语法+写作解析
一、语法解析
(一)疑问词+动词不定式
"疑问词+动词不定式"构成不定式短语，相当于一个名词性短语，在句中用作主语，宾语，表语等。但疑问词why后不能跟动词不定式。
Eg: When to have a sports meeting is still a problem.
何时举办运动会还是个问题。(作主语)
I haven't decided what to eat for lunch.
我还没有决定午饭吃什么。(作宾语)
The question is how to learn English well.
问题是怎么学好英语。(作表语)
注意：有些疑问词，如what,which,whose, how many,how much等，气候可以先接一个名词，再接动词不定式。
Eg: My mum is checking how much money to spend.
我妈妈在盘算该花多少钱。
(二)must与have to
1.must是情态动词，译为"必须，一定要"，后接动词原形，可用于肯定句，否定句或疑问句。 must的否定形式must not(mustn't)语气较为强烈，译为"不许，禁止";must还可表示把握性很大的肯定猜测，译为"一定，准是"。
Eg: I must finish the work before dinner.
我必须在晚饭前完成这项工作。
You mustn't swim in the lake.
你不准在湖里游泳。
The light is on. He must be at home.
灯亮着，他一定在家。
注意：(1)将含有must的句子变为否定句时，要讲must变为can't.
Eg:He must be Mr.Li. 他一定是李先生。
--He can't be Mr.Li. 他不可能是李先生。
(2)如果must用于疑问句，否定回答应该用 needn't或don't have to，而不是mustn't.
Eg: Must I finish the work now
我一定要现在完成这项工作吗
肯定回答：Yes, you must.
否定回答：No, you needn't./ No, you don't have to.
2.have to译为"必须，不得不"，后接动词原形，表示在客观上有必要做某事。
注意：(1)have to有一般现在时，一般过去时和一般将来时等多种时态。
Eg: Sandy had to wait at the park gate yesterday morning.
昨天早上桑迪不得不在公园门口等候。
(2)构成一般疑问句时，要在句子开头加 do,does,did或will等助动词。
Eg: Will they have to speak English in Canada
在加拿大他们必须讲英语吗
(3)have to的否定形式don't/ doesn't/ won't have to表示"没有必要".
Eg: You don't have to answer the question.
你没有必要回答这个问题。
3.must与have to区别：
must侧重于说话者的主观看法；have to侧重于客观需要；
Eg: Everyone must wear seat belts.
每个人都必须系安全带。
His bike was broken yesterday, so he had to walk to school.
昨天他的自行车坏了，所以他不得不步行去学校。
must没有人称，数和时态的变化；have to有人称，数和时态的变化。
Eg: He must be back by ten o'clock.
他必须10点之前回来。
He has to help his parents on the farm.
他不得不在农场里帮助父母。

My favourite book is Journey to the West. It is one of the four Chinese literary classics. It was written by Wu Cheng'en.
The book tells us about stories of four main characters. After getting over many difficulties on the way to the West, finally they made it. Among the four characters, the Monkey King is my favourite. He is so smart and brave that he can protect others well. He never gives up when he faces difficulties and challenges.
The book has taught me not to give up or doubt myself. I have read the
book several times, I'm not tired of it. If you have never read Wu Cheng'en, I recommend the book to you.
That's all. Thank you.
