看句子里有沒有be動詞:如果有,將be動詞提前到句首.
例:He is a clever boy.
Is he a clever boy?
沒有be動詞,看句子的主人是在哪個房間?如果在happy house,句首+Do.如果在sad house,句首+Does.加過Does以后,后面的動詞變成原型.
例:1.They study English in the classroom.
Do they study English in the classroom?
2.He jumps rope in the park.
Does he jump rope in the park?
當(dāng)句子里有關(guān)于"我,我們"的都要相應(yīng)的變成"你,你們”的.
例:I am a teacher.
Are you a teacher?
We are happy?
Are you happy?
This is my book.
Is this your book?
These are our books.
Are these your books?
當(dāng)句子里有some/many…要變成any.
例:There are some cats on the table.
Are there any cats on the table?
I have many shirts.
Do you have any shirts?

陳述句后面加一個簡短問句可將陳述句變成反意疑問句,用以對所陳述的事情取得肯定或否定的回應(yīng),或
是使表達更加禮貌.反意疑問句很少用在正式的書面英語中.
例如：1） He’s very friendly,isn’t he?他很友好,不是嗎?
2） You haven’t seen it before,have you?你以前沒有見過,對嗎?
2) You form a question tag by using an auxiliary,a modal,or a form of the main verb “be”,followed by a pronoun,the pronoun refers to the subject of the statement.
簡短問句由一個動詞和一個代詞構(gòu)成,動詞主要由助詞動詞,情態(tài)動詞和系動詞“be”構(gòu)成,代詞指代主語.
例如：1） David’s school is quite nice,isn’t it?大衛(wèi)的學(xué)校還不錯,不是嗎?
3) You can use a negative statement and a positive question tag to ask people for things,or to ask for his information.
由否定陳述句加肯定簡短問句構(gòu)成的反意疑問句可用以提出請求,要求幫助或?qū)で笮畔?
例如：1） You wouldn’t sell it to me,would you?你不會賣給我,是嗎?
2） You won’t tell anyone else this,will you?你不會告訴別人,對嗎?
4) When you want to show your reaction to what someone has just said,for example by expressing interest,surprise,doubt,or anger,you use a positive statement with a positive question tag.
由肯定陳述句加肯定疑問短句構(gòu)成的反意疑問句可用以表達對某人所述事情的回應(yīng),例如表達興趣,懷疑或 者憤怒.
例如：1） You’ve been to North America before,have you?你以前去過北美,是吧?
5) When you use an imperative,you can be more polite by adding one of the following question tags.
祈使句后面跟簡短問句構(gòu)成的反意疑問句更加禮貌.
(will you won’t you would you)
例如：1） Look at that,would you?看看那個,可以嗎?
6) “Will you” and “won’t you” can also be used to emphasize anger or impatience.“Can’t you” is also used in this way.
“will you”,“won’t you” “can’t you”也可用以表示憤怒或不耐煩.
例如：1） Oh,hurry up,will you?你快點,行嗎?
2) For goodness sake be quiet,can’t you?你能不能安靜點?
