其中，我將幾個觀察到學生經常犯的錯誤羅列如下，有興趣的人可到網址上查看全文
Advise and Advice
除了兩者發音不同(advise最後有z的音)，advise是advice的動詞形式。
正確: I advise you to …
錯誤: Thank you for the advise. 應為 Thank you for the advice.
Well and Good
Good是形容詞，而Well是副詞。但口語上我們常常會這樣說，"I don't feel good." 也就是 "I don't feel well." 這在日常生活上可以，但在商用英文就必須注意文法錯誤囉!
正確: You did a good job.
正確: You did incredibly well.
錯誤: You did good.
If and Whether
If 和 Whether經常是可以互換的，但是在回答yes/no情況下。例如，“I wonder whether Jim will finish the project on time” or ”I wonder if Jim will finish the project on time.”
但當if是在假設情況下使用， 例如，“Let me know if Marcia needs a projector for the meeting.” 這句話的意思是"如果Marcia需要投影機再告訴我。"
但是替換成whether意思就變成"不管Marcia需不需要都告訴我"(“Let me know whether Marcia needs a projector for the meeting.” )
正確: “If you hit your monthly target, I’ll increase your bonus.” (若達成目標，才增加獎金)
正確: “Whether you are able to hit your monthly target is totally up to you” (能否達成目標完全在你身上)
Award and Reward
Award是獎、獎項(競賽或比賽後的結果)。如: Grammy
Awards 葛萊美獎、Employee of the
Month awards本月最佳員工。
Reward是因為努力、成就、辛苦工作等給予的回報、獎賞。 例如: sales commission is a reward. 業績抽成是獎賞 A
bonus is a reward. 獎金是獎賞。
正確: Be happy when your employees win industry
or civic awards, and reward them for the hard work and sacrifices they make to
help your business grow.
Continuously and Continually
Continuously代表連續不斷. 舉例: Hopefully your
efforts to develop your employees are continuous, because you never want to
stop improving their skills and their future.
Continual代表頻繁、不斷重複. 舉例: You might have frequent disagreements with your
co-founder, but unless those discussions never end (which is unlikely, even
though it might feel otherwise), then those disagreements are continual.
正確: That’s why you should focus on continuous
improvement but only plan to have continual meetings with your accountant: 前者的continuous是永遠不會停止，而後者continual會中斷的
Between and Among
Between用在有自己名稱的個別事物，例如: “The team will decide between Mary, Marcia, and Steve when we
fill the open customer service position.” Mary, Marcia, and Steve 三者不同且分開，所以可以用Between。
Among用在三人、三者或以上但沒有自己名稱，例如: “The team will decide among a number
of candidates when we fill the open customer service position.”
假使只有兩人、兩者，就算不知道個別名稱也可以用Between，例如: “I just can’t decide between them.”
