在中考英语中有类题型叫句型转换,通常以陈述句肯定变否定、一般疑问句、特殊疑问句和选择疑问句等多种形式出现。今天小编就陈述句肯定变否定为同学们做一个详尽的讲解!
1. You had better come.
误: You didn 39; 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。
2. Both Tom and Xiao Ping went to school.
误: Both Tom and Xiao Ping didn 39; t go to school.
正: Neither Tom nor Xiao Ping went to school.
3. Tom went to school too.
误: Tom didn 39; t go to school too.
正: Tom didn 39; 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 39; t had supper already.
正: He hasn 39; 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 39; t a good rest just now.
正: He didn 39; 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 39; s do it.
误: Let 39; s don 39; t do it.
正: Don 39; t let 39; s do it. 或 Let 39; 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 39; t或在不定式前加 not。
7. He always gets there on time.
误: He doesn 39; t always get there on time.
正: He never gets there on time.
析: He doesn 39; 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. 否定 It seldom rains here.
8. Be here early tomorrow.
误: Be not here early tomorrow.
正: Don 39; 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 39; t。
9. 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。
10. I think she is there.
误: I think she isn 39; t there.
正: I don 39; 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。
