前面是否定后面就是肯定,反之亦然~
I don't think he will come tonight,_____ _____?
She doesn't think he will come tonight,_____ _____?
don't think 和doesn't think 都是否定,所以后面用肯定,当然再判断主要强调的部分,第一个强调是he will come tonight,第2个是she doesn't所以要用肯定(前面分析了),will he,dose she?
不过,假如前面是双重否定,那即是肯定了(负负得正),这时候后面要用否定,例如:I don't think he won't come tonight,won't he?
总之,前面肯定后面否定,前面否定后面肯定,
