初中英语句型转换的解题方法 初中英语句型转换的解题方法 为了使学生能够又快又对地完成句型转换题，本人从网络上搜集了有关这一类题的解决办法，经过自己认真的分类和总结。现在把这类题的解决办法一文本的形式展示给大家： 一、由肯定句变为一般疑问句 由肯定句变为一般疑问句的规则是把助动词置于句子的主语之前而把句子变为疑问语序。解题时应把握以下几点： 1、句子的谓语动词如果是be动词，则把be动词直接提到主语之前。 （注：在肯定句和一般疑问句中主语的一、二人称要互换。） eg. (1) We are in Class 1, Grade 7 . → Are you in Class 1, Grade 7 ? (2) Hes polite and helpful . → Is he polite and helpful ? (3) There are some birds in the big tall tree . → Are there any birds in the big tall tree ? (4) Some Americans are going to visit our school next week . → Are some Americans going to visit your school next week ? (5) A new modern bridge is being built over the Changjiang River . → Is a new modern bridge being built over the Changjiang River ? 2、句子的谓语动词中如果有情态动词，则把情态动词直接提到主语之前。 eg. (1) They can park their cars in front of the supermarket . → Can they park their cars in front of the supermarket ? (2) Id like some more dumplings . → Would you like some more dumplings ? (3) Children must be kept away from fire . → Must children be kept away from fire ? 3、句子的谓语动词如果是现在完成时或过去完成时，则把时态中的助动词have、has或had 提到主语之前即可。 eg. (1) I have finished reading the interesting book . →Have you finished reading the interesting book ? (2) The old woman had been dead before her dauther arrived . → Had the old woman been dead before her dauther arrived ? 4、句子的谓语动词如果是行为动词的一般现在时或一般过去时，在改为一般疑问句的时候，根据主语的人称和单、复数，需要添加助动词do、does或did 。 eg.(1) We enjoy the football matches very much . → Do you enjoy the football matches very much ? (2) Her mother does some cleaning every morning . →Does her mother do some cleaning every morning ? (3)She went to see her doctor yesterday . →Did she go to see her doctor yesterday ? 注：在添加了助动词的一般疑问句中，行为动词一律为动词原形。 二、由肯定句变为否定句 由肯定句变为否定句的规则是在句中的助动词之后添加否定词not。如果句中的谓语动词的情况和上述1、2、3点相同，则直接在be动词、情态动词和have、has或had之后添加否定词not 。除了be动词的am词形外，否定词not可以和助动词缩写为“助动 词 + nt”。而如果句中的谓语动词是行为动词的一般现在时或一般过去时，则要先添加助动词do、does或did，再在其后添加否定词not，分别可以
