句子如下：

      Except for the shortage of teacher, the lack of classroom and relevant equipment is also what we are endeavouring to solve right now, which we will be so gratefulif you could bring some aid to relieve.

      请问这里的”which we will be so gratefulif you could bring some aid to relieve.”是否有搭配错误的情况？因为有人说grateful应该写成“grateful to sb for sth”。这样直接做形容词不行吗？
