11．People who get a good workout almost daily can add nearly four years to their life spans，according to the first study to quantify the impact of physical activity this way．
The researchers looked at records of more than 5，000middle-aged and elderly Americans and found that those who had moderate to high levels of activity lived 1.3to 3.7years longer than those who got little exercise，with men and women benefiting about equally．
"This shows that physical activity really does make a difference--not only for how long you live but for how long you live a healthy life，"said Oscar H．Franco of the Erasmus M．C．University Medical Center in Rotterdam．"Being more physically active can give you more time．"
Previous studies have found that being physically active has a host of health benefits．It reduces the risk of being overweight and of developing many illnesses，improves overall quality of life，and lowers the mortality rate．But the new study is the first to directly calculate the effect on how long people live．
People who engaged in moderate activity--the equivalent of walking for 30minutes a day for five days a week--lived about 1.3to 1.5years longer than those who were less active．Those who took on more intense exercise--the equivalent of running half an hour a day five days every week--extended their lives by about 3.5to 3.7years，the researchers found．
The findings show that even for people who are already middle-aged，exercising more can add years to their lives，Franco said．
Other experts said the study was consistent with the growing evidence that exercising on a regular basis is one of the most important things people can do for their health．
"At the end of the day，this is more evidence that the sedentary lifestyle is the most devastating to health，longevity and chronic disease development，"said James O．Hill of the University of Colorado at Denver．
Hill and others said exercising regularly also enables people to live healthier lives，free from a host of chronic illnesses that can make it hard for people to enjoy their later years．
In addition，recent studies have also found that exercise has payoffs for the mind，too．It has been shown to improve overall well-being and reduce stress and depression．
"The benefits of physical activity extend well beyond the effects on longevity，"said Joann E．Manson of Harvard's Brigham and Women's Hospital in Boston．

18．NBA commissioner David Stern was in Orlando on Thursday night，getting ready for Sunday's All-Star Game．Of course，all he could talk about was the only player anyone wants to talk about these days：New York Knicks guard Jeremy Lin．
Hours before Lin took the court against the Heat，a few hundred miles South down I-95in Miami，Stern told reporters that Lin's instant popularity hasn't ever been matched in sports history，not even by Sunday's biggest names，LeBron James or Kobe Bryant．
The Associated Press had the details．
"I haven't done a calculation，but it's fair to say that no player has created the interest and the craze in this short period of time，in any sport，that I'm aware of like Jeremy Lin has，"Stern said Thursday．
Lin，an undrafted（未选秀的）guard from Harvard，has become the NBA's biggest story since coming off the Knicks'bench earlier this month to lead them to nine wins in 11games heading into their matchup with Miami on Thursday night．
With Lin's popularity in Asia as the league's first American-born player of Chinese or Taiwanese descent，and with the religious community because of his strong Christian faith，Stern says he's"never quite seen anything like"the attention on Lin．
"It's fascinating，"Stern said after the All-Star Jam Session opening ceremonies．
The top five videos on NBA．com since Feb.4，when Lin joined the circulation，are all Lin or Knicks related．Lin went from 190，000 followers on Sina，China's version of Twitter，on Feb.2to more than 1million as of Feb.16．
Indeed，Lin's popularity is so out of this world that the NBA made a late list switch to ensure his participation in the Rising Stars Challenge on All-Star Saturday，a game that includes the NBA's best rookies（新秀球员）and sophomores．Lin is in such high demand that all of the game's other participants will meet with the media following a team practice on Friday while Lin will have his own，separate press conference later in the night．
This is Jeremy's world，folks．We're all just living in it．Even David Stern and the rest of the league's All-Stars，at least for the moment．

59．The following statements about Jeremy Lin's instant popularity are true EXCEPT thatA．
A．Jeremy Lin led New York Knicks to win all the recent games this month
B．David Stern said Lin was the only instant popular player in NBA's history
C．Lin has become the NBA's greatest story though he was an undrafted guard
D．no player has created the interest and the enthusiasm in such a short period of time
60．Why did Jeremy Lin have so many followers in Asia on Sina，China's version of Twitter？B
A．Because Jeremy Lin was born in Taiwan with strong Christian faith．
B．Maybe because he is the first player born in America but has Chinese descent．
C．Because Sina has a large group of surfing people，maybe more than 10million．
D．Because the top five videos on NBA．com since Feb.4are all Lin or Knicks related．
61．The underlined phrase"out of this world"in Paragraph 9may probably be replaced byC．
A．impossible B．important C．exceptional D．excellent
62．What can we learn from the above passage about Jeremy Lin's instant popularity？C
A..Knowledge starts with practice．
B．Failure is the mother of success．
C．Every dog has its day．
D．No pains，no gains．

10．Australian cities can keep their native wildlife-but only if they can kick their habit of urban sprawl （无计划的扩展）．That's the finding of a new study by leading Australian environmental researchers Jessica Sushinsky，Professor Hugh Possingham and Dr Richard Fuller of The University of Queensland．
"While urban development usually reduces the number of birds in a city，building more compact （紧凑的） cities and avoiding urban sprawl can slow these reductions greatly，"says lead author Jessica Sushinsky．"Compact housing development leaves birds'homes untouched，leading to fewer losses of birds．"
The researchers surveyed native and wild birds in Brisbane's urban areas，including living and industrial areas，public parks and gardens，major roadways and airports．They then used statistical modeling to find out what will happen to the birds as the city grows．The first setting was compact growth-where multiple homes are built on land that previously had only one house．The second setting was sprawling growth-a familiar pattern where homes are built here and there beyond the city's current boundaries．
The team's forecasts showed that a much greater diversity of species was lost over 20 years in the sprawling setting compared to the more compact setting．"Urban sprawl resulted in the disappearance of many urban-sensitive birds-birds that only live in areas where there is native vegetation （植被），such as parklands and woodlands，"Ms Sushinsky says．
"On the other hand，we found the city with the compact development attracted more birds because it kept more of its parks and green areas．"
Now the Queensland Government has adopted the more compact urban growth strategy，which，Dr Richard Fuller says，is good news for Australia's native birds．These birds are environmental specialists-they need a particular environment to do well．"While compact development means smaller backyards，it can also make our entire cities more biodiverse，"according to Dr Fuller．"The study shows that we should hold on to our green spaces instead of clearing them for sprawling development．"
This is the first time science has modeled the effects of different urban growth strategies on birds，the researchers say．"Statistical models like these are important because they help us to understand the ecological consequences of a particular decision，"says Dr Fuller．
71．The study deals with the relationship betweenA．
A．city development and birds                        B．the environment and birds
C．humans and wildlife                               D．climate and wildlife
72．Why is compact urban growth better than the sprawling strategy？D
A．It makes the cities more beautiful．
B．It gives people larger backyards．
C．It is money-saving．
D．It is bird-friendly．
73．Dr Richard Fuller thinks the Queensland Government's actionB
A．is really brave
B．is worth praising
C．has an uncertain future
D．should be performed nationwide
