1、动词不定式做状语时表示目的和结果用法总结1.作目的状语:Icameheretoseeyou.Tostopthetrain,pulltheleverdownwards.目的状语还可以用如下表达法：肯定：toinorderto+动词原形soastoIcometoseeher.=Icomeinordertoseeher.=Icomesoastoseeher.thatsothat+主语+may/might+动词原形inorderthatIcomethatImayseeher.=IcomeinorderthatImayseeher.=IcomesothatImayseehe

3、,sothat的区别inorderto可以用在句首或句末，但soasto只能用在句末。如：Hegotupveryearlyinorderto/soastocatchthefirstbus.Inordertocatchthefirstbus,hegotupveryearly.（此时不能用soasto）soasto和inorderto的汉语意思应该是一样的“为的是，为了”。它们的英语功能也是一样的，都可以用来引导目的状语。它们的不同之处就在于soasto不能用于句子的开头，在句子开头只能用inorderto.另外，1.inorderto一般用inorderthat加从

4、句来替换；而soasto一般用sothat加从句来替换。inorderthat可以在句首，sothat和soasto一样不能在句首。2.当这两个短语后的不定式动词的逻辑主语和句子的主语一致时，“inorderto,soasto+不定式”可以简化为“不定式”Inordertogettoschoolontime,hegotupearlier.这个句子可以表达为下列几种方式：Inorderthathecouldgettoschoolontime,hegotupearlier.Hegotupearlierinordertogettoschoolontime.Hegotup
