三精考点之九年级英语最易错考点系列：2.too…to…句式与so…that…引导的结果状语从句

最易错考点系列 一 too…to…句式与so…that…引导的结果状语从句 ★★★ ○○○○ too…to…结构，其意为“太……以至于不能……” 如：He is too shy to speak to her. 他太害羞，不敢同她讲话。 It’s too cheap to be good. 这东西太便宜，好不了(即便宜无好货)。 He is too young to know right from wrong. 他太小，还分不清是非。 在so…that…句型中，so后面加形容词或副词，其意为“如此……以至于……”。 如：1) This book is so interesting that everyone wants to read it. 这本书很有趣，人人都想看看。 2) He ran so fast that I couldn’t catch up with him. 他跑得那么快，我没赶上他。 2、so… that…引导的是表示结果的状语从句，但不一定是“如此……以至于……”。 如：1) The workers did so well that he was pleased with them. 工人们干得很好，他对他们很满意。 2) I was so busy here (that) I had no time to write a letter. 我在这里很忙，没时间写信。 3、so that引导目的状语从句，其从句中的谓语动词通常和can, may, should等情态动词连用，而且主句和从句之间不使用逗号，意为“以便，为了，使能够”。 如：1) They got up early so that they could catch the early bus. 为了能赶上早班车，他们早早就起床了。1. 当主句和从句的主语一致，且that从句是肯定句时，可用“enough to do sth.”来转换。 例如：The man is so strong that he can lift the heavy box.→ The man is strong enough to lift the heavy box. 2. 当主句和从句的主语不一致，且that从句是肯定句时，可以用“enough for sb. to do sth.”来替换，但须注意不定式的宾语要省略。 例如：The question is so easy that I can work it out. → The question is easy enough for me to work out. 3. 当主句和从句的主语一致，且that从句是否定句时，可以用“too...to”来替换。 例如：The girl is so young that she can't dress herself. → The girl is too young to dress herself. 4. 当主句和从句的主语不一致，且that从句是否定时，如果要用“too...to...”替换“so...that...”，则用介词for引出动词不定式的逻辑主语，可以用“too...for sb. to do sth.”来替换， 注意不定式的宾语要省略。 The bag is so heavy that she can't move it. → The bag is too heavy for her to move. 1.
