The 67-year-old Shandong Province native, Ge Yuxiu, has lived in Qinghai Province for 51 years. For almost half that time, he has been on the Qinghai-Tibet Plateau, where he has devoted his life to photographing and protecting wild animals.
Despite serious heart trouble, Ge is determined to stay on the high-altitude Plateau and continue to do something to help protect wildlife in the area.
Ge's enthusiasm for photography grew after his photo of soldiers reading news written on a blackboard was published in Qinghai Daily in 1979. He probably would never have turned to photographing wild animals without a visit to Bird Island in Qinghai Lake in 1995, after he had retired from the army and had begun working in the financial sector.
Covering less than half a square kilometer, the island is home to over 100,000 migratory birds. "I became addicted to the bird kingdom," Ge said, adding that he has so far visited the island more than 200 times to take photos.
He never expected that his attraction to the island would tie his destiny with Przewalski's gazelle (普氏原羚), a relatively small, slender antelope endemic (特有的) to China. Ge went to the island in late 1997 to take photos of swans when he saw seven yellowish-brown animals running across the grass-lands, in a line. On hearing one of his companions shouting "Przewalski's gazelle", he took out his camera and took photos of them. He was later told by wildlife conservation experts that he had captured the world's first image of this kind of antelope.
"I was so excited to hear that," he said. His excitement, however, soon gave way to anxiety after he learned about the animal's endangered status. Only found around Qinghai Lake, there were just 300 of them surviving in the wild at the time. The incident became a turning point in Ge's photography career, as he decided to devote his efforts to saving the gazelle and other endangered animals. He often spent time in the wild observing the gazelle and occasionally visited local herdsmen to learn what they knew about the animal.
Thanks to joint efforts, the population of Przewalski's gazelle has now increased to about 2,700.
Languages have been coming and going for thousands of years, but in recent times there has been less coming and a lot more going. When the world was still populated by hunter-gatherers，small，tightly knit(联系)groups developed their own patterns of speech independent of each other. Some language experts believe that 10,000 years ago, when the world had just five to ten million people, they spoke perhaps 12, 000 languages between them. Soon afterwards, many of those people started settling down to become farmers, and their languages too became more settled and fewer in number. In recent centuries, trade, industrialisation, the development of the nation-state and the spread of universal compulsory education, especially globalisation and better communications in the past few decades, all have caused many languages to disappear, and dominant languages such as English，
Spanish and Chinese are increasingly taking over.
At present, the world has about 6, 800 languages. The distribution of these languages is hugely uneven. The general rule is that mild zones have relatively few languages, often spoken by many people, while hot wet zones have lots, often spoken by small numbers. Europe has only around 200 languages; the Americas about 1, 000; Africa 2, 400; and Asia and the Pacific perhaps 3,200, of which Papua New Guinea alone accounts for well over 800.The median number(中位数) of speakers is mere 6,000, which that half the world's languages are spoken by fewer people than that.
Already well over 400 of the total of 6, 800 languages are close to extinction (消亡), with only a few elderly speakers left. Pick, at random, Busuu in Cameroon （ eight remaining speakers), Chiapaneco in Mexico (150), Lipan Apache in the United States (two or three) or Wadjigu in Australia (one, with a question-mark): none of these seems to have much chance of survival.
We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置)well after they go out of style. That's bad news for the environment- and our wallets - as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life - from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s.Devices were grouped by generation. Desktop computers， basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997.And WP3 players, smart phones, and LCD TVs entered homes in 2002，before tablets and e-readers showed up in 2007.
As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day，you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices - We continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions (排放) more than doubling during the 1992 to 2007 window.
So what' s the solution(解决方案)? The team' s data only went up to2007， but the researchers also explored
what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.
Interruptions are one of the worst things to deal with while you're trying to get work done. ,there are several ways to handle things. Let's take a look at them now.
. Tell the person you're sorry and explain that you have a million things to do and then ask if the two of you can talk at a different time.
