英语在疑问句中动词是否要用原形?
看时态：
1.一般现在时用原型.
2.进行时用动名词.
3.一般过去时用过去式.
4.一般将来时用be going to do或will do.
5.过去完成时用have+过去分词.
不一定
1 be动词， am/ is/ are, was/ were一般提前到句首
如： Are you in Class 1?
Was he at home yesterday?
Are you cooking now? （ 现在进行时： am/is/are +主语 + doing..)
Was he do...

2.情态动词 can, may, must, should等， 把情态动词提前到句首
如： Can you swim? ( can + 主语 + 动词原形）
3 行为动词的，需要助动词
如： Do you get up at six? Does he get up at six? （一般现在时： do/ does + 主语+动词原形）
Did you go shopping yesterday? （一般过去时： Did+ 主语+动词原形）
Will you go to the movies tomorrow? （ 一般将来时： will+主语+动词原形)
Have you been to the Great Wall? （ 现在完成时： have/ has +主语+动词原形)

是的，不管什么时态，在一般疑问句中由助动词变化，所以动词是原形
