在前文英語反義疑問句21種用法（21=1+2+3+4+5+6）（上篇）中，我們一起學習了反義疑問句的1個基本規(guī)則以及20種特例中的2否定和3種I，今天我們來看剩余特例（思維導圖如下）。

反義疑問句=陳述句+由陳述句而來并簡化的一般疑問句。附加問句由前面陳述句而來，所以其主語、時態(tài)、動詞要與陳述部分保持一致，但為避免用詞重復，主語必須用相應人稱代詞。

4種主語：

1.陳述句主語是表人的不定代詞everyone/everybody, someone/somebody, no one/nobody, none。問句主語通常用they，也可用he。

Nobody was there, was he/were they?

注意：one作主語，后句用one或you。One can't be too careful, can one/you?

2.陳述句主語是表物的不定代詞everything, anything, something, nothing。問句主語用it。

Nothing has been taken away, has it?

3.陳述句主語是指示代詞this/that, 問句主語用it。（these/those→they）

This is a desk, isn't it?

4.陳述句主語是不定式,動名詞，或名詞性從句時，問句主語用it。

To learn/Learning English well is important, isn't it?

What he said is true, isn't it?

5種句式：

1.倒裝句。There are many books to read, aren't there?

2.祈使句。

1) 肯定祈使句。

Be sure to write to us, will/won't/would/can/could you?

2) 否定祈使句。

Don’t move the chair, will you?

3) Let祈使句。

Let’s take a walk after supper, shall we?（晚飯后散個步，我們一起去好嗎？表建議）

Let us have a look at your book, will you? (讓我們看一下你的書，你愿意嗎？表請求）

3.感嘆句。問句用否定和一般現(xiàn)在時，主語取決于感嘆的對象并用相應代詞，

What a sunny day (it is), isn't it?

How quickly the boy runs, doesn't he?

4.并列復合句=簡單句1+并列連詞+簡單句2。對并列連詞（如and,but, or, for, so）后的句子進行反問。

We must learn English well or we can't adjust to the new era, can we?

5.主從復合句=主句+從屬連詞+從句。通常對主句反問（主句是I think…對從句反問）

I told him it was not that easy, didn't I? 我告訴過他沒那么簡單，我沒說過嗎？

6種情態(tài)助動詞：

1個當做實義動詞：陳述句中有have to，問句用do（does/did）代替have。

She had to give up the plan, didn't she?

2個實義&情助：need和dare作實義動詞時，問句用do相應形式。作情態(tài)助動詞時，問句中把need/dare提前。

He needn't say sorry to me, need he?

=He doesn't need to say sorry to me, doesn't he?

3個當做情態(tài)助動詞：即問句中直接把助動詞提前。

We'd better not tell him, had/should we?

Such things ought not to be allowed, ought/should they?

He used to drink a lot every day, didn't/usedn't he?

must的4種用法：

1)must有“肯定”的意思，表把握比較大的推測。既可表對現(xiàn)在情況推測（+do）：

He must work harder than before，doesn't he?

注意：must+be和have時的用法。

He mustbe good at math, isn't he?

He must have another account, doesn't/hasn't he?

2)must表肯定也可用于對過去情況的推測（+have done）：

They must have all gone home, haven't they? （無表過去的時間狀語，強調動作的完成）

You must have met him last week, didn't? (有表過去的時間狀語，強調對過去的推測）

3)must還有“必須”的意思。反義疑問句用mustn't.

You must work hard next term, mustn't you?

must表必須時的否定形式mustn't 意為“禁止” ，反義疑問句用must。

You mustn't stop your car here, must you?

4)must還有“有必要”的意思，問句用needn't.

They must finish the work today, needn't they?

注意：以上共出現(xiàn)了7個情態(tài)助動詞，但是have to是當做實義動詞來用，所以在體系中歸結為6個。

反義疑問句的這21種用法，我是按照難度由低到高同時重要性由高到低的順序排列的，對于絕大多數(shù)英語學習者來說，記住1條基本規(guī)則足矣。
