3、uch修饰名词，意思也是“如此以至于”但当名词前有many, much, (a) few, (a) little等词修饰时，句子中要用“so.that.”而不能用“such.that.”。例如： He has so much money that he can buy what he wanted.

4、 that everybody got bored. There was so little water in the jar that it was not enough for all of us. （注：当little的意思是“小”时，仍用such.that.）,sothat,【知识点解析】,4. so与that也可连起来写，即变成：. so that .

(目的状语从句) Maria likes the woolen dress so that she decides to buy it immediately. (结果状语从句) so that
13、引导目的状语从句时，表示“以便；为了”，从句中常使用can /could /may /might /will /would /should等情态动词或助动词；引导结果状语从句时，从句中一般不用can和may等词。,sothat,【知识点解析】,so that引导的目的状语从句之前不用逗号，而so that引导的结果状语从句与主句之间往往有逗号相隔开（即略作停顿），意思是“因此；所以”。请比较： He worked hard at his lessons so that he could gain high grades in the exams. 他努力学习功课，争取考试能获得好成绩。 He
