　　back ��

　　［誤］ I‘m sorry. I have to back home.��

　　［正］ I‘m sorry. I have to go back home.��

　　［正］ I‘m sorry. I have to go home.��

　　［析］ back用作“回到(某處)”之意，不是動詞。��

　　be ��

　　［誤］ Where do you from?��

　　［正］ Where are you from?��

　　［析］ “你從何處來”應為Where are you from？或Where do you come from？ 但要注意這兩句話均是問對方從哪個國家來的。要是口語中問“你是從什么地方來？”應講Where did you come from？回答用I came from the library.��

　　beat ��

　　［誤］ We have won your class.��

　　［正］ We have beaten your class.��

　　［正］ We have won the game.��

　　［析］ win是勝過之意，它是及物動詞，但其后的賓語只能接比賽、戰爭、獎品、獎金的名稱，如：Which team won the football match? 而beat指打敗對手、敵人……如：My brother beat me at poker.(要注意的是，beat的過去式與原形相同，而過去分詞為beaten)。��

　　［誤］ The ball beat me badly.��

　　［正］ The ball hit me badly.��

　　［誤］ He used to hit the little boy black and blue.��

　　［正］ He used to beat the little boy black and blue.��

　　［析］ beat指打擊多次，而hit則為擊中對方的一次性打擊。��

　　beautiful ��

　　［誤］ He is a beautiful boy.��

　　［正］ He is a handsome boy.��

　　［析］ 我們可以講She is a beautiful girl. This is a beautiful park. 但要講男人的"英俊"時要用handsome.��

　　because ��

　　［誤］ The reason why I was late is because I was ill.��

　　［正］ The reason why I was late is that I was ill.��

　　［誤］ Because it was Sunday, so the park was crowded.��

　　［正］ Because it was Sunday the park was crowded.��

　　［析］ 這種錯誤是因為中文的習慣與英語的表述法不同，中文常講我來晚了的原因是因為我病了，而英文中的第二個因為要用that代替。又因中文常講因為……所以……，而英文中用了因為就不能再用所以了，同樣用了"所以"也就不要再用"因為"一詞。例如：Because we study hard, we passed the exam easily. 或者：We study hard so we passed the exam easily.��

　　because、because of ��

　　because后要接從句，例如：We like physics because we can learn a lot of new ideas. 而because of后要接名詞作介詞賓語，如：He is not at school because of the illness.��

　　before ��

　　［誤］ We have two hours to kill before we will go home.��

　　［正］ We have two hours to kill before we go home.��

　　［析］ kill time意為"消磨時光"。��

　　英語狀語從句中要用一般現在時表示將來的動作。如：If it rains we will not go to the park.

　　［誤］ I did this work two days before.��

　　［正］ I did this work two days ago.��

　　［析］ 用ago組成的時間狀語其主句中的謂語動詞要用過去時，而before引起的時間狀語其主句中的謂語動詞多用完成時，如：I has done this work a few days before.��

　　before long、long before ��

　　before long是"不久"之意，例如：I shall go to America before long. 而long before則是"很久很久"之意，如：We knew this teacher long before we saw him. (我們在看到這位老師之前很久就知道他了。)��
