glader还是moreglad

是more glad，例如：

1、At sight of the rainbow, the children were more glad than the parents.看见彩虹，孩子们比大人更高兴。

2、I am not more glad than you.我可没像你那样高兴。

3、M: Yes, more than glad to.男：是的，非常乐意。

4、Their ignorance gave them one more glad hour.

glader还是moreglad

glader是 glad的比较级， gladest是最高级。 所以要讲较高兴，可用more glader ,而不是单独在more 后加glade.或单独使用glader.
