It's known to us that some university students were drowned because they wanted to rescue the boy who fell into the river . They quickly formed a man-bridge . But to their suprise ,one of them was so tired that he put out his hand . As a result ,five students were drowned . They had lost the precious lives . Why were they so careless ? It was very silly that they went to rescue the boy without paying attention to that they didn't have swim skills . As university students ,they don't know how to protect themselves . This is must be a big problem . So we should take our strength to rescue others without hurt ourselves .
