单选题______ those bad habits, he would not have got liver cancer.

单选题The research was done by a Dr. Griffiths in England. He compared the behavior of 15 regular gamblers (赌徒) with those of 15 non regular gamblers before and after they gambled. Both groups had increased heart rates (心率) during gambling because it was exciting. But the regular gamblers' heart rates went down almost straight after the game, while the non regulars remained excited and had increased heart rates for longer. When the heart beat increases, the body produces chemicals called endorphins which make you feel good. Dr. Griffiths thinks that regular gamblers lose this good feeling soon after a game and need to play again quickly to regain the pleasure. He has also discovered that regular gamblers have different psychological reactions (心理反应) from non regular gamblers. In an experiment where regular and non regular gamblers thought aloud while playing, regular gamblers had far more unreasonable thoughts. In their minds they turned losses into near wins. Dr. Griffiths thinks that nearly winning gives the gambler a high in the same way that a win would do. Based on Dr. Griffiths' research, doctors suggest that one way to help regular gamblers to give up gambling is to give them beta blockers -- drugs that stop them getting a high in the first place.

Mum pointed to a big chair by the door and I knew she wanted me to have a seat. While I watched, mouth open in surprise, mum took off her hat and coat and gave them to me to hold. She walked quietly to the small room by the lift and took out a wet mop (拖把). She pushed the mop past the desk and as the nurse looked up, mum nodded and said, "Very dirty floors." "Yes. I'm glad they've finally decided to clean them,"the nurse said. She looked at mum strangely and said, "But aren't you working late?" Mum just pushed harder, each swipe (拖) of the mop taking her farther and farther down the hall. I watched until I couldn't see her and the nurse had turned back to write in the big book. After a long time mum came back. Her eyes were shining. She rapidly put the mop back and took my hand. As we turned to go out of the door, mum nodded politely to the nurse and said, "Thank you." Outside, mum told me: "Dagmar is fine. No fever." "You saw her, mum?" "Of course. I told her about the hospital rules, and she will not expect us until tomorrow. Dad will stop worrying as well. It's a fine hospital. But such floors! A mop is no good. You need a brush."

单选题{{B}}D{{/B}} On Oct. 12, 1989, some Chinese scientists were working at the computers to look for the in- formation they needed. Suddenly they saw a lot of very bright spots crossing the computer's screens. At the same moment the computers were working much slower. To find out what was happening, they stopped their work to check some parts of the computers. To their horror, they found out that most of their stored information was got rid of by computer viruses (病毒). All these computers had been infected by computer viruses. It is said that the computer viruses were made by a group of young men fond of playing tricks. They all have excellent education. They created the viruses just to show their intelligence. These kinds of computer viruses are named Jerusalem Viruses. These viruses can stay in computers for a long time. When the time comes they will attack the computers by lowering the functions, damaging normal programs or even getting rid of all the information. We now come to know that Jerusalem Viruses often attack computers on Fridays and that they are spreading to a lot of computers. Among the countries that suffered computer viruses last year are Britain, Australia, Switzerland and the U. S.. But till now, how to get rid of the terrible viruses remains a problem.
