注意事项
附加疑问句（Tag questions）
附加疑问句的概念
附加疑问句就是对陈述句所叙述的事情提出相反疑问的问句，主要表示以礼貌或委婉的语气提出要求、询问或确认信息等。读时前半部分用降调，后半部分既可以用升调也可以用降调。通常情况下，用升调时，多表示疑问或请求;用降调时，多表示求证或希望对方同意。
附加疑问句基本构成形式
附加疑问句由两部分构成:前一部分是一个陈述句，后一部分是一个简短的疑问句。两部分的人称和时态应保持一致。陈述部分为肯定句时，附加疑问句用否定形式，反之用肯定式。
二、附加疑问句的用法
（一）主语问题
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.主语为指示代词时，疑问句的主语用it 或they等代词。2.主语为名词时，疑问句的主语用其相应的代词。3.主语为不定代词时，指人，疑问句用he(she)或they;指物，疑问代词用it。4.There be句型为特殊句型，附加疑问句的主语用there。5.在suppose guess think等后的宾语从句中，附加疑问句的主语与宾语从句保持一致。
归 纳
附加疑问句中主语的选择是关键，要掌握分辨主句中的主语，并了解其代词的表现形式。

(二)陈述部分含有动词have/has/had的附加疑问句
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为助动词，帮助构成完成时，附加疑问句中使用助动词+主语。
2.当have/has/had为实意动词“有”时，附加疑问句可用have/has/had或助动词do/does/did。
3.当have/has/had表示“吃、玩”等意义时，附加疑问句要借助于助动词do/does/did。
归纳：have/has/had具有助动词和实意动词两种功能，因此在使用中一定要分清楚。
