语法精讲条件状语从句if引导条件状语从句，请看下面例句：Ifyougototheparty,you'llhaveagreattime！如果你去参加聚会，你会玩得很开心！if引导的为条件状语从句，要遵循“主将从现”原则，即主句为将来时态时，从句使

用一般现在时表达将来的意思。这时主句和从句所表达的时态在意义上仍然保持一致。从句还可以是祈使句或含有情态动词的陈述句。如：①IfhegoestoEngland,hewillhavetolearnEnglish.如果他要去英格兰，他将不得不学英语。②Youcangetgoodgradesi

fyouworkhard.如果你努力学习，你会取得好成绩。③Comehere,ifyouwanttoknowsomethingaboutthisevent.如果你想对这个赛事有所了解，那请过来。Unless引导的条件状语从句Unlesswetalktosomeone,w

e’llcertainlyfeelworse.如果我们不与人交谈,我们必定会感觉更糟。[点拨]unless连词,意为“除非；如果不”,用于引导条件状语从句。unless可与if引导的否定的条件状语从句进行同义句转换。如：You’llbelateunlessyouhurryup.=You

’llbelateifyoudon’thurryup.如果你不快点儿,你将会迟到。1、Let’sorderfoodfromarestaurant让我们在餐厅订购食物吧！order作动词时有两种意思：①订购，下单ordersthfrom...从
