句型转换题可以有效地帮助学生理解并巩固所学的句型，掌握各种句型的内在含义，帮助学生掌握各种句型的句式结构和不同句式的变化技巧，理解并掌握句型与句型间的相互转换规律。学生如能掌握句型转换的解题技巧，对于他们理解并运用所学句型，形成语感，进而培养他们的英语综合运用能力有着极其重要的意义。在日常英语教学中，每位英语教师都十分重视对学生句型转换解题技巧的培养，因为他们深知：只要学生掌握了句型转换的本质含义和解题技巧，不仅能熟练地运用各种句式和句型进行口头表达，还能够熟练地做句型转换题，把所学的句型和句式举一反三，灵活运用，这样就把口头运用转换成了笔头运用，从而培养了学生的综合语言运用能力。
笔者在二十多年从事一线英语教学的过程中，摸索出了一些句型转换题的解题技巧，现结合句型转换的常见题型作如下归纳。句型转换题为非选择性试体，常见的句型转换有：把肯定句式变成否定句式；陈述句变一般疑问句；对一般疑问句作肯定、否定回答；单数句变成复数句；对划线部分提问；同义句转换等。
1把肯定句式变成否定句式
含有be动词（am， is，are，was，were）、助动词（have，has，had）和情态动词（shall，will，can，may， must，could，would，shoud）的句子改为否定句时，只须在这些动词后加not，含行为动词的句子改为否定句时要借助动词（do/does/did），根据谓语动词的人称数及时态，确定加do not，does not或did not。确定之后，将其加在谓语动词之前，并将不是原形的谓语动词还原为原形，而且还要将some变为any。如：
（1）He was late for school yesterday.→
He wasn’t late for school yesterday.
（2）Jim is a teacher.→
Jim isn not a teacher.
（3）LiPing can speak English.→
LiPing can not speak English.
（4）I have been to Kunming.→
I have not been to Kunming.
（5）She does the housework every day.→
She doesn’t do the housework every day.
2把肯定句式变成一般问句
含有be动词、助动词和情态动词的句子改为一般问句时，只须将be动词、助动词和情态动词调到句首然后改大小写，最后将句号改为问号。简单概括为：“一调，二改，三问号”。含行为动词的句子改为一般问句时要借助助动词，先根据主语的人称，数及时态在句首加do/does/did，然后改大小写，最后将句号改为问号。而且还要将some变为any。简单概括为：“一加，二改，三问号”。如：
（1）There’s something to eat in the cupboard.→
Is there anything to eat in the cupboard？
（2）They will go to the park.→
Will they go to the park？
（3）He translated the book into English.→
Did he translate the book into English？
（4）Kate does morning exercises every day.→
Does kate do morning exercises every day？
3单复数的变换
单复数的变换要注意代词、名词、谓语动词的相应变换。如：
That bus is very old.（变成复数句）→
Those buses are very old.
4做就划线部分提问（将陈述句改为特殊疑问句）
4.1一般分为以下三个步骤
（1）先把划线部分换成相应的疑问词。
（2）将剩余部分改为一般疑问句。
（3）将疑问词和一般问句加在一起。
如：
My grandma is not very well.
第一步，选定疑问词为how.
第二步，将剩余部分改为一般问句为is your mother？
第三步，将疑问词和一般问句加在一起结果是How is your mother ？
4.2对谓语提问。划线部分是谓语时，无论是及物动词带宾语或是不及物动词，问句都以what开头，并以do的适当形式代替谓语动词。同时，助动词也要根据需要变化形式。如：
（1）He goes to school every day.
1）What
2）Does he go to school（do） every day？
3）What does he do every day ？
（2）We shall play football tomorrow afternoon.
1）What
2）will you play football（do） tomorrow afternoon？
3）What will you do tomorrow afternoon？ （3）They are singing in the classroom？
1）What
2）Are they singing（doing） in the classroom？
3）What are they doing in the classroom？
4.3就宾语提问。就宾语提问时，表示人的疑问词用whom或who，表示物的疑问词用what或which；就介词宾语提问，通常要和介词一起提到句首。但在固定介词结构中的介词不提前。如：
（1）He prepares his English lessons every day.
1）What
2）Does he prepare his English lessons ever day？
3）What does he prepare every day？
（2）He is going to live with his grandfather after his parents go abroad.
1）With whom
2）Is he going to live with his grandfather after his parents go abroad？
3）With whom is he going to live after his parents go abroad？
（3）I’m looking for my teacher.
1） （for） who（m）
2）Are you looking for your teacher？
3）Who are you looking for？（=For whom are you looking？）
4.4就定语提问。就修饰主语的定语提问，问句的语序不变；就修饰宾语或表语的定语提问，必须把代替它的疑问词和它所修饰的词一起提到句首。问谁的用whose，问哪个用which或what，问数量用how ？many或？how much。如：
（1）This is my bike.
