8、 .若陳述句中沒有上述這些詞，我們需要判斷時(shí)態(tài)和人稱，將do，did，does放與句首用于疑問，如：陳述句：He plays basketball well.他籃球打的很好。疑問句：Does he play basketball well? 他籃球打的好么？怛|典例精講例1.根據(jù)中文提示，完成句子。 我將會(huì)把這封信寄給她。例2.將陳述句轉(zhuǎn)換為否定句。1.1 have a lot of money.(轉(zhuǎn)換為否定句)2.

16、你是否獲得了新的知識(shí)了呢?總結(jié)一下，本節(jié)課帶給你哪些收獲?疑問句課堂導(dǎo)入IIIPIIrilIIIPIIDo you have the time ?”可不是有沒有沒有時(shí)間”你有空嗎”英文表達(dá)應(yīng)該是Do you have time ?”或者我們還可以說(shuō)：Do you have a minuteAre you availableIlIIIICan you spare some timeIIUKIIIIIIIIAlzPl知識(shí)結(jié)構(gòu)一、疑問句之一般疑問句所謂一般疑問句，就是可以用yes或no來(lái)回答的疑問句。1. 肯定形式的一般疑問句此類一般疑問句的結(jié)構(gòu)為：“連系動(dòng)詞be/助動(dòng)詞/情態(tài)動(dòng)詞+主語(yǔ)+動(dòng)詞原形+

17、其他？ ”。如:Is he a good student?他是一個(gè)好學(xué)生嗎 ？Yes, he is.是的，他是。No， he isn t.不，他不是。Does he go to school by bike? 他騎自行車去上學(xué)嗎 ？Yes, he does.是的，他騎。 No, he doesn t.不，他不騎。2. 否定形式的一般疑問句此類一般疑問句主要表示反問或驚訝，通常在連系動(dòng)詞be，情態(tài)動(dòng)詞或助動(dòng)詞后加not的縮略式n t,并放在句首。如：Aren t you a writer?難道你不是作家嗎 ？No， I m not.是的，我不是。3. 用yes, no之外的詞回答的一般疑問句一般

18、疑問句也可用其他表示肯定或否定的詞回答，女口： certainly , sure, of course，I think so，all right，certainlynot，not at all， never， sorry， not yet， I m afraid not 等。Would you mind my joi ning your talk?我加入你們的討論，你們介意嗎？Of course not.當(dāng)然不介意。二、疑問句之特殊疑問句以疑問詞開頭的疑問句叫特殊疑問句。特殊疑問句的基本結(jié)構(gòu)是“疑問詞+一般疑問句”。常見的疑問詞有 what，who，whose，which，when，where

19、， how， what time，what color， how much，how many，how long， how often，how soon 等。1. 特殊疑問句的語(yǔ)序疑問詞作主語(yǔ)時(shí)，句子的語(yǔ)序與陳述句的語(yǔ)序相同。當(dāng)疑問詞作句子的賓語(yǔ)、狀語(yǔ)等時(shí)，應(yīng)用“疑問詞+一般疑問句”結(jié)構(gòu)。如：Who will give us a talk?誰(shuí)將給我們做報(bào)告？ （who作主語(yǔ)）When do you get up every day?你每天什么時(shí)候起床？ （when作時(shí)間狀語(yǔ)）2. 否定形式的特殊疑問句否定形式的特殊疑問句由“疑問詞+般疑問句的否定形式”構(gòu)成，主要表示勸告、建議或責(zé)備等。如：Why

21、蘋果。四、疑問句之反意疑問句1. 反意疑問句的特點(diǎn)1) 反意疑問句是由兩部分構(gòu)成的：前一部分是對(duì)事物的陳述，后一部分是簡(jiǎn)短的提問。即“陳述句+附加疑問句”。2) 反意疑問句前后兩部分必須遵循的原則是“三同一反”，即：人稱相同，動(dòng)詞相同，時(shí)態(tài)相同，前肯后 否，前否后肯。如：Mary is a worker， isn t she?瑪麗是工人，是不是 ？You won t go to the Summer Palace tomorrow， will you? 明天你不去頤和園，是嗎？2. 反意疑問句的答語(yǔ)對(duì)反意疑問句的回答，不管問題的提法如何，若事實(shí)是肯定的，就用yes回答；若事實(shí)是否定的，就用no

22、回答。注意在“前否后肯”的反意疑問句的答語(yǔ)中，yes意為“不”，no意為“是”。如：He isn t going to the meeting， is he?他不去參加會(huì)議，是嗎？Yes, he is.不，他要去。No， he isn t.對(duì)，他不去3. 常考的反意疑問句初中階段?？嫉姆匆庖蓡柧溆幸韵聨追N：1) There be句型構(gòu)成反意疑問句時(shí)，附加疑問句的主語(yǔ)應(yīng)用there。如：(x )There is a cat under the chair, isn t it?(V)There is a cat under the chair, isn t there?2) 如果陳述句中含有表示否

23、定意義的詞，女口never, hardly , few , little等，在構(gòu)成反意疑問句時(shí)，附加疑問句部分需用肯定式。如：I could hardly see the bird in the sky , could I?我?guī)缀蹩床灰娍罩械镍B，對(duì)嗎？Jim s never seen such a wonderful football match before , has he?吉姆以前從沒看過一場(chǎng)如此精彩的足球賽， 是嗎？【注意】若陳述句部分含有帶否定前綴的詞，如：unhappy, impossible, untrue, dislike等，應(yīng)把陳述句看作肯定句，構(gòu)成反意疑問句時(shí)，附加疑問句用

24、否定式。如：He dislikes volleyball, doesn t he?他不喜歡排球，是不是？Jenny looks unhappy today, doesn t she?今天珍妮看起來(lái)不高興，是不是？3)祈使句之后的附加疑問句一般祈使句之后的附加疑問句常用will you? ”或won t you? ”。例 Don t make so much noise, Lily ,A. do you B. don t you C. will you否定祈使句之后的附加疑問句應(yīng)用“以let s開頭的祈使句的附加疑問句常用 you? ”。例 Let s go to the cinema to s

28、rday. 可知可以幫忙”。例2A本句為選擇疑問句，在問句中提供了Coke與tea,而答語(yǔ)中只出現(xiàn)了coffee,由此可判斷這里是對(duì)兩者的否定，故用 neither。例3B餾罰句意：“他以前從來(lái)沒有去過加拿大，是嗎？ ” “抱歉，我不知道?！贝祟}考查反意疑問句，要遵循“前否后肯”原則，因?yàn)榍懊嬗蟹穸ㄔ~never，且前面的s是has的縮寫。例4D餾更I這里是“前肯后否”的反意疑問句，根據(jù)答語(yǔ)第二句句意“我來(lái)自倫敦附近的一個(gè)小鎮(zhèn)”可知，我 的確是從英國(guó)來(lái)的，與上文事實(shí)相符，故用Yes, I do.回答。冃達(dá)標(biāo)檢狽L1.
