[英文易搞混] because of vs due to

because 

可以說是因果關係句型中最常見的字了，because 是從屬連接詞，後面要加上一個完整句子，也就是有主詞、動詞的句子。because 加上了 of 之後變成了介係詞，後面必須要加上一個名詞或是動名詞，才是正確的。

because of 

He did very well on the mid-term exam because he studied hard for it.

because 

The window of the office was broken because of the continual strong wind.

due to (prep.)

due to 是個介係詞，後面必須要加上名詞，不可以接完整句子。

(O) His failure was due to his arrogance.

(X) His failure is due to he is too arrogant.
