所谓同义句转换就是将一个句子用另一种形式表达出来,而且意思不变.因此,掌握的句型越多,做题就越方便、快捷、容易.但每种练习的方式总有一定的规律可循。
简单来说，所谓同义句的理解口诀：就是换句型不换意思。
一、运用同义词（组）进行转换
用同义词或同义词组对原句中的某些词或词组进行替换，注意转换后的词或词组的词形变化要与句子其他成分相适应。如：
1. That day we could see flowers here and there.
That day we could see flowers __________.
答案：everywhere
解析：everywhere与here and there都表示“到处”。
2. The teacher always takes good care of the children in the school.
The teacher always______ _____the children well in the school.
答案：looks after
解析：take good care of与look after…well都表示“好好照顾”。
二、运用反义词（组）的否定式进行转换
即用反义词或词组的否定式表达与原句相同的意思，主要考查学生对反义词（词组）的积累和换位思维的能力。如：
1. It’s clear that this visit is different from last time.
It’s clear that this visit is not the___ ___last time.
答案：same as
解析：be different from意为“与……不同”；the same as意为“与……相同”，其否定式与be different from同义。
2. I think wealth is less important than health.
I ___ think wealth is ___ important than health.
答案：don’t，more
解析：less important的意思是“没有（不及）……重要”；more important的意思是“（比）……更重要”，该结构与not连用，则表示“不比……更重要”。
另外，有的反义词即使不与否定词连用，而只需改变句子结构也可构成同义句。如：
He lent some money to his friend.
He friend ___ some money ___ him.
答案为borrowed，from
解析：borrow…from...意为“向……借……”；lend…to...意为“把……借给……”。两个结构意思相反，但若变换“借出者”与“借入者”的位置，则可转换为同义句。
三、运用不同语态进行转换
即运用主动语态与被动语态的变化来转换同义词，但此时要特别注意时态、动词一致性。如：
1. Everyone should give back his library books on time.
Library books should____ ____ ____ on time.
答案：be given back
解析：被动句中含有情态动词should，因此助动词用be。
2. It is widely accepted that more people use computers in the world today.
It is widely accepted that computers ____ widely ___ in the world today.
答案为are，used
解析：computers是复数名词，助动词用are。
四、非延续性动词与延续性动词的相互转换
即非延续性动词与延续性动词进行转换，此时往往会涉及时态的变化。如：
1. The manager left two hours ago.
The manager _____ ____ ____ for two hours.
答案:has been away
解析：leave为非延续性动词，不能与for two hours这样的一段时间连用，而改成be away这样的延续性动词后，则可连用一段时间。
2. The film began five minutes ago.
The film has been _____ _____ five minutes.
答案：on for
解析：has been提示时态是现在完成时态，“for 时间段”表示“持续（一段时间）”，常用在含有现在完成时态的句子里。
3. Mr Li joined the Party twenty years ago.
Mr Li _____ _____ _____ the Party for twenty years.
答案：has been in
解析：短暂动词join，意为“参加、加入（组织，政党）”，不能与延续时间状语连用，与延续性时间状语连用时，将join改成be in或be a member in…。
五、运用不同引语进行转换
即将直接引语变为间接引语或将间接引语转换成直接引语。此时还要注意相关时态、人称、动词、状语等相应的变化。如：
1.“I’ve found my wallet,” he said to me.
He _________ me that he _________ _________ his wallet.
答案：told，had found
解析：此题是将直接引语转换成间接引语。
2. “Did you see her last week?” he said.
He _______ _______ I had seen her the week _______.
答案：asked if/ whether, before
解析：此题是将疑问句的直接引语转换成间接引语。
六、简单句与复合句之间的转换
即将简单句变成同义的复合句或将复合句变成同义的简单句。如：
1. We didn’t go out for a walk because it was raining.
We didn’t go out for a walk _______ _______ the rain.
答案：because of
解析：将原因状语从句because it was raining改为表示原因的介词短语because of the rain。
2. He was so excited that he couldn’t go to sleep.
He was ______ ______ ______ go to sleep.
答案：too excited to
解析：将so…that…换成too…to…结构，原句的that从句为结果状语从句，改写句中的不定式仍表结果。
3. Now I will show you how to do the work.
Now I will show you ______ ______ ______ do the work.
答案：how you can
解析：即将原句中的“疑问词 不定式”结构转换成宾语从句。
4. You should put them back after you use them.
You should put them back _____ _____ them.
答案：after using
解析：即将after引导的状语从句改写为after引导的介词短语。
七、并列句与复合句之间的转换
即将并列句变成同义的复合句或将复合句变成同义的并列句。如：
1. Come on, or we’ll miss the early bus.
____ we ____ hurry, we’ll miss the early bus.
答案为If，don’t
解析：if引导条件状语从句。
2. The man gave us a talk last week. He will give us another talk this week.
The man _____ gave us a talk last week _____ _____ us another talk this week.
答案为who/ that，will give
解析：who/ that gave us a talk last week为定语从句，修饰先行词the man。
八、运用关联连词连接或合并句子
即运用关联连词both…and…，Neither…nor…，either…or…，not only…but also…等将两个简单句合并为一个简单句。此时要注意的是，both…and…连接两个主语时，谓语总是用复数，而neither…nor…，either…or…，not only…but also…连接两个主语时，谓语动词通常应与靠近的主语保持一致。如：
1. Tom can’t speak Japanese well and Jim can’t, either.
______ Tom ______ Jim can speak Japanese well.
答案：Neither，nor
解析：neither…nor…表示“……和……（两者）都不”，刚好与原句的两个否定结构的意思相吻合。
2. Alice has read the book and Peter has read it, too.
______ Alice ______ Peter have read the book.
答案：Both，and
解析：both…and…的意思是“……和……（两者）都”。
3. This store sells men’s shoes, and it also sells men’s clothes.
This store sells ______ ______ men’s shoes ______ ______ men’s clothes.
答案：not only，but also
解析：not only…but also…表示“不仅……而且……”之意。
九、运用某些典型句式或结构进行转换
这类典型结构如so…that…，too…to…，enough to，not…until…，so do I 等。如：
1. Jim wants to go boating and his parents want to go boating, too.
Jim wants to go boating, and ______ ______ his parents.
答案：so do
解析：句意为“……他的父母也一样（一样想去）”。
2. John went to bed after he finished his homework.
John ______ go to bed ______ he finished his homework.
答案：didn’t，until
解析：not…until意为“直到……才”。
