None is so blind as those who wont see. 没有比视而不见的人更瞎眼的了。13not.for nothing中,not用来否定for nothing,从而加强了谓语的肯定意义。例如: He didnt study law for nothing. 他学法律并没有白费。Believe me, he did not fly into such a rage for nothing. 请相信我,他勃然大怒是有原因的。 14否定的感叹句、疑问句常表示肯定意义。例如: Isnt this film interesting? 这部电影难道没趣吗?Who doesnt enjoy reading The Dream of the Red Mansion? 谁不喜欢看红楼梦呢?(人人都喜欢看红楼梦。) 15. 以Why dont you.和Why not . 开头的疑问句往往表示邀请、建议、指导等,具有肯定意义。例如:Why dont you introduce her to your parents? 你为什么不把她介绍给你父母呢?Why not come and see me tomorrow? 明天来看我怎么样? 16. nothing （或 no + 名词） but 只有；仅仅；Nothing but=only ，表示肯定意义，后接名词、代词、不定式等。例如：No one but him in our class can swim across the river. 在我们班上，只有他能游过这条河。 She could do nothing but wait here. 她只好在这时等，别无他法。 其它的否定词but1、not(no)butThere is no man but has his faults. 人皆有过。No one believes but she will succeed. 人们相信他会成功。There is no one but knows him. 人人都认识他。 17. 祈使疑问句;否定感叹疑问句表示的肯定表示肯定意义。例如：Isnt the film wonderful？ 多么好的一部影片啊！ Wont you have some beer? 请喝点啤酒吧！Wont you sit down! 请坐呀! Isnt that beautiful! 多么美丽呀!Isnt she a sweet girl! 她多么可爱啊! 18. hardly / scarcely when 一（刚）就；在这个句型中， when 是并列连词，其前面的句子要用过去完成时，其后的句子用一般过去时。例如：He had hardly/scarcely arrived when it began to rain. 他一到天就开始下雨了。Hardly/Scarcely had he arrived when it began to rain. 他一到天就开始下雨了。 We had scarcely reached the school before/when the bell rang. 我们刚到学校铃声就响了。 He had scarcely escaped when he was recaptured.他刚逃掉就被逮住了。 He had hardly arrived when she started complaining.他刚一到, 她就开始抱怨起来。 19.no sooner than 一（刚）就；在这个结构中， no sooner 位于主句中，主句用过去完成时， than 引导状语从句，从句用一般过去时。例如：No sooner had they got to the theatre than the concert began. 他们刚跨进剧院，音乐会就开始了。 20. can + not + be + 形容词 + enough/can not + 动词原形 + too much （ highly ）越越好；无论怎样也不过分；在这个句型中， not 可用 never 来替代。例如：He is a hero. We can not praise him too much （highly）。他是英雄，我们无论怎样赞扬他也不过分。 21. 否定词比较级( 相当于最高级), 常见的句型是：have never + 过去分词 + 比较级最；再没有比更；该句型从反面表示“最”的概念。例如：We have never seen a more interesting film than this one = This is the most interesting film that I have ever seen. 这部电影是我们看过的最有趣的影片。 I couldnt agree more. 我非常同意。Nothing is more valuable than health. 健康是最宝贵的。 22. cant （help） but 只好；不得不；必然；在这个结构中， help 可省略， but 后面接不带 to 的不定式。例如：He cant （help） but admit that he was wrong. 他只好承认自己是错了。23. cant help doing sth. 情不自禁地做某事 Hearing the joke， we couldnt help laughing. 听了这个笑话，我情不自禁地笑了起来。24. not + 含否定意义的词缀的词。例如： It is not uncommon for a great scholar to be ignorant in everyday affairs. 一个伟大的学者，对日常事务无知，这种情况并不罕见。25.有些带否定词的短语,在使用时并不构成否定意义,即表示肯定意义。例如: He would go as soon as not. 他非常乐意去。As often as not the buses are late on foggy days. 遇多雾天气时,公共汽车经常晚点。 26. not a little意为 “很,很多” He is n
