花费时间金钱等
【要点1】指示代词有this，that，these，those等。This,those在一些句子中代替前面的名词以避免重复,如：The weather in Beijing is colder than that in Guangzhou. 这种题型经常在考试中出现。
【要点2】相互代词是表示相互关系的代词，有each other;和one another两组，但在运用中，这两组词没什么区别。 如： They love each other. 他们彼此相爱。
语法学一学
代词
【要点3】反身代词:myself/ourselves,yourself/yourselves,herself/ himself/itself/themselves、反身代词是表示"我自己"、"你自己"、"他自己"、"我们自己"、"你们自己"和"他们自己"等的代词，也叫做自身代词。　反身代词的基本用法:可以在句中作宾语、表语、同位语等,表示“独自,亲自变化规则：一二人称在形容性物主代词后加self（单数）或selves （复数）。第三人称在宾格后加 self（单数）或selves （复数）。 如： She was talking to herself. 她自言自语。初中阶段常用的短语有 teach oneself自学,dress oneself 自己穿衣，come to oneself 恢复知觉，enjoy oneself 过的快活， help oneself to 随便吃、随便用，make youself at home 不受约束，by oneself 独自地; 单独地，speak to oneself 自言自语
【要点4】不定代词指不是指明代替任何特定名词的代词。常见的不定代词有a11，both，each，every等，以及含有some-，any-，no-等的合成代词，如anybody， something，no one。这些不定代词大都可以代替名词和形容词，在句中作主语、宾语、表语和定语， 但none和由some，any，no等构成的复合不定代词只能作主语、宾语或表语；every和no只能作定语。
e.g： --- Do you have a car --你有一辆小汽车吗？ --- Yes，I have one. --是的，我有一辆。
--- I don’t know any of them. 他们，我一个也不认识。
常见考法
对于代词的考察，通常是以单项选择或完形填空形式考查代词词义及其用法，尤其是几个易混淆的代词，如every和 each，前者用于三个或三个以上，不能与连用，后者用于两个或两个以上，可以和连用。
误区提醒
1.准确使用不定代词both,all,either,any,neither,none等，这是代词考查的重点。both表示“两者都”；all表示“三者或三者以上都”；either指两者之间任何一个，常与or 连用；any指三者或三者以上中任一个；neither意为“两者都不”；none 指三者或三者以上都不。
2.形容词修饰复合不定代词需要后置。
3.准确使用人称代词宾格、物主代词、反身代词。
典例 1：I have two sons，but _____ of them looks like me.
A both B. none C. neither D. every
【答案】C
【解析】 本题考查不定代词的用法。B和D都用于三者或三者以上，故排除；表示转折，说明“两个儿子都不像我”，neither意为“两者都不”，故用C。
典例 2：Look at the photo,the girl beside--- is Nancy.
A I B my C me D mine
【答案】B
【解析】本题考查人称代词用法，介词后加宾语。
1. --- May I ask you some questions, Dr. Li
--- Sure, go ahead.
1) 固定搭配：ask questions 问问题
拓展：solve problems 解决问题
2) Go ahead. (口语)进行吧！干吧！请吧！
ahead 意思是向前，这里的go ahead原意为向前走，在这里译作继续问问题，相当于go on。
如: --- May I start 我可以开始了吗？
--- Yes, go ahead. 好，开始吧。
