听力原文： So, if there are no more questions about the facilities at student services or any of the special activities we have talked about, then we can move on to the next topic.
The last topic is health insurance. You will be required to have a health insurance policy of some sort at registration. If you are a scholarship student, you probably have automatic coverage established. If you are paying for your own tuition, you can still get insurance through the school. The forms to buy insurance from the school will be available at the registration desk when you register. If you have any questions about the benefits available, you can look at the back of the student handbook. In general, the school usually offers a good insurance policy compared to private companies so you should take a look. If you are receiving financial aid, you should contact your financial aid counselor to see if you can also receive insurance coverage.
If there are no other questions, that will do it for today .The best advice is to follow your student handbook and things should go smoothly. Remember, if there are any problems, you can ask me or any of the other student helpers. We will be under the sign that says "registrar's" at the registration area.
