  中考句型转换错误分析 肯定句变否定句

  1. I think she is there.

  误:I think she isn’t there.

  正:I don’t think she is there.

  析:英语中think, believe, expect, suppose等表示信念和揣测的动词,后接that从句时,习惯上将从句中的否定形式转移到主句上,即否定主句谓语,不否定从句谓语。

  2. He can sing this song and that one.

  误:He cannot sing this song and that one.

  正;He cannot sing this song or that one.

  析:肯定句中的连词and在否定句中一般要改为or。

  3. Tom went to school too.

  误:Tom didn’t go to school too.

  正:Tom didn’t go to school either.

  析:too和also用于肯定句中时,否定句中用either替换。

  4. He has had supper already.

  误:He hasn’t had supper already.

  正:He hasn’t had supper yet.

  析:随着对谓语动词的否定,某些副词也要作相应的变动。

  5. He had a good rest just now.

  误:He hadn’t a good rest just now.

  正:He didn’t have a good rest just now.

  析:have在表示开会、吃饭、休息、进行体育锻炼等词组中是行为动词,否定句用助动词来完成。

  6. Let’s do it.

  误:Let’s don’t do it.

  正:Don’t let’s do it.或Let’s not do it.

  析:let后接的是不带to的不定式,变为否定式,直接在句首前加Don’t或在不定式前加not。

  7. He always gets there on time.

  误:He doesn’t always get there on time.

  正:He never gets there on time.

  析:He doesn’t always get there on time意为“他并非老是准时到那儿”,是部分否定,习惯上把句中的副词改为相应的表示否定的副词即可。如:

  It often rains here. It seldom rains here.

  8. Be here early tomorrow.

  误:Be not here early tomorrow.

  正:Don’t be here early tomorrow.

  析:祈使句的否定,一般在谓语动词前加do not的缩写don’t。

  9. You had better come.

  误:You didn’t have better come.

  正:You had better not come.

  析:had better相当于一情态动词,不可分割,因此not应放在其后。would rather也是如此。

  10. Both Tom and Xiao Ping went to school.

  误:Both Tom and Xiao Ping didn’t go to school.

  正:Neither Tom nor Xiao Ping went to school.

  析:一个句子中如果有不定代词both,all, every改为否定式时,要把这些不定代词改为相应的表示否定的代词。
