版主職於電腦公司，常與國外大廠通電子郵件，偶而收到同仁轉寄的信件，一讀之下才發覺國人所犯的英文錯誤真是千奇百怪，日後版主會整理相關內容，說明國人常犯的英文錯誤。

「因為」的用法常被國人誤用，現分析如下：

1. because
這是最常見的用法，運用的範圍也最廣。如果網友無法確定該用哪個英文字來表達「因為」的概念，用這個單字最穩妥。

 (例句)
 She is in a bad mood becasue her mother won’t let her go to the party. 
“This photograph doesn’t look like you.” “That’s because it isn’t mine.”
“Why did you pull me over, officer?” “Because you were speeding.”  

2. because of
類似於 because，後面接名詞。

3. since
用來說明為何要做某件事情，或者建議做某件事情 (used to introduce the reason why you decide to do something or suggest doing something)。

(例句)
We had planned to play tennis, but since it was raining we decided to go swimming instead.

4. due to
(在正式的場合) 說明失敗或者遇到困難的原因 (used especially in official statements to introduce the reason for a difficulty or failure)。
這個詞語常被誤用，後面接    
1: 名詞 
2: the fact that + 子句 (有些人認為這種句型笨拙且累贅 clumsy and wordy)

(例句)
Our problems were due to a combination of bad management and bad luck.
Due to circumstances beyond our control, we regret to inform our customers that this store will close early.
By now I’m sure you know that due to the economy and other factors RIOY has suffered some huge setbacks in its income over the last few months.

5. as
說明為何某種狀況之所以存在，或者說明為何要做某件事情以及建議做某件事情  (used to introduce the reason why  a particular situation exists, why someone decided to  do something or suggest doing something)。
使用 as 這個字時要謹慎，因為 as 有時可以表示「當… 」的意思。請參照下例：

As I was doing my homework, my mum prepared my supper. (As = because)
(當時因為我正在做功課，我母親便幫我準備晚餐。)
As I was doing my homework, my mum prepared my supper. (As = while)
(當時我正在做功課，而我母親正幫我準備晚餐。)

(例句)
As he had been in prision for several times, he was a prime suspect for the case.

6. out of curiosity (interest, desperation, etc)
說明某人為何做異於平常之事  (used when someone has done something he would not normally do)。

(例句)
Just out of curiosity, why did you take that job?

7. on account of 
說明困難、問題或失敗的原因  (use when you want to explain the reason for a difficulty, problem, or failure)。

(例句)，
He can’t run very fast on account of his asthma.

8. for 
屬於正式用法，用來補充說明原因，因果的關係較 because 為薄弱。

(例句)
He found it increasingly difficult to read, for his eyes were failing.
Tom’e wife has never discovered that she married a dustman, and she never will, for he has just found another job.

9. owing to  
屬於正式用法，用來說明某件事情為何發生。

(例句)
Owing to Princess Diana’s ill-health, her visit to the new school is to be postponed.

10. by (in) virture of   
本詞語後接的原因都屬於正面。

(例句)
He was awarded a Cross by virtue of his long military service.
