因为，除了becau，还可以如何表⽰？
以前课本或是语法书上会说
becau of 和 due to 是⼀样的意思
所以写作时可以互相替换
但真的是如此吗？
1
becau (conj.) / becau of (prep.)
becau 可以说是因果关系句型中最常见的词了，becau 是从属连接词，后⾯要加上⼀个完整句⼦。becau 加上了of 之后变成了介词，后⾯必须要加上⼀个名词或是动名词，才是正确的。
He did very well on the mid-term exam becau he studied hard for it.
他期中考考得很好，因为他很⽤功地念书。
2
due to (prep.)
due to 是个介词，后⾯必须要加上名词，不可以接完整句⼦。
(O) His failure was due to his arrogance.
他的失败是因为他的骄傲。
(X)His failure is due to he is too arrogant.
他的失败是因为他的骄傲。
3
becau of 和 due to 的区别
becau of 和 due to 两个词虽然在中⽂可能都会翻成「因为」，词性也都是介词，但是其实他们的⽤法却是不⼀样的，不可以随便替换，会造成语法错误！
becau of 前⾯必须是有⼀般动词的完整句⼦，⽽ due to 前要有名词，不能是⼀般动词（be 动词不是⼀般动词，be 动词是系动词），因为 due to 本质上是⽤来说明、形容名词的。
(O) He got sick becau of a sudden drop of the temperature.
(X)He got sick due to a sudden drop of the temperature.
因为⽓温骤降，他⽣病了。
(O)The company’s huge success is due to the team’s hard work.
(X) The company’s huge success is becau of the team’s hard work.
这间公司的伟⼤成功，是因为团队的努⼒⼯作。美甲品牌
4
owing to (prep.)只要思想不滑坡
owing to 和 becau of 词性⼀样，都是介词，且⽤法⼀样，只能⽤在有⼀般动词的完整句⼦后⾯。(O)He fell asleep as soon as he laid down owing to a lack of sleep.
他因为缺乏睡眠，⼀躺下去就睡著了。
(X)His fatigue is owing to a lack of sleep.
他的疲惫是因为缺乏睡眠。演讲的技巧
⽐较：
(O)His fatigue is due to a lack of sleep.
logo设计欣赏他的疲惫是因为缺乏睡眠。
5
since (conj.)给小树
since 不只表达原因，⾥⾯还暗藏了「既然」的⼝⽓。
大骆Since you are here, could you help me move this heavy box?
你在这⾥，你可以帮我搬这个重箱⼦吗?
黄世博⽐较：since (prep.)
读书感悟怎么写since 也很常被拿来当作介词⽤，意思是「⾃从」后⾯要加上⼀个过去事件或是时间点。
He has lived in San Francisco since 1987.
他⾃从1987年就住在旧⾦⼭了。
He has been depresd since his wife pasd away.
⾃从他的妻⼦过世后，他就⼀直很沮丧。
