一、语法解析
(一)情态动词
情态动词本身有一定含义，但不能单独使用，为谓语动词增添情态色彩。表示说话人对有关行为或事物的态度和看法，认为有可能，应该或有必要等。情态动词无人称和数的变化。其后接的动词为原形。否定形式在情态动词后加not，在表达可能发生某事时，用 may/might.
Eg: You may/ might be right.
你也许是对的。
1.情态动词may和might
may译为"也许，可能"，表示主观判断不十分肯定的可能性。
may与might没有太大的区别，形式上might是 may的过去式，但在表示将来的可能情况时， might表示可能性比may的可能性小。
Eg: They may come tomorrow.
他们明天可能会来。
There might be some rain tomorrow morning.
明天早上可能有雨。
2.情态动词can
(1)表示能力："能；会"
Eg:Tony can speak Chinese.

Eg: You can use my pen.
你可以用我的钢笔。
Can I come in
我可以进来吗
You can't park your car here.
你不可以把你的车停在这。
3.情态动词must
must译为"必须"表示说话者主观上认为有必要或有义务去做某事。
其否定形式mustn't,"一定不要；不准；必须".
Eg: You must get there before 5 o'clock.
你必须5点前到那。
You mustn't break the rules.
不准你违反规则。
注意：以must开头的一般疑问句，肯定回答用 must，否定回答为needn't或don't have to，译为"不必"
Eg: -- Must I stay here after school
我必须放学后呆在这吗
-- No, you needn't./ No, you don't have to.
不，不必。
4.情态动词need
need"需要"常用于否定句或疑问句中，否定形式为needn't，译为"不需要；不必要".

An Unforgettable Day
As the saying goes, "Roses given, fragrance in hand." In our daily life, it is necessary for us to help those who are in need of help. Here's my unforgettable day of helping others.
My classmate Jason was ill in hospital last week. I made up my mind to help him. Yesterday was Saturday, and my classmates and I went to see him together. We gave him some flowers to make him feel good and happy. Jason asked me some questions about study and I brought him my
notebooks. I was patient to answer his questions all the time. Jason was so moved and decided to help others later.
I think helping others not only makes us happy but also brings to love to others. Love leads to love, and so creates a circle of goodwill and kindness.
Thanks!
