问题描述：
My freeing Alice wanted to be a nurse when she was four years old. Last year she started her studies in a big hospital in Newcastle. She bad to work very hard. She went to classes every day and studied late at night. Then a really important day came: her first day in a ward. At _____ she was really helping sick people, not just sitting in classes or learning from books.
present or last
为什么
问题解答：
present
理由很简单 一开始的ward解释为病房，与后文联系起来看 说明Alice第一次在病房工作而不是坐在教室中学习，at present解释为现在如今等于now，填空句就解释为如今她是真正的在照料病人，与上下文都符合
这样应该可以了吧
present ,at present--当前
