1、英 语 句 型 转 换一、肯定句、否定句、一般疑问句的相互转换 这三种句型的转换有共同的规律可循，有几个要点必须牢记。我们可以把各种句式归为两大类：1、含有的be动词、助动词和情态动词的句子；2、只有行为动词的句子。第1类的句子，肯定句改为否定句时，一律在be动词、助动词和情态动词后加“not”，改为一般疑问句时，一律将be动词、助动词和情态动前移到句首（首字母大写）。肯定回答用“Yes”；否定回答用“No”。“Yes”或“No”后面的主语必须用代词，“No”后面必须用否定缩略式。如：将下列句子改为否定句、一般疑问句，并做肯定、否定回答：1.There are some computers i

2、n this school.(be动词)There arent any computers in this school.Are there any computers in this school?(Yes,there are./No,there arent.)2.Li Mings father can drive the car.(情态动词)Li Mings father cant drive the car.Can Li Mings father drive the car?(Yes,he can./No,he cant.)3.She has already finished his h

3、omework now.(助动词)She hasnt finished his homework yet.Has she finished his homework yet?(Yes,she has./No,she hasnt.)第2类句子必须借助助动词do;does;did。改为否定句，在行为动词前加dont（一般现在时态，主语是除第三人称单数之外的人称和数时）；doesnt（一般现在时态，主语是第三人称单数时）；didnt（一般过去时态）。改为一般疑问句时，在句首加Do；Does 或Did。肯定回答用“Yes”，后面动词用 do;does或did”；否定回答用“No”，后面动词用dont(

4、doesnt;didnt)”。如：将下列句子改为否定句、一般疑问句，并做肯定、否定回答：1.The children like playing games.The children dont like playing games.Do the children like playing games?(Yes,they do./No,they dont.)2.Mary usually goes to school on foot.Mary doesnt usually go to school on foot.(原第三人称单数改为原形)Does Mary usually go to school

5、 on foot?(Yes,she does./No,she doesnt.)3.Tom went to London yesterday.Tom didnt go to London yesterday.(原过去式改为原形)Did Tom go to London yesterday?(Yes,he did./No,he didnt.)二、特殊疑问句的转换 把句子转换为特殊疑问句，首先要确定划线部分的“疑问词”，人、物、时间、地点、数量、原因等分别用：who;whose;whom;what;when;where;why;how;how many;how much;how often;how

6、old;how long等。将相对应的疑问词放在句首，其余部分改为一般疑问句的形式，就是特殊疑问句。改完后要注意检查句首的首字母大写和句尾的标点符号。如：1.His licence number is 573968.Whats your licence number?2.Mike watches TV every evening.What does Mike do every evening?3.Jim studied in China last year.Where did Jim study last year?三、选择疑问句、反意疑问句的转换 改为选择疑问句时，只需注意根据句子的内容用“

7、or”连接两个并列的成分就可以了。如：Lucy is a student,Lily is a doctor.改为：Who is a doctor,Lucy or Lily?反意疑问句的结构是“陈述句+简短问句”，我们必须记住：“前面肯定；后面否定”和“前面否定；后面肯定”的规律和简短问句的主语必须用代词的要求。如：Tom likes playing football,_ doesnt he _?Xiao Hong didnt like singing,_ did she _?注意：祈使句的反意疑问句，一般都用will you?Lets-打头的一般用 shall we?四、祈使句、感叹句的转换

8、改为祈使句，必须记住：肯定的祈使句，是原形动词开头，否定的祈使句是“Dont”开头，后跟动词原形。如：1.You should remember his telephone number.改为：Remember his telephone number,please.2.Youd better not tell him the bad news.改为：Dont tell him the bad news.3.We can go there together.改为：Lets go there together.3.Jim studied in China last year.Where did

9、Jim study last year?3.Jim studied in China last year.Where did Jim study last year?改为感叹句，必须记住，强调的是名词，句首用What，What后的名词前可以有形容词形容词；强调的是形容词、副词，句首用How，后面必须紧跟形容词、副词，如 The park is beautiful.改为：What a beautiful park!或：How beautiful the park is!He studies English very hard.改为：How hard he studies English!1.你觉

10、得我们学校怎么样？How do you like our school?What do you think of our school?What do you like about our school?2.你最喜欢什么运动？What sport do you like best?Whats your favorite report?3.今天的天气怎么样？How is the weather today?Whats the weather like today?4.到吃晚饭的时间了。Its time to have supper.Its time for supper.5.劳驾，请问到邮局怎么

11、走？Excuse me,could you tell me the way to the post office?Excuse me,which is the way to the post office,please?Excuse me,how can I get to the post office,please?Excuse me,wheres the post office,please?6.请问你叫什么名字？Whats your name,please?May I know(have)your name?Could you tell me what your name is?7.祝你

12、中秋节快乐！I wish you a happy Mid-Autumn Day!Best wishes to you for Mid-Autumn Day!8.我叔叔修那台机器用了两个小时。It took my uncle two hours to repair the machine.My uncle spent two hours in repairing the machine.练习用不同的句式，表达不同的情感 有时为了表达不同的情绪、情感，需要适当变换一下句式，使语言更符合人物身份或当时的喜、怒、哀、乐、惊、恐、悲。最常用的是表示“客气、委婉”和“强调”。表示“委婉、客气”常可以借助“Im afraid”、“please”Im sorry等，如：1.I cant come on time.我不能准时来。Im afraid I cant come on time.恐怕我不能准时来。（比较委婉）否定句或强调句常常可以用来表示“强调”。如：1.Remember to lock the door.记着锁门。Dont forget to lock the door.别忘了锁门。（强调）2.You should go there one foot.你应该步行去那儿。Why dont you go there on foot?你为什么不步行去那儿？（强调）
