15、top of the tree.=I am so tall that I can reach the top of the tree. Note2: 此句是否定句式时，既可以用sothat引导的结果状语从句来替换，还可以用tooto句式替换。例：(1)他太小不能去上班。He is not old enough to go to work. He is so young that he cant go to work. He is too young to go to work. 再如： 这个箱子太重我搬不动The box is not light enough for me to carry.

17、n to play football in the street. 对孩子来说在街上踢足球是很危险的。 Its very kind of you to say so. 你这样说真是太好了。 该句式中，引导动词不定式的逻辑主语的介词用for还是of，主要取决于前面的形容词。如果形容词是描述动词不定式的行为者的性格、品质的。如：kind, good, nice, wrong, right, clever, careless, foolish等，应用of；如果形容词仅仅是描述事物，不是对动词不定式的行为者的品质进行评价的，就用for. 常见这类形容词有difficult, easy, hard, i

18、mportant, dangerous等。 Its wrong of you to do it. 你做这件事是错的。 Its hard for you to be a lawyer. 对你来说做律师很困难。F）主+would like / love to do sth. 喜欢（想做某事） Id like to go there with you. 我很想和你一起去那。 Id love I like to help you study English. 我很愿意帮你学英语。 此句式还可以扩展为： would like / love sb. to do sth. “喜欢/想让某人做某事。” Id

19、like you to stay here. 我想让你留在这。 Id like them to help me. 我想让他们帮助我。G） Why dont you +动词原形+？（Why not动词原形？）你为什么不？ 这本书有点难，为什么不读些容易的？ This book is a bit hard, why not read something easier?
