Please? 语气较为婉转。例如： Could I speak to Mr. 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：May I take this book out of the reading-room？ No，you mustnt b. 表示说话人的猜测，认为某一事情”或许”或”可能”发生。例如： He may know the answer c. may用在感叹句中可表示祝愿、愿望。例如：May you succeed(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 have to leave nowmust在表示说话人对事物的推测时候要注意它比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mustnt，而需要用neednt 或dont have to，因为mustnt是“一定不要”的意思。例如：Must we hand in our exercises today？ No，you neednt must not的否定形式则表示“不应该”或不许可”，语气比较强烈。例如： You mustnt 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 Tom，s3）The English book belongs to me。4）The English book is mine。5、much too 、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 do 6、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 try 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The football may _John.
