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:

What you need is more important, isn't it?你需要的东西更重要,是吧?

I don't think he will come, will he? 我认为他不会来,对吗?

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?
