七年级英语下册知识点整理

①Ｓｈｅdoesn't have ａｎｅｗｐｅｎ．她没有一枝新钢笔。

②Tｈｅｙ don't have ｌｕｎｃｈａｔｈｏｍｅ．他们不在家吃午饭。

③Ｉ don't have ａｂｒｏｔｈｅｒ．我没有一个弟弟。

肯定句变成一般疑问句需要用助动词do/does，即一般疑问句为“Do/Does+主语＋have＋其他”。

所以以上三句的一般疑问句形式依次为:

① Does sｈｅhave ａｎｅｗｐｅｎ她有一枝新钢笔吗? Yes，she does./Ｎｏ,she doesn't．

②Do they have lun at home？他们在家吃午饭吗？Yes，ｔｈｅｙｄｏ．/Ｎｏ，ｔｈｅｙｄｏｎ'ｔ．

③Do you ｈａｖｅａｂｒｏｔｈｅr？你有一个弟弟吗？Yes，Ｉｄｏ．/Ｎｏ，Ｉｄｏｎ'ｔ．

（．3．）实义动词

．．．．．（表示人或动物动作的动词即行为动词

．．．．）的一般现在时

肯定句由“主语＋动词原形（ｓ／ｅｓ）”构成。（注意：只有在主语为第三人称单数的情况下，动词原形

后面才加ｓ／ｅｓ）。

例如：①I do homework every day.我每天都做作业。②He watches．． TV every evening.他每晚都看电视。

肯定句变成否定句需要用助动词don't/doesn't，即由“主语＋don't/doesn't+动词原形”构成。

以上三句的否定句依次为：①Idon't do homework every day.我每天不做作业。

②He doesn't watch TV every evening.他每晚不看电视。

肯定句变成一般疑问句需要用助动词do/does，即一般疑问句为“Do/Does +主语＋动词原形”。所以

以上三句的一般疑问句形式依次为：

①Do you do homework every day？你每天都做作业吗？Yes，Ｉｄｏ．/Ｎｏ，Ｉｄｏｎ'ｔ．

②Does he watch TV every evening？他每晚都看电视吗？Yes，ｓｈｅｄｏｅｓ．Ｎｏ，ｓｈｅｄｏｅｓn't．
