2、there.當(dāng)你到那時(shí),請(qǐng)給我打個(gè)電話。I will write to you as soon as I arrive in Beijing.我一到北京就給你寫(xiě)信。<溫馨提示>since引導(dǎo)時(shí)間狀語(yǔ)從句表示“自從以來(lái)”,從句中的動(dòng)詞一般表示動(dòng)作的起點(diǎn),用過(guò)去時(shí);而主句的動(dòng)作延續(xù)的情況則用一般現(xiàn)在時(shí)或現(xiàn)在完成時(shí)。常用的句型為:It has been/is+一段時(shí)間+since+過(guò)去時(shí)。如:I has been/is three years since we met last time.自從我們上次見(jiàn)面,已經(jīng)三年了。2條件狀語(yǔ)從句引導(dǎo)條件狀語(yǔ)從句的連詞或詞組有:if(如果,unless

3、(除非,as long as(只要等。如果主句是將來(lái)時(shí),條件狀語(yǔ)從句也用一般現(xiàn)在時(shí)來(lái)表示。如:I will stay at home if it rains tomorrow.如果明天下雨,我就待在家。You cant learn English well unless you wo rk hard.除非你努力學(xué)習(xí),否則是學(xué)不好英語(yǔ)的。<溫馨提示>由if引導(dǎo)的條件狀語(yǔ)從句,若從句表達(dá)的是與現(xiàn)在事實(shí)相反的事實(shí),則常用虛擬語(yǔ)氣,即用過(guò)去時(shí)態(tài)表示(如果涉及到be動(dòng)詞,一律都用were。此時(shí),主句則用過(guò)去將來(lái)時(shí)。如:If I had enough money,I would buy it

4、for you.如果我又足夠的錢(qián),我將把它買(mǎi)給你。I wouldnt do it if I were you.如果我是你,我是不會(huì)做的。3原因狀語(yǔ)從句because,since,as,for都可用來(lái)引導(dǎo)原因狀語(yǔ)從句,那么它們又有哪些區(qū)別呢?because用來(lái)表示“造成某種結(jié)果的直接原因”,語(yǔ)氣較濃,常用來(lái)回答why提出的問(wèn)句。如:-Why are you late?-Because my bike is broken.as和since用來(lái)表示“看的到的或是不說(shuō)也知道的原因”,since也可譯作:“既然”。如:As he is old enough,let him do it.他既然長(zhǎng)大了,就讓

5、他干吧!Since his sho es are worn out,lets buy him a new pair.既然他的鞋壞了,那我們就給他買(mǎi)雙新的吧。for引導(dǎo)的原因狀語(yǔ)從句不置于句首,常用來(lái)表示“順便提及的理由”,只是稍帶說(shuō)明原因,并非強(qiáng)調(diào)。如:I must stay here,for its raining so hard.我必須得待在這兒,因?yàn)橛晗碌暮艽蟆３踔杏⒄Z(yǔ)狀語(yǔ)從句知識(shí)點(diǎn)總結(jié)(二1狀語(yǔ)從句在復(fù)合句中,修飾主句中的動(dòng)詞、形容詞或副詞等的從句叫狀語(yǔ)從句。狀語(yǔ)從句根據(jù)它表達(dá)的意思可分為時(shí)間、地點(diǎn)、原因、目的、結(jié)果、讓步、比較(或方式和條件等類。1.時(shí)間狀語(yǔ)從句引導(dǎo)連詞有when,w
