听力原文：M: Is that a map？ Are you going sailing or something？

W: I wish. It's a hurricane-tracking chart. It's a map of tropical ocean areas southeast of us. It follows the development of tropical storms, even hurricanes. They develop and move around the Atlantic in the Caribbean and here on the Florida coast. We got hit a lot by those at least winds or rain in July or August.

M: Do you think that a tropical storm is on the way？

W: Too early to tell, but we need to be prepared. The radio mentioned possible evacuation routes.

M: Really？ It's that serious？

W: Youd better believe it. Late summer is hurricane season. The television updates locations and speeds every hour.

M: What did they say？ Is one out there now？

W: A couple of tropical depressions, two storms and two hurricanes.

M: What's the difference？

W: Wind velocity. A depression is the least serious actually, and a hurricane is the most serious.

M: How serious are the winds in hurricanes？

W: They have sustained winds of 74 mph and up.

M: What are the names on the map？ David, Arlene, Francisco, and Gina.

W: You know weather forecasters give the hurricanes names of people to make storms easy to identify.

M: I wonder what the status of the storm is now.

W: You shall turn on the television, and it has the best coverage. There is an up-date coming-up in five minutes.
