If you’re training for a marathon , a proper plan for water intake (摄入) is important . Of course , there’s the risk of dehydration (脱水) . But athletes now know they can also get into trouble by drinking to much . To much water intake can lower levels of sodium (钠) in the blood . The death of a 28-year-old woman following the Boston Marathon caught the attention of many runners and led to new research .

Experts advise long distance runners to replace the liquids they sweat out . Their goal is to try to keep someone from not getting dehydrated by more than 2 percent of their body weight .

One technique for deciding how much water you need is to get the exact numbers . Runners have to weight themselves before and after a run to determine how much water they’ve lost . If their weight drops by more than 2 percent , they have not drunk enough water.

Hyponatremia occurs when runners drink so much water that blood salt levels drop off . A study published last year tested 488 runners who completed the Boston Marathon and found 13 percent of them had dangerously low blood salt levels . The first sign that runners may notice is slightly swelling in the hands . They can’t get their rings off , and then they might feel sick . They may not remember where they are . In fact , most runners get enough salt to get back to normal levels by eating just one meal after a run . Contrary to the old advice that runners should drink as much as they can to prevent dehydration , the new research has shown that the body is a remarkable machine that actually tells you via thirst when you need water .

It cam as something of a surprise when Diana , Princess of Wales , made a trip to Angola in 1997, to support the Red Cross campaign for a total ban on anti-personnel landmines (地雷). Within hours of arriving in　 Angola , television screens around the world were filled with images of her comforting victims (受害者) injured in accidents caused by landmines . “I knew the huge numbers ,” she said . “But putting a face to those figures brought the reality home to me ; like when I met Sandra , a 13-year-old girl who had lost her leg , and people like her .” The Princess concluded with a simple message : “We must stop landmines”. And she used every opportunity during her visit to repeat this message .

But , back in London , her views wee not shared by some members of the British government , which refused to support a ban on these weapons . Angry politicians started an attack on the Princess in the press ，They described her as “very ill-informed” . The Princess responded by brushing aside the criticisms: “This is a prevention we do not need . All I’m trying to do is to help.” Opposition parties , the media and the public immediately voiced their support for the Princess . To make matters worse for the government , it soon appeared that the Princess trip bad been approved by the Foreign Office , and that she was in fact very well-informed about both the situation in Angola and the British government’s policy regarding land nines . the result was a sever blow on the government .

To try and limit the damage , the Foreign Secretary　 Malcolm Rifkidnd , said that the Princess’ views on landmines were not very different from the government’s policy , and that it was “working towards” a worldwide ban . The defense secretary , Michael Portillo declared the matter was “a misunderstanding”. For the Princess , the trip to this war-torn country was an excellent opportunity to use her popularity to show the world hw much destruction and suffering landmines can cause . She said that the experience had also given her the chance to get closer to people and their problems .
