七选五

For centuries Antarctica has attracted people from around the world. Explorers sought to travel there. Scientists have studied weather, wildlife, and geology there for decades.  In the last few decades, though, scientists have reported that the ice is melting.

  That's a difficult question to answer. The loss of ice in Antarctica has not been linear (直线的). That means it isn't a steady decrease. In fact, the rate of melting can vary greatly from year to year. Still, scientists warn that the continent's ice sheet is shrinking.

 Climate change is warming the world's oceans and affecting the currents (洋流) of the Earth's oceans. These currents are bringing more warm water to Antarctica than ever recorded.

Today, the planet is warming at a rate that alarms scientists.  The effects of such a rise could cause major problems. It will increase flooding, especially in areas near shores. A large rise in sea level could even make some regions uninhabitable. This could cause millions around the world to become climate refugees (难民).

Can humans stop Antarctica from melting? Probably not — but experts do believe people can slow the process. How can you help? Pay attention to your carbon footprint.  Only changes on a large, global scale (范围) can truly make a difference to Antarctica.

A. How quickly is Antarctica melting?

B. Is human activity contributing to the melting of Antarctica's ice?

C. The ice of Antarctica is the result of thousands of years of snow.

D. West Antarctica is the region most affected by these warm waters.

E. Talk with your family about ways to reduce your use of fossil fuels.

F. If this continues, melting ice could lead to a serious rise in sea level.

G. Experts say the melting of Antarctica's ice sheet is caused by rising temperatures.

      What do the world's most successful people all have in common?

      By examining the work habits of over 150 greatest writers and artists and scientists, the researchers includingStandford Professor Jeffrey Pfeffer found that high achievers like Robert Mosesturn out to be all alike:

Busy ! Busy!

{#blank#}1{#/blank#}In a study of general managers in industry, JohnKotter reported that many of them worked 60 to 65 hours per  week—whichtranslates into at least six 10-hour days. The ability and willingness to workdifficult and tiring hours has characterized many powerful figures. Energy andstrength provide many advantages to those seeking to build power.

Just Say No!

The difference between successful people and very successful people is that very successful people say “no” to almosteverything. And that's what gives them the time to accomplish so much.{#blank#}2{#/blank#} And focus means saying “no” to a lot ofdistractions (分神).

Know What You Are!

I gnore your weakness and keep improvingyour strengths. Don't waste time exploring skill areas where you have littlecompetence. Instead, focus on—and build on—your strengths.{#blank#}3{#/blank#}

Create Good Luck!

      Luck is not magical—there is a science to it. Richard Wiseman studied lucky people for his book Luck Factor, and brokedown what they do right.{#blank#}4{#/blank#} By being more outgoing, open to new ideas,following the feeling that something is true, being optimistic, lucky peoplecreate possibilities.

      Does applying these principles to yourlife actually work? Wiseman created a “luck school” to test the ideas—and itwas a success. In total, 80 percent of people who attended Luck School saidthat their luck had increased. {#blank#}5{#/blank#} 

A. Spend enough time to improve yourweakness.

B. Achievement requires focus.

C. On average, these people reportedthat their luck had increased by more than 40 percent.

D. They never stop working and theynever lose a minute.

    How many calories are there in every meal you eat? That seems like a difficult question to answer. But students at Aitkin High School in the United States can easily answer it now. They put what they eat into an online calorie counter(计算器). It quickly measures the amount of calories in their meals.

    In fact, this is part of the school's health class. It includes heart health, nutrition and fitness. Students can learn basic knowledge about fats, proteins, calories and sugar.

    Students learn how to balance calories in and out. They will know what happens when the balance isn't there. “The online calorie counter has turned out to be a cool tool to help you make healthy choices. Making one healthy eating decision can really make a difference.” Adam Carlson, the teacher in charge, told local newspaper Aitkin Independent Age.

    They also discus good ways to burn calories in the gym. According to Carlson, the gym is a great place to burn calories and get stronger. But it doesn't work for everyone. So they try to find different workout tips. “I'm trying hard to teach the students that working out can be fun, challenging, and doesn't need to take hours out of the day,” she said.

    The class has indeed changed students. “I am now watching what I am eating and pay attention to the food labels,” said seventh-grader Karena Burgstaler. Another student James Erickson began to control his sugar input because it almost went over his daily calorie intake goal.

    Scientists have been studying how people use money for long. Now they're finding some theories may apply to one group of monkeys.

    Researchers recently taught six monkeys hos to use money. They gave the monkeys small metal disks (圆片) that could be used like cash and showed them some yummy apple pieces. The monkeys soon figured out that if they gave one of the disks to a scientist, they'd receive a piece of apple in return.

    If you think that is all the monkeys can figure out, you are wrong. Two researchers, Jake and Allison, acted as apple sellers in the experiments. The monkeys were tested one at a time and had 12 disks to spend in each experiment. Jake always showed the monkeys on apple piece, while Allison always showed two pieces. But that's not necessarily what they gave the monkeys. The number of apple pieces given for a disk was determined at random.

    Experiment One: Allison showed two pieces of apples but gave both piece only half the time. The other half, she took one piece away and gave the monkey just the remaining piece. Jake, on the other hand, always gave exactly what he showed: one piece for each disk. The monkeys chose to trade more with Allison.

    Experiment Two: Allison continued to sometimes gave two pieces and sometimes one piece. But now, half the time, Jake gave the one apple piece he was showing, and half the time he added a bonus. Guess what? The monkeys chose to trade more with Jake.

    In the first experiment, the monkeys correctly figured out that if they traded with Allison, they'd end up with more treats. In the second one, when a monkey received two pieces from Jake, it seemed like a gain. When Allison gave the monkey only one piece instead of the two she showed, it seemed like a loss. The monkeys preferred trading with Jake because they'd rather take a chance of seeming to win than seeming to lose.

    We also sometimes make silly business decisions just to avoid the feeling that we're getting less, even when we're not. Would you have made the same choices?

    The secret to living longer could be as simple as picking up your walking pace, according to a new study. Researchers from the University of Sydney found that walking at a brisk (快的) or fast pace was associated with a risk reduction of 24 percent for any cause of death.

    This effect was even more obvious in older age group, with fast walkers over the age of 60 reducing their risk of death by a surprising 53 percent. Professor Emmanuel Stamatakis, who led the study, explained, "A fast pace is generally five to six kilometers per hour, but it really depends on a walker's fitness levels; an alternatives indicator is to walk at a pace that makes you slightly out of breath or sweaty."

    In the study, the researchers looked at the results of 11 surveys from 1994 to 2008, in which participants recorded their walking pace, as well as age, sex and BMI. The analysis showed that walking at an average pace was associated with a 20 percent risk reduction for all-cause mortality (死亡率) compared with walking at a slow pace, while walking at a brisk or fast pace was associated with a risk reduction of 24 percent.

    The researchers hope the findings will encourage the development of public health message about the benefits of walking pace. Professor Stamatakis added, "These analyses suggest that increasing walking pace may be a straightforward way for people to improve heart health and risk for premature mortality—providing a simple message for public health campaigns to promote.

    "Especially in situations when walking more isn't possible due to time pressures or a less walking-friendly environment, walking faster may be a good option to get the heart rate up—one that most people can easily add to their lives."
