Jimmy is an automotive mechanic, but helost his job a few months ago. He has good heart, but always feared applyingfor a new job.

One day, he gathered up all his strengthand decided to attend a job interview. His appointment was at 10 am and it wasalready 8:30. While waiting for a bus to the office where he was supposed to beinterviewed, he saw an elderly man wildly kicking the tyre(轮胎） of hiscar. Obviously there was something wrong with the car. Jimmy immediately wentup to lend him a hand. When Jimmy finished working on the car, the old manasked him how much he should pay for the service. Jimmy said there was no needto pay him; he just helped someone in need, and he had to rush for aninterview. Then the old man said, “Well, I could take you to the office foryour interview. It's the least I could do. Please. I insist.” Jimmy agreed.

    Upon arrival, Jimmy found a long line ofapplications waiting to be interviewed. Jimmy still had some grease on himafter the car repair, but he did not have much time to wash it off or have achange of shirt. One by one, the applicants left the interviewer's office withdisappointed look on their faces. Finally his name was called. The interviewerwas sitting on a large chair facing the office window. Rocking the chair backand forth, he asked, “Do you really need to be interviewed?” Jimmy's heartsank. “With the way I look now, how could I possibly pass this interview?” hethought to himself.

    Then the interviewer turned the chairand to Jimmy's surprise, it was the old man he helped earlier in the morning.It turned out he was the General Manager of the company.

  “Sorry I had to keep you waiting, but Iwas pretty sure I made the right decision to have you as part of our workforcebefore you even stepped into the office. I just know you'd be a trustworthyworker. Congratulations!” Jimmy sat down and they shared a cup of well-deservedcoffee as he landed himself a new job.

    The past two decades have seen astronomers' catalogue of planets expand over two hundred times, as new techniques and better telescopes have found more than 2,000 of them orbiting stars other than the sun. But in the solar system itself, the list of planets has actually shrunk, Pluto（冥王星）having been downgraded from that status in 2006. The number of the sun's planetary companions has thus fallen from nine to eight.

    Now, a pair of astronomers from the California Institute of Technology think they have evidence that will restore the sun's record to its previous value. Their analysis of objects orbiting in the Kuiper Belt（柯伊伯带）, a ring of frozen asteroids（小行星）that circle beyond the orbit of Neptune (and of which Pluto is now regarded as the largest member), suggests to them that something about ten times as massive as Earth has changed those orbits. If you knew where to look, this planet-sized object would be visible through a suitable telescope. And Konstanin Batygin and Michael Brown believe they do know.

As they write in the Astronomical journal, they have analyzed the orbits of Kuiper Belt objects and found six that behave in a peculiar way. As the diagram shows, the points of closest approach of these objects to the sun, known as their perihelia（近日点）, almost coincide. Moreover, these perihelia all lie near the ecliptic（黄道）—the plane of Earth's orbit and also, approximately, that of the other planets—while the objects' orbits are all angled at 30° below the ecliptic. The chance of all this being a coincidence, the two researchers estimate, is about seven in 100,000. If it is not a coincidence, it suggests the six objects have been guided into their orbits by the gravitational intervention of something much larger.

    A computer analysis Dr Batygin and Dr Brown performed suggests this something is a planet weighing 5-15 times as much as Earth, whose perihelion is on the opposite side of the sun from the cluster, and which thus orbits mainly on the other side of the solar system from the objects its orbit has affected. This planet's perihelion would be 200 times farther from the sun than Earth's, and the far end of its orbit might be as much as six times that distance away. This gives a search zone, and Dr Batygin and Dr Brown are using Subaru, a Japanese telescope, to perform that search.

    Given other demands on Subaru's time, it might take five years for this search to find (or not find) the hypothetical planet. But looking at some existing data from. The Widefield Infrared Survey Explore, a satellite, might also show it, if it is there to be seen.

    Ironically, it was Dr Brown as much as anyone who was responsible for Pluto's downgrading, for he discovered Eris, an object almost as big as Pluto, in 2005.

    That discovery did much to damage Pluto's planetary proof. By his own admission, he was skeptical that the anomalies he and Dr Batygin have investigated actually would point to the existence of a replacement ninth planet. He is a skeptic no longer. Whether he is actually right may soon become apparent.

    We're often reminded of the importance of preserving the planet as we see it for future generations—and children at St Oswald's Primary School in Chester certainly agree.

    Nine-year-old Isobel Kelleher from the school's Hummingbirds class thinks adults need to take note. “Sometimes they can be busy and I don't think they think they can make a difference，but if everyone does a little bit it all adds up，” she tells HuffPost UK.“ We started looking at plastic pollution in our oceans and the things like plastic bags and broken down pieces of plastic that are polluting them.” she says.“ Fish can eat the plastic and they can die，or we might even eat the fish ourselves.”

    Mr Timms，Isobel's teacher，has been spearheading a new project at the school which lets children loose creatively to raise awareness of the need to be more environmentally friendly. The entire Hummingbirds class，which is made up of 9 and 10-year-old pupils，has been busy writing poems and creating online video adverts to warn adults about the serious situation of our oceans and wildlife.

    Mr Timms thinks children have an important role to play in teaching us how to take care of the things around us. We sometimes overlook how much we can really learn from children.” he says.“ It has been really hard to believe having parents come in saying that their children have been asking them to stop using plastic，and to recycle more，and even stopping them using plastic straws.”

    Mr Timms is proud of his Hummingbirds class.“ The message that they would like to send to the world is simple stopping this isn't someone else's job，and it won't be OK if we just leave it.”

The Philippines is trying to stir up trouble and undermine regional peace in the South China Sea. People may {#blank#}1{#/blank#}(对…感到困惑) why such a small country dares to provoke China, a superpower in the world. It is all because the Philippines wants to conquer Ren'ai Reef, {#blank#}2{#/blank#}(以及) some other reefs in the South China Sea. The Philippines allies with the US, attempting to seize these reefs located off its coast. But {#blank#}3{#/blank#}(有明确的证据) these reefs {#blank#}4{#/blank#}(属于) China. The Chinese government will never ever let these reefs {#blank#}5{#/blank#}(脱离) our motherland as they are treasures passed down from our ancestors. 

On Saturday, the Philippines once again sent two coast guard ships and a supply ship in an attempt to transport construction materials to the disintegrating warship illegally grounded on the reef in 1999. In response, the Chinese Navy also sent a fleet of warships to {#blank#}6{#/blank#}(保卫仁爱礁水域免受 ) the intrusion. Now that the whole area {#blank#}7{#/blank#}(被包围) hundreds of civilian ships and warships, there is no slightest chance for the Philippines' ships to approach. Thanks to the great {#blank#}8{#/blank#}(中国已取得的成就), it will never have an inch of its territory {#blank#}9{#/blank#}(被带走). What the Chinese Navy has done recently {#blank#}10{#/blank#}(让我感到自豪) being a Chinese.
