“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。

（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

（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：

→How long do you spend a day reading English

（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。

Xiao Hong didn't like singing, did she

（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“Don’t”开头，后跟原形动词(主语是 I 或 we 时，句子开头用 let me 或 let's )。例如：
You should remember his telephone number.
→Remember his telephone number, please.

（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：

→What a beautiful park. / How beautiful the park is.

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 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.

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neither…nor…,either…or…,both…and…,not only…but also…,enough to, too…to, so…that…, as soon as… 例如：
同义句转换
He hasn't been to France. She hasn't 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.

（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so…that…(such…that…)引导的状语从句简化为含有too…to…(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：

He is so young that he can't go to school.

→She went to the library yesterday instead of the bookshop .
→ Plant the seeds in the soil, and they will grow.

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 grandpa's apple tree.
→Grandpa's apple tree has been watered by me.
