(B) If the discipline of linguistics has so little to be said in its favour, one might wonder how it continues to flourish as widely as it does. It was never the case that all universities contained a linguistics department, and there are probably fewer of them today than there were in the immediate aftermath of the 1960s wave of enthusiasm. But the many linguistics departments that still exist are fairly secure. In the 21st century, decisions about which subjects should be offered in a university are made not in terms of their intellectual solidity but of which will be cost-effective, by attracting a market of student takers. Linguistics departments are well placed there, for two reasons. (Sampson, Geoffrey. 2017. The Linguistics Delusion, Equinox)

Question Question What does "you are at a new stage in your life" mean? How many pieces of advice does the writer have for you? ¹ Welcome aboard! You are now at a new stage in your life. What do you want to do? Many of you may not be able to answer this question easily. Some may reply, “I have no idea.” 2) Do not take the question too seriously. Start with something familiar. For example, you can try to “make a lot of new friends,” “become a regular player on your sports team,” “learn how to play the guitar,” or “learn five new English words a day.” 3) You see? You can find many things to do. You may say that you do not know how to achieve these things. Well, if that is the case, here are four pieces of advice for you.
