Question

My demand is that the information referred to in my report"be" emaild to Mr.Brown
without delay中为什么要加“be”?

Answer 1

My demand is that the information referred to in my report be emailed to Mr.Brown without delay.

没有be,从句就没有谓语了,那是绝对不行嘀,因为referred to in my report 是information的分词定语,不是谓语.
关键为什么原形be,因为be是虚拟,demand语气嘛.
