句型转换错误分析复习_九年级英语教案

    1. i think she is there.
    误:i think she isn't there.
    正:i don't think she is there.
    析: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。
