主句之前時，常用逗號分開；假設(shè)放在主句之后，一般不用逗號。按其意義和作用劃分，初中階段常見的有以下幾種:時間狀語從句一般來說，時間狀語從句常由連詞when, before, after, as soon as或until引導(dǎo)。在使用時,從句一般不用一 般將來時態(tài)。假設(shè)主句為一般將來時態(tài)或是含有將來的意味時，時間狀語從句常用一般現(xiàn)在時態(tài)來代替將來，即 “主將從現(xiàn)”。如：I will go to the cinema as soon as I finish my homework.我一完成作業(yè)就去 電影院。Wh

2、en I grow up, I will join the army.當(dāng)我畢業(yè)了，我就要去參軍。條件狀語從句條件狀語從句常由if （如果）、unless （除非）或aslongas （只要）來引導(dǎo)，同樣適用于“主將從現(xiàn)”。 如：We will stay at home if it rains tomorrow.如果明天下雨了，我們就會呆在家。He won t come here unless he is invited.除非被邀請，否那么他不會到這兒來的。As long as you give me money, I will go with you.只要你給我錢,我就跟你走。原因狀語從句原因

3、狀語從句常由because （因為），since （既然；由于）或as （由于）來引導(dǎo)。在使用時，注意because 和so （所以）不能用在同一個句子中。如：Since you can? t help me, T 11 find someone else.既然你幫不了我,那我就找其他人吧。He failed the exam because he didn t work hard.=He didn? t work hard, so he failed the exam.因為他不努力，所以考試沒有及格。讓步狀語從句讓步狀語從句由although或though （雖然;盡管）來引導(dǎo)。注意，在使用

4、時，though或although不能和 but不能用在同一個句子中，兩者只能用其一。如：We still worked in the field although / though it was raining hard.=It was raining hard, but we still worked in the field.盡管天下著大雨，但是我們?nèi)匀辉诘乩锔苫?。目的狀語從句目的狀語從句主要由 氣0由譏”（以便，為了）或“皿。出已由沆”（為了）來引導(dǎo)，謂語中常含有11，18H, can, could, will, would 等情態(tài)動詞。如：He gets up early every

5、 morning so that he can catch the bus.他每天早上起得都很早，以便能趕上公交車?！緶剀疤崾尽慨?dāng)從句主語與主句主語一致時，可用so as to, in order to。如:He worked day and night in order that he could succeed.=He worked day and night in order to succeed. 他夜以繼日地工作為的是取得成功。結(jié)果狀語從句結(jié)果狀語從句主要由“so that（結(jié)果是），“sothat/suchthat （如此以至于）來引導(dǎo)。如:It s so hot that nob

6、ody wants to go out.外面太熱，以至于沒人想出去。.that 與 such.that 的區(qū)別 X So +形容詞或副詞+ thatX Such + a/an （+形容詞）+單數(shù)名詞+ thatX Such + （形容詞）+復(fù)數(shù)名詞+ thatX Such + （形容詞）+不可數(shù)名詞+ thatX So +形容詞+ a/an +單數(shù)名詞+ thatunless引導(dǎo)的條件句，表示強(qiáng)烈的否認(rèn)。翻譯為“除非”?！胺遣豢??！盜 shant go unless he asks me.他不來請我我就不去。You will fail unless you work harder.你不努力就會

7、失敗的。Dont come unless 1 call you.我不叫你就另U來。注意：unless從句里的謂語只能是肯定式,因為本身unless表示否認(rèn)。誤 : Unless you do not work, you will fail.正 ： Unless you work hard, you will fail.正 ：If you dont work hard, you will fail.as long as引導(dǎo)條件狀語從句,表示“只要”。As long as you study hard, you wont fail in the exam.【溫馨提示】X主將從現(xiàn)原那么：主句為一般將

8、來時，從句用一般現(xiàn)在時；如：ril visit the Great Wall if it doesnt rain tomorrow.如果明天不下雨，我將去游覽長城。X如果if引導(dǎo)的條件狀語從句所表示的前提或條件正在進(jìn)行，從句要用進(jìn)行時，主句通常用將來時；如: We will give you a good price if you are thinking of buying it.如果你考慮買它，我們會給你一個好價錢。X“祈使句+and/or引導(dǎo)的結(jié)果狀語從句”中，祈使句在意義上相當(dāng)于一個條件狀語從句；如：Use your head, and youll find a way.=If you

9、 use your head, youll find a way.動動腦筋，你就會想出方法來。運(yùn)翼型例題 1.
