听力原文： A survey carried out in eight countries found that people around the world are annoyed with guilt about the small pleasures in life. This doesn't stop people from indulging in alcohol, cigarettes and high-fat foods, but it does stop them from enjoying them. The survey questioned 4000 people about their attitudes towards a list of indulgences including smoking, eating chocolate and cakes, drinking alcohol and failing to exercise. It found that Australians are the world's most guilt-dominated people, while the Dutch were the greatest pleasure-takers and also least regretful about their indulgences. Germans came second in the guilt league and were least likely to take enjoyment from physical pleasures. Scientists said moderate indulgence reduces stress, a benefit that can be completely outweighed by feelings of guilt. A favorite treat, such as a cup of tea or coffee, a glass of wine or beer, a cigarette or a bar of chocolate reduces stress and helps people relax. But when people get caught in the guilt trap, they either try to sacrifice their enjoyment or live with the guilt. This can undermine the positive benefits of enjoyment which studies show can protect against stress and strengthen the immune system. At its worst, stress can lead to depression and illness such as heart disease and cancer. (33)
