Today, the world's diversity (多样性) of food crops is quickly decreasing. But scientists around the world are taking action. They are building seed banks. At seed banks, scientists store the seeds of many different crops.

    There are now 1,400 seed banks around the world. However, some banks are in warm countries. If the electricity fails, the seeds will get too hot and die. Other seed banks are in countries troubled by war. Sometimes people damage the seed banks. If this happens, valuable seeds can be lost forever!

    The organization Global Crop Diversity Trust decided they wanted to deal with this problem. So, they decided to build a global seed bank. This seed bank would contain a back-up, or extra copy, of all the world's seeds. Smaller seed banks would still collect and keep local seeds. But they would also send copies of their seeds to the global bank.

    Scientists from the Global Crop Diversity Trust chose the cold, snowy mountains of Svalbard, Norway to build the global seed bank — the Svalbard Global Seed Vault (斯瓦尔巴全球种子库). Organizations, farmers, or local seed banks store their extra seeds there. And the people who place their seeds in the vault are the only people who can take them out. They pay to ship their seeds to Norway, but it does not cost them any money to store their seeds. The Global Crop Diversity Trust pays for this.

    Cary Fowler is a scientist who heads the Global Crop Diversity Trust. He said, “If the Seed Vault simply supplies seed banks with copies of seeds that those banks lost by accident, the Seed Vault will be worth more than it cost.”

    READY or not, the college application season has begun. There are two main kinds of early admissions programs: Early Action and Early Decision.

    Early Action is a great choice for the well-prepared student. Students apply early, and are allowed to apply under an Early Action program to as many colleges as they choose. The biggest advantage for students is that colleges let them know early – in most cases, before Jan 1. Roughly 15 percent of colleges and universities offer an Early Action option(选择). Oct 15 is now the first deadline for many colleges and universities. This movement toward earlier deadlines is especially popular in the Southeast, with many of the large public universities leading the way. North Carolina State University, the University of South Carolina and the University of Georgia all have an Oct 15 Early Action deadline.

    Early Decision is a promise that cannot be reversed. Students who are accepted must take back their other applications and should attend that school. Students are allowed to apply to just one school under an Early Decision program. Early Decision deadlines are in early November, with colleges letting students know by mid-December. Many students believe that they are more likely to be accepted if they apply for Early Decision, but it actually depends.

       In some cases there is big increase in students being accepted, and at other colleges it is not that big at all. Generally, the strongest students are applying early. Athletes and students with focused interests are encouraged to apply for Early Decision.

    Do you have cold feet in winter? But now if you wear a pair of Ugg boots, you won't be troubled by that.

    UGG means Australian Sheepskin Boots. UGG boots became popular among shearers(剪羊毛的人）in the 1920s. The shearers sheared the sheep and grabbed a bit of dead sheep, wrapped it around their feet and called them “Ugly Boots”. Good old Australian slang shortened Shearers Ugly Boots to UGG boots. Thus UGG Boots date back as far as the 1920s in Australia.

    Ugg boots became so popular because of the amazing amount of comfort they bring to the feel. The sheepskin is made incredibly soft so the boots are warm and comfortable. Ugg boots fed more like socks than shoes, yet they are tough enough for outdoor wear. The unique, wool fool-beds lake the shape of the natural edge of each wearer's feet, creating personalized arch (弓形) supports.

    Our ugg boots are handmade with Australian sheepskin of the highest quality by our factory of Ugg Original Pty Ltd.

    We can also wear ugg boots in cold weather or summer. In cold weather, the thick wool of ugg boots provides a preventing layer of warmth by trapping your body heat. In the heat of summer, the natural fibres of the wool will actually cool your feet by absorbing sweat. Ugg boots are made to be worn barefoot to maximize the cushioning and warmth provided by the sheepskin.

"Who does the cooking in your home?" I'm often asked by my colleagues. "My wife and I share it 50/50," I usually say without hesitation.

    It's a lie, of course. We're pretty much even（相等的）when it comes to the children and the elderly. But the paying of bills isn't 50/50-my wife pays all sorts of household expenses, so I never even have to set eyes on them. And the cooking isn't 50/50, either.

    The truth is that I am the cook. On my recent 40th birthday, I received the following gifts from my children: a new pot, two mini bottles of truffle oil, a decorative salad-dressing pourer, and a juice-making machine. For a moment I longed for something more manly, a cricket bat, perhaps, and then had to admit that all these things would be useful for me.

    It's not that my wife can't or doesn't like to cook (she makes delicious Welsh cakes). Nor has it always been this way. In the early years of our marriage I'd be relaxing with a glass of wine while my wife prepared for dinner after work.

But at some point that changed and I became the cook. Ten years with my wife gave me the rewards-I can throw together a roast, and I can make much foreign food. But I have truly become a monster(怪物) in the kitchen, unable to keep myself away from cooking. "You have to add Dijon to the sauce; it brings out the taste of the cheese," I volunteer, as my wife is cooking. "Quick, stir in the butter so the dish becomes delicious."

    Is it any wonder that my wife has given up coming into the kitchen while I find the whole process of chopping, mixing, and adding things deeply satisfying?

    Sure it's good to get along with your teacher because it makes the time you spend in the classroom more pleasant.

    And yes, it's good to get along with your teacher because in general it's smart to learn how to understand the different types of people you'll meet throughout your life.

    "But really there's one super-important reason why you should get along with your teacher. When you do learning bursts right open " says Evelyn Vuko a longtime teacher who writes an education column(专栏) called "Teacher Says" for the Washington Post newspaper.

    In fact, kids, who get along with their teachers not only learn more but they're more comfortable asking questions and getting extra help. This makes it easier to understand new material and do your best on tests. When you have this kind of relationship with a teacher he or she can be someone to turn to with problems such as problems with learning or school life such as bullying.

    As a kid in a primary or middle school you're at a wonderful stage in your life. You're like a sponge (海绵) able to absorb lots of new and exciting information. On top of that you're able to think about all this information in new ways. Your teacher knows that in most cases is very excited to be the person who's giving you all that material and helping you make it. Remember teachers are people too and they feel great if you're open to what they're teaching you. That's why they wanted to be teachers in the first place-to teach!

    Some kids may be able to learn in any situation whether they like the teacher or not. But most kids are sensitive to the way they get along with the teacher and if things aren't going well they won't learn as well and won't enjoy being in class.

    The huge T­rex (霸王龙) bends over a large triceratops (三角龙) lying on his side below. With its mouth open wide, the T­rex looks ready to kill the triceratops with a final bite to the triceratops's neck. The display will be found at the National Museum of Natural History.

    The museum has sought a huge T­rex skeleton (骨架) for many years. Before, it used a model of one. But museum director Kirk Johnson says that was never good enough. "It's been kind of deeply embarrassing to be the national museum and NOT have a T­rex," he said. The T­rex display is now the centerpiece of the museum's newest show, which will be available to the public on July 15.

    That T­rex, named Sue, was found in South Dakota. Officials at the museum built a special area for the skeleton. It includes a gift store of all things related to Sue. Sue even has her own Twitter account and a media presentation of her life story.

    In modern times, movies like "Jurassic Park (侏罗纪公园)" have helped grow dinosaur interest for a new generation of young fans. But such movies describe the T­rexes as mostly huge, stupid and dangerous animals, which are true threat in the fighting: quick, intelligent and aggressive hunters in groups.
