And then, with a flick of its tail, the shark pushed itself backward into the water, and disappeared down the river.
Chet rose to his knees and threw up. When he could stand, he suddenly noticed his friends, Sid, Monty and Dewey, standing on the dock(码头). Before he could stop them, they had dived into the water.
