Don't run and jump in the classroom.Don't run or jump in the classroom.这两句一样吗?
Don't run and jump in the classroom.Don't run or jump in the classroom.这两句一样吗?
不一样 ,or用于否定句中连结并列成分,表示“和,与”之意。例如:
There isn`t any air or water on the moon.月球上既没有空气也没有水。
The baby is too young. He can`t speak or walk.那婴儿太小,他不会说话,也不会走路。
He hasn`t got any brothers or sisters.他没有兄弟和姐妹。
and 常用在肯定句中列举并列成分,但也可用在否定句中列举并列成分,条件是双重否定句或 and 前后都有否定词。例如:
No fly and no mosquito has been found in that modern hotel.
Man can't live without air and water.
从上面的用法可以看出Don't run or jump in the classroom.的意思是不要在教室里跑也不要在教室里跳,全部否定。Don't run and jump in the classroom。不要在教室里跑或者不要在教室里跳。
一般否定句用or来连接
不一样not A and B 部分否定不要在教室里面又是跑又是跳的.【含意:你单跑跑(或是跳跳)我都忍了】not A or B 全部否定在教室里面你们既不能跑也不可跳再如:I don't know English and French.我不是英语法语都懂的...
