31、ake？can 用在否定句和疑问句中时有时表示说话人的 “猜测”或 “不肯定”。例如：Canthenewsbetrue？(在日常会话中， can 可代替 may 表示 “允许 ”，may 比较正式 )could 是can 的过去式，表示过去有过的能力和可能性，还有怀疑和不肯定的意思(在否定和疑问句中 )。例如：Thedoctorsaidhecouldhelphim(能力)At that time we thought the story could be true(可能性 )could 用来提问 ， 是 有 礼 貌 的 请 求Could. Please? 语 气 较 为 婉 转 。 例 如 ：

32、CouldIspeaktoMr.Smith,please?2、 might 也是 may 的过去式 ,其用法如下 :may的用法:a. 表示”允许”或”请求”例如：May I come in ？在使用这一用法时需注意 : may 表示 “允许 ”的否定形式是 must not，意思是“不应该”“不许可”。例 如 ： MayItakethisbookoutofthereading-room ？No，you mustn't b. 表示说话人的猜测，认为某一事情”或许”或”可能”发生。例如：Hemayknowtheanswerc. may用在感叹句中可表示祝愿、愿望。例如：Mayyousuc

33、ceed (祝你成功。)might的用法:a. might 可以代替may，表示现在时间的动作，但语气较为婉转客气或更加不肯定。例如： He might not come todayb. might 用来表示现在时间时，还可表示”规劝”。例如： You might pay more attention to spoken English3、must与 have to的区别have to 比较强调客观需要， must 着重说明主观看法。另外have to 能用于更多时态，比较下面的句子：We had to be there at ten有时两者都可以用，意思差别不大。例如： We must ha

34、ve to leave nowmust 在表示说话人对事物的推测时候要7/19注意它比 may 肯定得多，相当于汉语的“一定”或“准是”。(只有在肯定句中能这样用。)There must be a mistake 在回答由 must 引起的问题时，如果是否定的答复，不能用 mustn't，而需要用 needn't 或 don't have to，因为 mustn't 是“一定不要”的意思。例如：Mustwehandinourexercisestoday？ No， you needn't must not 的否定形式则表示“不应该”或不许可”，语气比较强烈

35、。例如： You mustn't play on the road4、belong to someone和 be someones的用法区别。两者都表示“需要某人”“归某人所有”，但 belong to中的 to 为介词，后需接名词或宾格代词be someones中 be 动词，需接名词的所有格形式和名词性物主代词。【例如】 1） The English book belongs to Tom。2）The English book is Toms3）The English book belongs to me。4）The English book is mine。5、much too、

36、 too much的区别。much too表示“太 ”，后接形容词或副词例如： The question is much too difficult for me。too much表示“太多的 ”，后面一般接不可数名词，例如： I have too much homework to do6、because为连词，表示原因，后面必须接句子。例如： I cant go out because it is raining now。而 because of 也表示原因，但 of 为介词，所以后面一般接名词、代词或动名词。例如： I cant go out because of the rain。7 t

37、ry to do 表示“竭尽全力去做 ”，强调付出了一定的努力。例如： I tried to look for my lost pen，but Ifailed 。try doing 表示“尝试 /试图做 ” 强调只是试一试，不一定付出了努力。例如： I tried chatting with him 。 Luckily， he was on line。专项练习检测：单项选择1.
