No one knows how much money Dr. Lyle Tullis gave away to students. I was his colleague for nearly a decade and I never stopped being amazed at his generosity. Our college has a program of providing cross-cultural experiences for students. Lots of students take advantage of summer experience oversea. I discovered that no group left for overseas with some of its members receiving financial help from Dr. Tullis.

    It wasn't that he made a lot of money. For one thing, he taught in a church-run school. There, his salary was half of what those people earned in a tax-supported school.

    Other colleagues occasionally complained about the low pay. Not Lyle Tullis. Occasionally some professors would leave our campus for a better-paid position. They told me they did so because, with better pay, they could provide for their families.

    The size of Lyle Tullis' paycheck never seemed to be the most important thing to him. I realized that one day when I was thanking him for helping a student, his eyes shone as he said to me, “I've got so much money that I don't know what to do with it. So, I just give it away.”

    Most people wouldn't have thought that way. Dr. Tullis drove one of the oldest cars on campus. It was even older than almost any of the students' cars. His home, while comfortable, was not fancy at all. But Lyle Tullis lived with the feeling that he had so much money that he needed to give it away.

    He was one of the favorite on campus. Cynics(愤世嫉俗者) might say he bought fame. But they would misunderstand. Lyle wanted to devote his life, all of it, to helping others.

    New Zealand will create one of the largest marine protected areas in the world, spanning an area of 620,000 sq km.

    The Kermadec Ocean Sanctuary (保护区) will be one of the world's most significant fully protected ecosystems, the prime minister of New Zealand, John Key, told the UN General Assembly in New York.

    The sanctuary is in the South Pacific Ocean, about 1,000 km north-east of New Zealand, and expands a marine reserve that surrounds some small islands. The area is considered important in terms of biodiversity, featuring nearly 35 species of whales and dolphins, 150 types of fish and three of the world's seven sea turtle species. It is also geologically significant, including the world's longest chain of underwater volcanoes and the second deepest ocean trench, into 10 km underwater — deeper than Mount Everest's height. The scale of the sanctuary will dwarf (矮化) any previous New Zealand's protected area, spanning twice the size of the country's mainland. It will cover 15% of New Zealand's economic zone.

    Commercial and recreational fishing will be completely banned, as will oil, gas and mineral prospecting (勘探), exploration and mining. Key's government aims to pass legislation establishing the sanctuary next year.

    "The sanctuary is a world-class, unspoiled marine environment and New Zealand is proud to protect it for future generations,"Key said."New Zealanders value our coasts and oceans, which are an important part of our culture, economy and environment and we are committed to managing them sustainably. Creating protected areas will support not only our own fisheries, but those of our Pacific neighbors, adding to New Zealand's efforts to help grow Pacific economies through the responsible management of their ocean resources."

    Nick Smith, New Zealand's environment minister, said the sanctuary might impose a cost upon the mining industry but that it is important to protect the ocean before exploration takes place."New Zealand needs to use its vast ocean resources for jobs and exports in industries like fishing, aquaculture, minerals and energy, but we also need to set aside special areas where nature comes first and marine life is fully protected,"Smith said.

    New Zealand will monitor the area via its navy and satellite technology. The Kermadec region will join three other key areas in the Pacific protected by the US, the UK and Australia.

    Matt Rand, director of the Pew Charitable Trusts' Global Ocean Legacy (遗产) campaign, welcomed Key's announcement."New Zealand will create the gold standard of conservation areas in the sanctuary, preserving one of the few ly unspoiled areas of ocean on Earth,"he said."This commitment is an exciting step toward meeting global goals to safeguard at least 30% of the ocean through fully protected marine reserves."

    Chocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for” or say “death by chocolate”. Now they should bite their tongues! Evidence is showing that some kinds of chocolate are actually good for you in the following ways:

    A happier heart

    Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart．Studies have shown heart benefits from increased blood flow. These benefits are the result of coca's chemicals, which seem to prevent both cell damage and inflammation (炎症)．

    Better blood pressure

    If yours is high, chocolate may help. Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly.

    Muscle magic

    Chocolate milk may help you recover after a hard workout (锻炼). In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks.

