Your house may have an effect on your figure . Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off . You can make your environment work for you instead of against you . Here are some ways to turn your home into part of diet plan.

    Open the curtains and turn up the lights . Dark environments are more likely to encourage overeating , for people are often less self-conscious（难为情）when they're in poorly lit places-and so more likely to eat lots of food . If your home doesn't have enough window light, get more lamps and flood the place with brightness.

    Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room . Warm colors like yellow make food appear more appetizing , while cold colors make us feel less hungry . So when it's time to repaint, go blue.

    Don't forget the clock-or the radio. People who eat slowly tend to consume about 70 fewer calories（卡路里） per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes, And while you're at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.

    Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one ,total intake（摄入） jumps by 14 percent. And we'll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.

    MOOCs (Massive Open Online Courses) are free, but without tutoring, and are open to anyone, anywhere in the world. The courses are flexible — normally three to five hours of study a week — done at any time, short (5 to 10 weeks) and video-rich. They are also heavily dependent on crowd sourcing: you can discuss a course with fellow students through online forums, discussion boards and peer review. Students don't have to finish the courses, pass assessments or do assignments, but, if they do, they get a certification of participation.

    The Open University launched FutureLearn, the UK's answer to US platforms such as Coursera, EdX and Udacity, which have been offering MOOCs from top US universities for the past two years. The response has been incredible, with more than three million people registering worldwide. Meanwhile, in 2012, Edinburgh University became the first non-US institution to join Coursera's partnership, comprising 13 universities. “We already run 50 online master's degrees, so this was a logical expansion,” says Professor Jeff Haywood, Edinburgh's vice-principal. “It's an investment in teaching methods research. How am I going to teach introductory philosophy to 100,000 people? That's what I call educational R&D.” He adds “If you look ahead 10 years, you'd expect all students graduating to have taken some online courses, so you've got to research that. Our MOOCs are no more in competition with our degrees than a lifelong learning course because they don't carry credits.”

    Cooperation is key, Haywood stresses. It is far better to offer 20-30 courses in your own areas of expertise (专门技能) and let other institutions do likewise. Professor Mike Sharples, FutureLearn's academic lead, goes further: “We've tied the elements available before into a package of courses offered by leading universities worldwide on a new software platform, with a new way of promoting it and also a new social-learning teaching method. You won't just receive an exam, but be able to discuss and mark each other's assignments.”

    Bath University, one of more than 20 universities working with FutureLearn, launches its first course, Inside Cancer, next January, and regards MOOCs as a way of breaking down age barriers. “There's no reason why someone doing GCSEs should not look at our MOOCs and get quite a way through them, or someone at PhD level and beyond,” says Professor Bernie Morley, expert for learning and teaching.

    The Loss of Innocence

    Innocence is such a precious gift. It's explained as freedom from guilt or wrong doing. Just imagine never having to worry about anything and having a guilt free mind. Some people wish to save this kind of innocence from being lost from childhood to adulthood.

    What would the world be like if innocence were never lost? One way it would benefit humanity is the lack of hatred （仇恨）among the world. During youth, there may be an occasional argument, even a little physical fight, but nothing like firing a handgun at a fellow human being. And children are blind towards the racial differences of others. A kid will hang out with any other kid. It is the lack of innocence and the ignorance we learn from adults that influence children otherwise. Another benefit is the constant desire for fun and adventure. With very little if any time at all for fun，the adventurous mind is lost in time with the responsibilities placed upon adults. If innocence were kept alive, these ambitions would never depart from our lives.

    However, other people actually hate the idea of innocence lasting forever. They feel that the lack of organization and mental power of those with innocence would cause extremely destructive consequences to society in general. A large number of individuals would never have the urge to learn, work, and act upon the necessary needs for humanity to survive. Without a proper education which is usually provided by those who no longer live in a world of innocence, people would not have the desire to succeed, get a good job in life, or provide income for their families, which would hurt the lives of children.

    The lack of a good education and career would also harm the economy. As long as innocence is kept alive, no one would be terribly angered at the lack of effort people put out in the workplace, resulting in a strong decline in production and quality of needed goods.

    Maybe it is wrong in wanting to save innocence. It sure is a nice thought, though. Perhaps innocence was meant to be lost. It was God's will to make things the way they are, and there is a good purpose for everything. All that remains to be said about innocence is to enjoy it while it lasts.

