Answer 1

1.A
2.C
3.C
4.B
5.D
6.A

解：
1.dare有两种词性：1.实义动词 2.情态动词
dare后面直接加的是not，可知dare在此作情态动词
若是实义动词就应该是The little boy does not dare to go to church.

所以就跟就反义疑问句原则：前否后肯，用dare he？
其实当你判断出它是情态动词时，你就可以把它替换成比较熟悉的can或者must等之类的词来分析了

2.此句为 You think 引导的宾语从句。选C
相关语法：带有定语从句或宾语从句的主从复合句，若其陈述部分为I(We) think(believe, suppose, consider, expect) + that从句及其否定形
式时，问句部分的动词及主语与that从句内的动词和主语保持一致。
如：① I think that he has done his best, hasn’t he? ② We think that English is very useful, isn’t it? (不用don’t we?)
　　③ I don’t think that you can do it, can you? (不用do I?) ④ We don’t believe that the news is true, is it? (不用do we?)
以上题不符合，所以以常规的来答

3.同样是宾语从句，问句部分的动词及主语与主句保持一致。 Nobody引导时，反义为肯定。所以用 will they,选C
相关语法：1.带有定语从句或宾语从句的主从复合句，问句部分的动词和主语与陈述部分的主句动词和主语保持一致
2.反意疑问句的陈述部分带有little, few, never, hardly, seldom , rarely , nothing , nobody 等否定意义的词时，问句部分用肯定式。
如： ①She never tells a lie, does she?(不用doesn’t she?) ②He was seldom late, was he?(不用wasn’t he?)

4. 这里的 must have done 表示推测，且没有时间状语。所以选B

相关语法：当用must(may, might) + have + V-ed表示推测时，若句中没有带明显的过去时间的状语，问句部分动词用现在完成时形式
如：①Everyone must have known the death of the waitress, haven’t they? (不用mustn’t they/ didn’t they ?)
　　②You must have worked there, haven’t you?(不用mustn’t you?/ didn’t you?)

5. 这里的must be意为一定是，反义用be(not)+主语，为aren't you，选D

相关语法：当must be表“一定、必定”时，疑问部分助动词就用be. 如：He must be very tired after running, isn’t he ?

6.此句为Let's 引导的祈使句，问句部分均用shall we，所以选A
相关语法：
陈述部分为祈使句时，除以Let’s……引导的问句部分shall we? 如： Let’s go home together, shall we? 外，其余祈使句(无论肯、否定)，问句部分一般用will you?形式表示请求
如：①Let us stop to rest, will you? ②You feed the bird today, will you? 　
③Please open the window, will you? ④ Don’t make any noise, will you?
