看句子前面,如果有动词后面就是用前面那个动词,比如你举得例子,前面动词是was,后面就是用was,如果是其他动词,就用那个动词,如果没有动词,就是用助动词了,句子这样翻译：我认为他是不快乐的.是个否定句,后面问的就是肯定was.

举例She likes shopping,doesn't she?
She has gone to Bijing,hasn't she?
It is a book ,isn't it?
She can speak three languages.can't she?
答疑：该句子是否定的转移，实际译为He wasn't happy,wsa he?

（1）当陈述部分有never，seldom, hardly，few，little，barely, scarcely, nothing 等否定意义的词汇时，后面的反意疑问句则为肯定形式： 　　There are few apples in the basket, are there? 　　He can hardly swim, can he? 　　They seldom come late, do ...

（1）当陈述部分有never，seldom, hardly，few，little，barely, scarcely, nothing 等否定意义的词汇时，后面的反意疑问句则为肯定形式： 　　There are few apples in the basket, are there? 　　He can hardly swim, can he? 　　They seldom come late, do they? 　　（2）当陈述部分含有否定意思的词是unhappy,dislike,unfriendly等含有否定词缀的派生词，也就是有un-前缀、-less后缀等含有词缀而意思否定的词，当做肯定句处理，疑问部分要用否定形式。如： 　　He looks unhappy,doesn't he?他看上去不高兴，不是吗？ 　　The girl dislikes history,doesn't she?这女孩不喜欢历史，不是吗？有less,fewer等词视为肯定词，疑问部分用否定形式。如：　There will be less pollution, won't there?
表示主语主观意愿的词
　　含有think, believe, suppose, imagine, expect等动词后接宾语从句构成的主从复合句在构成反意疑问句时，视情况不同有两种不同的构成方式。 　　(1.)当主句的主语为第一人称时，其后的简短问句应与从句相一致。例如： 　　I expect our English teacher will be back this weekend, won't she/he? 　　We suppose you have finished the project, haven't you? 　　值得注意的是，当这些动词后接的宾语从句的否定转移到主句时，其仍属否定句，故其后的简短问句应用肯定式，而非否定式。例如： 　　I don't believe that he can translate this book, can he? 　　We don't imagine the twins have arrived, have they? 　　此类句子的回答同"前否后肯"型反意疑问句一样，如上述后一个句子，若双胞胎已经到了，则回答为"Yes, they have."；若尚未到达，使用"No, they haven't."。 　　(2).当主句的主语为第二、三人称时，其后的简短问句则应与主句相一致（此时，否定只看主句，与从句无关...）。例如： 　　Your sister supposes she needs no help, doesn't she? 　　You thought they could have completed the project, didn't you? 　　They don't believe she's an engineer, do they? 　　She doesn't expect that we are coming so soon, does she? 　　(3)但如果主句的时态是过去时等等，疑问句应和主句的人称时态保持一致。
had better或have
　　陈述部分有had better,或其中的have表示完成时态时，疑问句应用hadn’t等开头： 　　You’d better get up early, hadn’t you? 　　其他情况句中有have时疑问句应用don't等开头 　　如have表示“有”的时候，有两种形式：（have 表示有 可用do或 have来改写） 　　-He has two sisters,doesn't he? =He has two sisters,hasn't he? 　　-He doesn't have any sisters,does he?
祈使句
　　当陈述部分是祈使句时，疑问句要根据语气来表达，分三种情况： 　　1）一般情况下用will you 或 won't you。 　　e.g. Give me a hand,will you? 　　Leave all the things as they are,won't you? 　　2)以Let's开头的祈使句，前肯后可肯可否，前否后只可，疑问句用shall we;以Let us或Let me开头的祈使句，问句用will you。(let us开头，应用shall we) 　　e.g. Let's go out for a walk, shall we? 　　Let us go out for a walk, will you? 　　Let me help you,will you? 　　3)当陈述句是否定的祈使句时，问句可用will you 或 can you 。 　　e.g. Don't make much noise,will/can you?
There be句型
　　There be 句型中，反义疑问部分必须为be 动词 + there 　　　There are some apples in the basket, aren't there? 　　There isn't any milk left, is there?
must
　　.当陈述部分有情态动词must，问句有4种情况： 　　（1）mustn't表示“禁止，不可，不必”时，附加问句通常要用must. 　　You mustn't stop your car here,must you? 　　你不能把车停在这地方，知道吗？ 　　（2）must表示“有必要”时，附加问句通常要用needn't. 　　They must finish the work today,needn't they? 　　他们今天要完成这项工作，是吗？ 　　（3）当must用来表示对现在的情况进行推测时，问句通常要根据must后面的动词采用相应的形式。 　　He must be good at English,isn't he? 　　他英语一定学得很好，是吗？ 　　（4）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”。 　　She must have read the novel last week,didn't she? 　　她上星期一定读了这本小说，是吗？ 　　You must have told her about it,haven't you? 　　你一定把这事告诉她了，是吗？
非反义疑问句
　　非反义疑问句的陈述部分和疑问部分要么同是可定的，要么同是否定的。这类反义疑问句有时带有感情色彩，表示惊奇，愤怒，讽刺，不服气等。例如：You call this a day's work，do you？你说这就叫一天的活儿，是吗？