    We all have found memories of taking a few lazy months off after the stress of A-levels. As we draw to the end of an academically and socially packed year, the idea of doing the same again is appealing.

    But after graduation, there will be few occasions when we can enjoy such extended holidays, free to do as we wish. So now that summer has arrived, let's take full advantage. It goes without saying that summer vacations are the perfect time to go traveling, especially if you avoid the pricey school holiday period.

    Tickets go up greatly when you turn 26, so make the most of cheaper rates while you're eligible. Finding a reliable company that won't cheat you is extremely important, as is discovering a program that appeals to your own interests. There are plenty of websites where you can see other people's recommendations.

    Of course for most of us, money is tight—but to avoid overspending you can combine employment and adventure. Hannah Warn, a psychology student at the University of Winchester, is spending her summer at Camp America, an increasingly popular venture where British students enjoy a good time on a summer camp.

    “Being thrown into something where I don't really know what to expect is exciting.” she says.“It gives me a chance to experience being away from home in a different way.”

    Those with a talent for languages might also consider working abroad as an au pair. The work may be challenging, but it's a chance to involve yourself in a new culture while your employer pays most of the bill.

    If you have an idea about the sort of career you'd like, getting work experience is wise. In many careers, graduating with only your degree to show for your three or four years just won't make it. Send applications off early and to as many places as possible. Make sure you take a well-earned break this summer.

    When many people are worried that there are no more heroes in the modern times, two university students who lost their lives to rescue drowning children have shown that heroes still exist (存在).

    According to the Inner Mongolia Morning Post. the tragedy (悲剧) occurred on the afternoon .December 14,2002 when three school students skating on a frozen lake in Qingcheng Park in Hohhot fell through the ice into the freezing water. More than 20 university students who happened to be near the Spot immediately went to the rescue of the children. Two children were quickly rescued, but the third died. The child's body was not found for three hours. Two of the rescuers, Liu Ye and had Longbiao, also died of cold and exhaustion. The body of Hao who took the lead in jumping into the lake was not found until the next day. A student who was unwilling to tell his name said he and his Classmates from the local college were taking photos at the lake. When they heard the children's criestor help, they went to the ice hole hand in hand to rescue the children. But the ice kept breaking, causing most of them to fall into the icy water.

    Local residents held mourning ceremonies (祭莫仪式) at the lake. Eight of the students were seriously affected by the freezing water and were being kept in hospital for further observation, but their lives were no longer in danger.

    As our closest neighbor in space, the moon has been the subject of popular myths, songs and poems since ancient times. And it has no less fascinated scientists. But even after centuries of research many questions remain to be answered about Earth's only satellite. Perhaps the Chang'e-4 lunar probe will be able to reveal more of its secrets.

    On Dec 8, the probe lifted off from Xichang Satellite Launch Center in Sichuan Province. It is the first probe to the far side of moon.

    The Earth's gravity slows the moon's rotation, matching it to the speed of its orbit. Thus, the far side of the moon is always dark and has never been seen. It's this sense of the unknown that makes the far side of the moon such an interesting place for scientific and space exploration.

Long exposed to solar winds, the far side may have the special soil and minerals in its upper mantle(地幔).For this reason, Chang'e-4 will study the effect of solar winds on the lunar surface and any minerals found beneath the spacecraft.

    Chang'e-4 is also carrying flower seeds and potato and silkworm eggs to see whether life is possible on the moon. If it is, then the moon will become a more likely destination for space travel in the future. However, due to communication problems, exploration of the dark side will not be easy.

    As the far side is blocked off from us, radio noise coming off Earth is also blocked. This is why China launched the relay satellite Queqiao in May—so that communication between Earth and the probe could go ahead. Power supply will also be a challenge to the mission.

    Chang'e-4 gets energy from the sun through its solar panels. However, a lunar day has the length of 28 Earth days. This means that the probe will need to orbit the moon for over 20 days to be in a position to be able to land in moon daylight and so use its solar panels.

    According to Xinhua, if everything goes well, the satellite will land on the far side on Jan 2.

    The New York Times described the journey as “groundbreaking”, and wrote that it will “give clues to the history and development of the moon”.
