1.B 2.A 3.C 4.C 【解析】 【原文】 Hello, there. Good afternoon! Thank you for your finding the time in your busy schedules to come to the international student office’s first meeting for students going abroad, to South America next autumn. By the way, if you haven’t already signed next to your name on our attendance lists - they’re on the table at the entrance to the school hall - be sure to do it on your way out. Remember, this meeting is a must for you, so you need to make sure we know that you’re here. All right, to begin, we’re going to be talking about health, and specifically the procedures that you have to go through in order to get your student visas for your host country. For all of you, this will include gathering health information, such as proof from your doctors that you’re not suffering from any serious diseases that may pass to others. All the information that each of you will need can be found in your host country handbook that you received when you were accepted into the program. Also, each one of you is required to meet with a doctor at the student health center who is specialized in travel medicine. The health center can give you information about appointment times, but be sure to book your appointment early, because the specialist is only at the health center at certain times. To have the benefit, you should have your meeting at least 4-6 weeks before your trip.
