【要点1】指示代词有this，that，these，thse等。This,thse在一些句子中代替前面的名词以避免重复,如：The weather in Beijing is clder than that in Guangzhu. 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 ther;和ne anther两组，但在运用中，这两组词没什么区别。 如： They lve each ther. 他们彼此相爱。
【要点3】反身代词:myself/urselves,yurself/yurselves,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 t herself. 她自言自语。初中阶段常用的短语有 teach neself自学,dress neself 自己穿衣，cme t neself 恢复知觉，enjy neself 过的快活， help neself t 随便吃、随便用，make yuself at hme 不受约束，by neself 独自地; 单独地，speak t neself 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，bth，each，every等，以及含有sme-，any-，n-等的合成代词，如anybdy， smething，n ne。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nne和由sme，any，n等构成的复合不定代词只能作主语、宾语或表语；every和n只能作定语。e.g： --- D yu have a car? --你有一辆小汽车吗？ --- Yes，I have ne. --是的，我有一辆。 --- I dn’t knw any f 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bth,all,either,any,neither,nne等，这是代词考查的重点。bth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r 连用；any指三者或三者以上中任一个；neither意为“两者都不”；nne 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 tw sns，but _____ f them lks like me. A bth B. nne 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：Lk at the pht,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 yu sme questins, Dr. Li? --- Sure, g ahead.1) 固定搭配：ask questins 问问题 拓展：slve prblems 解决问题2) G ahead. (口语)进行吧！干吧！请吧！ ahead 意思是向前，这里的g ahead原意为向前走，在这里译作继续问问题，相当于g n。 如: --- May I start?  我可以开始了吗？ --- Yes, g ahead.   好，开始吧。
2. S what shuld we d t prevent it? 那么我们该做什么来预防它呢？ 1）不定式短语t prevent it表示前面某个行动的目的。2）prevent sb. (frm) ding sth. 阻止某人做某事，此处frm可省略。 stp keep sb. frm ding sth. 阻止某人做某事，此处frm不可省略。
