一、汉译英：
自由心灵，简单人生
2004年12月3日深夜，我正在网上游走，突然看到“陈省身”几个字从眼前倏然闪过……我把两年前采访陈先生时的合影找了出来，放在书架的正中间。在我和陈先生背后的墙上，是一只圆形的石英钟，上面的时针清楚地表明了那个瞬间：2002年4月5日13时13分零4秒。
那天的雨从睡梦中就下起来，到中午了还在哗啦啦下个不停。天地间白茫茫一片，街道，车辆，树木，路旁的建筑，撑开了的伞，全都湿漉漉的，显然洗去了不少市面上的喧嚣与浮躁，以及与浮躁同样轻飘飘的漫漫扬絮。
从天津西站到南开大学大约要走二三十分钟，出租司机是一位长相粗犷神色生动的中年人，高喉咙大嗓门，非常热情，一路上用他那地道的天津腔跟我们说话。我们跟他说起陈先生，他立马接过话说，陈省身？知道。大数学家，不得了！天津人懂点儿事的谁不知道啊！你要说这陈省身，那可是人才哪。司机一边骄傲着，一边还要左顾右盼，忙着找路旁哪儿有花店，以方便我们给陈先生买鲜花。
到了陈先生家，甫一坐定，陈先生就颇有些出其不意地说，你们今天应该向我道喜。看到我们面露疑惑，陈先生停顿了一下才解释说，以前患有静脉血栓，前些时候还住了两个来月的医院。今天上午刚又去查了，一看，血栓竟然没了。我们听明白后，忙说这倒真是件喜事，好消息。陈先生如小孩儿一般得意，连连说，是，好消息，好消息。

When Sports Drinks Kill
For years now, we have been hearing the importance of hydration to avoid heat stroke during prolonged exercise in hot weather. Now, it turns out, too much hydration can kill you.
A study published in The New England Journal of Medicine should give people reason to rethink the wisdom of quaffing vast amount or water or sports drinks while exercising vigorously—at least if they are engaging in such endurance tests as a marathon. The study found that a marathon runner could dangerously dilute the blood with an overdose of liquids, risking a coma and even death. The problem has also been detected during long military maneuvers, extended bike rides and blistering hikes through the desert.
An article in The New York Times describes the slow and belated recognition of the problem. A South African expert who has been warning of the dangers for more than two decades said that he had not found a single case in which an athlete had died from dehydration in a competitive race, but that several people had sickened and died from drinking too much.
All too often, friends, coaches or emergency personnel assume that the problem is dehydration and administer yet more liquid, making the problem worse. The best treatment is a small amount of concentrated salt solution, given intravenously, to increase blood sodium concentrations. Sports drinks containing electrolytes may not help much as they are mostly liquid themselves.
In the 2006 Boston Marathon, for example, a 28-old woman found herself exhausted after running for five hours and gulping sports drinks along the way. Wrongly assuming that she was dehydrated, she chugged down a sports drink. She promptly collapsed and was later declared brain-dead. The concentration of salt in her blood was found to be lethally low.
Sports authorities have already issued warnings and tips to avoid excessive drinking. The solution is for overly eager endurance runners and hikers to forget the old mantra that they should drink—drink—drink. Too much liquid can be lethal.
