否定关系题主要考察英语中否定的表达，因此掌握一些表示否定意义的单词、短词，是做好这部分听力题的关键：
(1)表示否定的词语
hardly, barely, seldom, rarely, scarcely, little, few; nobody, nothing, neither, not, no, nor, never, none; deny, fail, miss, doubt, beyond, without, no one, nowhere, past, ignore, overlook, above, off, miss, dislike, eliminate, reject, deny, fail, stop, lease, decline, grudge, refuse
(2)表示否定的短语
at a loss, out of, instead of, short of, independent of, devoid of, ignorant of, innocent of, far from, free from, rather than, not everywhere, all... not, both... not, every...not, no...no (not), not...without, no (no not, nothing, never)... but, too...to, can't but, can't help but, not (never, no) ...unless, not...until, neither... nor, anything but, not better than
(3)表示否定的句型
She should know better than to trust such a man.
=She shouldn't trust such a man.
Catch me doing that.
=I shall not do that.
If ever I heard the like.
=I never heard the like.
That science is all Greek to me, and I cannot follow it at all.
=I know nothing about that science, I can't understand it.
I'll eat my hat if I do.
=I shall not do that.
God knows!
=It is not something that ordinary people can know.
值得注意的是，有时英语中否定的意思不是直接表达出来的，而是要听完整个对话，结合上下文甚至语音语调进行判断，这是否定关系题中比较难的题目。
例如：① How could anyone do such a thing? ↓
　　 =It is unlikely that anyone could do such a thing.
② Have I enough time? ↓ =I don't have enough time.
