Far from the land of Antarctica (南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.

    For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.

    Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish's blood and measured its freezing point.

The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to

-2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.

    The scientists' next research job was clear: Find out what in the fish's blood kept it from freezing. Their search led to some really strange thing made up of a protein (蛋白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.

    Study showed that it is an unusual kind of protein. It has many small sugar molecules（分子）held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.

    Be a Green Child

    What does it mean to be green? “Green” is more than just a color.{#blank#}1{#/blank#} Why green? Plants are green, and without them the Earth wouldn't be such a lovely home for us human beings. What can we do? Here's a four-step guide to being green.

    Reduce It!

    {#blank#}2{#/blank#} For instance, a shorter shower means you used less water and less fuel since your house uses to run the heater that warmed up the water.

    Reuse It!

    Sometimes people call ours a “throwaway society”. It means that we're a little to willing to throw away old stuff (东西) and buy new stuff.{#blank#}3{#/blank#}

    For instance, if your baby brother becomes older and loses interest in his plastic basketball hoop (篮圈), why not give it to another family who has a little kid?

    Recycle It!

    Recycling has never been easier. Many communities will pick it up right in front of your house and some towns even require it. Recycled goods go to a recycling center, where they can be turned into new cans, bottles, and paper.

    Enjoy It!

    It's true that rubbish and pollution are problems, but the Earth remains a huge and beautiful place that's ready for you to explore.{#blank#}4{#/blank#} Go for a hike, visit local nature centers and gardens, and climb up mountains.

    But before you travel the globe, take a look at your own backyard. Is there a spot where you could plant a tree or put in a little fruit or vegetable garden? {#blank#}5{#/blank#}

A. It also means taking special steps to protect the environment.

B. Many times, even if you no longer need something, someone else just might.

C. You can start locally by visiting the naturally beautiful spots in your city.

D. Turn off the water when you're brushing your teeth.

E. Get out there and get your hands dirty.

F. You can watch with pride as your tree takes root and your garden plants grow.

G. When you use less of something, you do a good thing for the Earth.

    Good Morning Britain's Susanna Reid is used to grilling guests on the sofa every morning, but she is cooking up a storm in her latest role — showing families how to prepare delicious and nutritious meals on a tight budget.

    In Save Money: Good Food, she visits a different home each week and with the help of chef Matt Tebbutt offers top tips on how to reduce food waste, while preparing recipes for under £5 per family a day. And the Good Morning Britain presenter says she's been able to put a lot of what she's learned into practice in her own home, preparing meals for sons, Sam, 14, Finn, 13, and Jack, 11.

    "We love Mexican churros, so I buy them on my phone from my local Mexican takeaway restaurant," she explains. "I pay £5 for a portion(一份), but Matt makes them for 26p a portion, because they are flour, water, sugar and oil. Everybody can buy takeaway food, but sometimes we're not aware how cheaply we can make this food ourselves. "

    The eight-part series(系列节自), Save Money: Good Food, follows in the footsteps of ITV's Save Money: GoodHealth, which gave viewers advice on how to get value from the vast range of health products on the market.

    With food our biggest weekly household expense, Susanna and Matt spend time with a different family each week. In tonight's Easter special they come to the aid of a family in need of some delicious inspiration on a budget. The team transforms the family's long weekend of celebration with less expensive but still tasty recipes.

    We know that our pet dogs and cats can recognize our faces, but our pet fish? A team of scientists from the UK and Australia have discovered that archer-fish(喷水鱼) can distinguish human faces!

    This marks the first time that a species of fish has shown such an ability. Such abilities have been previously shown in birds, but unlike fish, they have been proven to possess structures similar to the neocortex(大脑新皮层), the researchers added.

    "Being able to distinguish between a large number of human faces is a surprisingly difficult task," Dr Newport said, "mainly due to the fact that all human faces share the same basic features."

    During their experiments, Dr Newport and her colleagues presented archerfish with two images of human faces, and trained them to choose one by spitting jets(喷射流)of water at that picture. Next, the fish were presented with the familiar face and several that were unfamiliar, and were able to correctly pick the one that they had been trained to recognize, even when features such as head shape and color were removed from the selected pictures.

    In the first experiment, the archerfish were tasked with picking the previously learned face from a group of 44 new ones, which they did with 81 percent accuracy. In the second, the researchers decided to make things a little harder. They took the pictures and made them black and white and evened out (使平均) the head shapes. You would think that would throw the fish for a loop. But no, they were able to pick the familiar face even then—and with more accuracy: 86%!

    "Fish have a simpler brain than humans and entirely lack the section of the brain that humans use for recognizing faces. Despite this, fish may still be capable of finding the face they are trained to recognize," Dr Newport said. "The fact that archerfish can learn this task suggests that complicated brains are not necessarily needed to recognize human faces."

    The Spanish sculptor Isaac Cordal sees the city as his playground. He specializes in miniature, a street art often representing a social commentary as a critical observation on capitalism, power and so on.

    Cordal first models the sculptures in clay then reproduces them in cement(水泥)about 15cm in height.

    “As a material, cement seems very symbolic because it is one of our most recognizable footprints against nature.” he says. “Today we have been too used to cement city habitat.”

    For several years he's been working on the project, Cement Eclipses, referring to the state when a building covers the sun: “It's a critical reflection on the idea of progress.”

    These tiny cement figures have appeared in cities across Europe, found sitting on top of bus shelters or drowning in the grass land of the big city. “The street became a perfect setting in which I could find enough landscapes for them. Due to their small size and color, they go really well into the urban environment. They even normally go unseen by passersby. I'm very interested in that moment of surprise when someone accidentally discovers them.” he says.

    “Nowadays there is a fear of not being seen in the public area, so everything is always big and bold. We become a product of this and do not focus in as much. I think it is good to pay attention to small details. My work is a reward for those who do and it allows us to understand and change the world we have created in a different angle.”Cordal says.

    There are many programs for high school students today that help lonely teenagers deal with loneliness. However, loneliness is not only a problem for teens but also an important and rarely acknowledged one in the elderly.

    In Britain, Tracey Crouch was appointed to be the first Minister of Loneliness in order to address the problems caused by loneliness. This is the first time such a position has been created.

    In Britain, there are around 9 million people who say they are lonely frequently. In Germany, a study conducted by Ruhr University Bochum found that 20 percent of people over the age of 85 felt lonely, and 14 percent of those between age 45 and 65 felt socially lonely. In the United States, more than 25 percent of the population live alone, more than 50 percent are unmarried.

    Loneliness is generally associated with heart disease  overweight, and anxiety. Additionally, the stress from loneliness can cause your cells to change on a molecular (分子) level that reduces its abilities to defend your body against diseases. In fact, doctors believe having feelings of loneliness is equivalent to smoking 15 cigarettes per day in regard to its effect on health!

    In Britain, the new Minister of Loneliness will help introduce government policies on the problem and fund a charity—an organization for helping people in need, to devote their efforts towards aiding loneliness. There are charities that link lonely seniors to high school students in order to give them a line of communication whenever they feel lonely!

    The possibilities for the new Minister of Loneliness are endless. For example, she can provide education services to household businesses so that they can identify lonely customers if they see one. Loneliness fits into the category of being a social problem that must be monitored by the entire community in order to help those in need. Therefore, government involvement in medical services and care for seniors and others is vital for happy seniors.
