purpose, reason, cause 有什么区别

purpose n. 目的，意图，目标e. g. What is your purpose in doing this? 你做这件事的目的是什么？比较：for…purpose为了……目的 on purpose 有意地，故意地，特意e. g. If I go there in future, it will be for the purpose of seeing you.如果我今后去那儿的话，就是为了见你。I’ve come on purpose to speak ...reason在定语从句中的用法 2009-12-06 15:03 The reason why he could not go there was that his grades were too low.The reason why...is that... 这是特定句型, why引导定语从句,is后的用词为that,一般不用because.The reason why she did it is that she wouldn’t let her parents feel disappointed.她为什么做那件事是因为她不想让父母失望。该句中的why引导一个定语从句，而that引导表语从句。(1) 句中that引导的表语从句说明主语reason的具体内容注意以下三种结构：① The reason is / was that clause. 当主语是reason / cause时，一般不能用because或why引导表语从句，以免造成语意重复。The reason why/for which(也可以省去) he was late was that he got up late.他迟到的原因是他起床晚了。②当主语是This / That时，可以由because / why引导表语从句。He got up late. That was why he was late for class.He was late for class. That was because He got up late.(2)why在句中是关系副词，引导定语从句，修饰先行词reason，同时它在定语从句中作状语，此时why = for which，但要注意：关系词在定语从句中做主语或宾语时，要用关系代词that或which。The reason why/for which(也可以省去) he was late was that he got up late.他迟到的原因是他起床晚了。The reason that/which/(也可以省去) he gave you was reasonable.他给你的理由是合理的。cause在第二句中不能单独使用. 要用也得有the cause of

2.reason就是理由. cause是引起XXX的原因.

你别拿中文意思去忘记和理解. 这样会分不清. 你就多读这两个句子,读出声来, 在不同的时间至少读40回. 你就明白二者的区别了.这叫语感

cause用作动词，当“引起，造成，使得”讲。cause sb.sth.(=cause sth.to sb.)(后接间接宾语+直接宾语)为固定用法。
