6.Sleeping for less than six hours a night greatly increases the risk of dying from a heart attack or stroke(中风),a study has found.It is the stuff of nightmares for those whose busy work schedule or busy family life means getting up early and staying up late.Scientists claim that the modern tendency to delay going to bed in order to get through more of the items on the‘to do'list has serious health consequences.But take care.Those who have too much sleep are also more likely to suffer a heart attack.While the extra sleeping is unlikely to be the cause,long-term illnesses such as heart disease often make sufferers feel tired,so sleeping for longer than nine hours a night may be an early warning sign.
   Researchers found that those who slept for less than six hours were almost 50 per cent more likely to suffer a heart attack and 15 per cent more at risk of strokes.They believe that not having enough sleep disrupts the balance of two key hormones(激素),ghrelin(生长素)and leptin(瘦素),which control the appetite.Poor sleepers tend to eat more and are more likely to be fatter,so are at greater risk of high blood pressure and heart disease,which lead to heart attacks and strokes.Experts recommend adults get at least six or seven hours'shut-eye a night to stay healthy.
   But as many as 60 per cent of us do not think we are sleeping enough,with a third suffering from sleeplessness.The researchers,from the University of Warwick,warned that trying to push too much into one day by going to bed late and getting up early could lead to serious illnesses later in life.They looked at the sleeping habits of almost 475,000 participants from 15 previous studies across eight countries,including the UK,the U.S.,Japan,Sweden and Germany.Their findings,published in the European Heart Journal,show that those who slept for less than six hours were 48 per cent more likely to develop or die from heart disease and 15 per cent more likely to develop or die from a stroke.Not having enough sleep decreases the levels of leptin in our blood,which means we do not feel as satisfied after eating.At the same time,it raises the levels of ghrelin,responsible for triggering(引起) our appetite,thus making us feel hungrier.
   The scientists believe that our‘work hard,play hard'society encourages us to sacrifice sleep and ignore our health.The trend for late nights and early mornings is actually a ticking time bomb for our health so you need to act now to reduce your risk of developing these life-threatening conditions.
50.What's the main idea of the passage?A
A.Lack of sleep raises your risk of stroke or heart disease.
B.It raises the levels of ghrelin,thus making us feel hungrier.
C.Sleeping for longer than nine hours a night may be an early warning sign.

B.Because not having enough sleep decreases the levels of leptin in our blood.
C.Because not having enough sleep raises the levels of ghrelin,thus making us feel hungrier.

16.A year ago August,Dave Fuss lost his job driving a truck for a small company in west Michigan.His wife,Gerrie,was still working in the local school cafeteria,but work for Dave was scarce,and the price of everything was rising.The Fusses were at risk of joining the millions of Americans who have lost their homes in recent years.Then Dave and Gerrie received a timely gift-$7,000,a legacy (遗产) from their neighbors Ish and Arlene Hatch,who died in an accident."It really made a difference when we were going under financially."says Dave.
But the Fusses weren't the only folks in Alto and the neighboring town of Lowell to receive unexpected legacy from the Hatches.Dozens of other families were touched by the Hatches'generosity.In some cases,it was a few thousand dollars; in other,it was more than$100,000.

Children of the Great Depression,Ish and Arlene were known for their habit of saving.They thrived on(喜欢)comparison shopping and would routinely go from store to store,checking prices before making a new purchase.
Through the years,the Hatches paid for local children to attend summer camp when their parents couldn't afford it."Ish and Arlene never asked whether you needed anything,"says their friend Sand Van Weelden,"They could see things they could do to make you happier,and they would do them.
    Even more extraordinary was that the Hatches had their farmland distributed.It was the Hatches'wish that their legacy-a legacy of kindness as much as one of dollars and cents-should enrich the whole community and Ish and Arlene Hatch's story.

14.A disastrous competition is going on in England,with billions of dollars and hundreds of lives in danger.OK,that's not true.But competitors from around the world gathered on Thursday to compete for the title of 2012's World's Biggest Liar.
Each participant is given up to five minutes to make up the best lie in the competition,which was started in honor of 19th-century Bridge Inn owner Will Ritson,who was reportedly famous for his lies.Competitors gather at the Bridge Inn every year for the competition,a small pub in northwestern England.Anyone can take part in the competition.Well,almost anyway; the reporters note that lawyers and politicians are banned,who is said to enjoy"an unfair advantage"in the proceedings (进程).
A study published this past July in the journal Evolution & Human Behavior found that nearly all lies are detectable through visible facial muscle (肌肉) reactions in the person telling a lie."Thus,while interpersonal deception (欺骗) often is highly successful,signs of hidden emotional states are communicated clearly to the informed observer,"the study concluded.
A churchman of Carlisle reportedly holds what may be the greatest lie of all time in the competition,simply stating,"I have never told a lie in my life."
In 2003,Abrie Krueger of South Africa became the first non-Brit to win the competition.Ironically,Krueger was accused by some of cheating.
In 2006,comedian Sue Perkins became the first female to win the competition,telling a tale about people riding camels to work as a result of climate change.

1.Do you love running?It is a good exercise,yet many people find it boring.But what if making your morning jog a creative one?Like jumping from walls and over gaps,and ground rolls?Just like the James Bond in the movie Casino Royale?Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way.It is just because of Bond's wonderful performances that the sport has become popular worldwide.
  Yes,that's parkour,an extreme street sport aimed at moving from one point to another as quickly as possible,getting over all the obstacles in the path using only the abilities of the human body.Parkour is considered an extreme sport.As its participants dash around a city,they may jump over fences,run up walls and even move from rooftop to rooftop.

A parkour lover said,"I love parkour because its philosophy has become my life,my way to do everything."
