求助:关于博后合同的一个问题

我的博后合同里有一个条款不明白什么意思,请懂的高手帮忙解答一下. 非常感谢!

you are entitled to a contribution towards housing costs outside your place of residence of 75% to a maximum of 227 euro per month,as well as the reimbursement of your one-way ticket to the Netherlands.

房帖和报销机票？

每个月最多给你报227的房租，相当于报销来时机票，很清楚啊。不过这条只有第一年有效。
