Lakes,Too,Feel Global Warming
There's no doubt:In the last few decades,the average temperature on Earth has been higher than it has been in hundreds of years.Around the world,people are starting to measure the effects of global warming一 and trying to figure out what to do about it.
Scientists recently used satellites to study the temperatures of lakes around the world,and they found that lakes are heating up.Between 1985 and 2009,satellites recorded the nighttime temperatures of the sur- faces of 167 lakes.During those 24 years,the lakes got warmer by an average of about 0.045 degree Celsius per year.
In some places,lakes have been warming by as much as 0.10 degree Celsius per year.At that rate,a lake may warm by a full degree Celsius in just 10 years.That difference may seem small一you might not even notice it in your bath.But in a lake,slightly warmer temperatures could mean more algae（水藻）,and algae can make the lake poisonous to fish.
The study shows that in some regions,lakes are warming faster than the air around them.This is impor- tant because scientists often use measurements of air temperature to study how Earth is warming.By using lake temperatures as well,scientists can get a better picture of global warming.The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.
That's going to be useful,since no country is too big or too small to ignore climate change.Scientists aren't the only ones concerned.Everyone who lives on Earth is going to be affected by the rapid warming of the planet.Many world leaders believe we might be able to do something about it,especially by reducing the amount of greenhouse（温室）gases we put into the air.
That's why the United Nations started the Framework Convention on Climate Change,or UNFCCC.
Every year the convention meets,and representatives from countries around the world gather to talk about climate change and discuss global solutions to the challenges of a warming world.

The iPad
1 The iPad is a tablet computer（平板电脑）designed and developed by Apple.It is particularly mar- keted as a platform for audio and visual media such as books , periodicals（期刊）, movies , music , and games, as well as web content.At about 1.5 pounds(680 grams),its size and weight are between those of most con- temporary smartphones and laptop computers.Apple released the iPad in April 2010,and sold 3 million of the devices in 80 days.
2 The iPad runs the same operating system as iPod Touch and iPhone.It can run its own applications as well as ones developed for iPhone.Without modification,it will only run programs approved by Apple and distributed via its online store.
3 Like iPhone and iPod Touch,the iPad is controlled by a multitouch display一a break from most pre- vious tablet computers , which uses a pressure-triggered stylus（触控笔）.The iPad uses a Wi-Fi data connec- tion to browse（浏览）the Internet , load and stream media, and install software.Some models also have a 3 G wireless data connection which can connect to GSM 3 G data networks.The device is managed and synchro- nized（同步）by iTunes on a personal computer via USB cable.
4 An iPad has different features and applications one can use to execute different and interesting things.There are lots of iPad applications that the owner can use to enhance the way they communicate.Some of these are how to use social networking sites and other online options.One of the most common uses is for e-mail services.iPad applications like Markdown Mail allow the adoption of specific and particular options.
They enable the owner to personalize their email accounts.
5 While the iPad is mostly used by consumers it also has been taken up by business users.Some com- panies are adopting iPads in their business offices by distributing or making available iPads to employees.
Examples of uses in the workplace include lawyers responding to clients,medical professionals accessing health records during patient exams,and managers approving employee requests.A survey by Frost&Sulli- van shows that iPad usage in workplaces is linked to the goals of increased employee productivity,reduced paperwork,and increased revenue.

Cell Phones: Hang Up or Keep Talking?
Millions of people are using cell phones today.In many places it is actually considered unusual not to use one.In many countries,cell phones are very popular with young people.They find that the phones are more than a means of communication一having a mobile phone shows that they are cool and connected.
The explosions around the world in mobile phone use make some health professionals worried.Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones.In England,there has been a serious debate about this issue.Mobile phone companies are worried about the negative publicity of such ideas.They say that there is no proof that mobile phones are bad for your health.
On the other hand,why do some medical studies show changes in the brain cells of some people who use mobile phones?Signs of change in the tissues of the brain and head can be detected with modern scanning （扫描）equipment.In one case , a traveling salesman had to, retire at a young age because of serious memory loss.He couldn't remember even simple tasks.He would often forget the name of his own son.This man used to talk on his mobile phone for about six hours a day,every day of his working week,for a couple of years.His family doctor blamed his mobile phone use,but his employer's doctor didn't agree.
What is it that makes mobile phones potentially harmful?The answer is radiation.High-tech machines can detect very small amounts of radiation from mobile phones.Mobile phone companies agree that there is some radiation,but they say the amount is too small to worry about.
As the discussion about their safety continues,it appears that it's best to use mobile phones less often.
Use your regular phone if you want to talk for a long time.Use your mobile phone only when you really need it.Mobile phones can be very useful and convenient,especially in emergencies.In the future,mobile phones may have a warning label that says they are bad for your health.So for now,it's wise not to use your mobile phone too often.

