八年级英语下册Unit6语法讲解与练习一、讲解unless, as soon as和so…that1.unless是连词，意为“如果不”、“除非”。连接一个条件状语从句，等于if…not，不同点在于：if…not是口语，unless为书面语，有否定意思。I shall go there unless it rains.=I shall go there if it doesn’t rain.我去，除非下雨（如果不下雨， 我就去）。2.as soon as一……就……，用来引导时间状语从句。在句子中的位置比较灵活，而且可以用于各种时态。I’ll write to you as soon as I get there.我一到那儿就给你来信。As soon as I got the news, I came to tell you.我一得到消息就来告诉你。若主句用一般将来时，unless引导的条件状语从句和as soon as引导的时间状语从句多用一般现在时代替一般将来时。即“主将从现”。3.so…that…“如此……以至……”引导结果状语从句。When the football fans saw Beckham, they got so excited that they cried out.当球迷们看到贝克汉姆的时候，他们如此激动以至大喊大叫。当that引导的结果状语从句为肯定句时，so…that…可以与be…enough to do转换；当从句为否定句时，可以与too…to…或be not…enough to do转换。The boy is so young that he cant look after himself.=The boy is too young to look after himself.=The boy is not old enough to look after himself.这个男孩太小而不能照顾他自己。二、练习一、单项选择。（ ）1.We couldn’t help _____ when we heard the funny story.A.laugh B.laughing C.laughs D.to laugh（ ）2.—Jack,you look tired today.What’s wrong?—I was _____ busy_____ I didn’t go to bed until midnight yesterday.A.such;that B.too;to C.so;that D.enough;to（ ）3.—Let’s go hiking ______ staying at home,shall we?—Good idea.A.as well as B.in order to C.instead of D.instead( ) 4.My mother gave me a cup of milk _________ I got home.A.so that B.as soon asC.until D.though( )5.You can't get good grades _________ you study hard than beforeA.if B.when C.unless D.so( )6.The boy is ______ young _______ he can't go to school.A.as;as B.too;toC.so;to D.so;that( ) 7.You'll get fatter _________ you exercise every day.A.unless B.if C.so D.when( )8.The little boy fell asleep ________ he got on the bus.A.until B.if C.while D.as soon as二、用连词if,unless,as soon as或so/such…that填空。1.The animals were ________ lovely ________ I spent a whole day in the zoo.2._______ it is cold tomorrow,he will stay at home and watch TV.3.I sent some flowers to her ____________ she finished speaking on thestage.4.It was _______ an interesting story ________ everyone fell in love with it.5 I won't let you in _________ you show me your pass.三、根据汉语意思完成句子，每空一词。1.他妹妹身体太弱了，不能再走了。His sister is ______ _______ ______ she can't walk farther.2.除非下雨，否则他们将不会呆在家。________ it rains,they won't ______ ______ home.3那个婴儿一醒来就哭。That baby will cry _______ _______ _______ he wakesup.4.我一到那儿就去拜访你。I will ⅵsit you ______ _______ ______ I ____________ there.5.他跑得太快，我追不上他。He ran ______ fast ________ I couldn't catch him.附：参考答案 一、1-8.BCCBC DAD二、1. so that2.if3.as soon as4.such that5.unless三、1. so weak that2.Unless stay at3.as soon as wakes up4.as soon as get/ arrive5.so that
