I saw he went into the room.He must be in the room, _____ ？反义疑问句

will you 祈使句的反义疑问句一般用will you
isn't it （must这里是对现在的肯定推测，所以用现在时）
B 试题分析：本题的含义是他一定在房间里，因为房间里的等是开着的，open和on都可以表示开着的，但on通常指电器开着的，而open通常指门或窗户开着，故本题选B。点评：在英文中我们应该注重部分同义形容词的区别，本题中的on表示有关电器开着的，而open表示门窗开着的，在英文的实际使用中应注意它们的区别。
mustn't he反意疑问句

★ 值得注意的是有时英语的谓语动词并不用否定式（即没加上not），
而是用上了“never, little, few, hardly, nothing, nobody”等词，这时该陈述句也属于否定句，因此，反意疑问句的后半部分应用肯定疑问式。

反意疑问句综述
反意疑问句提出情况或看法，问对方同不同意，这种问句都由两部分组成，前一部分用陈述句的形式，后一部分是一个附着在前一部分上的简短问句。
1．一般情况下，如陈述句中含有助动词、情态动词或系动词be, 则在附加疑问句中应重复此助动词、情态动词或系动词be, 问句中的主语应与前面陈述句的主语同指一个(些)人或物。如：
He has finished his homework, hasn’t he?
She can’t swim, can she?
Mary is a college student, isn’t she?
2．如陈述句部分中谓语动词仅为实义动词。则应借助于助动词do 的适当形式引导问句。附加疑问句部分的主语与陈述句的主语一致。如：
You went home yesterday, didn’t you?
He likes playing basketball, doesn’t he?
3．如陈述句部分是 I 引导的主系表结构组成，附加疑问句部分的主语仍用第一人称单数，但谓语动词应用are的某种形式，一般不用am。如：
I’m a teacher, aren’t I / ain’t I?
4．若陈述句部分为祈使句，则附加疑问句部分中用will you 或 won’t you。如：
Be quick, won’t you / will you?
Let us have a rest, will you / won’t you?
但如陈述句部分为否定祈使句，附加疑问句部分用will you。如：
Don’t smoke here, will you?
Don’t make so mush noise, will you?
如果陈述句部分为let’s 开头的祈使句，附加疑问句部分用“shall we?”。如：
Let’s stop here, shall we?
5．如陈述句部分含有hardly, seldom, never, little, few, never等否定意义的词时，附加疑问句部分要用肯定形式。如：
He hardly raised his head, did he?
She is never here on time, is she？
6．如陈述句部分的主语为nothing, nobody, none, no one 等含有否定意义的不定代词时，附加疑问句部分用肯定形式。如：
Nothing has happened, has it?
No one knows about it, does he?
7．如陈述句部分的主语为表示物的不定代词everything, something, nothing, anything等时，附加疑问句部分主语应是it。如：
Nothing has been taken away, has it?
Everything is right, isn’t it?
8．陈述句部分的主语为表示人的不定代词no one, someone, nobody, everyone, anybody, anyone等时，附加疑问句部分主语用they 或 he。如：
Everybody knows how to do it, don’t they/ doesn’t he?
Nobody was there, wasn’t he / weren’t they?
9．如陈述句部分的谓动词或表语是通过加前缀构成的否定词，附加疑问句部分用否定形式。如：
He is unfit for the job, isn’t he?
They discovered the secret, didn’t they?
It is unnecessary to write down all the words and phrases, isn’t it?
10.陈述句部分的主语是“none+of+ n.”, 附加疑问句部分的谓语在人称和数上应和这个名词保持一致。如：
None of the students went there, did they?
None of the dish smells good, does it?
11. 陈述句部分是一个复合句，附加疑问句部分的主语谓语在人称和数上一般与主句保持一致。如：
He said he would help me, didn’t he?
You promised that you would do me a favour, didn’t you?
12．在复合句中，如果主句的主语是I，谓语动词是think, believe, suppose, guess等时,附加疑问句部分的主语和谓语应和从句保持一致。当主句或从句中出现否定词时，则附加疑问句部分一律用肯定形式。如：
I don’t think you are right, are you?
I believe he will come today, won’t he?
I suppose you know him, don’t you?
13．陈述句部分的谓语动词是wish，附加疑问句部分应用“may+主语”。如：
I wish to go there tomorrow, may I?
I wish to have a word w ith you, may I?
14．陈述句部分是there be 句型时，附加疑问句部分主语用“be there”的适当形式。 如：
There are a lot of students in the hall, aren’t there?
There won’t be any trouble, will there?
There is something wrong, isn’t there?
15．陈述句部分的主语为this 或that，附加疑问句部分的主语用代词it；如果是these 或those，用they。如：
This is a desk, isn’t it?
These are books, aren’t they?
