下面我们具体讲一讲同义句转换的解题方法与技巧.
所谓同义句转换,是指用不同的词汇、短语及句型表示相同或相近的意思.它是中考命题的一大热点.现将常见的同义句型转换形式作一归纳,以期对同学们的中考复习有所帮助.

答案：1. in 2. at work
简析：英语中有不少同义、近义词（组）,在平时学习中要注意总结归纳.如：
enjoy oneself �� have a good time
look after �� take care of difficult �� hard
can �� be able to over �� more than
receive / get a letter from �� hear from
hardly �� almost not
二、用反义词（组）改写

Japanese is ______ popular ______ Chinese.
2. The runner couldn"t catch up with the others in the race.

四、二句并一句转换为简单句
1. Jim doesn"t like noodles, and Jack doesn"t, either.
______ Jim ______ Jack likes noodles.
2. Mrs Smith is my teacher. She is also my good friend.
Mrs Smith is _______ _______ my teacher _____ _____ my good friend.
答案：1. Neither, nor 2. not only, but also
简析：英语中常用“not only…but also…”,“either…or…”,“neither…nor…”,“both…and…”等连词把两个意义相关的简单句合并成一个简单句.解题过程中要注意连词的选用和主谓一致原则.除此之外,还可用“too…to…”,“enough to”等把两个简单句合并成另一简单句.如：
Tom is young. He can"t go to school.
→Tom is too young to go to school.
五、用派生词或多义词改写

It ________ ________ last night.
答案：snowed heavily
简析：句中名词snow和形容词heavy转化成了动词snowed和副词heavily.
六、并列句与复合句的互换

If we go on planting trees, the hill will _____ ______ in two _____.
答案：turn green, years
简析：含有祈使句的并列句,可转化为含if条件句的复合句.
七、简单句与复合句的互变

Do you know ______ _____ get the kite down from the tree?
答案：how to
简析：复合句转化为简单句一般侧重于将从句变化为短语或词组,使其句意简单明了.常见的转换方法有：（1）用不定式替换、用介词短语替换、用名词短语替换、用分词性短语替换；（2）将宾语从句简化为“疑问词+不定式”；（3）将含有“so…that… / such … that…”的复合句简化为含有“too…to… / 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”.
八、运用主动语态与被动语态互换
The farmers use tractors for farm work.
Tractors ______ _____ for farm work.
答案：are used
简析：当作主语的人或物是动作的承受者时,谓语动词用被动语态.注意掌握被动语态的构成.
九、直接宾语与间接宾语位置互换
His mother bought him a new pen.
His mother bought a new pen _______ him.
答案：for
简析：如果将表物的直接宾语放在及物动词后面,则表人的间接宾语前要加介词.
十、感叹句相互转换

_________ delicious that cake is.
_________ a delicious cake that is.
答案：How, What
简析：感叹形容词或副词时用how,感叹名词用what.