1）Whose
2）Is this your bike？
3）Whose bike is this？
（2）The boy in white is my brother.
1）Which
2）Is the boy in white your brother？
3）Which boy is your brother？
（3）He bought three books last Sunday.
1）How many
2）Did he buy three books last Sunday？
3）How many books did he buy last Sunday？
4.5就状语提问。就状语提问时，表示时间的疑问词通常用when，表示地点的疑问词用where，表示原因的疑问词用why，表示程度的疑问词how。如：
（1）I met Mr.Smith at the park yesterday.
1）Where
2）Did you meet Mr.Smith at the park yesterday？
3）Where did you meet Mr.Smith yesterday？
（2）She got up at six this morning.
1）When
2）Did she get up at six this morning？
3）When did she get up this morning？
5变感叹句
将陈述句变成感叹句，要分以下几步：
第一步：在陈述句的谓语动词后将句子划断。如：The boxes are/very heavy.
第二步：斜线后的形容词、副词的修饰语要去掉，如上句去掉very。
第三步：若斜线后部分的中心词是形容词、副词，则在斜线后部分的前面加how。如果中心词是名词，就加what。
第四步：将陈述句句首的大写改为小写，将感叹句句首改为大写。
第五步：将陈述句句末的句号改为感叹号。于是上句应改为：How heavy the boxes are！又如：
They are happy to see each other.→
How happy they are to see each other！
6同义句转换
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。常见题型为；根据上句，写出一个意思相同（或相近）的下句，此类题内容复杂，涉及面广，常用的转换方法有：
（1）用同义词或词组替换。（通常上下句时态保持一致）。
A：The children had a good time in the park.→
B：The children enjoyed themselves in the park.
（2）用同义句型替换。例如：
A：I went to bed after I finished my homework.
B：I didn’t go to bed until I finished my homework. （3）现在完成时态中的一句多译。在现在完成时态中，结束性动词不能与时间段连用，必须改成相应的延续性动词。常见的动词转换有：buy—have， borrow—keep， die—be dead， open—be open， join—be in+组织/be a +成员， begin—be on， leave—be away from， close—be closed， arrive in/ get to/ come/go to—be in/at， finish—be over， go to sleep—be asleep，get up—be up.
例如：The old man died five months ago.
The old man has been dead since five months ago.
The old man has been dead for five months.
It’s five months since the old man died.
Five months has passed since the old man died.
（4）将疑问代词/副词引导的宾语从句可转化为“疑问句+不定式”结构。例如：
A：Could you tell me how I can get to the railway station？→
B：Could you tell me how to get to the railway station？
A：We don’t know what we should do next.→
B：We don’t know what to do next.
（5）将when/after/before/while/since/until引导的时间状语从句可转化为when/after/before/while/sine/until + doing…
例如：
A，They went home after they finished their work.→
B：The went home after finishing their work.
A：Mr Smith has taught English since he came to China.→
B：Mr Smith has taught English since coming to China.
（6）由so…that…引导的结果状语从句可转化为too…to do或…enough to do……例如：
A：The box is so heavy that I can’t carry it.→
B：The box is too heavy for me to carry.
或：The box isn’t light enough for me to carry.
A：The child is so old that he can go to school.→
B：The child is old enough to go to school.
（7）用并列连词neither…nor；either…or…；both…and…；not only…but also…连句。例如：
A：I haven’t seen a TV play for long， and Lily hasn’t either.→
B：Neither I nor Lily has seen a TV play for long.
A：Tom is good at maths， and he is good at French， too.→
B：Tom is good at both maths and French.
neither…nor…， either…or…和not only…but also…连接两个主语时，谓语动词依靠近它的主语而定，即“就近原则”，但是both…and用来连接两个主语时，谓语复数。
（8）主动语与被动语态的互变。 “主动”变“被动”实行“三变二不变”原则。“三变”即是主语，谓语和宾语的变化，“二不变”即时态不变，句式不变。例如：
A：They make watches in the town.→
B：Watches are made by them in the town.
A：I can finish the work before eight.→
B：The work can be finished（by me）before eight.
A：Do they grow rice in South China？→
B：Is rice grown in South China？
要做好句型转换题，还必须注意如下几点：
（1）注重掌握教材中的基本句和同一句子英语的不同结构表达技巧。
（2）弄清题意，明确题目考查点，了解题目所给句子与答句之间的关系。
（3）注意从多角度，全方位考虑问题，突破难点，注意复查，看是否按要求完成了转换。
通过上述的归纳和指导，可以理清学生的“依章办事”的解题思路，养成“有条不紊”的解题习惯，培养多角度思维解题的能力，从而全面提高学生的英语水平。
