About 70000000 Americans are trying to lose weight(减肥)．That is almost l out of every 3 people in the United States．Some people eat 1 food and they hardly have any fats or sweets．Others do running，exercise with machines，take medicines，or even have operations． 2 you can see losing weight is a 3 work. Why do so many people in the United States want to lose weight？
Many people in the United States worry about their look of the body．For many people，looking nice also means to be 4 ．Other people worry about their health as many doctors say over weight is not good．
Most people want to find a faster and 5 way to take off fat，and books of this kind are very popular. These books tell people how to lose weight．Each year a lot of new books like these are 6 ．Each one says it can easily help people take fat away．
Losing weight can be 7 ．Some overweight people go to health centers，like La Costa in California．Men and women pay several hundred dollars a day at these health centers．People live there for one week or two，taking exercises eating different foods．Meals there may be just a little．All this works for losing weight． 8 4 days on the programme，one woman called Mrs．Warren lost 5 pounds(2.27kg)．At $ 400 a day，she spent $ 320 to lose each pound．But she said she was still 9 to do so．
Health centers，books，medicines，operations，running and exercise machines all need a lot of money．So in the United States，losing weight may mean losing 10 too．
In the West, some people believe that personality can be predicted according to the time of the year the person was bor．From China comes the belief that the year of birth influences one's personality．In the past century, a new belief ahs arisen：the idea that personality is related to one's ABO blood type．People with blood type A, for example, are considered more likely to be serious, hard-working, and quiet, while people with blood type O are likely to be popular and outgoing, yet often unable to finish what they start．Though this belief continues to be strong, some people question whether it is true．
The blood-type personality theory(理论)started in Japan in 1927 when Furukawa Takehi noticed personality similarities and differences among his workers．This idea soon went out of fashion, but was brought back by a Japanese television host named Toshitaka Nomi in the 1970s．The belief is still strong in Japan and is increasingly popular in neighboring countries．Some young Koreans have taken to the theory．A recent study showed 76 percent of Koreans aged between13 and 64 believing in the blood-type personality connection．Though most Asians might believe in the blood-type theory, for many it seems harmless and not something to be taken too seriously．
Is the belief true?The scientists in Asia largely dismiss the belief as a modern-day superstition(迷信)．Most studies have failed to find any strong connection between blood and personality．Generally, scientists warn against making predictions or important decisions based on this questionable theory．
