1、1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 better3、助动词：have, has, hadB. 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
2、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
3、 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 oclock every day. Do you get to school at six oclock every
4、 day?2. 句中第一个动词是三单形式时，在主语前加上 does，原来2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
5、，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
6、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 yearsDo you have taught English here for two years?（Wrong ）Have you taught
