英语课
Tea has complex compounds called polyphenols which are believed to help the arteries 1 to relax or dilate 2, thus enabling a smoother flow of blood.

Scientists tested black Darjeeling tea on 16 healthy women volunteers aged 3 more than 50.
科学家们对16位饮用了大吉岭红茶，年龄在50岁以上的健康女性志愿者做了测试。
When the women drank half a litre (0.9 of a pint) of tea, their arteries relaxed significantly more than when they drank hot water or tea with milk--tea in which skimmed milk, comprising 10 percent of the drink's volume, was added.
这些女性饮用了半升（0.9品脱）的茶，与饮用热水，奶茶的时候相比，她们的动脉得到了显著的放松。这里说的奶茶指掺有相当于饮料总体积10%的脱脂奶的茶。
The study points the finger of blame at three casein proteins in the milk. These are thought to adhere to a kind of polyphenols known as catechins, preventing them from carrying out their health-making work.
这项研究指出，影响茶发挥作用的罪魁祸首为牛奶中的三种酪蛋白。研究者认为它们会附着在一种叫儿茶酚的多酚上，使之无法发挥保健功效。
