【推荐3】How to Survive Being Stuck in a Lift

Being stuck in a lift, also known as an elevator, can sometimes be scary, especially if you are a fan of those kinds of movies which have a lot of elevator tragedies. You may think being stuck in an elevator in real life is not like in the movies.    1    

Remain calm and do not panic! You may have heard of this a lot of times and it is true that panicking will do you no good.     2    

Press each of the floor buttons one by one. Then, try the “doors open” button. If none of the buttons works, the lift is broken, and you need to let someone know about it.

See if your phone has any reception or Internet.     3     If you have WiFi connection, contact a family member or friend. Don’t forget to tell them what the address is of the building and possibly which elevator you are stuck in. If your phone is not available, the following tips can help you.

Look through the gap between the doors of the lift. If you can see light between the doors, the lift has stopped near a floor, and you should be able to shout for help and be released. Do not try to force the doors open yourself. If you can’t see light between the doors, the lift has stopped between floors, and no one will be able to let you out if you scream for help. Look for an emergency telephone. If there is no telephone, press the alarm button repeatedly.     4    

    5    If you have waited for more than half an hour and nobody has come to get you out, shout and bang the inside walls of the lift. If no one is responding to you, then you’ll have to accept that you will be in the lift overnight. If this happens, make yourself as comfortable as possible to save your energy. By morning, the building should be full again. You can try to get some help then.

A．It will cause you not to be able to think clearly.

B．Check the time.

C．Eventually, someone should hear you and get help.

D．Here are some tips to help you survive.

E．However, it is still a vital thing to know how to survive if it ever happens to you.

Americans spend more than $1 billion a year on calcium supplements (补充剂) in hopes of delaying osteoporosis, the brittle bone disease that cripples many elderly women and some men. Yet recent studies link calcium supplements to a higher risk of heart attacks. Last month, the U. S. Preventive Services Task Force issued a draft recommendation against taking calcium and vitamin D, saying there wasn’t enough evidence of benefit to justify the risk.

For generations of Americans who grew up encouraged to drink milk to maintain strong bones, the reports raised troubling questions: Is calcium not so important after all? Are the supplements unsafe? And how much is too much? “It’s gotten very confusing but it doesn’t need to be,” says Ethel Siris, director of the Toni Stabile Osteoporosis Center in New York. How much calcium people need varies by age and gender. “Adults generally need 1,000 mg daily, rising to 1,200 mg for women over 50 and men over 70, according to guidelines issued in 2010. Children need 1,300 mg daily during the peak growing years of 9 to 18. ”

People also need sufficient levels of vitamin D to absorb the calcium. The IOM recommends 600 international units a day for most adults, and 800 daily after age 70, although many physicians recommend more. It is difficult to take in that much vitamin D from food sources, so experts say many people should take vitamin D in supplement form.

Getting adequate (充足的) calcium from food is easier. For example, 8 ounces of milk or 6 ounces of yogurt has 300 mg of calcium, and one cup of spinach has 270 mg.

But studies linking calcium supplements to heart attack have made experts more cautious of excess calcium than before. A study of 24,000 Germans published in the journal Heart last month, found that those who got their calcium exclusively from supplements were more than twice as likely to have a heart attack as those who took no supplements.

Exactly how calcium supplements might contribute to heart attacks baffles cardiologists (心脏病学家). “Nobody has associated the calcium in your bloodstream with calcification (钙化) in your arteries,” says Nieca Goldberg, medical director of the Joan H. Tisch Center. Still, she says she now urges patients get their recommended calcium from food than from supplements to avoid possible problems.

Osteoporosis experts also urge patients not to take more than the recommended amount of calcium. “People should definitely stop taking two big calcium supplements a day,” says Dr. Dawson-Hughes. Even if the risks remain unclear, taking more than the body can absorb doesn’t benefit bones, “so it’s not worth any risk. ” She adds.

This can lead to many problems, and music companies are now cracking down on this practice. Sharing music online without permission is theft.

Sharing music online prevents recording companies from making money from their efforts. They say that sharing music online has resulted in a huge drop in profits and sales over the past 10 years. People who find music for free online are not paying for CDs or every piece of music downloaded. To truly understand the influence of music piracy (盗版行为) on creators, one must understand how many people are involved in the recording process. For the sale of each album, profits must be shared among musicians, sound engineers, music producers, managers, advertisers, and the company selling the product. Many people believe sharing music only affects the recording artist, but the reality is that sharing hurts business for all companies involved.

There are many people who don’t see the harm in sharing music online and even think they have the right to do it. One online blogger states that he originally paid for an entire CD and that he should be able to do with the material whatever he wants. While he may have legally paid for the music, he does not have the right to share it without permission, which means people like the blogger are thieves.

Although we don’t spread music the same way we did before, there’s no doubt that people around the world love to share music. However, Internet piracy will prevent musicians from continuing producing albums for fear of theft. Therefore, if people want to continue listening to their favorite artists, they need to buy their music so that artists will make enough profits to continue their music careers.
