疑问句中谓语动词什么时候用do,does did ,什么时候用is are,was ,were
我要清楚,不要乱七八遭,清楚有调理

1. do, does,did 要根据时态. do, does 用于一般现在时,当一般现在时的句子中谓语动词为原形的话,改为疑问加do eg. They like English. ------- Do they like English? Lucy and Lily come from the UK. ------- Do Lucy and Lily come from the UK ?而当一般现在时的句子中谓语动词后加s/es,改为疑问要在句首加does,并且将谓语动词改为原形eg. he likes english. -------does he like english? he teaches us english. -------does he teach us english?did 用于过去时的一般疑问句,同样看谓语动词是否用了过去式,改时放在句首,谓语动词同样改为原形eg. they wanted to go home. -------- did they want to go home? he liked to stay at home before. -------did he like to stay at home before?特别注意的是要仔细掌握不规则的动词过去式,尤其是跟原形一样的,举两例eg. he read the novel last night. -------- did he read the novel last night? the book cost him 30 yuan. -------- did the book cost them 30 yuan.2.is are,was ,were简单的就是看句中有无这些词,有就提前放句首,后面的不变.具体而言is are 在一般现在时中eg. he is a student. -------- is he a student? they are from Class 9 --------Are they from class 9?在一般现在时的被动语态中eg. english is taught in the school --------is english taught in the school在现在进行时中eg. they are watching TV now--Are they watching TV now he is listening to the teacher -------is he listening to the teacher在现在进行时的被动语态中eg. he is washing his car. =his car is being washed by hm ----- is his car being washed by himwas ,were在一般过去时中eg. he was late for school yesterday -------was he late for school yesterday在一般过去时的被动语态中eg. the teacher gave him a pen = a pen was given to him by the teacher --------was a pen given to him by the teacher在过去进行时中eg.he was watching TV at nine yesterday -------was he watching TV at nine yesterday在过去进行时的被动语态中eg.he was doing his homework from 7 to 9 last night.=his homework was being done from 7 to 9 last night by him. ---- was his homework being done from 7 to 9 last night by him被动语态的知识可能你还不了解,若是的话现在可放在一旁,不必急于弄清,等你以后学到便能融会贯通打字很辛苦,盼能被采纳
