1，反意疑問句前后兩部分謂語應(yīng)是，"肯定陳述+否定疑問"或"否定陳述+肯定疑問"。遵循前肯后否，前否后肯的原則。
2，簡略問句如果是否定式，not應(yīng)與be，do，will等系動詞、助動詞、情態(tài)動詞縮寫。
3，簡略問句的主語不用名詞，應(yīng)用人稱代詞。
4，當說話者的目的不在疑問，而是為了加強語氣時，用降調(diào)。
5，當說話者的目的在疑問，則用升調(diào)。
注意事項
附加疑問句（Tag questions）
附加疑問句的概念
附加疑問句就是對陳述句所敘述的事情提出相反疑問的問句，主要表示以禮貌或委婉的語氣提出要求、詢問或確認信息等。讀時前半部分用降調(diào)，后半部分既可以用升調(diào)也可以用降調(diào)。通常情況下，用升調(diào)時，多表示疑問或請求;用降調(diào)時，多表示求證或希望對方同意。
附加疑問句基本構(gòu)成形式
附加疑問句由兩部分構(gòu)成:前一部分是一個陳述句，后一部分是一個簡短的疑問句。兩部分的人稱和時態(tài)應(yīng)保持一致。陳述部分為肯定句時，附加疑問句用否定形式，反之用肯定式。
二、附加疑問句的用法
（一）主語問題
先看例句
1.This isn't your first time here，is it
2.Lang Ping sets a good example for us，doesn't she
3.Everything is ready，isn't it
4.There was nothing in the room，was there
5.I suppose that he will come，won't he
分 析1.主語為指示代詞時，疑問句的主語用it 或they等代詞。2.主語為名詞時，疑問句的主語用其相應(yīng)的代詞。3.主語為不定代詞時，指人，疑問句用he(she)或they;指物，疑問代詞用it。4.There be句型為特殊句型，附加疑問句的主語用there。5.在suppose guess think等后的賓語從句中，附加疑問句的主語與賓語從句保持一致。
歸 納
附加疑問句中主語的選擇是關(guān)鍵，要掌握分辨主句中的主語，并了解其代詞的表現(xiàn)形式。

(二)陳述部分含有動詞have/has/had的附加疑問句
先看例句
1.You have lost some weight，haven't you
2.All that fat has become muscle now，hasn't it
3.He had already left when you got there，hadn't he
4.He has a lot of friends here，hasn't/doesn't he
5.He had a good time at the party，didn't he
分 析
1.句1、2、3中have/has/had為助動詞，幫助構(gòu)成完成時，附加疑問句中使用助動詞+主語。
2.當have/has/had為實意動詞“有”時，附加疑問句可用have/has/had或助動詞do/does/did。
3.當have/has/had表示“吃、玩”等意義時，附加疑問句要借助于助動詞do/does/did。
歸納：have/has/had具有助動詞和實意動詞兩種功能，因此在使用中一定要分清楚。
