我不仅要答案，要讲解，要详细。否则不给分啦。啦啦啦，麻烦咯。

Answer 1

第一道题目是考察形式主语的主语从句，
it happen/ seem/ appear/ turn out / prove that, ,,, 看到这种句型就用it .
它本来的结构是 that he had no money with him happen,,,但是谓语happen前面全部都是主语，所以就放了没有任何意思的it, 既然it 只是摆摆样子，我们把它叫做形式主语。
2. 考察反义疑问句，有几个反义疑问句要特别注意， had better do, would rather do , would like to do 注意他们的反义疑问句句就是看 had, 和 would ,,另外，have to do , 这个要看have to 动词的形式。 比如， he had to clean the room, didn't he? he has to work now , doesn't he?
3. must have done 的反义疑问句要注意，无时间状语，用 haven't sb, 这个题目选A。
如果是有时间状语，如， you must have finished your work yesterday, 那么就是 didn't you?
另外，，sb must be a doctor, 后面用 isn't sb?
第二第三题 是反义疑问句的难点，复习要格外小心，在一些非正式考试中常碰到，但是最近几年的中考高考不怎么考，因为这个语法是死记硬背，不符合新时代根据语境学习语法的原则。

Answer 2

1、B。表示恰好，适逢。
2、D。反义疑问中用would rather + v.做陈述部分时，用wouldn't +主语提问。
3、C。反义疑问中当must+have done表示对过去的情况进行推测（一般句中有明确的过去时间状语），问句要根据陈述部分谓语的情况用“didn't+主语”或“wasn't/weren't+主语”；如果强调动作的完成（一般没有明确的过去时间状语），问句要用“haven't/hasn't+主语”。

追问

那么3应该选A才对啊。

追答

对哦，看错了，不好意思。

Answer 3

1A 这句话是句型问题 肯定不能是that that 是要用it 这种是没有什么理由的 就是句型 所以还是要多读读书有语感比什么都重要 我刚高一 经验之谈
2D陈述部分有would rather +v.，疑问部分多用 wouldn't +主语。
例如He would rather read it ten times than recite it, wouldn't he?

3A 这句话是表推测的 must是情态动词 所以关键看have 因为意思是你完成了作业 所以反义疑问词是haven't

Answer 4

B 指代that后面那个句子
B前面肯定后面否定，排除A和C，又因为句子的动词还是do，所以是B
C 做这种句子的时候，要先把现在完成式去掉，然后改成一般语态，

Answer 5

1、B这个靠的是语感选的，说不出具体原因
2、D前肯后否，would保留
3、C去掉过去完成时和情态动词
