23、 As is obviously seen in the picture, traffic jam is a big problem. 50 people want to go out, they have two ways to be chosen from, driving 50 cars or taking a bus. Which way is more convenient? People show great concerns about it.

 Nowadays, with people becoming richer and richer, they can afford to buy whatever they want, including cars, thus causing over-crowded roads and many traffic jams. On the other hand, that some roads have not been designed reasonably is another important reason.

 As far as I am concerned, the general public should take a bus more often when they want to go out. Only in this way can we prevent traffic jam.
