情态动词can和may和must的用法详解解析
(1)can、be able to 和could
①can和be able to都表示能力,意思上没多大区别。但can只有现在和过去时,而be able to则有更多的形式。但当成功地完成某一具体动作时,通常不用could而用was/were able to来表示。这时was/were able to 相当于managed to,表示经过一番努力,终于能够完成某事。如:
Can you use chopsticks?
The wounded man still was able to get to the village and was saved in the end.
②can和could
can和could都可以表示能力、技能、许可、建议或请求和可能性。但比较委婉客气地提出问题或陈述看法,一般用could,回答时则用can。如:
Could you help me carry the bag?
Can I help you?
(2)may/might
①may/might表示可能,但may比might可能性大。
Eg.---Why isn’t he in class?

    ---- He may be sick.(生病的可能性较大)

囧记单词
速记英语单词
单词不用记

 ---- He might be sick.(生病的可能性较小)
②may/might表示“允许”,may用于现在时或将来时,might常用在间接引语中表过去时,但might也可用于现在时间,表示比较委婉的语气,回答用may。如:
He says we may leave.
He said we might leave.
③may / might 表示建议或请求,但might比may 更客气,意思更肯定而无过去时态的含义。
—May / Might I use your bike?   
—Yes, you can / may.
----No, you mustn’t
(3)must
①must表示必须,应该,没有时态变化。如:
You must do everything as I do.
②must表示肯定的推测。如:
The light is still on, so he must be at home.
③mustn’t 表示禁止做某事。如:
You mustn’t smoke in the office.
(4)have to
have to 表示“必须、不得不”,是由于某种外界(客观)原因而“必须”,“不得不”做某事,也可表示经常的或习惯性的事“必须”做。have to的否定形式表示不必。have to可用于多种时态中。如:
You will have to clean your own boots when you join the army.
I have to be at my office every evening.

To forgive is a virtue(美德), but no one has ever said it is easy. When someone has deeply hurt you, it can be extremely difficult to let go of your hate. However, forgiveness is possible, and it can be surprisingly beneficial to your physical and mental health. People who forgive show less sadness, anger and stress and more hopefulness, according to a recent research.
   36Try the following steps:
Calm yourself.    37You can take a couple of breaths and think of something that gives you pleasure: a beautiful scene in nature, or someone you love.
Don’t wait for an apology. Many times the person who hurt you does not intend to apologize. They may have wanted to hurt you or they just don’t see things the same way.    38Keep in mind that forgiveness does not necessarily mean becoming friends again with the person who upset you.
Take the control away from your offender(冒犯者). Rethinking about your hurt gives power to the person who causes you pain. Instead of focusing on your wounded feelings, learn to look for the love, beauty and kindness around you.
   39If you understand your offender, you may realize that he or she was acting out of unawareness, fear and even love. You may want to write a letter to yourself from your offender’s point of view.
Don’t forget to forgive yourself.    40But it can rob you of your self-confidence if you don’t do it.
A. Why should you forgive?
B. How should you start to forgive?
C. Recognize the benefits of forgiveness.
D. Try to see things from your offender’s angle(角度)
E. For some people, forgiving themselves is the biggest challenge.
F. To make your anger die away, try a simple stress-management technique.
G. If you wait for people to apologize, you could be waiting an awfully long time.
