语法规则—动词不定式.docVIP

(一) 动词不定式做状语时表示目的和结果用法总结 作目的状语: I came here to see you. To stop the train, pull the lever downwards. 目的状语还可以用如下表达法： to in order to + 动词原形 so as to I come to see her. = I come in order to see her. = I come so as to see her. that so that + 主语 + may/might + 动词原形 in order that I come that I may see her. = I come in order that I may see her. = I come so that I may see her. 否定： not to in order not to + 动词原形 so as to that so that + 主语 + may/might + 动词原形 in order that = He went away in order not to see me. = He went away so as not to see me. = He went away in order that he might not see me. = He went away that he might not see me. = He went away so that he might not see me. in order to, in order that和so as to, so that的区别 in order to可以用在句首或句末，但so as to只能用在句末。如： He got up very early in order to/so as to catch the first bus. In order to catch the first bus, he got up very early.（此时不能用so as to） so as to 和in order to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so as to 不能用于句子的开头，在句子开头只能用in order to.另外， 1.in order to 一般用in order that加从句来替换；而so as to 一般用so that加从句来替换。in order that 可以在句首，so that和so as to 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，“in order to , so as to +不定式”可以简化为“不定式” In order to get to school on time, he got up earlier.这个句子可以表达为下列几种方式： In order that he could get to school on time, he got up earlier. He got up earlier in order to get to school on time. He got up earlier in order that he could get to school on time. He got up earlier so as to get to school on time. He got up earlier so that he could get to school on time. To get to school on time, he got up earlier. （这种不定式有时可以表示目的以外的状语） …to”来表示。如： My father bought a new book for me to read. 作状语: What have I done to offend you? 结果状语还可以用如下表达法： so + + (表示正面的结果，解释为“如此...以至于”) adv that + 主语 + can/could + 动词原形 adj = + enough to + 动词原形 (表示正面的结果，解释为“如此...以至于”) adv He s
