①A new study provides more good news for coffee lovers.②Drinking coffee is associated with a lower risk of early death — virtually regardless of how much you drink and whether or not it’s caffeinated, _______ a paper published Monday in JAMA Internal Medicine. ③That finding, combined with the apparent longevity-boosting effect of decaf coffee, suggests that caffeine isn’t the life-lengthening mechanism at work in java, Loftfield said. ④But because the current study was observational, meaning it looked only at patterns in an existing dataset, it’s impossible to say what is — or even if coffee is truly responsible for keeping death at bay, or just associated with a longer life.

【参考译文】

①A new study p rovides more good news for coffee lovers. 一项新的研究为咖啡爱好者带来了更多的好消息。

②Drinking coffee is associated with a lower risk of early death — virtually regardless of how much you drink and whether or not it’s caffeinated, concludes a paper published Monday in JAMA Internal Medicine. 周一发表在《美国医学会杂志·内科学》上的一篇论文结论说，喝咖啡可以降低早逝的风险——事实上，不管你喝多少，也不管是否含有咖啡因。

③That finding, combined with the apparent longevity-boosting effect of decaf coffee, suggests that caffeine isn’t the life-lengthening mechanism at work in java, Loftfield said. Loftfield说，这一发现和去咖啡因咖啡的延长寿命的明显作用表明，咖啡因并不是在爪哇发挥作用的延长寿命的机制。

④But because the current study was observational, meaning it looked only at patterns in an existing dataset, it’s impossible to say what is — or even if coffee is truly responsible for keeping death at bay, or just associated with a longer life. 但由于目前的研究是观察性的（这意味着研究只审视了现有数据集的模式），所以我们不可能说究竟什么是延长寿命的机制 —— 或者即使咖啡真的起到阻止死亡的作用，或者仅仅与长寿有关。
