Whenever you buy something, it is possible that someone has already worn, eaten, or tested
it to make sure it is safe and do what is supposed to do. But what if you wanted a special suit to keep a shark from hurting you? Who wants to test a product like it?
"I do! " says Jeremiah Sullwan, a scientist in California "You have to believe in what you sell, right?"
Sullivan. owns SharkArmor Tech, a company that makes a $ 49400 sharksuit that even a great white shark can’ t bite through. Before Sullivan could sell his sharksuits, he needed to make sure his design would work. Sullivan put on the sharksuit and jumped into a shark feeding ground. "I need to know exactly what a human body could expect to go through," he says. Sharks moved all around him and then attacked his arm. Sullivan felt the bite but no teeth. He was uncomfortable at times, but not painful. The suit works! "
"I’ve now been bitten thousands of times but. never badly," says Sullivan, who now works with shows like Wild Kingdom, and programs for the Discovery Channel’s Shark Week.
So,are you all set to buy a sharksuit? Before you do, you should know that the suit weighs 20 pounds and makes swimming almost impossible--not so practical for a day on the beach. And in fact, Sullivan wants only professionals, such as filmmakers, scientists and drivers, to have sharksuits. Why? Because even if someone is wearing a sharksuit, they could get seriously hurt if they treat diving with a 4,OOO-pound shark as a game.
During sharksuit testing, sharks have thrown Sullivan to a bottom o/ reefs(礁) and tried to take him off into the deepest part of the ocean. "However," Sullivan says," you don't need to be afraid of sharks. It’s actually pretty hard to get a shark to bite you, "

Most children now chat daily either online or through their mobile phones. They are connecting to a huge number of other children all over the world. Some are shy “in real life” but are confident to communicate with others online; others find support from people of their own age on relationship issues, or problems at home.
Sometimes the online world, just like the real world, can introduce problems, such as arguments. Going online is great fun, but there are also a few people who use the Internet for offensive (冒犯性的) or illegal aims. Children must be made aware of both the good things and the dangers.
To keep children safe your management must cover the family computer. Just as you decide which TV pro-grams are suitable, you need to do the same for the websites and chat rooms your children visit. Remind your children that online friends are still strangers. Re-minding them of the risks will keep them alert (警惕).
Computer studies are part of schoolwork now, so it’s likely that your children may know more than you do. We get left behind when it comes to the latest gad-gets and the interactive areas of websites, like chat rooms and message boards, which are especially strange. The language of chat is strange to many parents, too. Chatters love to use abbreviations (缩写) such as: atb — all the best, bbfn — bye bye for now, cul8er — see you later, gr8 — great, Idk — I don’t know, imbl — it must be love, kit — keep in touch, paw — parents are watching, lol — laugh out loud, xlnt — excellent!The passage is meant for ______.

Most people think their time problems are outer, and that they are caused by the telephone, meetings, visitors, and delayed information or decisions. Although these problems often have a bad effete on them, as when people call or drop in, we usually contribute to them. We fail to have calls screened by a skillful secretary or assistant, or we leave our door open, actually assuring constant interruptions.
In almost all cases, it is possible to influence, if not control, it usually can cause problems, such as, slowness and indecision, lack of self-discipline, the inability to delegate, or the tendency to fight fires, to act without thinking, and to jump from task to task without finishing any of them.
Time is constant that cannot be changed. The clock cannot be slowed down or speeded up. Thus we cannot manage time itself. We can only manage our activities with respect to time.
The same skills are needed as those used in managing others—the abilities to plan, organize, delegate, direct, and control. Time management is simply self-management. It is impossible to be effective in any position without controlling one’s time effectively.
Successful time management does not mean working harder, but working smarter. All kinds of management skills must be used in the home and office to get most value from time. You must think ahead about what to do, and timely than others, making it get maximum results in the shortest possible period.According to the writer, time problems .

In the early part of the twentieth century, racism was widespread in the United States. Many African Americans were not given equal opportunities in education or employment. Marian Anderson (1897-1993) was an African American woman who gained fame as a concert singer in this climate of racism. She was born in Philadelphia and sang in church choirs during her childhood. When she applied for admission to a local music school in 1917, she was turned down because she was black. Unable to attend music school, she began her career as a singer for church gatherings. In 1929, she went to Europe to study voice and spent several years performing there. Her voice was widely praised throughout Europe. Then she returned to the US in 1935 and became a top concert singer after performing at Town Hall in New York City.

All over the world, and for many different reasons, there are millions of people who rarely or never eat meat. These people are called vegetarians. To people who eat meat, being a vegetarian may seem like a very strange thing, diets for several different reasons.
First, vegetarians have an enormous health advantage. One of the major health problems in modern societies is not too much protein but too much fat, especially in the form of animal fats. Medical evidence suggests that animal fats, including butter, contribute to the development of cholesterol in the human body. High amount of cholesterol seem to be part of the cause of heart disease. Most vegetarians have low level of cholesterol. High amounts of animal fats also seem to lead to certain kinds of cancer, and vegetarians are typically less vulnerable to these cancers than people who eat a lot of meat. Overall, studies comparing the health of vegetarians and meat-eaters show that the meat-eaters are twice as likely to die of heart disease as vegetarians are.
Better health is one reason that people choose to become vegetarians. Another reason is religion. Some religions forbid the eating of meat. The largest of these is the Hindu religion, which has about 600 million believers in the world. Although not all Hindus are vegetarian, many are, and there are many believers of other religions such Buddhism and even some Christian religions that also do not eat meat.
Many vegetarians do not eat meat simply because they do not like the taste of it. They have no religious or philosophical reasons; they just do not like meat. Another important reason that vegetarians give for not eating meat is the health advantages that were given above.
