pose a risk to

pose a risk to 意为：可能对...造成伤害，是表示破坏/负面影响的表达。

这是risk作名词时的一个常用短语。在写作中非常常用，类似于另一个常用短语：pose a threat to 可能对...造成威胁

其中pose在这些短语当中表示 to create a difficult or dangerous situation, 常与problem/ difficulty困难，困境/ risk/ threat威胁等表示“问题”的词搭配。

也可将pose改为present。

比如以下这段话的pose no risk to：

high earners. And 92% of student debt is owed to the federal government, meaning defaults /dɪˈfɔːlt /拖欠  pose no risk to the financial system (see article文章). The real problem is that 11m Americans, many poor and non-white非白种人, and many duped into studying for worthless degress, struggle挣扎 to repay even modest /mɑːdɪst/ 适度的 debts.

And 92% of student debt is owed to the federal government, meaning defaultspose no risk to the financial system. 92%的学生债务是欠联邦政府的，这意味着债务拖欠对金融体系不会造成伤害。

再比如，气候变化可能会对环境造成危害，可以说：

Climate change poses a serious risk to the environment.

=Climate change pose a serious threat to the enviroment.

不需要在pose前面再加上may/might等表示推测的情态动词，因为risk本身就包含了不确定的语气。
