1、 英语句型转换（一）.同义句转换知识点讲解（14 种类型）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（又称“词语替代法”），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 _.分析：答案为 everywhere。everywhere 与 here and there 都表示“到处”。2.The teacher always takes good care of the children in th
2、e school.The teacher always_ _the children well in the school.分析：答案为 looks after。take good care of 与 look afterwell 都表示“好好照顾”。3.The children are wearing beautiful clothes.The children are_beautiful clothes.4.Every day,Yao Ming receives E-mails from thousands of basketball fans.Every day,Yao Ming_tho
3、usands of basketball fans.5.Mr.Smith is working.Mr.Smith is_ _.答案：1.in 2.hears from 3.at work 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.Its clear that this visit is different from last time.Its clear that this visit is not the_ _last time.分析：答案为 same as。be different fro
4、m 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.分析：答案为 dont，more。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”。3.Chinese is more popular than Japanese.Japanese is_po
5、pular_Chinese.4.The runner couldnt catch up with the others in the race.The runner_ _the others in the race.5.A computer is more useful than a VCD.A VCD is not_useful_a computer.答案：4.less,than 5.fell behind 6.as，as 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 _ som
6、e money _ him.分析：答案为 borrowed，from。borrowfrom 意为“向借”；lendto 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.分析：答案为 be given back。被动句中含有情态动词 should，因此助动词用 be。2.It
7、 is widely accepted that more people use computers in the world today.Computers _ widely _ in the world today.分析：答案为 are，used。computers 是复数名词，助动词用 are。3.You must tidy your bedroom every day.Your bed room must be tidied every day.4.The farm grows cotton.Cotton is grown on the farm.四、非延续性动词与延续性动词的相互转换
8、 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.分析：答案为 has been away。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.分析：答案为 on for。has been 提示时态是现在完成时态，“fo
9、r+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。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.“Ive found my wa
10、llet,”he said to me.He _ me that he _ _ his wallet.分析：答案为 told，had found。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 _.分析：答案为 asked if/whether,before。此题是将疑问句的直接引语转换成间接引语。六、运用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。（1）.复合句化为简单句一般侧重于将从句变化为短语或词组，使句意简单明了。用不定式、介词短
11、语、名词短语、分词性短语等替换复合句中的句子；将宾语从句简化为“疑问词+不定式”；将 so that ，或 such that 引导的状语从句简化为含有 too to ，enough to 简单句；将 if 引导的状语从句简化为“祈使句，and（or）+一般将来时”的句子.（2）.必须注意的是，简单句变为复合句时，很多情况下是把宾语扩大为宾语从句，从句中使用一般将来时或“情态动词+动词原形”。如：1.We didnt go out for a walk because it was raining.We didnt go out for a walk _ _ the rain.分析：答案为 b
12、ecause of。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 couldnt go to sleep.He was _ _ _ go to sleep.分析：答案为 too excited to。将 sothat换成 tooto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.分析
13、：答案为 how you can。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.分析：答案为 after using。即将 after 引导的状语从句改写为 after 引导的介词短语。5.I hope that I can see you again.I hope to see you again.6.Please tell me where we show our tickets.Please tell me where to
14、show our tickets.7.If you dont hurry up,youll miss the early bus.Hurry up,or you wont catch the early bus.七、运用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 well miss the early bus._ we _ hurry,well miss the early bus.分析：答案为 If，dont。if 引导条件状语从句。2.The man gave us a talk last week.Now he will
15、give us another talk this week.The man _ gave us a talk last week _ _ us another talk this week.分析：答案为 who/that，will give。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 bothand，neithernor，eitheror，not onlybut also等将两个简单句合并为一个简单句。此时要注意的是，bothand连接两个主语时，谓语总是用复数，而 neither
16、nor，eitheror，not onlybut 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 cant speak Japanese well and Jim cant,either._ Tom _ Jim can speak Japanese well.分析：答案填 Neither，nor。neithernor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.分析：答案为 Bo
17、th，and。bothand的意思是“和（两者）都”。3.This store sells mens shoes,and it also sells mens clothes.This store sells _ _ mens shoes _ _ mens clothes.分析：答案为 not only，but also。表示“不仅而且”之意。4.He hasnt been to France.She hasnt been to France,either.Neither he nor she has been to France.5.The roon isnt very big.It can
18、t hold a lot of people.This room isnt big enough to hold a lot of people.6.Mrs Smith is my teacher.She is also my good friend.Mrs Smith is not only my teacher but also my good friend.九、变成含有宾语从句的复合句首先要判断所给句子是哪一类型（陈述句、特殊疑问句还是一般疑问句），然后确定所需要的连词，同时必须注意时态的对应和陈述句语序。1.She missed us very much.She told us.She
19、 told us that she missed very much.2.Is Mr Nobel a teacher?Could you tell me?Could you tell me if Mr Nobel is a teacher?3.Wheres the foreigner from?He asked.He asked where the foreigner is from.十、用以 it 作形式主语的句型进行转换不定式所表示的动作发出者一般是句子的主语，但有时却不是，这时不定式常会带上自己的逻辑主语，这一主语通常由介词 for 引出。1.He can finish the work
20、 easily.It is easy for him to finish the work.2.He found to sleep was very difficult.He found it was very difficult for him to sleep.3.To learn English well is not easy.It is not easy to learn English well.十一、利用某些典型句式或结构进行转换 这类典型结构如 sothat，tooto，enough to，notuntil，so do I 等。要在把握句意的基础上对原句进行概括表达，遇到困难要
21、多换个角度去思考，需要反复推敲才行。如：1.Jim wants to go boating and his parents want to go boating,too.Jim wants to go boating,and _ _ his parents.分析：答案为 so do。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.分析：答案为 didnt，until。notuntil 意为“直到才”。特别提示：so t
22、hat ，too to ，enough to 是初中英语教材中三个重要的句型结构，在一定条件下它们可以互相转换。so that 与 enough to 的转换当 that 引导的从句是肯定的，从句主语与主句主语相同时，so that 可转化为enough to 结构；若从句主语与主句主语不相同时，so that 可转化为enough for sb.to 结构.Tom is so old that he can go to school.Tom is old enoughto go to school.The box is so light that the child can lift it.