16．当动词不定式、动名词短语、从句作主语时，附加疑问句部分主语用it，谓语动词由陈述句部分决定。如：
To see is to believe, isn’t it?
What he said is true, isn’t it?
Where to hold the meeting has not been decided, has it?
Learning how to repair motors takes a long time, doesn’t it?
17．如果陈述句部分由两个或以上的并列句组成，则附加疑问句部分的主谓语应和最后一个分句保持一致。如： He studies hard and he is the best one in his class, isn’t he?
He got up late, and he didn’t arrive on time, did he?
He has been wr iting letters all afternoon, and he should be finished, shouldn’t he?
18．当陈述句部分含有情态动词must，且表示推测意义“一定”、“想必”时，附加疑问句部分不能用must，而应根据陈述句部分的不定式结构采用相应的主动词或助动词。
(1) must be, must be doing 的反意问句用be not 的简略式。如：
He must be your friend, isn’t he?
They must be huntin g in the mountains, aren’t they?
(2) must +have done (been) 时，若动作在过去发生，用didn’t / wasn’t / weren’t；若动作延续但现在或已经完成，则用haven’t/ hasn’t。如：
He must have been a schoolboy when the war broke out, wasn’t he?
He must have joined the army when he left home, didn’t he?
Charlie must have worked here for 12 years, hasn’t he?
It’s one o’clock in the afternoon. They must have had lunch, haven’t they?
(3) must+动词原型（be,have除外)，用do / does / did not 的简略式，若must 后接表示 “有”的意思的have，则用have / has / had not 或 do / did/ dose not皆可。如：
He must feel terrible, doesn’t he?
You must have a lot of jewels, haven’t / don’t you?
19．当陈述句部分的must 表示“必须”时，附加疑问句部分用mustn’t; must 表示“有 必要”时，附加疑问句部分用needn’t；mustn’t 表示“禁止”时，附加疑问句部分一般用must,有时用may。如：
You must work hard next term, mustn’t you?
I must answer the letter, mustn’t it?
You must go back right now, needn’t you?
You mustn’t walk on grass, must you?
20．当陈述句部分含有情态动词ought to 时，附加疑问句部分可以用oughtn’t ( in British English)，也可以用shouldn’t(in American English)。如：
You ought to go there, oughtn’t you / shouldn’t you?
21．当陈述句部分含有情态动词need，dare 时，如果need, dare 为情态动词，则附加疑问句部分应重复此动词；如果是实意动词时，则要借助助动词do。如：
You dare to swim in the sea, don’t you?
He needn’t say sorry to me, need he?
22．当陈述句部分的谓语动词是have 时,附加疑问句部分应视不同情况采用不同形式。
(1) have意为“有”时，附加疑问句部分采用have或do 的形式。如：
She has two children, hasn’t she?/doesn’t she?
She doesn’t have a new bike, does she?
(2) 其他情况下，则应借助于do。如：
They had a meeting here yesterd
didn't he?
she must have finished reading the novel last night,【didn't she 】?
句中有时间的标志性短语 last night，时态就只能用一般过去时，不可以用完成时。【反义疑问句肯定要根据时态，所以是didn't she 】
陈述部分有must 的疑问句，疑问部分根据实际情况而定。
A．must表示“应该”，其疑问部分用mustn't（不应该），如：You must work hard next term, mustn't you ? 下学期你应该努力学习，对吗？
B．must表示“必须”，其疑问部分用needn't（不必），如：They must finish the work today, needn’t they? 他们今天必须要完成这项工作，是吗？
C．陈述部分含情态动词mustn't，表示禁止时，疑问部分就可以用must或may，如：You mustn’t stop your car here, must you? (may we?)你不能把车停在这地方，知道吗？
D．must表示推测 ，其疑问部分必须与must 后面的主要动词相呼应。如：
①对现在动作或存在的情况的推测 ： You must know the answer to the exercise, don't you? 你一定知道这项练习的答案，是不是？ That must be your bed, isn't it? 那一定是你的床，是吗？
②对过去发生的动作或存在的情况的推测：
a 表示肯定推测
（一）句中陈述部分没有表示过去的时间状语，这时疑问部分中的动词就用现在完成时。（haven’t / hasn’t + 主语） You must have told her about it, haven’t you? 你一定把这事告诉她了，是
He must be in the room, __ISN'T HE?___
must在这里是表猜测的，解释为“肯定”==( I am sure) he is in the room , isn't he ?
is't he