    Better for your skin

    German researchers gave 24 women a half-cup of special cocoa every day. After three months, the women's skin was moister (滑润的) and smoother. The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance．

Brain gains

    It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain．

    Do you ever pull your phone out of your pocket, thinking it is vibrating(振动), only to find that it isn't? This phenomenon, which scientists call "phantom(幻觉的)phone vibration", is very common. Around 80% of people surveyed say they have imagined their phones vibrating when they were actually still.

    So, what leads to this universal behavior? According to the BBC, the explanation lies in your brainˈs ability to discover signals from the outside world. When your phone is in your pocket, there are two possible states: it is either vibrating or not. Meanwhile, you also have two possible states of mind: the judgment that the phone is vibrating, or that it isn't. Ideally, you match the four states correctly.

However, sometimes your brain decides that the results of missing a call are more serious than a "false alarm". Therefore, you become more sensitive(敏感的) to vibrations so that you don't miss anything. This is just like the fire alarm in your home—it can be annoying when it goes off in response to just a tiny bit of smoke. But that's a small price to pay compared to a fire really breaking out because the alarm fails to alert you. Now, you might still ask: why can't our brains just make every judgment correctly without being too sensitive to false signals? The answer is that your brain bears a heavy burden every day. "You get a large amount of sensory(感觉的) information that's coming from your eyes, ears and skin, and you can't deal with all that information all the time, "Michael Rothberg, a researcher at Baystate Medical Center in Springfield, US, told Live Science.

    For example, the rustling(沙沙声)of clothing or the growling(咕咕声)of your stomach may both lead your brain to believe that they come from the vibration of your phone-it is like trying to hear your name being called in a noisy room.

    So, perhaps you should just check your phone whenever you think it's vibrating. It's not too much trouble to do that, is it?

    Nasr Majid started hunting this fall at Blackwater National Wildlife Refuge (保护区)on the Eastern Shore of Maryland in USA, He's one of the relatively few new hunters who officials hope will help stop a nearly four-decade decline nationally in what has become a hobby for fewer than 5 percent of Americans.

    Natural resources and wildlife, officials in Maryland are encouraging hunting of deer, turkeys and some other wild animals, which is believed to be good for the environment. Without hunting, they say, sika deer will overpopulate the wildlife refuge and they'll overeat the bushes and other plants that provide important habitat for birds. On the western shore of the Chesapeake Bay, hunting is also important to prevent the spread of diseases such as Lyme.

    In many families, the hunting tradition has been handed down for generations^ But as longtime sportsmen age and children lose interest, the number of hunters in the United States fell by 2 million, from 2011 to 2018, to about 11 million.

    "Everything is changing. Kids are growing up in front of video games and computers instead of going hunting." said Chris Markin, a hunting specialist for the state natural resources department. "Adults usually focus on working and providing for their families. Those pressures are preventing many other potential hunters from going out, and from raising the next generation of hunters."

    To avoid such a decline, a new approach is needed. Government agencies and nonprofit groups are now launching mentoring (指导) programs to train more hunters, which not only helps preserve an industry and a culture but also means more protection for wildlife and their habitats through deer population control and investment.

    Luckily, there are those still eager to learn, like Majid. He was just looking for an outdoor hobby he could share with his children when he came across the mentors-hip program. Now, he feels capable of hunting on his own, but also has someone he can text with questions that pop up. His new pastime has already paid off for him—on his second hunt with his mentor, in the last minutes of daylight, he bagged his first deer.

It's necessary to revise(复习) after lessons so that you can really understand, remember and use what you have learned. It is also important to revise before exams. {#blank#}1{#/blank#}. 

    Find Your Place. To revise for an exam, you must first find a quiet and relaxing environment. {#blank#}2{#/blank#} It should also be a place where you will not be disturbed.

    Take Your Time. It's a good idea to make revising part of your weekly routine. The best way to do this is to revise every school day. {#blank#}3{#/blank#} Make sure that you study for no more than two hours every time, and that you take a little rest every half hour or so. This will keep you fresh and able to take in information.

    Stay Organized. {#blank#}4{#/blank#} If you are taking notes, organize them by subject, topic and date. That way when you have an exam, you can easily find the right notes to study to help you prepare.

 {#blank#}5{#/blank#} At the end of every revision, review your notes carefully to check that you have understood what you have learned. You may also consider writing out revision cards. You can then use these as summary of the subjects that you have learned.
