1、不定代词代词教案不定代词适用学科英语适用年级初中一年级适用区域北京 课时时长（分钟）60知识点不定代词教学目标掌握不定代词的形式及用法教学重点不定代词的形式及用法教学难点不定代词的形式及用法一、复习预习 代词是代替名词及起名词作用的短语或句子的词。代词根据其意思和用法可分为人称代词、物主代词、反身代词、指示代词、相互代词、疑问代词、连接代词、关系代词、不定代词九类。 2、知识讲解知识点：【考查点1】 复合不定代词 由some; any; no; every和body; thing; one构成的合成词 考点要求1. 自身的意义以及对句式的要求：构成复合不定代词的两个部分分别表示不同的意义和对句

2、式的要求以及考虑其表人还是表物。 body用来表人；thing用来表物；one既可表人也可表物。 some表示“某”，用于肯定陈述句或用情态动词引导的问句中； any表示“某”，用于否定句或问句； no表示“没有”，用于肯定句说明否定意义； every表示“每一”，用于肯定句或问句。2. 主谓一致性关系：复合不定代词任何时候都看为单数，作主语时，谓语动词使用第三人称单数形式。 e.g 错：Everybody in our class are interested in English. 对：Everybody in our class is interested in English.3. 定

3、语后置关系：对复合不定代词进行修饰的词语必须后置放在它的后面。 e.g 错：I have important something to tell you. 对：I have something important to tell you.4. none和其它复合不定代词的用法区别：none在句中不能单独作主语，但可同of连用带名词一起作主语；其它复合不定代词可单独作主语，但不能同of连用。 e.g 错：He is new here, so none knows him. 对：He is new here, so no one knows him. 错：Nobody of them has be

4、en to England before. 对：None of them has been to England before.5. 代换复合不定代词的人称代词：在使用人称代词代换复合不定代词时，应考虑其表人还是表物，表人时，用they代换，表物时，用it代换。 e.g Something is wrong with your computer, isnt it? Nobody has been there before, have they?【考查点2】不定代词用于代换上文中可数名词的all, both, each, either, none, neither ( every)等表示不定概念

5、的词语 考点要求1. 考虑表示“两者”还是“两者以上”：选用不定代词时，首先应根据上下文的关联以及句中某个关键词语对不定代词的限制，考虑其说明“两者”还是“两者以上”的人或物。 如说明“两者”，选用both、either、each或neither。 如说明“两者以上”，选用all、（every）、each或none。 e.g. The twin sisters are both good at math. None of the students in our class wants to go there.2. 考虑表示肯定还是否定：选用不定代词时，还应根据句子意义考虑应该使用表肯定的词语还

6、是表否定的词语。如说明肯定，使用all、both、either、each或（every）。 如说明否定，使用neither或none。 e.g. None of us wants more because we are all full. 3. 考虑作限定词使用时同名词的关系：除none以外的不定代词都可用作限定词，其后所带的名词应考虑使用适当的形式。 all可带复数可数名词或不可数名词；both只能带复数可数名词；either、neither、each、every只能带单数可数名词。不定代词作限定词使用时，用来表示总量关系，为前位限定词，应放在整个名词词组的最前面，其中all、both可同中

7、位限定词和数词连用，但either、neither、each、every作限定词时，同其余限定词相排斥。 e.g All the students in our class are going to take part in the sports meeting. Every boy in our class is going swimming this afternoon.4. 考虑作主语时主谓一致性关系：不定代词作主语时，应考虑其说明单数还是复数，以便确定谓语动词是否应使用第三人称单数形式（-s形式）以及be动词使用单数还是复数。both和all作主语时，看作复数，谓语动词不用-s形式，b

8、e动词用复数形式；either、each、neither单独作主语时，看作单数，谓语动词用-s形式，be动词用单数形式；either、each、neither、none同of一起构成词组作主语时，如of后带人称代词，一般将其看为单数，如of后带复数名词，既可看为单数，也可看作复数（初中英语中常看作单数）。e.g All of the students are going hiking next weekend. Both of the twin brothers have been there several times. None of them is going to the movie

9、tonight. Neither of the boys is / are going to watch the football match this afternoon.5、不定代词作同位语时的位置关系：不定代词作主语同位语时，应放在谓语动词前，特殊动词（情态动词、助动词）后；作宾语同位语时，应紧跟在宾语后。e.g The students all went to the movie except Mike. We will all go to Beijing for vacation this summer. Its necessary for us all to learn Engli

10、sh well. Then mix it all up.【考查点3】 other的用法：other, another, others, the other, the others的用法区别基本用法 other：形容词，其后可带复数名词，如带单数可数名词，其前应加上适当的限定词； another：限定词，其后带单数可数名词；代词，代换上文中提及的可数名词（单数，泛指）； the other：限定词，其后可带名词；代词，代换上文中提及的可数名词（单数，定指）； others：代词，其后不能带名词，代换上文中提及的可数名词（复数，泛指）； the others：代词，其后不能带名词，代换上文中提及的

11、可数名词（复数，定指）； 注意：限定词同名词之间只能使用other。考点要求 注意两个句式、一个搭配和两个区别1、两个句式的用法（1）One the other 一个 另一个注意：使用该句式时，其前应出现说明具体数量的数词two；如出现的数词大于two，one可以根据实际情况调整成其它数词；如出现的数词减去one或调整后的数词后仍大于“1”时，the other应变为the others或“the other + 数词”（两个数词相加应等于所给数词）。 e.g There are two apples here. One is for you, the other is for your si

12、ster. There are five apples here. Two are for you, the others are for your sister. There are five apples here. Two are for you, the other three are for your sister.（2）Some others 一些 另一些 注意：使用该句式时，其前应出现说明不定数量的词语；如出现说明具体数量的数词，others前应加上the。 e.g There are many people on the beach. Some are swimming, ot

13、hers are enjoying the sun. Mrs. Smith bought 25 books. Some were for her daughter, the others were for her son. 2、一个搭配：any同other连用时应注意之点： Any others：any同单一的other连用，other应使用others； Any other + 单数名词：any后如还带有名词，用other，名词用单数； Any of结构：any of后的other前应加the，如含名词用other，名词用复数；如不含名词，用others。 e.g Of all the ci

14、ties in China, Shanghai is bigger than any others. Of all the cities in China, Shanghai is bigger than any other city. Of all the cities in China, Shanghai is bigger than any of the others. Of all the cities in China, Shanghai is bigger than any of the other cities. 3、两个区别： （1）同数词连用时another和more的区别a

15、nother用于数词前，more用于数词后。 e.g To finish the work in time, we need another two men. To finish the work in time, we need two more men.（2）other和else的区别Other用于名词前；else用于wh-词或复合不定代词后，其后不能带名词。e.g What other animals do you like? Do you have anything else to tell us? What else did you buy last week?4、初中英语中除上述情
