W: Your parents aren't coming back soon, are they?
M: Yeah well, they e-mailed me the other day and they seem to be staying in Poland, at least for the time being. I just don't know when they will change their idea.
Q: What does the man mean?
正確答案：C
解析：男士說父母發電子郵件說他們要待在波蘭。故答案是C。選項都是關于His parents的描述，而且都含有時間狀語，猜測題目與他父母去留某地的時間有關。強干擾項D中的“settle down”屬于過度推測，從對話原文中并不能判斷出“父母”是否要在波蘭“定居”。

W: You told me you liked your job. Why do you look so upset?
M: Whenever we try to change the work routine, the workers have so many ifs and buts that we never manage to change anything.
Q: What does the man mean?
正確答案：B
解析：女士問男士為何不高興，男士說不管怎樣嘗試去改變工作程序，工人們總是有許多借口去反對，結果什么都改不了。故答案是B。選項都是workers發出的動作，猜測題目與工人們的行為有關。ifs and buts指的是不愿意做某事的借口或反對的理由。
