    、陈述句:是用来陈述一件事情或表示一种看法,可分为肯定句和否定句两种形式。 1、谓语动词是be动词,助动词have, has, will,情态动词can等时,只要直接在这些词后面加not就构成否定形式。
   eg。 Lily has already read this new book。   (改为否定句) Lily ______ ______ this new book ________。
   2、谓语动词是行为动词而又没有助动词或情态动词时,必须在谓语动词前加助动词,一般现在时加助动词do ,第三人称单数加does,一般过去时加did,再和not构成否定结构。  必须指出的是:don't, doesn't, didn't后都用动词原形。
   eg。1)Jill has lunch at school every day。 (改为否定句) Jill _____ _____ lunch at school every day。
     2)The children had a good time at the party。 (改为否定句) The children ______ _____ a good time at the party。
   3)Rose didn't drink any milk this morning。  (改为肯定句) Rose ______ ______ milk this morning。
   二、疑问句:是用来提出问题的句子。 A。一般疑问句:以be动词, have /has/do等助动词、can/may等情态动词开头,以yes或no来回答的问句。 它的基本结构是:Be/Have /Has/Did等助动词(包括情态动词)+主语+谓语(包括表语)+┄?回答常用简略回答。
     1、谓语动词是be动词、助动词、情态动词时,只要直接把这些词置于句首,句末改成问号。 eg。 There's something wrong with his bike。
  (改成疑问句) ______ _____ _______ wrong with his bike? 2、谓语动词是行为动词时,必须在句首加上助动词Do、Does(三单)、Did(过去式)加上这些助动词后,句子中谓语动词必须用原形。
     eg。 1)Edison built a science lab himself when he was ten。 (改成疑问句) ______ Edison ______ a science lab himself when he was ten? 2)Those Japanese like Chinese food。
    (改成疑问句) ______ those Japanese ________ Chinese food? 注意:在把肯定句改成否定句或一般疑问句的时候,要注意句中是否有already、some、something、somebody等词,如果有也必须进行改变,already要改成yet,some、something、somebody等分别改成any、anything、anybody等。
    另外,在改成否定句的时候注意把too改成either,both改成neither,all改成none等。在改成一般疑问句的时候,常常把第一人称I、we改成第二人称you。
   B。特殊疑问句:以疑问代词或疑问副词开头,提出疑问的句子。 它的基本结构是:特殊疑问词+一般疑问句语序。  但是如果疑问词在句子中作主语或作主语的定语,就用特殊疑问词+陈述句语序。
  常用的疑问词有:what, who(whom), whose,which,when,where,how,why等,回答时针对问句中的代词和副词来回答,不用yes或no来回答。 1)对指物名词或谓语动词提出疑问,疑问词用what ①The twins were making a kite when their mother came in。
     (划线提问) ______ _____ the twins _____ when their mother came in? ②Mrs Turner asked her son to buy some eggs for supper。
   (划线提问) _______ ______ Mrs Turner ask her son ______ _______? 2)对名词前定语提出疑问,疑问词应用which,而且必须和名词连用。
     I'm going to take the shirt on the right。(划线提问) ______ _____ are you going to take? 3)对指人名词或代词提问用who,作宾语时提问用whom。
   eg。Li Ping,they,his father 4)对物主代词和名词所有格提问用whose。   eg。 Li Ping's coat→Whose coat my father→Whose father 5)对具体时间提出疑问,如 in the morning,last Sunday等,疑问词用when;对具体几点钟提问,疑问词应用what time。
     6)对具体地点提出疑问,疑问词应用where。 The pupils are having a picnic at the foot of the hill。
   (划线提问) _____ _____ the pupils having a picnic? 7)对表原因的从句提问,常见的有because引导的从句,疑问词应用why。   Xiao Cheng didn't go to the farm with us because he was ill。
   (划线提问) _______ _____ Xiao Cheng go to the farm with us? 8)对方式或程度等提出疑问,用疑问词How。   eg。
   go by bike like very much 9)对数量提出疑问,疑问词为How many,要注意how many必须跟名词的复数形式。 eg。 two hundred sheep→How many sheep 10)对价格提出疑问,疑问词用How much。
     eg。 I paid fifty yuan for the sweater。 ______ ______ did you pay for the sweater? 11)对时间长度提出疑问,疑问词应用How long。
   eg。 I've worked in that factory for two years。   (划线提问)96中考题 ______ _____ _______ you worked in that factory? 12)对时间频率,如 once a year, twice a week等提问,疑问词用How often。
   13)对具体次数,如 once, twice, three times等提问,疑问词用How many times。   eg。 ______ did he call you the day before yesterday?Twice。
   96中考题 A。What time B。How many times C。How much D。How long 14)对in+一段时间提问,疑问词一般用How soon。   eg。
