代词指代一．概述代词指代的概念：在英语表达中，为避免用词重复和使句子简洁，经常使用一个代词指代前面出现过的名词（先行项）。
代词分为8类：人称代词、物主代词、反身代词、指示代词、疑问代词、不定代词、关系代词和相互代词1.2. 指示代词：this, those, that, those, one, it3. 疑问代词：what, who, whose, whom, which, whatever, whichever ,whoever, whomever4. 不定代词：some（something，somebody，someone），any（anything，anybody，anyone），no（nothing，nobody，no one），every（everything，everybody，everyone），all，each，both，much，many，（a）little，（a）few，other（s），another，none，one，either，neither5. 相互代词：each other，one another6. 关系代词：关系代词用来引导定语从句。
它代表先行词，同时在从句中作一定的句子成分。
二．记牢四点：1、代词与其先行项保持“数”的一致：代词的单复数由其先行项决定，同单同复。
如：Some teenagers adore computer games , so others condemn it as an utter waste time.2、代词与其先行项要保持“性”的一致：代词的“性别”由其先行项的“性别”决定，同男同女。
如：When Lucy visited the restaurant, he noticed that the menu had changed.3、代词与其先行项要保持“人称”的一致：代词的人称形式由其先行项的人称形式决定，同我同你同他。
如：Because each year our children spending increasingly more time in front of computer monitors , you need to limit their viewing hours and encourage them to go outdoors and play.4、注意代词的格代词的“格”是指代词的主格、宾格和所有格。
代词用什么“格”看它指代的先行项在句中是什么成分。
三、代词指代一致必须注意以下几个原则和规律：1、邻近和靠近原则在either … or，neither…nor，not only…but (also)中，如果两个先行词在数或性上不一致，人称代词一般与邻近的先行词在数和性上保持一致。
Neither Mary nor Alice has her key with her.Neither the package nor the letters have reached their destination .If either David or Janet comes, he or she will want a drink .2.当不定代词作主语时候，其相应的代词一般用第三人称单数形式。
如：Everyone talks at the top of his vo0ice.Everything is ready, isn’t it?3.当主语为复数形式，后跟each作同位语时，如果each位于动词之前，其后的代词或相应的限定词用复数形式;如果each位于动词之后，其后的代词或相应的限定词用单数形式。
如：We are each responsible for his own family .4.由and连接两个先行词，代词用复数如：The tourist and businessmen lost their luggage in the accident .注：1. Sat不接受前面出现两个名词（同为女性、男性或复数人称，即使指代的对象很明确）Mary told her mom that she was pregnant.After years of research on the dogs and wolves, scientists are confident that their resemblance is obvious.2.sat不接受“暗示指代”They say Mary is a nice girl.3.普通文法中，Which可指代前面整个句子（前加逗号），但sat不接受Mary came home late last night, which upset us a lot.练习I.
