19) 否定前缀不能视为否定词,其反意疑问句仍用否定形式。
It is impossible, isn't it?

有些动词如:cost hurt hit put 等,它们的过去时与原型相同,在肯定句中一定要先弄清楚它们是什么时态.

  • 英语18种特殊的反意疑问句:
    1.祈使句。祈使句后一般加上will you或won't you构成反意疑问句,用will you 多表
    示“请求”,用won't you 多表示提醒对方注意。例如:    
    Look at the blackboard, will you/ won't you?看黑板,好吗?   
    Let 引导的祈使句有两种情况:   
    1) Let's...后的反意疑问句用shall we或shan't we。例如:   
    Let's go home, shall we/ shan't we? 回家吧,好吗?    
    还可以用may I来表示征求对方的同意或许可。   
    2) Let us/me...后的反意疑问句用will you或won't you。例如:    
    Let me have a try, will you/won't you? 让我试一试,行吗?   
    2. 感叹句。感叹句后加反意疑问句时,其反意疑问句需用be的一般现在时态的否定形式。 例如:   
    What fine weather, isn't it? 多好的天气啊,是吧?    
    3. 当陈述部分谓语动词是need, dare, used to,且这些词被用作实义动词时,其反意疑问 句需用do的适当形式。例如:   
    He needs help, doesn't he? 他需要帮助,是吗?    
    4. 陈述部分主、谓语是I am...时,反意疑问句用aren't I 或am't I ,而不是am not I (可 用a m I not)。例如:

    6. 陈述部分的主语是 everybody, everyone, anybody, anyone, somebody, someone, nobody, no one, none, neither 时, 其反意疑问句的主语需用复数代词they。 例如:   
    Everyone is here, aren't they? 大家都到了,是吗?   
    No one knows about it, do they? 没有人知道这件事,对吗?   
    7. 陈述部分的主语是指示代词this或that时,反意疑问句的主语用it,当陈述部分的主语是指示代词these或those时,其反意疑问句的主语用they。 例如:   
    This is a plane, isn't it? 这是一架飞机,是吗?   
    These are grapes,aren't they? 这些是葡萄,是吗?   
    8. 陈述部分的主语是不定代词one时,反意疑问句的主语可以用one,也可用you(美式英语用he)。例如:   
    One should be ready to help others, shouldn't one? 每个人都应该乐于助人,是吧?   
    9. 当陈述部分含有以下这些含有否定意义的词时:few, little, seldom,hardly, never, not,  no, no one, nobody, nothing, none, neither等,其反意疑问句需用肯定结构。 例如:    
    He is never late for school, is he? 他上学从不迟到,是吗?   
    10. 当陈述部分所含的否定词是通过加前缀或后缀构成的,其后的反意疑问句依然用否定结构。例如:   
       It is unfair, isn't it? 这不公平,是吧?   
    11.含有否定含义的词在陈述部分作动词的宾语时,其反意疑问句用肯定结构,也可以用否定结构。例如:   
    You got nothing from him, did you? 你从他那儿什么也没得到,是吗?   
    12. 当陈述部分主语是从句、不定式(短语)、动词-ing形式时,反意疑问句的主语应该用it。  例如:   
    What you need is more important, isn't it?你需要的东西更重要,是吧?   
    13. 当陈述部分含I think (believe, suppose...)that... 结构时,其反意疑问句须与从句的主、谓语保持一致,注意主句的主语必须是第一人称。例如:   
    I don't think he will come, will he? 我认为他不会来,对吗?   
    14.have(has)不是表示“有”的意思,并在句中做谓语时,其反意疑问句的助动词要用do, does, did。例如:   
    They had a meeting just now,didn't they? 他们刚才开了个会,是吗?   
    15. 陈述部分有have to 时,其反意疑问句要用助动词的否定形式。例如:   
    You have to water the vegetables every day, don't you?你每天都要浇菜,对吧?

    We had better go to school at once, hadn't we? 我们现在最好马上去上学,好吗?
    18. 当陈述部分含有情态动词must时,我们便要分析一下must的含义。如果must 作“一定;要;必须”讲,反意疑问句须用mustn't或needn't;
    而当must作推测意义“一定 是;必定”讲时,反意疑问句则需根据must后的动词原形选用相应的形式。例如:    
    He must work hard at physics, mustn't he? 他必须努力学物理,是吧?   
    Tom must be at home,isn't he? 汤姆一定在家,是吧?
