A traffic jam The day I went to ChangSha to get study, I came across a traffic jam which made me unhappy. My parents and I were on the road to ChangSha then suddenly the cars were moving slower and slower and finally all of the cars were forced to stop. We had no idea about what happened at the first place. We had nothing to do but followed the cars in the front by steps. We were all feeling so boring just staying in the car. Eventually, we moved to the exits of this jam and finally knew the cause of this 2-hour-waiting jam is that the workers were fixing the road and had closed third of four of the road and resulted in the slow move of the cars. Fortunately, we only spent 2 hours on this traffic jam, some said they had spent 4 hours with nothing to do, but I still think this kind of traffic jam is avoidable, this little thing cost us not only time, but also energy.
