A lot of people died(死亡) when they were having in the water, and most of them were students. Last summer, a few students went to swim in the river near their school. Unluckily(不幸地), three of them came out of the river.

Some people are not enough(足够的) when swimming. They often think they can swim well, and they may be in water. But some die because of carelessness(粗心).
