Module5if引導(dǎo)的條件狀語從句從本模塊起，我們開始學(xué)習(xí)if引導(dǎo)的條件狀語從句。我們首先學(xué)習(xí)"if從句+祈使句"結(jié)構(gòu)，相當(dāng)于漢語的"如果……，就……"。我們來看幾個(gè)例句：Ifyouwanttogo,pleasetellme.如果你想去的話，請(qǐng)告訴我一聲。Ifyouwanttoknowmoreaboutit,callnow.如果你想了解更多內(nèi)容，現(xiàn)在就打電話吧。Ifyouwanttoknowwhattosee,lookattheguide.如果你想知道有什么可看的，就讀一下指南吧。從例句中可以看出，if引導(dǎo)的條件狀語從句不是指已經(jīng)發(fā)生的事件，而是指能夠發(fā)生或可能發(fā)生的事件。(1)if從句的位置if引導(dǎo)的從句可以放在主句之前，也可以放在主句之后。例如：IfyouevergotoLondon,makesureyouvisittheScienceMuseum.如果你去倫敦，一定要去參觀科學(xué)博物館。這個(gè)句子可以改寫為：MakesureyouvisittheScienceMuseumifyouevergotoLondon.當(dāng)if從句放在主句之前時(shí)，通常用逗號(hào)與主句隔開；當(dāng)if從句放在主句之后時(shí)，一般不需要逗號(hào)。(2)if從句的用法本模塊主要學(xué)習(xí)并運(yùn)用"if從句+祈使句"這種結(jié)構(gòu)來表達(dá)建議。比如說，如果對(duì)方生病了，你建議他去看醫(yī)生，就可以說：Ifyoudonotfeelwell,pleasegotoseethedoctor.你如果感覺不舒服，就去看醫(yī)生吧。在if引導(dǎo)的條件狀語從句中，即使表示將來的情況，從句也要用一般現(xiàn)在時(shí)，而主句用祈使句或?qū)頃r(shí)。例如：Ifitrainstomorrow,wewillcancelthepicnic.如果明天下雨，我們就取消野餐。Ifyouseehim,tellhimtocallme.如果你見到他，讓他給我打電話。