When people try to interrupt you, have set hours planned and let them know to come back during that time or that you'll find them then. .It can help to eliminate(消除) future interruptions.
When you need to talk to someone, don't do it in your own office..it's much easier to excuse yourself to get back to your work than if you try to get someone out of your space even after explaining how busy you are
If you have a door to your office, make good use of it.. If someone knocks and it's not an important matter. excuse yourself and let the person know you're busy so they can get the hint(暗示) than when the door is closed, you're not to be disturbed.
A.If you're busy, don't feel bad about saying no
B.When you want to avoid interruptions at work
C.Set boundaries for yourself as your time goes
D.If you're in the other person's office or in a public area
E.It's important that you let them know when you'll be available
F.It might seem unkind to cut people short when they interrupt you
G.Leave it open when you're available to talk and close it when you're not
During my second year at the city college,I was told that the education department was offering a "free" course, called Thinking Chess, for three credits. I1 the idea of taking the class because, after all, who doesn't want to2 a few dollars? More than that, I'd always wanted to learn chess. And, even if I weren' t excited enough about free credits, news about our3 was appealing enough to me. He was an international grandmaster, which4 I would be learning from one of the game's best I could hardly wait to5 him.
Maurice Ashley was kind and smart, a former graduate returning to teach, and this job was no game for him ; he meant business. In his introduction, he made it6 that our credits would be hard-earned. In order to7 the class among other criteria, we had to write a paper on how we plan to8 what we would learn in class to our future professions and9 to our lives. I managed to get an A in that course and leaned life lessons that have served me well beyond the10 .
Ten years after my chess class with Ashley, I' m still putting to use what he11 me："the absolute most important12 that you learn when you play chess is how to make good13 . On every single move you have to14 a situation, process what your opponent (对手) is doing and15 the best move from among all your options." These words still ring true today in my role as a journalist.
According to a review of evidence in a medical journal, runners live three years (long) than non-runners, You don't have to run fast or for long (see) the benefit. You may drink, smoke, be overweight and still reduce your risk of (die) early by running.
While running regularly can't make you live forever，the review says it (be)more effective at lengthening life walking, cycling or swimming. Two of the authors of the review also made a study published in 2014 showed a mere five to 10 minute a day of running reduced the risk of heart disease and early deaths from all （cause）.
The best exercise is one that you enjoy and will do. But otherwise...it's probably running. To avoid knee pain, you can run on soft surfaces, do exercises to (strength) your leg muscles (肌肉), avoid hills and get good running shoes. Running is cheap, easy and it's always (energy). If you are time poor, you need run for only half the time to get the same benefits as other sports, so perhaps we should all give a try.

Dear Sir / Madame,
Yours,

A couple，whom we shall call John and Mary, had a nice home and two lovely children. One day, John and Mary decided to go on a trip to another city, so they found a kind woman to look after the children and left.
Several days later, they returned home a little earlier than they had planned. As they drove back to their hometown, John and Mary noticed smoke and went to see what it was. They found a house was on fire. "Oh, well, it isn't our house. Let's go home," Mary said.
But John drove closer and screamed in surprise，"That's Jordan's home. He works in a factory. He wouldn't be off work yet. Maybe there is something we can do to help."
"It has nothing to do with us," cried Mary. "You have your good clothes on, so let's not get any closer."
John didn't listen to Mary. He drove up and stopped. They were both shocked to see the whole house was on fire. A woman was crying in the yard, "The children! Get the children!"
John seized her by the shoulder and shouted to her, "Don't cry! Tell me where the children are!" "In the basement(地下室)，"cried the woman, "down the hall and to the left."
John used water to get his clothes wet and put a wet towel on his head before rushing to the basement. The house was full of smoke and fire, and it was very difficult for him to find the children. But he made it. He held one under each arm. As he left，he could hear some more crying. He took the two kids out of the house and into the fresh air，and then asked the women how many more children were still down there.
