陈述部分+附加疑问部分
助动词、be动词或情态动词
1. 组成原则：前肯定后否定或前否定后肯定。
(1) 肯定式陈述部分＋否定附加疑问部分—He wants t g, desn't he? —N, he desn't.(2) 否定式陈述部分＋肯定附加疑问部分—Yu aren't a student, are yu? —Yes, I am.(3) 含有否定词的陈述部分＋肯定附加疑问部分He seldm gives in t difficulties, des he?(4) 祈使句＋附加疑问部分Lk at the screen, will yu?din'zi
2. 常用的四种组成类型
陈述部分带有seldm, hardly, never, rarely, few, little, nwhere, nthing等否定词或半否定词时
注意：如果陈述部分的否定词带有否定前缀，那么，该陈述部分作肯定处理，附加疑问部分一般仍用否定形式。如：He was unsuccessful, wasn't he?Tm dislikes the bk, desn't he?
1. He desn’t knw her, ↗des he? （表疑问）2. I can’t cme in, ↗ can I ?（表请求）3. They are cming, ↘aren't they? （表求证）4. Let’s g, ↘ shall we?（表征求同意）
陈述部分一般用降调，而附加疑问部分既可以用升调也可以用降调，含义不同。通常情况下，升调多表示疑问或请求；降调多表示求证或希望对方同意。
1.当陈述部分的主语是名词时，附加疑问部分的主语必须用人称代词来代替。2.当陈述部分的主语是指示代词this、that时，附加疑问部分的主语用it代替；指示代词是these、thse时，附加疑问部分的主语用they代替。3. 陈述部分若用指人的不定代词everyne、everybdy、smene、n ne、smebdy、nbdy等作主语时，其附加疑问部分的主语常用they，有时也用he；若陈述部分用不定代词smething、nthing、everything等作主语，附加疑问部分的主语用it。
Yur brther has gne t the library, hasn't he?
That isn't a useful bk, is it?These are grapes, aren't they?
N ne is at schl nw, are they?Everything is ready nw, isn't it?
4. 当陈述部分为主从复合句时，附加疑问部分一般应与主句的主语和谓语动词保持对应关系。 注意：但当陈述部分的主语是I，谓语是think, believe, suppse, expect, imagine, suspect 这类动词时，附加疑问部分则往往与从句中的主语和谓语动词保持对应关系，但要注意否定的转移。
She says that I did it, desn't she?I tld them nt everybdy culd d it, didn't I?
I suppse that he's serius, isn't he?I dn't think she cares, des she?
5. 陈述句子中的主语为动词不定式短语、动名词短语或其他短语时，疑问部分的主语通常用it。 6. 陈述部分为表示“存在”的There be ...句式时，附加疑问部分仍用there。7. 如果陈述部分是以代词ne作主语，附加疑问句中的主语在正式场合用ne，非正式场合用yu, 在美国英语中，在非正式场合还可以用he。

8.当陈述部分的主语是I, 而句子又是用来征询对方的意见时, 附加疑问句中的主语用yu。9. 陈述句主语由或者连接，反意疑问句部分的主语根据实际意义而定。
