the reason什么时候用why 和because

the reason什么时候用why 和because

首先纠正一下the reason后面的从句连词只能是why 或是that
不可以有because
reason + clause
1) reason+定语从句
a.关系副词充当定语从句的原因状语,可以用why或that或省略.
The reason I called was to ask about the plans for Saturday.- Longman
The reason why（或者that）he doesn’t come is that he is ill.——《英汉大词典》
The reason that [why] he died was lack of medical care.——《用法词典》
That’s one of the reasons he always gets on my nerves.——《用法词典》
备注：关系副词可以用for which代替.
The first question is whether the reason for which Google considered entering the wholesale broadband market in the first place still holds.
b.关系代词充当定语从句的主语或宾语,可以用that或which,与一般的定语从句用法相同.
What is the reason that he gave for this?
What was the reason which led the slaves to leave the estates in British Guiana?
2) reason+同位语从句,用that引导.
We decided against installing new heating apparatus,for the reason that it would be too costly.
——《用法词典》

2 reason + for/of/to（小品词）

What was the reason for（或者of）him being late?——《英汉大词典》
备注：
reason作“理由,原因”讲时,通常作可数名词,其前常与for搭配；作“充足理由”讲时,为不可数名词,后面多跟不定式.（以下例句来自Longman）
The tower is closed for reasons of safety.
There was no reason to panic.
We have reason to believe that the goods were stolen.
Under the circumstances,we had every reason to be suspicious.
这是reason后面接从句的用法 希望对你有所帮助
再问： What is the reason that he gave for this?为什么是定语从句啊 但他有时确实有because的时候 谢谢啦！
再答： What is the reason that he gave for this?是定语从句啊 不一定定语从句就是陈述句啊 本句 that he gave for this修饰reason 啊 就是指 他给这件事的理由 明显就是定语从句 如果用到because那么就是2个句子 因为reason后面接的所以从句形式我已经都列举了 because不可能作为reason后面的从句的连词 呵呵 如果有 那么那就是个病句 语法规定的 只可能是that 或是why 嘿嘿 希望对你有所帮助哈 lz可以从定语从句的方向复习一下 判断什么句子是定语从句 对解决lz这个问题会有帮忙喔 O(∩_∩)O~ 加油~\(≧▽≦)/~啦啦啦