23、The box is light enough for the child to lift.当 that 引导的从句是否定的，从句主语与主句主语相同时，so that 可转化为enough to 否定结构；若从句主语与主句主语不相同时，so that 可转化为enough for sb.to 否定结构，但须注意的是，转换后的形容词（副词）要用其相应的反义词。The man is so old that he cant go to work.The man isnt youny enough to go to work.The desk is so heavy that I cant move
24、it.The desk isnt light enough for me to move.so that 与 too to 转换当 that 引导的从句是否定的，从句主语与主句主语相同时，so that 可转化为too to 结构；若从句主语与主句主语不相同时，so that 可转化为too for sb.to 结构。He is so young that he cant go to school.He is too young to go to school.The box is so heavy that I cant move it.The box is too heavy for me
25、 to move.enough to 与 too to 转换enough to 句式为否定式时，可以转换为 too to 结构，但转换后的结构中too to 的形容词（副词）要用其相应的反义词。He is not old enough to do the job.He is too young to do the job.Tom didnt walk slowly enough for us to keep up with him.Tom walked too fast for us to keep up with him.十二、用同义句改写 英语中有很多意义相同（相近）但结构不同的句型、句式
26、，这些句型大多是学习的重点常见的有：not as as 与比较级的转换；than any other 与最高级的转换；when(after,before)引导的从句与 not until 的转换；瞬间动词（come,go,leave,buy,die,begin,borrow ）的过去时与含有一段时间状语的完成时的转换；take,cost,spend,pay for 的转换；询问价格的几个句型的互相转换；what 引起的感叹句与 how 引起的感叹句的转换等。She spent 30 dollars on the English-Chinese dictionary.The English-Ch
27、inese dictionary cost her 30 dollars.She paid 30 dollars for the English-Chinese dictionary.She spent 30 dollars buying the English-Chinese dictionary.How clever the man is!What a clever man he is!How old are you?Whats your age?W e came home when it was six oclock.We didnt come home until/before it
28、was six oclock.十三、用派生词或一词多义改写此类题型可采用“词类转化法”，利用某些派生词或词性相异的词组来代替原句中的某些成分，此时句子结构一般会随之发生一些变化。例如：The snow was heavy last night.It snowed heavily last night.The foreigners have visited the Great Wall.The foreigners have been on a visit to the Great Wall.十四、用介词短语改写 My brother went to college when he was se
29、venteen.My brother went to college at the age of seventeen.Tommy didnt have breakfast and went to school.Tommy went to school without having breakfast.I usually walk to school.I usually go to school on foot.十五、形容词、副词三种等级之间的转换e.g.Henry is taller than the other students in our class.=Henry is the tall
30、est student in our class.此类题目需要学生能够熟悉形容词、副词的构成规律，能够灵活运用一些有关形容词和副词比较等级的句型结构，如：（1）more and more,（2）the+比较级+of the two;（3）The+比较级,the+(另一词)比较级。特别要清楚表示最高级范围的结构，如：（1）in+组织/单位，（2）of+与主语同类别的人或物。表示排除主语的结构，如：（10）the other+名词复数；（2）any other+名词单数。表示相同性质比较的结构，as+形容词/副词（原级）+as;not as/so as.。解题时注意交换句子主语，用反义词进行改写；
31、或者用比较级表示最高级含义。十六、“祈使句+and/or”结构与 if 条件状语从句间的转换e.g.If you run a little faster,youll catch up with your classmates.=Run faster,and youll catch up with your classmates.此类题目要注意句子的肯定与否定，正确使用 and 和 or。十七、陈述句与感叹句及两种形式感叹句间的转换e.g.The boy drew a very beautiful flower.=How beautiful a flower the boy drew1 =Wha
32、t a beautiful flower the boy drew!此类题目要求学生能够完全掌握 what 和 how 引导的感叹句的构成，并能灵活运用。（二）.句型转换专练（附答案）A.将下列句子改为否定句。(每空一词)1.They are cleaning the classroom.They cleaning the classroom.2.I can find my watch.I find my watch.3.She is wearing a sweater today.She wearing a sweater today.4.There are some bananas on
33、the table.There are bananas o n the table.5.There is a bottle and a glass under the chair.There _ a bottle _ a glass under the chair.6.She can speak a little Chinese now.She _ _ speak a little Chinese now.7.He has tea in the afternoon.He _ _ tea in the afternoon.8.They know me very well.They _ _ me very well.9.My sister likes meat very much.My sister _ _ meat very much.10.I think he is right.I _ _
