6、t sent you the mail yet.二：疑问句questios分类：一般疑问、特殊疑问、反意疑问、选择疑问1. 一般疑问句 general questions : yes/no questions 型，一般可由yes/no来回答；11.一般疑问句的基本结构：A . be/助/情态动词(be can do have will 等)+主语+谓语/表语+(其他),句子要读升调；Eg：Are they your friends？Can you play basketball？ Can you swim to the other side？ Does he go to school on f
7、oot？Do you like English? Have you locked the door？Will you be free tonight？ 以上均可用yes、no来回答。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 didnt finish the work？You are fresh from America，I suppose？22.一般疑问句的回答：除yes、no外，也可用certainly，probably，perhaps，of course，all right，with pleasure等代替
8、yes，用never，not at all等代替no； Eg：Can you help me？Certainly.Could you please make less noise？All right，sir. Have you been there？Never.33.一般疑问句的否定式：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/Dont you believe me? Is it not / Isnt it a lovely day? Are you not / Arent you coming? Will you no
9、t /Wont you sit down? Is he not / Isnt he a doctor? Will he not /Wont he go with you?Does Helen not /Doesnt Helen like chocolate? 海伦不喜欢巧克力吗?B.否定疑问句并不单纯表示提问，它常常带有感情色彩; 否定疑问句的完全式比简略式所表达的语气更强烈些; 惊异、赞叹或责难等语气; 暗示提问者期待着肯定的回答; 表示邀请或建议;Eg：Havent you read the newspaper？ Wont he come？他不来了啊？ Shouldnt we start
10、now？ Wasnt it an interesting film？Wouldnt you like to go with me？ Wont you have a cup of coffee？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，Iam.不，我是 /No，I am not.是的，我不是Havent you read this book before？Yes，I have.不，我读过/No，I ha
11、vent.是的，我没有Dontyou play chess？Yes ，I do.不，我下棋 /No，I dont.是的，我不下棋。教你一招：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。 2. 特殊问句 special questions ：wh-questions型问句，when. where. what. who. why. which. whose.11.特殊疑问句的基本结构：A . 特殊疑问词+一般疑问句；即特殊疑问词+be/助/情态动词+主语+谓语/表语+(其他).
