In the United States, 30 percent of the grown-up population has a “weight problem”．To many people, the cause is clear：we eat too much．But scientific experiments do little to support this idea．Going back to the America of 1910, we find that people were thinner than today, yet they ate more food．In those days people worked harder physically, walked more, used machines much less, and didn't watch television．
Several modern studies, besides, have shown that fatter people do not eat more on average (平均的) than thinner people．In fact, some research work, such as 1979 study of 3, 545 London office workers, reports that fat people eat less than thinner people on the average．
Studies show that thin people are more active than fat people．A study by the research group at Standford University School of Medicine found the following interesting fact． The more the man ran, the greater body fat he lost．The more he ran, the greater he needed for food．Thus, those who ran the most ate the most, yet lost the greatest amount (量) of body fat．
(1) What kind of physical problem do many grown-up Americans have?
[ ]
A．They are too thin．
B．They work too hard．
C．They are too fat．
D．They lose too much body fat．
(2) Based on the information given in this article, suppose there are 500 Americans, about how many of them will have a weight problem．
[ ]
A．30 B．50 C．100 D．150
(3) Are there scientific facts to support that eating too much is the cause of the “weight problem”?
[ ]
A．Yes, there are plenty of them．
B．Of course, there are facts to show this is true．
C．There are hardly any scientific facts to support this．
D．We don't know because the information is not given．

[ ]
A．ate more food and had more physical activities
B．ate less food but had more activities

Frank W． Woolworth was born in Rodman, New York, in 1852． His family was very poor farmers, and there was never enough to eat． Frank decided he did not want to be a farmer． He took a short business course, and went to work as a salesman in a large city．
Woolworth realized he had a natural skill for displaying goods to arouse people's interest, but he soon learned something more important． One day his boss told him to sell some odds and ends（小商品） for as much as he could get． Frank put all these things on one table with a sign which said：Five Cents Each． People fought and pushed to buy the things and the table was soon cleared．
Soon afterwards, Woolworth opened his own store, selling goods at five and ten cents． But he had another lesson to learn before he became successful． That is, if you want to make money by selling low price goods, you have to buy them in large quantities directly from the factories． Once, for example, Woolworth went to Germany and placed an order for knives． The order was so large that the factory had to keep running 24 hours a day for a whole year． In this way, the price of the knives was cut down by half．
By 1919, Woolworth had over 1,000 stores in the USA and Canada, and opened his first store in London． He made many millions and his name became famous throughout the world． He always ran his business according to strict rules, of which the most important one was：“The Customer（顾客）Is Always Right．”

How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in US.
For some parents the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as hazards and, with good guides, some education and a few precautions (预防措施), the wilds of the Internet can be safely navigated (航行). “Kids have to be on-line. If we tell our kids they can't have access (进入) to the Internet we're cutting them off from their future,” said an expert.
Most kids have started to learn to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. But the most popular that was to limit access would be to use what is known as a “content screener (过滤) ”. But this can't be wholly reliable, and the best thing parents can do is to talk to their kids and let them know what's OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing (浏览)the Internet.
A few other tips：
Don't put the PC in a child's room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity.
Ask your child what he or she has been doing and about any friends they make on-line.
Tell your child not to give on-line strangers personal information, especially details like address and phone number.
And tell your children never to talk to anyone they meet on-line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.