The Book of Life
So far,scientists have named about 1.8 million living species,and that's just a fraction of what proba- bly exists on Earth.With so many plants,animals,and other creatures covering the planet,it can be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.
A soon-to-be-launched Web site might help.An international team of researchers has announced the creation of a Web-based Encyclopedia of Life(EoL).The project aims to catalog every species on Earth in a single,easy-to-use reference guide.
To get the encyclopedia started,the creators will use information from scientific databases that already exist.And eventually,in special sections of the site,nonscientists with specialized knowledge will get to join in.Bird-watchers,for example,will be able to input which birds they've seen and where.The technology for this kind of tool has only recently become available.
As the EoL develops, you might find it useful for school projects.The site will feature special pages for kids who are studying ecosystems（生态系统）in their neighborhoods.To make sure the encyclopedia is accurate,scientists will review much of the information added to it.People who visit the site will be able to choose to leave out pages that haven't been reviewed.
Another convenient feature of the EoL is that you'll be able to pick the level of detail you see to match your interests,age,and current knowledge.If you wanted to learn about bears for a science class report,for example,you could use the"novice"setting to get basic information about the animals.On the"expert" setting,on the other hand,you could get much more detailed information about the history,literature and exploration of bears.
It now takes years for scientists to collect all the data they need to describe and analyze species.The creators of the Encyclopedia of Life hope that their new tool will speed that process.

Longer Lives for Wild Elephants
Most people think of zoos as safe places for animals,where struggles such as having difficulty finding food and avoiding predators（猛兽）don't exist.Without such problems,animals in zoos should live to a ripe （成熟的）old age.
But that may not be true for the largest land animals on Earth.Scientists have known that elephants in zoos often suffer from poor health.Sometimes,they even become unable to have babies.
To learn more about how captivity（圈养）affects elephants, a team of international scientists compared the life spans of female elephants born in zoos with female elephants living outdoors in their native lands.
Zoos keep detailed records of all the animals in their care,documenting factors such as birth dates,illnes- ses,weight and death.These records made it possible for the researchers to analyze 40 years of data on 800 African and Asian elephants in zoos across Europe.The scientists compared the life spans of the zoo-born fe- male elephants with the life spans of thousands of wild female elephants in Africa and Asian elephants that work in logging camps（伐木场）, over approximately the same time period.
The team found that female African elephants born in zoos lived an average of 16.9 years.Their wild counterparts who died of natural causes lived an average of 56 years一more than three times as long.Female Asian elephants followed a similar pattern.In zoos,they lived 18.9 years,while those in the logging camps lived 41.7 years.
Scientists don't know yet why wild elephants seem to get on so much better than their zoo-raised coun- terparts.Georgia Mason,a biologist at the University of Guelph in Canada who led the study,thinks stress and obesity（肥胖症）may be to blame.Zoo elephants don't get the same kind of exercise they would in the wild,and most are very fat.Social lives of elephants are also much different in zoos than in the wild,where they live in large herds and family groups.
The study raises some questions about acquiring more elephants to keep in zoos.While some threatened and endangered species living in zoos reproduce（生殖）successfully and maintain healthy populations,that doesn't appear to be the case with elephants.

Flying into History
When you turn on the television or read a magazine , celebrities（名人）are everywhere.Although fame and the media play such major roles in our lives today,it has not always been that way._______________(46)
Many historians agree that Charles Lindbergh was one of the first major celebrities,or superstars.
Lindbergh was born in Detroit,Michigan,in 1902,but he grew up in Little Falls,Minnesota.As a child,he was very interested in how things worked,so when he reached college,he pursued a degree in en-gineering.At the age of 20, however, the allure（诱惑）of flying captured Lindbergh' s imagination.
_______________(47)Soon after,Lindbergh bought his own plane and traveled across the nation performing aerial stunts（空中特技）.
In 1924,Lindbergh became more serious about flying.He joined the United States military and graduated first in his pilot class._______________(48)
During the same time,a wealthy hotel owner named Raymond Orteig was offering a generous award to the first pilot who could fly nonstop from New York City to Paris,France.The Orteig Prize was worth $25,000一a large amount even by today's standards.
Lindbergh knew he had the skills to complete the flight,but not just any plane was capable of flying that far for that long.______________ (49)
On May 20,1927,Charles Lindbergh took off from Roosevelt Field in New York City and arrived the next day at an airstrip（简易机场）outside Paris.Named in honor of the sponsor , The Spirit of St.Louis car- ried Lindbergh across the Atlantic Ocean and into the record books.He became a national hero and a huge celebrity.
When he returned to the United States , Lindbergh rode in a ticker-tape（热烈的）parade held to cele-brate his accomplishment._______________(50)
A very popular dance was even named for Charles Lindbergh一 the Lindy Hop.Today,The Spirit of St.Louis is kept at the Smithsonian institute'5 National Air and Space Museum in Washington,D.C.
