可以呀
It is worth considering the problem
这个问题值得考虑
It（形式主语） is worth（系表结构） considering the problem（真正主语）
=It is worthwhile considering the problem
=It is worthwhile to consider the problem
= The problem is worthy to be considered
= The problem is worthy of being considered
=The problem is worth considering
