听力原文：W: Good afternoon, Mr. Green. I'm planning to go abroad for study. Do you think I

M: I think so. One unexpected medical emergency can drain your financial resources, leaving you with no money to pay for school. As a result, you'll have no choice but to return to your own country.

W: How can I get health insurance？

M: You really have two basic choices for health insurance: obtain international insurance in your home coma try before you depart or student health insurance once you arrive.

W: Then how to get international insurance？

M: As for international insurance, you'll have to pay the medical costs in full on your own. If you have sufficient funds, then this won't be a problem.

W: Oh, that seems not suitable for me. What about the second option？

M: As for the second option, you'll probably just have to pay a certain percentage, and the company will pay their part.

W: That sounds good. Then what should we note when signing the insurance agreement？

M: Well, be sure to clearly understand the terms of the agreement you sign with the insurance company. There are often a number of limitations and restrictions with the policy, and understanding them up will reduce the number of misunderstandings that could arise.

W: Oh, I see.

M: It is wise of you to consider health insurance before going abroad to study. However, many students only think about insurance when it is too late as they sit in the hospital's emergency room. So get insurance to help you pay for your medical expenses; otherwise, you might not have money for tomorrow's school tuition.

W: Well, I think I've got all the information I need. Thank you so much, Mr. Green.

M: You're welcome.
