18、m. 代 词 人称代词 一、概念 人称代词是表示我、你、他/她/它、我们、你们和们的词。人称代词有人称、格 1一般情况下,人称代词的主格作主语,放在句子的开头。 I am a teacher. 我是一名教师。 You are 10 years old. 你10岁了。 He is my friend. 他是我的朋友。 It is hot today. 今天天气热。宾格作宾语,通常放在动词,如:let, like, help,give,ask等的后面;或介词,如:for, to, of,at等的后面。 Lets go . Can you help me?你能帮我吗? The cake is for
19、 you.这个蛋糕是给你的。 在简短对话中,当人称代词单独使用或用在not后,多用宾格。 -I like English.-Me too. -Who broke the window?-Me. Why not me?作表语,口语中常用宾格 -Who is that?-Its me. 是谁啊?是我。 三、注意 1人称代词I无论放在句首、句中或句尾,都要大写。 2人称代词she除了指女性“她”之外,还可以指祖国、月亮等拟人的东西。表示一种亲密或爱抚的感情。 如:I love my country. She is great. The moon is in the sky. She is round
20、 and bright. 四、It的特殊用法 1一般情况下,it表示人以外的动物和东西,是单数名词的代词,译为“它”。 Where is your car?It is over there. 你的小汽车在哪儿?在那边。但在表示天气、时间、距离等时,用it来代替,此时的it,并不译为“它”。 1)指天气:It is sunny today. 今天阳光灿烂。 2)指气候:Its cold in this room. 这个房间很冷。 3)指时间:What time is it?Its six thirty. 几点了?六点半了。 4)指距离:How far is it from here to the
21、 park? 从这儿到公园有多远?Its about two miles. 大约是二英里。 3“ it ” 有时也可指人。 Its me. Open the door, please. 五、并列人称代词的排列顺序: 1、单数人称代词并列作主语时,其顺序为:第二人称第三人称第人称 如:you,he,and I 2、复数人称代词并列作主语时,其顺序为:第一人称第二人称第三人称 weyouthey 注意:如果是做错事,承担责任时,说话的人把I放在第一位。 Who broke the window?谁打碎了玻璃?I and Li Ming.我和李明. 物主代词 表示所有关系的代词叫做物主代词,也可叫做
22、代词所有格。物主代词分形容性物主代词和名词 性物主代词二种,物主代词也有人称和数的变化,见下表: 如:I love my country. 而名词性物主代词 /Jims /Toms/Marias This is her book. = This book is hers. 指示代词 表示“这个”、“那个”、“这些”、“那些”等指示概念的代词叫做指示代词。指示代词有this,that,these,those等。 this,是指在时间上或空间上离说话人较近的人或物。 that,是指在时间上或空间上离说话人较远的人或物。 This girl is Mary. Those men are my tea
23、chers. I am busy these days. That is a red car. What do you like? I like this. 反身代词 如: She was talking to herself. 她自言自语。 I am teaching myself computer. 我自学计算机。 Take good care of yourself. 把自己照顾好。 You should ask the children themselves. 你应该问一问孩子们自己。Enjoy yourself.玩的愉快。 人称代词口诀:I 是主格 me 是宾,请你一定记在心;主格用
24、在动词前,动词介词后用宾。 you 是主格,也是宾,; he 是主格 him 是宾, she 是主格 her 是宾, it 是主格,也是宾, we 是主格 us 是宾, you 是主格,也是宾, they 是主格 them 是宾。 相关练习题 一、填写下面的表格。 二、用人称代词代替下单词或词组。 1Mike the rabbit Mr White Miss White Tom and I Kate,Tim and I Joan and John Joans mother My father 10their brother 三、选词填空。 1. _ will spend the summer
