I enjoy reading the books of Robert Louis Stevenson because I find them really exciting. 我喜欢读罗伯特·路易斯·史蒂文森的书，因为我觉得它们很有趣。 一、考点 1. 疑问词+动词不定式的用法 1).疑问词＋不定式结构中的疑问词，包括疑问代词who, what, which和疑问副词how, when, where等.这些疑问词和不定式一起构成了不定式短语,这种结构可在句子中作主语、宾语、表语等.例句： How to do it is a question. 该怎样做倒是一个问题。（作主语） I really don't know what to write about. 我实在不知道该写些什么。（作动词宾语） We must first solve the problem of whom to serve. 我们必须首先解决为谁服务的问题。（作介词宾语） The question is where to put it. 问题是该把它放在哪儿才好。（作表语） I asked him how to learn English. 我问他如何学习英语。（作宾语补足语） 2). 疑问词＋不定式结构相当于一个名词性从句，常常可用同等成分的从句代替。改写时只需在疑问词后加一适当主语，并将不定式改成适当形式的谓语。上述例句可以分别改写成： How we should do it is a question. I really don't know what I should write about. We must first solve the problem of whom we should serve. 7 / 17 【本资料精心搜集整理而来，欢迎广大同仁惠存！】 The question is where we should put it. I asked him how we should learn English. 3).疑问词＋不定式结构经常放在tell, show, teach, learn, know, wonder, discuss, remember, forget, find out等动词（词组）之后作宾语。 例句： The teacher told the students how to do the experiment. 老师教学生如何做实验。（句中 told含有taught的意思） The young woman doesn't know what to do. 那位年轻女子不知道怎么办。（句中what不能改换成how） He tells me how to answer all the questions in English. 他告诉我怎样用英语回答所有的问题。（句中的how不能省去） 另外，这种结构可以构成独立问句。 例句： What to do? 怎么办? How to get rid of the trouble? 如何摆脱困境? 2. must和have to的用法区别 1). 强调重点不同 两者都表示必须，但must 侧重于说话者的主观看法,认为有必要或有义务去做某事；have to 则重于客观需要,含有不得不或被迫之意。 例句： We must go at once. 我们必须马上就走. If I buy that car, I have to borrow some money. 如果我要买那辆汽车,我得借些钱. 2). 时态形式不同 8 / 17 【本资料精心搜集整理而来，欢迎广大同仁惠存！】
