Michael likes Chinese food very much. (2)当句子为否定句时,要根据主语的人称来决定使用相应的助动词:当主语为"三单"时,要使用does;当主语为"非三单"时,用助动词原形do。例如把下列句子变否定句: Kangkang likes math.----Kangkang doesn't like math. They like sports.------They don't like sports. (3)当句子变疑问句时,同样要根据句子的主语来决定在句首使用Do或Does.例如下列句子变问句: Michael likes Chinese Food.----Does Michael like Chinese food? Yes, he does./ No, he doesn't. Jane and Helen like music.----Do Jand and Helen like music? Yes, they do./ No, they don't. 十、名词所有格 1、Kangkang's books;Tom and Helen's desk; Ann's and Maria's bikes; 2、用of表示"......的",但要从of后往of前翻译:a book of mine(我的一本书) 3、have与of的区别: have一般表示"主动拥有",往往用于有生命的人或动物;无生命的物体一般不能"主动拥有",表示所属关系时要用of。例如: I have a new bike. She has two big eyes. a door of the house 十一、初一英语上册知识点之课本中的知识点 1、Unit 1 --Unit 2 (1)问候语: Good morning/ afternoon/ evening. How are you?---Just OK, thank you. How are you?---Not bad, thanks. Hi!
