初中英语中的部分否定(即不完全否定)有以下几种表示方法:
一、 all 的否定式:not all…(或:all…not)表示"并非都……"、"不是所有的都……"
eg: Not all students can study English well. (= All students
cannot study English well.) 并非每一个学生都能学好英语。
二、 both 的否定式:not…both (或:both… not) "并非两个……
都……"
eg. I don't want both the tickits to the Sound of Music.
我不是两张《音乐之声》的票都要。
Both (the) books are not mine. 两本书并不都是我的。
三、 not…and…的否定式,被否定的往往是and后面的那一部
分。
eg. She cannot sing and dance. 她会唱歌但不会跳舞。
如果将and 换成or,not 对其后面的两部分就全盘否定了。
She cannot sing or dance. 她既不会唱歌也不会跳舞。
四、 all the time 的否定式:"并非一直……"、"未必老是……"
eg. A foolish man doesn't make a mistake all the time. 笨
人未必老是犯错误。
五、 every…的否定式:"不是每……都……"
eg. Not everyone likes this book. (=Everyone doesn’t like
this book.)并非人人都喜欢这本书。
六、 always的否定式:"并非总是(并非一直)……"
eg. He is not always so sad. 他并不是一直都这样悲伤。
如要对上述的all, both, all the time ,every, always等词
作完全否定,那就分别要用与之相对应的全否定词,如no, none,
neither, no one, never, not (never)… at all 等。
eg.All of them came.--- None of them came.
Both are good.---Neither is good.
He was here all the time. --- He was never here
Everybody likes it. ---Nobody likes it.
He is always late. --- He is never late.
