1 Coffee is one of the world's most widely-enjoyed beverages. Flavor aside, scientists have recognized it as a complex blend of chemical compounds with potential health effects, both good and bad. Now, new research suggests that if you drink enough coffee, it might help you avoid certain kinds of cancer.
咖啡是世界上最受人喜爱的饮料之一。姑且不论它的味道，科学家们已经知道咖啡里含有多种对健康具有潜在影响的化学成分，其中有好的、也有坏的影响。一项新的研究指出，如果你饮用足够量的咖啡，可能有助于避免某些癌症。
2 Dr. Mia Hashibe of the University of Utah School of Medicine was interested in the link between coffee drinking and certain cancers of the head and neck. Researchers have looked into this before, but without reaching any firm conclusions. 犹他大学医学院的米亚•哈希贝医生对咖啡以及某些头部和颈部癌症之间的关连非常感兴趣。研究人员过去也曾经对此进行过探讨，可是没有提出任何肯定的结论。
3 "There were a few studies, but the findings were not consistent across the studies," she said, "so this finding from our current study was quite a surprise. We didn't really have any expectation of which direction it could go into." 她说：“有过一些研究，但并没有得出一致的结论。所以，我们目前研究中的发现，确实令人感到惊喜。我们事先并没有指望这项研究会朝哪个方向发展。”
4 To sort out the confusion, Hashibe and her colleagues used statistical techniques to, in effect, make one big study out of the previous smaller studies. 为了解决这些困惑，哈希贝医生和她的同事们利用统计学，综合过去各种小范围的研究结果，完成了一项大型研究。
