Student A: Good morning! Could you explain what the expression "sign up for" means I found it on page 108, but I’m not sure.
Student B: Sure! "Sign up for" means to register for an activity or a course. For example, if you want to join the English club, you can sign up for it. By the way, I don’t know the meaning of "adapt to" on page 105. What does it mean
