看看上面是不是我們?cè)谏钪薪?jīng)常表達(dá)的句子，當(dāng)我們想描述一種假設(shè)的情況，或是預(yù)測(cè)將來(lái)可能發(fā)生的事情，還有就是沒(méi)有假設(shè)或潛在的可能，只是表達(dá)科學(xué)事實(shí)，就會(huì)用到這些英語(yǔ)句型-條件句。

條件句一般由“if"引導(dǎo)，"if"從句告訴你條件（If you study hard)，主句告訴你結(jié)果(you will pass your exams）。今天就跟大家聊聊零條件句、第一條件句、第二、第三條件句以及混合條件句的語(yǔ)法規(guī)則以及在現(xiàn)實(shí)生活中的實(shí)用表達(dá)。

#Zero conditional 零條件句# 

我們用零條件句來(lái)談?wù)撈毡檎_的事情，尤其是自然規(guī)律、法律規(guī)則等。句型結(jié)構(gòu)是：if/when+一般現(xiàn)在時(shí)。

第一條件句是當(dāng)我們談?wù)撐覀冋J(rèn)為真實(shí)或可能發(fā)生的未來(lái)情況時(shí)會(huì)用到的，第一條件句的句型結(jié)構(gòu)通常是：從句if/when+一般現(xiàn)在時(shí)，主句will+不定式。用unless,as long as,as soon as或in case代替if也很常見(jiàn)。

#Second conditional第二條件句#

第二條件句用于想象中的現(xiàn)在或?qū)?lái)時(shí)的情況，但這種情況在現(xiàn)實(shí)中無(wú)法或很難實(shí)現(xiàn)。句型結(jié)構(gòu)通常是：if+一般過(guò)去時(shí)，主句+would+不定式。當(dāng)"if"后面跟動(dòng)詞be時(shí)，用"if I were,if he were,if she were,if it were".但是我們也經(jīng)常聽(tīng)到與"was"連用，尤其是he/she形式。

#Third conditional第三條件句#

第三條件句是用來(lái)想象一個(gè)不同的過(guò)去，我們想象過(guò)去情況的變化以及這種變化帶來(lái)的不同結(jié)果。第三條件句結(jié)構(gòu)通常是：從句if+過(guò)去完成時(shí),主句would have+過(guò)去分詞。

過(guò)去/現(xiàn)在：想象過(guò)去情況的變化對(duì)現(xiàn)在的影響，句型結(jié)構(gòu)：從句if+過(guò)去完成，主句would+不定式
