她是哪一个系的？
4. Which department is she in? 她是哪一个系的？
我们都知道主修是用major这个字，简单地问法就是, “What's your major?”但是你也可以用 which field 或是which department来代替. 比如说有人来演讲，你想知道他是什么系的教授，你就可以问“Which department is she in?”或是“Which field is she in?”还有一种最口语问主修的问法，就是问人家 "What are you studying?" 就可以了。
像这种「大概多久」的问法，也可以用到approximately这个字。比方说：“Approximately how long will it take to arrive home?” (大概需要多久才到家呢？)
