Traffic jams（堵塞）is a big problem in many big cities. Now, people use a “super bus”to solve the problem. The“super bus”is 40 meters long and 6 meters wide. It has two floors. Passengers（乘客）sit on the upper floor. A“super bus”can hold 1,200 to 1,400 people. That is the work of about 40 ordinary（普通的）buses. When the“super bus”runs on the road, the other cars and buses can run through from its low floor. That is just like boatsor ships go through a bridge. So the“super bus”hardly（几乎不）takes any room of the roads. So we can say using the“super bus”is the best way to solve the traffic problem.
