陈述句变一般疑问句的方法：
句中有动词be( am ,is ,are ,was ,were),情态动词（can / could ,may ,must ,will ,would 等）,助动词（如完成时态中的HAS / HAD ） ,变一般疑问句直接把这些词提到句首； 否则在句首加助动词Do ,Does （主语第三人称单数）,Did （一般过去时）,原来的动词要还原；另外,句中有SOME 是一般改为ANY .有already 时要改为yet （且放在句末）
陈述句变否定句的方法：
句中有动词be( am ,is ,are ,was ,were),情态动词（can / could ,may ,must ,will ,would 等）,助动词（如完成时态中的HAS / HAD ）,变否定句时直接在这些词后加NOT ；否则要加助动词Do ,Does （主语第三人称单数）,Did （一般过去时）,原来的动词要还原；另外,句中有SOME 是一般改为ANY ,如果有AND 要改为OR,（因为否定句中的并列要用OR）already 改为yet（且放在句末）；祈使句的否定句是直接在句首加Don’t ; ( 如Open the doo r,please .-> Don’t open the door ,please .) 不定式的否定句是在不定式前加NOT ,如 She asks the boy not to play in the street .
祝你假期愉快!加油!不明白再问!
Did they go home late yesterday?
ara we...?
助动词跟主语交换就行
首先这是一般过去时，所以应用助动词do的过去式did进行提问，原句中的过去式went 变回原形，其他不变。
Did they go home late yesterday？
第二句的划线部分是？
