Lesson 3-4 Sorry, sir I like apples. 主格（用于句首） You love me . 动词 宾格（用于动词后面） This is my book.（名词） 所有格（用于名词前） I am he/she/it is be动词 (第三人称单数） we /you/they are 一般疑问句 Is this your handbag? 肯定回答： Yes ,it is. 否定回答： No , it isn’t. 什么叫一般疑问句？ 由yes 和 no 来回答的句子叫一般疑问句。 这是一匹马吗？ 是的，它是。 Is this a horse? Yes ,it is. 注意： 句中含有am,is ,are （be动词）， 变一般疑问句，把am,is,are （be动词）提前 Does the man get his umbrella? 第三人称单数 Yes , he does. 注意： 当句中没有be动词（am,is,are)的时候，变一般疑问句就要在句首加do,如果主语是第三人称单数就要加does.动词改为原型。 eg. You like the book. Do you like the book? He likes the book. Does he like the book? I can swim. 我能游泳吗？？ 是的，我能。/不，我不能。 Can you swim? Yes ,I can ./ No ,I can’t. 注意： 当句中含有情态动词can的时候，变疑问句，把can提前。 A:My coat and my umbrella please. Here is my ticket. B:Thank you,sir. Number five. Heres your umbrella and your coat. A:This is not my umbrella. B:Sorry, sir. Is this your umbrella? A:No, it isnt. B:Is this it? A:Yes, it is. Thank you very much. pen pencil book watch coat dress skirt shirt car house suit school teacher son daughter 语法点 Be 动词 就近原则 be动词用法歌： 我用am,你用are，is连接他，她，它。 单数名词用is，复数名词全用are。 变疑问，往前提，句末问号莫丢弃。 变否定，更容易，be后not莫忘记。 疑问否定任你变，句首大写莫迟疑。 一、在下面的短文中填上恰当be动词。 I ______ a girl.
