Task 1     Read the passage. Choose the best answer for each question. How to make the most of a career fair. If you get the opportunity to go to a career fair, you should make the most of it. Career fairs are a great way to speak to different employers. So, how can you take advantage of all that is on offer? The first thing you should do is to prepare yourself. Find out which organizations are going to be there and do your research. Make sure you know who you want to speak to and think about what you want to say. You should also prepare an up-to-date copy of your résumé to show to anyone who might be interested in your skills and experience. On the day of the career fair, you should make the right impression. You don’t have to wear your best suit, but dressing smartly will show that you are professional. If you think of the fair as an interview, then it’s more likely you’ll get one in future.  It’s a good idea to arrive early on the day of the career fair. This can mean you don’t have to stand in a long queue. However, staying around until the end of the fair means you may have the chance to speak to an employer one to one. Finally, don’t forget to follow up on any interesting people you meet at the fair. If you’ve spoken to an employer, try to connect with him / her online. Stay in touch with potential employers and they will be reminded of who you are and what you can offer.   What is the writer’s opinion of career fairs?
