SECTION B PASSAGES
Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.
听力原文: As you know, there are too many students today who is trying to crack the puzzle of career success, do all the right things, like going to the right school, studying the right things and getting the right grades. To some extent, every student in this room is doing that.
I want you to promise yourself that, after tonight, you'll spend a little more time being selfish. Because if there isn't some "me" time in the equation, you won't be successful.
The other thing you have to do to succeed in meeting your career goals is to be prepared for a lifetime of learning. You could not think that your education is finished once you get your degree (or degrees), even if your degree is from a good school like the University of Minnesota.
This learning can involve formal training: participation in teams or task forces or new assignments. Companies today cannot be competitive in the global marketplace, unless all their people renew their old skills and develop new ones.
You need to be willing to leave your comfort zone. As Alvin Toffler said, "The illiterate of the future are not those who cannot read or write, but those who cannot learn, unlearn and relearn."
The speaker tells the students that they are not likely to succeed if they
A. are too selfish.
B. do everything as others do.
C. are not greedy enough.
D. don't get a right degree.
