can和could的区别和用法
1. can表示体力和脑力方面的能力， 或根据客观条件能做某种动作的“能力”。 例如：
Can you speak English 　　
Can you make a cake
　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”。
Can the news be true
　(在日常会话中，can可代替may表示“允许”，may比较正式。)
2. 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)。
She couldn’t skate when she was five years old.　 （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。
Could I speak to Mr. Smith, please
might和may的区别和用法:
1. may的用法:
　 a. 表示“允许”或“请求”。
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”。
—May I take this book out of the reading-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。
He may know the answer．
c. may用在感叹句中可表示祝愿、愿望。
May you succeed．(祝你成功。)
May you have a pleasant journey．(一路平安。)
2. 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。
Might I take a suggestion？
b. might用来表示现在时间时，还可表示“规劝”。
You might pay more attention to spoken English．
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 10:00.
有时两者都可以用，意思差别不大。
We must /have to leave now.
must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“是”。(只有在肯定句中能这样用。) This must be your room．
　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。
