Internet use appears to cause a decline in psychological well-being, according to re search at Carnegie Mellon University. Even people who spent just a few hours a week on the Internet (47) more depression and loneliness than those who logged on less frequently, the two-year study showed. And it wasn’’t that people who were already feeling (48) spent more time on the Internet, but that using the Net (49) appeared to cause the bad feelings. Researchers are puzzling over the results, which were completely (50) to their expectations. They expected that the Net would prove socially (51) than television, since the Net allows users to choose their information and to communicate with others. The fact that Internet use reduces time (52) for family and friends may account for the drop in well-being, researchers hypothesized. Faceless, bodiless "virtual" (53) may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that (54) to the wider world via the Net makes users less satisfied with their lives.

It was midnight in Paris and we were rolling toward Avenue Bosguet. As we came to the Pont Alexandra Ⅲ, the taxi slowed down, for the traffic light was red against us, and then, without stopping, we sailed through the red in a sudden burst of speed. The same performance was repeated at the Alma Bridge. As I paid the driver, I asked him why he had driven through two red lights.

“You ought to be ashamed of yourself, breaking the law and endangering your life that way.” I protested.

He looked at me, astonished, “Ashamed of myself? I am a law abiding(守法的) citizen and have no desire to get killed either.” He cut me off before I could protest.

“No, just listen to me before you complain. What did I do? Went through a red light. Well, did you ever stop to consider what a red light is? What it means?”

“Certainly,”I replied. “It’s a stop signal and means the traffic is rolling in the opposite direction.”

“Half-right,”said the driver, “But incomplete. It’s only an automatic(自动的) stop signal. And it does not mean that there is cross traffic. Did you see any cross traffic during our trip? Of course not. I slowed down at the light, looked carefully to the right and to the left. Not another car on the street at this hour. Well, then! What would you have me do? Should I stop like a stupid animal because an automatic, brainless machine turns red every forty seconds? No, sir,”he shouted, “I am a man, not a machine. I have eyes and a brain and judgment, given me by God. Ashamed of myself, you say? I would only be ashamed of myself if I let those blinking lamps do my thinking for me. Good night,sir.”
