be required doing和be required to do有什么区别吗？求高手指教，谢谢！

Question

如题所述

Answer 1

be required doing:表示正在做的事。you are reuired sitting here now.
be required to do 表示要做的事。you are required to sit here this afternoon.
归纳起来：V+ing表示在做的事，to V表示要做的事情。明白了吗？

Answer 2

你好，
1 英语中没有be required doing这个结构。只有require doing.
2 be required to do ----被要求做某事
例句
1 this house requires repairing :==this house needs to be repaired. 这房子需要修理。
2 We are required to work hard at school.在学校里我们被要求努力学习。本回答被提问者采纳

Answer 3

require doing 相当于 require to be done 结构。类似的有：want,need,be worth 等。
