【名师讲解】
1. above/ over/ on
这三个介词都表示“在……之上”，但含义不同。on指在某物的表面上，和某物接触；above指在某物的上方，不和某物接触，但也不一定在某物的正上方；over指在某物的正上方，不和某物接触。试比较：
There is a book on the desk.课桌上有一本书。
I raise my right hand above my head. 我把右手高举过头。
There is a stone bridge over the river. 河面上有座石桥。
2. forget to do sth./forget doing sth.
forget to do sth.意思是“忘记做某事”，实际上还没做；forget doing sth,意思是“忘记做过某事”，实际上已经做过了。试比较：
I forgot to tell him the news.我忘记告诉他这条消息了。
I forgot telling him the news.我已经把这条消息告诉他了，我却忘了。
类似的词还有：remember, regret等。
3. hope/wish
hope和wish 在汉语中都有“希望”的意思，但其含义和用法有所不同。主要区别如下：
(1)wish可以用来表示不可实现的愿望；hope只能用来表示可能实现的愿望。例如： I wish I were 20 years younger.我但愿自己能年轻二十岁。
I hope you?ll be better soon. 我希望你能很快好起来。
I wish the weather wasn?t so cold. 但愿天气不这麽冷。
I hope he will come, too. 我希望他也能来。
(2)wish可以接sb. to do sth. 的结构，而hope不可以。例如：
Do you wish me to come back later? 你是否希望我再来？
4. be sure to do sth./ be sure of/about sb. or sth.
