Nobody knows about it,______?反意疑问句,后面应该填什么

2.动词作谓语的时候,分为现在时和过去时,其实都一样的,就是用do ,does ,did 的问题,就看主语是单数还是复数,单数就用does,复数就用do,动作发生在过去就用did,然后就是看前面的主句是否定还是肯定的问题了,和我第一点说的意思一样.
3,就是特殊的句子了,
祈使句,用will you
let’s .,shall we?
let us.,will you?
还有一些词表示否定意义的,如hardlly ,marely ,sincerely,当他们放在句子里时,后面的反义疑问用肯定的

填does he
1. 当陈述部分有no,nothing,nobody,never,few, seldom, hardly, arely, little等否定含义的词，疑问部分应为肯定含义
2. 当陈述部分的主语是everyone，everybody，someone，somebody，anyone，nobody等，附加疑问句中主语一般用he（书面语）/they（口头语）。

然后时态要保持一致，所以助动词因该是does

does he?

1.is he.2.are you.3.does he.——一二题解法基本相同, 因为反疑的模式是前句肯定则后句否,前句否定则后句肯定,因为1.2句有don't,doesn't所以后句肯定,又如果句中有think,suggest等词时,反疑的主语为主句(如1中的I don't think)的从句(he is),即后句的主语用he.疑问词用is,第3句有否定词little,后句肯定疑问代词用does...
