Nola (August 21, 1974 -November 22, 2015) was a northern white rhino who lived at the San Diego Zoo Safari Park near Escondido, California. At her death, she was one of only four remaining northern white rhinos in the world. The other three lived in Kenya. World Rhino Day, held on September 2, is to raise awareness(意识) of the less than 30,000 other rhinos left on Earth.

    “Rhinos need our help today, not tomorrow,” Nola's lead keeper Jane Kennedy said. “Last year we lost over 1,200 rhinos just in South Africa. If we continue to lose more than 1,000 rhinos a year, in 10 to 20 years all the rhinos on the planet will be gone.”

    “Unfortunately, most animals are in danger of dying out because of humans,” Kennedy says.“ Humans have either poached animals, or because there are over seven billion of us, we've taken up too much of the world's resources”. Poachers illegally hunt rhinos for their horns. They sell the horns for thousands of dollars per pound, to be used for art, jewelry, and decorations. Experts believe that one rhino is poached every eight hours.

    In 1975, the San Diego Zoo Institute for Conservation Research started the Frozen Zoo, a program through which researchers have collected cell (细胞) samples from more than 8,000 different types of animals, including the northern white rhino. Scientists hope that by studying the rhino cells, they will get greater understanding of it, and will find ways to increase its numbers.

    Jane Kennedy describes World Rhino Day as “a celebration of rhinos along with an awareness campaign for everybody across the world to know that rhinos need our help.”At the San Diego Zoo, children and adults are welcome to visit and speak with zookeepers to learn about rhinos. But you don't have to live in San Diego to celebrate World Rhino Day. It is observed around the world, with zoos and wildlife parks holding special events and programs to teach people about rhinos, and enable them to see the animals up close.

    A MENTORING (导师制）program is giving life changing opportunities to Banbury youth. Young Inspirations was founded two years ago to provide mentoring sessions for students and unemployed young adults aged 11 to 21.

    Alex Goldberg, the program's founder, said： "We set up Young Inspirations because we wanted to give young people experiences which will potentially be life changing and broaden their outlook." "We try to create work experience opportunities that will really make a difference to our youth. For example, we've secured internships (实习）with world-famous firms such as Honda."

    "At a time of funding cutbacks, schools are finding it more and more difficult to offer this kind of mentoring because of that- It is extremely important that these opportunities are available both to help youth with their school work and grades and to give them opportunities which may help shape their futures." Kieran Hepbum, 14, is one of a group of Banbury youth who has benefited from the program so far. In October the Banbury School pupil was accompanied by Young Inspirations staff to Paris where he was an observer at the United Nations Educational, Scientific and Cultural Organization's (UNESCO) International Youth Forum(论坛).

    The event was held for young people from around the world, to seek their views on how the future of youth and education should look. Kieran joined several hundred observers mostly in their 20s and was the only UK school pupil to attend the event. Kieran thinks the trip was a life changing experience. Before we left 1 didn't quite know what to make of it but when we got there we didn't stop, it was amazing" he said, "We went to three or four hours of debates each day and then did something cultural each afternoon."

    The main theme of the forum was how youth can drive change in political and public life. It  dealt with issues(问题）such as drug abuse, violence and unemployment. kieran said： It has really helped me to improve my confidence and social skills as well as my school grades and I was voted most improved pupil at school in August."

    The Young Inspirations mentoring sessions take place each Friday in Banbury. For details visit www.younginsviratiom.com.

    Many people have long dreamed of being able to fly around as simply as riding a bicycle.

    Yet the safety and strength of a flying bike was always a big problem. Over the past 10 years' developments in technology have moved the dream of personal flying vehicle closer to reality. Now, two groups of inventors say such vehicles may be available very soon.

    Grant Stapleton from Malloy Aeronautics says the Hoverbike, which is able to get in and out of small spaces very quickly, will be a truly personal flying vehicle." It can be moved across continents very quickly because it can be folded and packed," he adds.

    Mr. Stapleton says safety was the company's main concern when developing the Hoverbike, He says the designers solved the safety issue by using overlapping rotors (折叠旋翼)to power the vehicle. The company is testing both a one-third size model and a full-size prototype (原型))of the Hoverbike.

    Inventors say their Hovebike will most likely be used first by the police and emergency rescue teams.

    In New Zealand, the Martin Aircraft Company is also testing a full-size prototype of its personal flying bike, called Jetpack. It can fly for more than 30 minutes, up to 1,000 meters high and reach a speed of 74 kilometers per hour.

    Peter Coker is the CEO of Martin Aircraft Company. He said Jetpack" is built around safety from the start" In his words, reliability is the most important part of it. We have safety built into the actual structure itself very similar to a Formula One racing car."

