(Đọc ý kiến của những học sinh này về thiên tai và thực hiện các nhiệm vụ tiếp theo.)

Ann: There are far more natural disasters today than in the past. Every time I switch on the news, I see floods or areas destroyed by earthquakes. Natural disasters are really scary because they can cause a lot of damage to humans and their property. I believe human activities are directly related to all disasters.

Nick: Some natural disasters are predictable, but some are not. Yesterday, I read about a hurricane which caused flooding in a large area. The flood occurred suddenly when people were sleeping, so many of them were not prepared and were trapped in their flooded homes. I think we should spend more money to develop warning systems for hurricanes, floods, and other disasters.
