是的，他们工作努力。/不，他们工作不

努力。—Theydon’tworkhard,dothey?—Yes,theydo./No,theydon’t.

不，他们工作努力。/是的，他们工作不

努力。一、附加疑问句主语要与前面陈述句主语保持一致。1.陈述句主语是that,this,those,these，附加疑问句的主语要用it或they。如：

ThisisTom’stextbook,isn’tit?Theseareyourbooks,aren’tthey?2.陈述句主语是表示人的不定代词，如anyone,someone,noone,everybody,nobody,somebody等，附加疑问句的主语通常用they或he。如：

Everyoneknowsthatwriter,don’tthey/doesn’the?3.陈述句主语是表示物的不定代词，如anything,nothing,something,everything

等，反意疑问句的主语用it。如：

Nothingintheworldisdifficult,isit?4.陈述句的主语是非谓语动词或主语从句，反意疑问句的主语用it。如：

Smokingisnotallowedhere,isit?Whathelacksiscourage,isn’tit?5.Let’s与Letus/me后的附加疑问句主语不同。如：

Let’sstartearlyinthemorning,shallwe?Letus/meknowyournewaddress,willyou?6.陈述句如果是therebe句型，反意疑问句的主语用there。如：

Thereislittlewaterleft,isthere?二、附加疑问句的助动词要与陈述句的助动词保持一致。1.在含Iam的陈述句之后，附加疑问句的助动词用aren’t。如：

Iamsupposedtobehere,aren’tI?2.陈述句谓语动词为haveto时，附加疑问句用do作助动词。当陈述句中have作“有”讲时，反意疑问句中既可用have作助动词也可用助动词do。如：

Wehavetotakeatest,don’twe?Hehasagoodmemory,hasn’t/doesn’the?3.陈述句的谓语动词含有usedto时，反意疑问句多用did作助动词。如：

SheusedtoliveinLondon,didn’tshe?4.陈述句中有情态动词must时：

1)must“一定，准是”，附加疑问句中助动词

要与must后动词照应。如：

Youmustbeveryexcited,aren’tyou?Youmusthavewaitedhereforalongtime,

haven’tyou?2)must“必须”，附加疑问句中的助动词用mustn’t。如：

Youmustleaverightnow,mustn’tyou?3)mustn’t“禁止”，附加疑问句中的助动词用must或may。如：

Youmustn’twalkongrass,must/mayyou?三、反意疑问句用肯定还是否定陈述句含有表示否定或部分否定意义的单词，如not,no,never,none,little,seldom,hardly,few,nowhere,nothing,barely,rarely,neither等，附加疑问句用肯定。如：Maryseldomgoestothecinema,doesshe?四、陈述句是主从复合句或其它句子时1.陈述句是主从复合句时，附加疑问句常重复复合句中主句的主语。主句中如果有Ithink/believe/suppose这样的主谓结构时，附加疑问句应与从句保持一致。如：

Younevertolduswhyyoudidn’tpasstheexam,didyou?Idon’tthinkshecares,doesshe?2.陈述句是并列句时，附加疑问句与后一个分句保持一致。如：

Theywereabsentyesterday,butMarywasn’t,wasshe?3.祈使句的附加疑问句常用will或can作助动词。祈使句为肯定句时，附加疑问句常用will/won’t/can/can’tyou；祈使句为否定句，附加疑问句则常用will/canyou。如：

Pleaseclosethewindow,will/won’t/can/can’tyou?Don’ttakephotosinthemeetingroom,will/canyou?4.感叹句的附加疑问句用否定形式。如：Whatafoolishchild(heis),isn’the?Howcleveraboyheis,isn’the?Whatbeautifulclothes(theyare),aren’tthey?Readtheconversation.Decidewhethertheintonationofthetagquestionsisrisingorfalling.Dave:Wonderfulgym,isn’tit?Jack:Er…yes.It’sgreat.Dave:Thisisn’tyourfirsttimehere,isit?Jack:Actually,itis.youcomehereoften,don’tyou?Dave:Yep.Atleastthreetimesaweek.Jack:You’velostsomeweight,haven’tyou?Dave:Yes.Allthatfathasbecomemusclenow.Ifyouwanttoloseweight,too.Irecommendusingthespinbike.Jack:OK,butitwon’tmakemetootired,willit?Dave:Maybeatfirst,butyou’llgetusedtoit.IusedtocomehereeverydaywhenIfirststarted.Jack:Oh,Idon’thavetocomehereeveryday,doI?Dave:No.Ofcoursenot.It’suptoyou,isn’tit?Listenandcheckyouranswers.Thenpractiseitwithapartner.提示：当附加疑问句是一个需要得到回答的问题时用升调，当附加疑问句仅用于希望得到对方的同意时用降调。Completetheconversationswithappropriatetagquestionsorcorrectanswers.Thenactthemout.1.A:It’snotgoingtorain,isit?