    Jetpack uses a gasoline-powered engine that produces two powerful jet streams. Mr. Coker says it also has a parachute (降落伞)that can be used should there be an emergency.

    "It opens at a very low altitude and actually saves both the aircraft and the pilot in an emergency," he adds.

    Everybody sleeps, but what people stay up late to catch or wake up early in order not to miss varies by culture.

    From data collected, it seems the things that cause us to lose the most sleep, on average, are sporting events, time changes, and holidays.

    Around the world, people change sleep patterns thanks to the start or end of daylight-saving time（夏令时间）. Russians, for example, began to wake up about a half-hour later each day after President Vladimir Putin shifted the country permanently to "winter time" starting on October 26.

    Russia's other late nights and early mornings generally correspond（相一致）to public holidays. On New Year's Eve, Russians have the world's latest bedtime, hitting the hay at around 3:30 a. m.

    Russians also get up an hour later on International Women's Day, the day for treating and celebrating female relatives.

    Similarly, Americans' late nights, late mornings, and longest sleep fall on three-day weekends.

    Canada got the least sleep of the year the night it beat Sweden in the Olympic hockey（冰球）final.

    The World Cup is also chiefly responsible for sleep deprivation. The worst night for sleep in the U. K. was the night of the England-Italy match on June 14. Brits stayed up a half-hour later to watch it, and then they woke up earlier than usual the next morning thanks to summer nights, the phenomenon in which the sun barely sets in northern countries in the summertime. That was nothing, though, compared to Germans, Italians, and the French, who stayed up around an hour and a half later on various days throughout the summer to watch the World Cup.

    It should be made clear that not everyone has a tool to record their sleep patterns; in some of these nations, it's likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that's the case, the above findings are still striking. If the most health-conscious among us have such deep swings（明显改变）in our sleep levels throughout the year, how much sleep are the rest of us losing?

    Why is it that many people who have suffered a major shock, such as divorce or death of a family member, seem to be weaker against a variety of major and minor illness? One common idea among psychologists has been that people could deal with suffering more effectively if they were able to understand and accept it. Indeed, many experts stress the value of expressing thoughts and feelings connected with upsetting events.

    Recently, a team of medical researchers studied the links between describing psychologically painful events and long-term health. In one experiment healthy college students were asked to write about either personally disturbing experiences or ordinary topics over a period of four days. In the months afterwards, students who had chosen to show their inner thoughts and feelings in their writing visited the health center for illness much less often than those who had written about everyday topics.

    In an experiment that followed, another group of healthy students were given the four-day writing exercises. Some chose to write about highly personal and upsetting experiences (including loneliness, problems with family and friends, and health). When questioned immediately afterwards, they said that they did not feel any better. However, their blood samples(样本) taken before and after the experiment showed evidence of an improved resistance to illness. The white cells that fight off bacteria and viruses had increased their reaction and sensitivity to these "invaders". This trend continued over the following six weeks, when another blood sample was taken. Individuals who showed the best results were those who wrote about topics that they had actively kept from telling others about.

    The researchers suggested that failure to face up to painful experience can be a form of stress itself, and can increase the possibility of illness. It follows, then, that actively dealing with a major shock makes possible its understanding and acceptance. The answer is not to suffer in silence. It may not always be possible to talk about personal problems, but writing them down will help the body to fight disease in the long run.

When {#blank#}1{#/blank#} (ask) by a TV reporter to talk about air and water quality in his hometown, Qi Mu noted, "The air is great now, and we can take more walks and enjoy being outdoors again." He felt quite pleased because the villagers were living {#blank#}2{#/blank#} (harmonious) with nature once more. However, he could not forget about an earlier time {#blank#}3{#/blank#} his village had been struggling with a serious air quality problem.

In the 1990s, garbage from nearby city was usually brought to the village. "How can we make use of this?" The villagers wondered. Soon they found that garbage could be used {#blank#}4{#/blank#} (feed) pigs. "Over the next few years, {#blank#}5{#/blank#} (dozen) of pig farms were set up," Qi recalled. But then nobody in the village wanted to open their windows. "The smell from the garbage and pig waste was making us sick," Qi said. The numbers of mosquitoes and flies were also {#blank#}6{#/blank#} (horrify). "Under such circumstances, no single women wanted to marry anyone in our village and move here," Qi {#blank#}7{#/blank#} (sigh).

The villagers could no longer tolerate the situation. So {#blank#}8{#/blank#} initiative was launched and "clean-up" campaign was added to the government agenda, including restricting large vehicles {#blank#}9{#/blank#} passing through the village. Garbage from the city was no longer disposed of in the village and more trees were planted. "We can all breathe more freely now that the natural beauty of our village {#blank#}10{#/blank#} (restore) since then," said Qi.
