In high school I wanted to be an electrical engineer and, of course, any sensible student with my aims would have chosen a college with a large engineering department, famous reputation and lots of good labs and research equipment. But that’s not what I did. I chose to study engineering at a small liberal-artsuniversity that doesn’t even offer a major in electrical engineering. Obviously, this was not a practical choice; I came here for more noble reasons. I wanted a broad education that would provide me with flexibility and a value system to guide me in my career. I wanted to open my eyes and expand my vision by interacting with people who weren’t studying science or engineering. My parents, teachers and other adults praised me for such a sensible choice. They told me I was wise and mature beyond my 18 years, and I believed them. I headed off to college sure I was going to have an advantage over those students who went to big engineering “factories where they didn’t care if you have values or were flexible. I was going to be a complete engineer: technical genius and sensitive humanistall in one. Now I’m not so sure. Somewhere along the way my noble ideals crashed into reality, as all noble ideals eventually do. After three years of struggling to balance math, physics and engineering courses with liberal-arts courses, I have learned there are reasons why few engineering students try to reconcileengineering with liberal-arts courses in college. The reality that has blocked my path to become the typical successful student is that engineering and the liberal arts simply don’t’ mix as easily as I assumed in high school. Individually they shape a person in very different ways; together they threaten to confuse. The struggle to reconcile the two fields of study is difficult.

Some people don't believe that driving more slowly can save lives．But the truth is that driving more slowly can help a person to avoid serious accidents．

The following chart shows the distance that it takes to stop a car at a given speed．The distance is measured in feet．The shaded area shows the driver's thinking distance．That's the distance it takes for the driver to react to a danger that he sees．The white area shows the car's braking distance．That's the distance it takes for the car to stop once the brakes（闸、刹车） are used．The number at the top of each bar shows the total number of feet that it takes to stop the car

1．According to the chart, what is the total number of feet needed to stop a car that is traveling at 50 miles per hour?

A．55． B．73． C．128． D．183．

2．What is the braking distance for a car that is traveling at 60 miles per hour?

A．66 feet． B．119 feet． C．185 feet． D．251 feet．

3．Which of the following statements about braking and speed is true?

A．The braking distance is what it takes for the driver to react to a danger that he sees．

B．The speed of a car has a direct effect on the distance needed to stop the car．

C．The braking distance increases only when a driver drives faster than 50 miles per hour

D．Driving slowly can help a person to avoid all accidents
