疑問句是用來提出問題的句子，疑問句共有4種：一般疑問句，特殊疑問句，選擇疑問句以及反意疑問句。上次我們講解了一般疑問句和特殊疑問句，今天我們來看看選擇疑問句以和反意疑問句。
一.選擇疑問句
選擇疑問句指問句中提出兩種(或兩種以上)可能，要求對方從中選擇。說話時or以前的部分用升調，or以後的`部分用降調。選擇疑問句有兩種句型，其作用相同。
a.用or連線兩個一般疑問句，後一個問句常省略掉與前一個問句相同的成分。
一般疑問句 + or + 一般疑問句(省略式)。
b.用特殊疑問句將問題提出，再用or將兩種供選擇的答案連線。
特殊疑問句 + 答案A + or + 答案B。
例如： you go to school by bus or by bike?
你乘公共汽車還是騎自行車上學?
How do you go to school，by bus or by bike?
你怎麼上學，乘公共汽車還是騎自行車?
you like the Chinese film or the foreign film?
你喜歡這部中國電影還是這部外國電影?
Which film do you like，the Chinese film or the foreign film?
你喜歡哪一部電影，這部中國電影還是這部外國電影?
二. 反意疑問句：
反意疑問句是指問者首先提出陳述句，然後附上簡短問句，對所陳述的事實提出相反的疑問。陳述部分總是用降調，疑問部分如用升調，是要求對方回答;如用降調，則側重表達一種語氣上的強調，表示說話人較為確信或肯定。
例如：You are very cold，aren't you?
你非常冷，是不是?
She has an elder brother，hasn't she?
她有個哥哥，是不是?
He has never been to Shanghai，has he?
他從來沒去過上海，是嗎?
回答反意疑問句，應遵守一個原則，即無論陳述部分和疑問部分是肯定還是否定形式，肯定回答就用Yes;否定回答就用No，不應受漢語的干擾。
---You aren't a Young Pioneer，are you? 你不是少先隊員，是嗎?
---Yes，I am. 不，我是。
---No，I am not. 對，我不是。
