Unit6Anoldmantriedtomovethemountains.revision1.unless是連詞，意為“除非；如果不,除了…”引導(dǎo)條件狀語從句，含否定意義，相當(dāng)于if...not.

unless引導(dǎo)條件句時(shí)，主要用于下列情況。unless(1)主句為肯定句。如：你要不快點(diǎn)就會錯過班車。Youwillmissthebusunlessyouhurryup．

(2)主句為否定句。如：Hewillgotothepartyunlessitdoesn’train.assoonas意思為“A事件發(fā)生后就做B事件”，“一……就……”，引導(dǎo)時(shí)間狀語從句。assoonas在每一個大的時(shí)間段內(nèi)，A和B的時(shí)態(tài)要統(tǒng)一。A現(xiàn)在時(shí)assoonasB現(xiàn)在時(shí)A過去時(shí)assoonasB過去時(shí)IwenttododishesassoonasIcamebackhome.A將來時(shí)assoonasB將來時(shí)(用一般現(xiàn)在時(shí)表將來)Theywilleatdinnerassoonasheleaves

here.assoonas指緊接著發(fā)生的兩個短動作，主從句都用一般過去時(shí)。如：HetookouthisEnglishbooksassoonashesatdown.so...that表示“如此……以至于……”，常用于引導(dǎo)結(jié)果狀語從句。主語+謂語+so+adj./adv.+that從句。Hewassoexcitedthathecouldn’tsayaword.Sheissoyoungthatshecan'tlookafterherself.so+adj.+a(n)+單數(shù)名詞+that從句。她做的飯菜那么好吃，結(jié)果我們都吃得太多了。Shemadeso

goodamealthatweatefartoomuch.so...that在“such…that…”句型中，such修飾名詞，意思是“如此……以致于……”。但當(dāng)名詞前有many、much、(a)few、(a)little等詞修飾時(shí)，句子中要用“so…that…”而不能用“such…that…”。例如：Hehassomuchmoneythathecanbuywhathewanted.1.Hewas___excited_____hecouldn’tgetsleep.2.Thisis___interestingabook____weallenjoyreadingit.3.Youcansoongetoutofpractice______youplaythepianoregularly.4._________shesaysitIunderstand.5.Thesportsmeetwillcontinue_____itrainsthisafternoon.練一練：sothatsoAssoonasunlessunlessthat根據(jù)提示完成句子。
