To be done与being done的区别 done ,being ,to be done 作定语时的区别 既然有require doing sth,又有require sth to be done,那么有require being done吗 to done to be done to being done 三个表示什么时候?什么意to done to be doneto being done 三个表示什么时候?什么意思 有没有wait for being done be worth doing等于be worth to being done吗 有没有find sth.to be done这个结构 非谓语结构有没有TO BE DONE 结构 being done 和 be doing ;done ；doing ; be done ;to be done 的用法 请详细点 谢谢 英语 区分 doing to和 be doing,being done 和 to be being done .请帮我区分一下 doing to和 be doing,being done 和 to be being done . done与be done,being done都表被动语态,有什么区别 关于英语非谓语问题非谓语doing having done to do to have done to be doing being done have been done to be done to have been doing done doing,having done,to do,to have done ,to be doing,being done,have been done,to be done,to have been doin be well worth being done是否有这种用法
