1、句型转换题型解读第一部分01题型解读“句型转换”题主要有两大类：一是基本句式的转换；二是同义句的转换。基本句式的转换主要是指“肯定句、否定句、一般疑问句、特殊疑问句、反意疑问句和选择疑问句、祈使句、感叹句”的转换。01题型解读（一）肯定句、否定句和一般疑问句的转换（1）含有be动词(am,is,are,was,were)、助动词（do,does,did)和情态动词（can,could,should，will,would,may,might)的句子；肯定句改为否定句，直接在be动词、助动词、情态动词后面加not；肯定句改为一般疑问句时，一律将be动词、助动词和情态动前移到句首基本句式转换01题型

2、解读（一）肯定句、否定句和一般疑问句的转换（2）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、原因、数量等分别用：who，whom，whose，what，when，where，why，how，how many，how much，how often，how 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。改完后要注意检查句首首字母大写和句尾的标点符号。例如：I spend about half an hour a day reading EnglishHow long do you spend a day reading Engl

3、ish?基本句式转换01题型解读（二）选择疑问句和反意疑问句的转换（1）改为选择疑问句时，只需注意根据句子的内容用“or”连接两个并列的成分就可以了。He can sing.(用dance 改为选择疑问句)Can he sing or dance?基本句式转换01题型解读（2）反意疑问句的结构是“陈述句+简短问句”，必须记住“前肯后定”和“前否后肯”的规律和简短问句的主语必须用代词的要求。Tom likes playing football,doesnt he?Xiao Hong didnt like singing,did she?基本句式转换（二）选择疑问句和反意疑问句的转换01题型解读（

4、三）祈使句和感叹句的转换（1）改为祈使句时，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，后跟原形动词(主语是 I 或 we 时，句子开头用 let me 或 lets)。例如：You should remember his telephone number.Remember his telephone number,please.基本句式转换01题型解读（三）祈使句和感叹句的转换（2）改为感叹句时，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；强调的是形容词或副词，句首用How，后面必须紧跟形容词或副词，例如：The park is bea

5、utiful.What a beautiful park./How beautiful the park is.基本句式转换01题型解读同义句转换就是将所给的句子换个说法。这一题型包含的内容多，形式杂。有词汇的同义转换，句型的同义转换等。一般说来，同义句转换主要有以下几种形式：简单句之间的转换、二合一并成简单句、简单句与复合句的互换以及时态、语态的转换。同义句转换01题型解读（一）简单句之间的转换逐个翻译后，与原句进行对照，看缺少了哪个词或哪部分意思，然后再用与其意思相近的词、词组或句型去替换。例如：同义句转换I spent 50 yuan on the coat.I paid 50 yuan

6、 for the coat.My favorite lesson is English.I like English best.I spend about half an hour reading English in the morning.It takes me about half an hour to read English in the morning.01题型解读（二）二合一并成简单句把两个并列句中成份相同的部分用连词合并起来，常见的连词有neithernor,eitheror,bothand,not onlybut also,enough to,tooto,sothat,as

7、soon as 例如：同义句转换He hasnt been to France.She hasnt been to France either.Neither he nor she has been to France.Mrs Smith is my teacher.She is also my good friend.Mrs Smith is not only my teacher but also my good friend.01题型解读（三）简单句与复合句的互换1.用不定式、介词短语、名词短语、分词性短语替换；2.将宾语从句简化为“疑问词+不定式”；3.将sothat(suchthat

8、)引导的状语从句简化为含有tooto(或enough to)的简单句；4.if 引导的状语从句简化为“祈使句，and(or)+句子”。例如：同义句转换01题型解读（三）简单句与复合句的互换I hope that I can see you soon.He is so young that he cant go to school.She didnt go to the bookshop yesterday,she went to the library instead.If we plant the seeds in the soil,they will grow.同义句转换I hope to

9、 see you again.He isnt old enough to go to school.She went to the library yesterday instead of the bookshop.Plant the seeds in the soil,and they will grow.01题型解读（四）时态、语态的转换 在解答时态转换题时，先找到时间状语，再确定句子的时态；遇到主动和被动句相互转换的时候，一定要注意句子当中人称和数的变化。例如：同义句转换I have watered grandpas apple tree.Grandpas apple tree has
