参考答案

正确答案：B
解析：M: So, that's what's been keeping you so busy recently!
W: Yes, I've been tied up with my studies. You know I'm planning to go to the United States this coming summer, but I'm a bit nervous about my English.
Q: What is the woman busy doing?
男士说：“这就是让你最近这么忙的原因了!”女士说：“是的，我都被学习弄得焦头烂额了。你知道我们打算今年夏天去美国，但是又有点担心我的英语。”该题问“女士在忙什么”。女士说要去美国，又担心英语，那么她忙的肯定是英语学习了。故B项“复习英语”为正确答案。
