Stratford –on-Avon , as we all know , has only one industry-William Shakespeare-but there are two clearly separate and different branches . There is the Royal Shakespeare Company (RSC), which presents excellent productions of the plays at the Shakespeare Memorial Theatre on the Avon . And there are townsfolk who largely live on the tourists who come , not to see the play , but to look at Anne Hathaway’s Cottage , Shakespeare’s birthplace and the other sights .

The townsfolk of Stratford doubt that the theatre adds a penny to their income . They frankly dislike the RSC actors , those who walk with Jong hair and beard and great noise .

The tourist stream are not entirely separate . The sightseers , who come by bus and often take in Warwick on the side , don’t usually see the plays . And some of them are even surprised to find a theatre in Stratford . However , the playgoers do manage a little sight-seeing along with their play-going . It is the playgoers , the RSC declares , who bring in much of the town’s income because they spend the night (some of them four or five nights ) pouring money into hotels and restaurants . The sightseers can take in everything and get out of town by nightfall .

The townsfolk don’t see it this way and local government does not put away some money for the RSC. Stratford cries poor traditionally . Nevertheless, every hotel in town seems to be adding a new wing or a cocktail room . Hilton is building its own hotel there , which you will be sure will be decorated with Hamburger bars , dinner rooms ad so forth , and will be very expensive .

Anyway ,the townsfolk can’t understand why the RSC needs help from the government . The theatre has broken attendance records for three years in a row . Last year , its 1,431 seats were 94 occupied all year long and this year they will do better . The reason , of course , is that costs have rocketed and ticket prices have stayed the same . It would be a shame to raise prices too much because it would drive away the young people who are Stratford’s most attractive customers . They come entirely for the plays , not the sights . They all seem to look alike , though they come from all over .

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 .
