3、now.It cant bu sunny all the time.4. 表示说话人的猜测、怀疑、不肯定等，主要用于否定句、疑问句、感叹句中，带哟感情色彩。How can yo be so rude!Can he be back?5. could 可以作为 can 的过去式，也可以在提出请求时表示委婉。He could save the little boy.Could you help me?三、may, might1. 表示“许可、准许” ，此时与 can 同义，可以互换使用You may/can go to the cinema this evening.注意：表许可时其答语可以用“Ye
4、s,you may.”但是由于用 may 做肯定回答语气显得生硬、严肃，因此一般用 Yes, please. /Certainly. / Of course.这些回答显得热情、客气。拒绝对方时，其答语可以用 No, you mustnt. / No, you cant. / Sorry, you cant. / No, please dont 等-May I come in? -Yes, please-May I use your ruler? -Certainly.

7、需要时，常用_）否定式 mustnt 表示“一定不要，禁止”You must see the doctor.Must you go soon?对于 must 开头的一般疑问句，如果要做否定回答，可以用 neednt, dont have to，不能用 mustnt-Must I come over tonight? -No, you neednt2. 表示推测，意为“准是，一定是” ，但是通常只用于肯定句，在否定句、疑问句中通常用 cantIt must be true.Can it be true?

20、all D.May选 A,这种句型不太理解5.Why_it get colder when we go up a mountain?We are getting nearer to the sun!A.ought to B.would C.should D.must选 C 为什么不选 A1,can may 表示许可，（ could 是 can 表示“能够，有能力做某事”时候的委婉语），所以 could 不可以，同时 might 既是 may 的过去时，也是 may 的委婉语，用 might 回答别人，在这里不礼貌2.这题缺少上下文，所以答案不是唯一的，看个人理解，出题人出的不够严密呀3.不是虚拟语气，虚拟语气主要 2 种用法（1，表示与现实不符合的假设； 2，在建议，请求等词之后的从句里使用）4 should 可以表示“ 非常不可能的可能性 ”，并且用这个意思的时候一般倒装：Should anyone phone (ie If anyone phones), please tell them Im busy. 有人打电话来, 就说我很忙. 当然打电话 110 不是什么好事，说的可能性小点比较符合文法5 这里 should 表示“ 竟然” 如果是 ought to 那就是理所当然拉，不需要问句形式了。
