初一英语上册语法知识点2

  冠词的用法(名词前面必须要有冠词)

  冠词分为定冠词(the)和不定冠词(a, an)两种。

  1、定冠词the表示"特指",可译为"这个"、"那个"、"这些"、"那些"。

  2、不定冠词a, an用来表明(可数)名词的数量是"一个"。an用于以元音开头(注意不是以元音字母开头)的单词前,a则英语非元音开头的单词前。

  3、不定冠词a, an与基数词one的区别是:不定冠词不是刻意强调"数量",而基数词则强调"数量"。

  助动词(do, does )的用法

  只有实意动词作谓语时才涉及使用助动词。以like为例:

  (1)当句子为肯定句时不涉及使用助动词,只涉及"主谓一致"原则。

  eg : I like English a lot.

  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.

  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
