B:陈述句亦可用作一般疑问句，多用在 非正式文体中，句末有问号，用升调；Eg ： Somebody is With you ？ He didn ' t finish the WOrkYOu are fresh from AmeriCa Isuppose?22.一般疑问句的回答：除 yes 、no 夕卜，也可用 Certainly ，PrObabIy ， perhaps ，of course, all right ，With PIeaSUre 等代替 yes,用 never ，not at all 等代替 no ；Eg ： —Ca n you help me? —Certai nly.—Could you PIeaSe make less noise —All right ，sir. —Never.A. 一般结构：系/助/情态动词+not+主语； 也可为：系/助/情态动词+主语+not 。

Eg ： Do you not/Don ' t you believe me?

Won t you have a CUP of coffe?44.一般疑问句否定式的回答：否定的一般疑问句的答语中， yes 的含义为 不”，no 的含义为 是”，但在回答这类句子时，应该注意 yes 后接肯定结构，no 后接否定结构，这和汉语习惯不同。

Eg ： —Are you not Mr Smith ? —Yes I am.丕，我是 // —No, I am not.是的,我不是—HaVen' t you read this book before —Yes I have 不，我读过 // —No, I haven 是的，我没有一Don' you play CheSS ) —Yes , I do.不，我下棋 // —No, I don '是:的，我不下棋。

教你一招：I 在这样的答语中，只要根据实际情况来判断，如果事实上是，就用肯定的结构，前面接yes ；如果事实上不是，就用否定结构，前面接 no ；但此时的yes 、no 应翻译成反义的中文。
