Honey from the African forest is not only a kind of natural sugar, it is also delicious. Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper—a little bird called a honey guide.

    The honey guide does not actually like honey, but it does like the wax(蜂蜡) in the beehives(蜂房). The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always falls to the ground, and this is when the honey guide takes its share.

    Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.

    You may not  have heard of Ashoka,  but for the past 27 years,this association, founded by Bill Drayton, has fought  poverty (贫穷)and sickness, promoted education and  encouraged small businesses. To support these worthy causes, Ashoka provides money for the world's most  promising "changemakers" seeking to solve (解决) urgent problems and would like to create a  world in which every citizen is a changemaker.

    Drayton believes that anyone can become an agent for change. The important thing is to simply give yourself permission. If you see a problem that you care about, you can help solve it. The young in particular are willing to accept this concept because at heart every child wants to grow into a happy, healthy,  contributing adult. In fact It is many young people's ambition to set up programmes or businesses that improve social conditions. An excellent example is an Ashoka project started in 1995 in Dhaka, which handled the rubbish problem facing the city ,helped local farmers and provided an income for poor people there .

When Masqsood and Iftekhar began to study the problem of all the uncollected rubbish that lay in Dhaka's streets, Attracting tats and disease , they discovered that 80% of it was natural waste . So they educated the poor people in the city to compost (把……制成堆粪)this waste . They knew that they would have a market for the end product because local farmers were struggling with chemical ferntilisers (化肥) which were expensive and had reduced the natural minerals in the soil over the years . At first , they were refused ,but once they were able to persuade them that there was money to be made , the project took off. In 2009 sales were $14,000.

    Drayton is optimistic that in ten years Ashoka will be making really serious ,practical progress in bringing about social change by changing the way we look at economic development.

    How a few members of the animal kingdom handle the transition to adulthood?

    African elephants

These beautiful beasts come close to imitate teen rebellion. Calves spend a decade with their mothers in female-dominated groups —- and ladies stay there —- but adolescent boys leave mom for noisy crews of bros. In their 20s, they often downsize to smaller male groups.

    Orangutans (猩猩)

Slow metabolism allows these primates to survive food shortages —- times when weather makes ripe fruit scarce. But energy efficiency comes at a cost; growth and maturation take time. Orangutan mamas nurse their young longer than any other wild creature does.

    Orcas(逆戟鲸)

    Killer whales join their mother's familial group for life. This lasting-relationship seems to increase a pup's chance of survival; if mom dies  a young male (under 30) is three times more likely to die than a peer whose mother is alive. Risk of death post-mom-mortem rises as kids get older.

Harp seals

A harp seal's "childhood" lasts just 12 days. A pup's sole purpose during that brief period of coddling(宠爱) is to constantly nurse, gaining a fifth of its birth weight in blubber(鲸脂) every day. Once it's fat —- they become greater from 25 to 80 pounds —- it slides off the ice and takes on the sea.

    Wolf spiders

    Every parent knows that tired toddlers love to hitch a piggyback ride. The wolf spider straps all her babies (40 or 50, on average) onto her back at once, carrying the brood until they are capable of fully functional spider-hood. But luckily she only has to pull them for a few days.

    The University of Birmingham is the first excellent UK Russell Group university to announce that it will accept the "Gaokao" exam for high­flying Chinese students wishing to join its undergraduate courses in 2019. High school students who complete the "National Higher Education Entrance Examination", or Gaokao, with top grades will be able to apply for direct entry onto Birmingham degree programmes without first completing a foundation year which is a routine for the freshman.

    Gaokao is usually taken by students in their last year of senior high school and, every year, each province in China sets the grades required to gain admission to its universities. It is usually held across China in early June. Students are tested in Chinese, Mathematics, a Foreign Language and social sciences or natural sciences.

    University of Birmingham Vice­Chancellor Professor Sir David Eastwood said: "The University of Birmingham has been challenging and developing great minds for more than a century. We welcome people from around the globe to study at Birmingham and Chinese students form an integral part of our education and research community. We are further opening access to Birmigham's wealth of education opportunities for the brightest and most dedicated Chinese students by accepting this strict and important qualification. I look forward to welcoming these high­flying students to the University of Birmingham."

    Gaokao is increasingly accepted by universities in Australia, the USA, Canada and mainland Europe. Birmingham will only be considering high quality students who achieve a minimum 80% Gaokao score and meet additional academic and English language requirements.

    Professor J on Frampton, Director of the University of Birmingham's China Institute said: "The University of Birmingham has a long history of educating students from China and one of our most famous graduates is Li Siguang­the founding father of Chinese geology. I am delighted that the University is now accepting the Gaokao. This gives the brightest and best Chinese students an opportunity to move straight into the first year of our undergraduate programmes and experience the benefits of studying at a global Top 100 university, such as Birmingham."

    A few hours after my first mission, returning to Earth on the space shuttle Endeavour, I completed all of my medical tests after flight, met with NASA officials, and reunited with my family. Finally, I was alone in my office room in astronaut crew quarters at the Kennedy Space Center, exhausted and ready for bed. And I did what anyone does when they return to their hotel room on a business trip: I turned on the TV. The television news started up: Such and such had happened, people were shocked, blah blah blah. Sports scores. Silly commercials.

    It didn't take more than a minute before I had to turn it off. It felt like my body was rejecting all this input, just as it would reject an organ donation that had the wrong blood type. All of this noise was just completely foreign to who I was—or, more appropriately, who I had become. A few hours before, I had been orbiting Earth, seeing our planet from space, flying the most amazing machine ever built by human hands, working with a team that was the absolute success of human. And now here in my room watching what was being sold as news, and with my newfound perspective, I just could not stomach it. My worldview was changed forever in a profound (深刻的) way.

    The biggest change by far and the one for which I will always be most grateful is this big-picture perspective. That will stick with me for the rest of my life.

    Whenever I feel the pressure of modern life, the stress about work, or worry about the future, I remember my time in the space station. Back to seeing the sun set Or watching our galaxy rise on the horizon. Or seeing a sea of lightning flash a hundred times a second. Or simply back to floating weightlessly.

    When I'm there in my mind and realize how many billions of these beautiful sunsets there have been and will be in the future, the cares of the world just don't seem that pressing. It goes that, "Do not worry about tomorrow, for tomorrow will worry about itself." Living daily life down here on the planet is so much better with this attitude!
