请问这里可以用hope吗？
It is reported that UN mediators have worked out a plan which they hopewill be acceptable to both sides。不是说hope只有两种搭配，一种是：hope to do sth，一种是hope +that从句吗？可是这里的话，hope后面跟的是which，即plan.那这不就变成hope 直接加宾语，变成这样的句式：hope sth to do sth，可是没有这个句型啊！除非是wish，才有wish sth to do sth.所以我觉得这应该是把hope改成wish，才对。可是书上又这么写着hope。到底应该怎么解释呢?高手帮帮忙，不甚感激！！！
