问题     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 suggeset 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.
The underlined words "a high" probably mean"______".
选项 A、a feeling of happiness
B、a reasonable thought
C、a great expectation
D、an exciting idea
答案A
解析 本题是推理题。根据常识，赌博赢以后会非常高兴，有些飘飘然，所以选A。high做名词可以意为“(吸毒引起的)快感，精神恍惚”。
