英语句型转换之二
——肯定句变一般疑问句的方法
A. 请同学们记住以下单词：
1、be动词的五种形式：am, is, are, was, were；
2、情态动词：can, could, may, might, must, shall, should, will,would,
need, had better
3、助动词：have, has, had
B. 一般疑问句基本结构为：
Be动词或助动词或情态动词+ 主语+ 谓语+ 动词+ 其他?
C. 变一般疑问句的口诀有二：
1. 一调二改三问号；
2. 一找二改三问号。

D. 具体方法如下：
一、be动词，情态动词和助动词直接调到主语前
原句中含有be动词(am, is, are, was, were) 和情态动词(can, shall, will, may, should, would, might, had better等)时，把他们直接调到主语前。

如：
He teaches English.---- Does he teach English?
1. He is a teacher. →Is he a teacher?
2. Li Lei can speak English. →Can Li Lei speak English?
3. They will go to the aquarium if it is fine tomorrow.
→Will they go to the aquarium if it is fine tomorrow.
4. There were many students in the classroom.
→Were there many students in the classroom?
二、原句中没有be动词、助动词或情态动词时，要根据下面不同情况在主语前加助动词do, does, did。

1. 句中第一个动词是原形时，在主语前加上do。

如：
I get to school at six o'clock every day.
→Do you get to school at six o'clock every day?
2. 句中第一个动词是三单形式时，在主语前加上does，原来的动词
三单形式改为动词原形。

如：
He teaches English. →Does he teach English?
3. 句中第一个动词是过去式时，在主语前加上did，原来的动词过去式改为动词原形。

如：
The children had a good time in the park last night.
→Did the children have a good time in the park last night?
三、肯定句变一般疑问句的几点注意
1. 肯定句变一般疑问句时，除上述变化外，句中其他词语也可能随之改变，如将some改为any，something改为anything, my改为your, I改为you，already、still改为yet等。

如：
There are some apples in the tree.。

→Are there any birds in the tree?
The dentist has already seen the moive.
→Has the dentist seen the moive yet?
2. 需要分清do, does, did, have, has, have, had等是实义动词还是助动词。

如果是助动词，则把它们直接调到主语前，如果是实义动词，则在主语前面根据实际情况加do, does或did。

如：Mary usually does some reading on Saturdays.
→Does Mary usually any reading on Saturdays?（Wrong）
→Does Mary usually do any reading on Saturdays?（Right）
I have taught English here for two years
→Do you have taught English here for two years?（Wrong）
→Have you taught English here for two years?（Right）
