Question 20 is based on the passage you have just heard.

听力原文：

    Katherine loved Facebook. With Facebook she could stay connected with her family no matter how far away they were. She could see their photos and read their status updates. With Facebook, she could keep her relatives up-to-date on what she was doing.（19）Another thing Katherine loved about Facebook was that she didn’t have to think about time zones when updating family. Whenever she called her parents or other relatives, she always had to think about the time difference so that she wouldn’t wake someone up or call when she knew they were at church. Facebook was so convenient.

    When Katherine joined Facebook, some of her classmates at high school started to add her as a friend. At first, this didn’t bother her.（20）She loved learning about the success of people she knew when she was just a teenager. She loved finding out people were getting married, having babies, and traveling.

    （21）Soon however, Katherine found herself comparing herself with the people she was reading about on Facebook. It began to make her feel bad that some people seemed to be doing so much better than she was. She was also spending a lot of time on Facebook. It took a lot of time and energy to keep up with everyone’s status updates.

    Katherine started to think. She looked at the list of over 500 friends she had on Facebook and realized some of them were not really friends at all.

20. How did Katherine feel when her classmates added her as a Facebook friend?

解析：B。本题目为推理题。问题为： 当有人在 Facebook上加她的时候，Katherine感觉是怎样的？根据原文“At first this didn’t bother her, she love to learning about the success of people she knew when she was just a teenager.”，可见当她还是青少年时，她最初并没有产生烦恼，她喜欢了解别人取得的成功。故正确答案为B）She enjoyed reading her friends’ status updates（她喜欢阅读朋友发布的最新状态）。本题需要基于理解做出选择，联系语境，此处status update是指“在SNS上更新状态”。
