Driving cars, trucks and motorcycles is
an important part of our lives. We do it every day to get to work, to school or
to friends’ houses. Driving can be very convenient, but can also cause many problems. Waiting in line at a red light, a driver may get impatient and decide just to drive right through it. If another car is coming from the other direction, there might be a terrible accident. Cutting another car off can make its driver angry, so that driver cuts off someone else. Pretty soon everybody is angry, and impatient. Traffic accidents declare millions of lives every year worldwide. In America alone, over seven people are killed in accidents every day.

{{B}}Old Man Myths and Realities{{/B}}
1. When does a middle-aged man become an old man Officially, of course, it’s when we reach retirement age. But, as we all know, this is a fairly blunt (生硬的) method of decision making. As life expectancy (预期寿命) increases, retirement planning needs to be changed. This is because being an old man today is very different from what it was a generation or so ago. 2. Sixty-five is the new middle-aged man. These days people are talking about the young-old, that is ages 70-75, and those over 75 as the old-old.
