问题描述：
What are they doing?They_____(are playing,play) chess.
选词填空
答
are playing
如果帮到你，请记得采纳，O(∩_∩)O谢谢
答
are playing
因为问的问题他们正在干什么，be doing 表示正在干某事，所以回答也要用be doing!
如果提问的是：what do they do!可以用 play回答
答
are playing！！！
相信我，百分之百正确
另外再给你一个公式：现在进行时 主语+ be动词+ v。-ing+ 其它!!!!
还有什么疑问吗，我会帮你解决
答
填 are paying
用现在进行时与问句对应。
答
are playing
问句是现在进行时,答语也用现在进行时
祝你学习进步,更上一层楼! (*^__^*)
