There are sb doing sth如果是被动语态该怎么办?如“There are many photos on display )by a man.意思是有许多一个男人拍的照片展出.照片被男人拍.处应填Ving吗?

there are 后面跟doing还是to doto do比如说there are sb.{ doing there be +sb+doing there be sb doing There are many students TO play games 为什么用to?不是There are sb doing sth there are sb doing sth中doing sth作什么成分 there be sb/sth doing imagine sb doing imagine sb's doing有什么区别 resist sb doing还是resist sb's doing There is sb. doing sth.是什么意思 What are you doing there? What are you doing there? wrong的用法?there's something wrong with sb. in doing sth.是否有这样的用法? admit one's doing还是admit sb doing? 用there is sb /sth doing sth,stop sb (from) doing sth造句 sb in doing sth 是there is nothing wrong with sb in doing sth mind sb doing sth和mind sb's doing sth都对吗?有哪些词可用sb' doing there be sb.do sth 还是there be sb.doing sth.有何区别 there be sb doingthere be sb doing一定吗?也就是说如果是这样,there are many people waiting for their trains yesterday,还给几个例子你们搞错了，我的意思是，如果是过去时，也可以用sb doing？如上例there are many
