Unit 1　Great explorations 课时 3 语法 课时精讲 单元语法讲解：结果状语从句 一、结果状语从句 结果状语从句是表示动作或事情结果的从句， 通常主句是原因， 从句是结果， 从句通常位于主句之后。 1.结果状语从句由so…that, such…that, so that引导。 例如：He is so poor that he can't buy a bike for his son. She is such a good teacher that everybody likes her. My pencil fell under the desk，so that I couldn't see it. 返回目录 第 ‹#› 页 2.so…that与such…that的用法区别。 在由so…that引导的结果状语从句中，so是副词，与形容词连用。 其结构是： “so＋形容词(副词)＋that从句”。 例如：He was so glad that he couldn't say a word. The hall is so big that it can hold 2，000 people. Mother lives so far away that we hardly ever see her. 在由such…that引导的结果状语从句中，such是形容词，它修饰的可以是单数或复数可数名词，也可以是不可数名词；名词前面可以带形容词，也可不带。如果是单数可数名词，前面需加不定冠词a或an。其结构是：such (a/ an)＋adj.＋n.＋that从句 返回目录 第 ‹#› 页 例如：It was such a hot day that nobody wanted to do anything. He had such long arms that he could almost touch the ceiling (天花板)． He made such rapid progress that he did very well in the mid-term exam. 有时上述两种结构可互换： 返回目录 第 ‹#› 页 ▲ such a/ an ＋adj.＋n. ＋ that 从句 ＝ so＋adj.＋a/ an ＋ n. ＋ that 从句 (1)The film was so wonderful that all of us wanted to see it again. ＝ It was such a wonderful film that all of us wanted to see it again. ＝ It was so wonderful a film that all of us wanted to see it again. (2)The match is so important that nobody wants to miss it. ＝ It is such an important match that nobody wants to miss it. ＝ It is so important a match that nobody wants to miss it. 返回目录 第 ‹#› 页 3.如果名词前有many, much, little, few等词修饰时，只能用so, 不用such。 ▲ so many/much/few/little ＋ n．＋that 从句 例如：Soon there were so many deer that they ate up all the wild roses. He has so little time that he can't go to the cinema with you. 返回目录 第 ‹#› 页 二、too…to & enough to 除了可以用结果状语从句表示结果， 我们还可以用too…to和enough to来表示结果。 1.too…to 含义： 太……以至于不能…… 结构：too＋adj./adv.＋(for ＋ n. / pron.) ＋ to do sth. ＝ so＋adj./ adv.＋that sb. couldn't/ can't do sth. 例如：The house is too expensive for the poor to buy. ＝ The house is so expensive that the poor can't buy it. 例如：The child was too young to go to school last year. ＝
