众所周知，英语里含有not或no等词语的句子，其意义为否定，但有时句子形式上看来是否定，意义上却是肯定的。现作一简述。
一、否定的感叹疑问句。这种句子形式上是否定句而实际上是感叹句。表示说话人强烈地想引起听话人对所说事情的同感，表达赞美或惊叹等情绪。这种疑问句句末用感叹号，是一种语气很强的肯定句，读时要用强而有力的降调。
Isn't the cloth magnificent!（相当于：How magnificent the cloth is!）这布料多华丽啊！
Aren't the babies lovely!（相当于：How lovely the babies are!）这些婴儿多可爱呀！
二、否定修辞性疑问句。这种疑问句表示说话人对自己的观点深信不疑，表达惊讶、赞扬、批评、责备等情感，并不期望对方回答，只是作为一种修辞手段来加强句子的语气；形式上是否定疑问句，实际上是一个强调的肯定陈述句。
Didn't I tell you they had gone?（相当于：I did tell you they had gone.）我不是告诉过你他们已经走了吗？
Can't you be more careful?（相当于：You should have been more careful.）你就不能再仔细一点吗？
It's a lovely day,isn't it?（相当于：It's a lovely day indeed.）今天天气真好。
Who does not know that?（相当于：Everybody knows that.）那件事谁不知道啊？
三、否定祈使句。这种祈使句表示试探性的建议、看法，或有礼貌的邀请或征询别人的看法；所表达的意义是肯定的，但语气比较客气、委婉。
Can't you borrow some jewelry from a friend,Mathilde?（相当于：You can borrow some jewelry from a friend.）你不能向你的朋友借些首饰吗，玛蒂尔德？
Don't you think we should stop here?（相当于：We should stop here.）是不是到此为止？
Have a cup of tea,won't you?（相当于：Please have a cup of tea.）请喝茶。
四、双重否定句。在这个句型中，两个否定词同时使用，否定之否定，达到“负负得正”之效果。这是一种表达强烈思想情感的肯定句，能起到一般肯定句所不具备的表达功能。
There is no success without hardships.没有磨难，就没有胜利。（没经历风雨，怎么见彩虹。）
One is never too old to learn.活到老，学到老。
Nothing is impossible to a willing mind.世上无难事，只怕有心人。
五、否定的虚拟语气。虚拟语气表示愿望或假设与事实相反，因此否定的虚拟语气句子所表达的意义是肯定的。
If it were not hot today,I would go out.（相当于：It is hot today and I don't go out.）如果今天不这么热，我就出去了。
If you hadn't watched that late movie last night.you wouldn't be so sleepy now.（相当于：You watched that late movie last night,so you are so sleepy now.）昨夜你不去看那场放映得很晚的电影，你现在就不会这么疲倦。
六、含有not a little（非常）、not a few（许多）、no more than（只有）、not more than（至多）、not the less（还是、仍旧）、no/none other than（正是）、no less than（不亚于、简直）、not half（非常、极度地）、second to none（独一无二）等的句子，是语气很强的肯定旬。
He was not a little surprised.他非常吃惊。
I have not a few books.我有相当多的书。
He is no more than ten year sold。他只有十岁。
The news was not the less true in the main.这消息大体上还是真的。

They didn't half support my proposal.他们十分支持我的建议。
In point of skength,he is second to none.论力气，他是独一无二的。
七、否定词+be+so/as…as…（或more…than…）。这个句型是用来把同一类的一个人或物与其他一切人或物相比较，从反面来表示最高级的概念，意思是“没有比……更……的了”，是一种强烈的肯定句。
No book is so interesting as this one=No book is more interesting than this one.（相当于：This book is the most interesting book of all.）没有任何一本书比这本书更有意思了。
Nothing is more precious than time.再没有什么比时间更宝贵的了。
还可以用“否定词+表示比较的词语”表示：
He had never spent a more worrying day.（相当于：This was the most worrying day he had ever spent.）他从来没有经历过比这更令人焦虑的一天。
How beautiful she sings! I have never heard a better voice.她唱得多么动听啊！这是我听到过的最美的歌喉。

4.cannot+动词原形+too(over,enough)，意为“无论……也不过分”，“越……越好”。not可用never,hardly,scarcely等替换。

Their answer could not be more satisfactory.他们的回答非常令人满意。
