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 your 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 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 30 minutes. And while you're at it, actually sit down to eat. If you need some help slowing down, turning on relaxing music. It makes you less likely to rush through a meal.

Downsize the dishes. Big serving bowls and plants can easily makes 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.

    Computers have beaten human world champions at chess and, earlier this year, the board game Go. So far, though, they have struggled at the card table. So we challenged one AI to a game.

Why is poker(扑克)so difficult? Chess and Go are “information complete” games where all players can see all the relevant information. In poker, other players' cards are hidden, making it an “information incomplete” game. Players have to guess opponents' hands from their actions—-tricky for computers. Poker has become a new benchmark for AI research. Solving poker could lead to many breakthroughs, from cyber security to driverless cars.

    Scientists believe it is only a matter of time before AI once again vanquishes humans, hence our human-machine match comes up in a game of Texas Hold's Em Limit Poker. The AI was developed by Johannes Heinrich, researcher studying machine learning at UCL. It combines two techniques: neural(神经的)networks and reinforcement learning(强化学习).

    Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better.

    Mr Heinrich told Sky News: “Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations.”

    After two hours of quite defensive play, from the computer at least, we called it a draw.

    That the US stock market dropped sharply immediately after the US government put forward the proposal on Tuesday to tighten the control on exports of various artificial intelligence technologies indicates what the market thinks of the move.

    Multi-national corporations have led the way in the profound compressing(压缩) of time and space that has flattened and changed the world over the last couple of decades, and the overwhelming majority of international technological transfers have been conducted among multi-national companies in pursuit of profits.

    Thus the proposal the US government put forward on Tuesday to tighten the control to "avoid negatively impacting US leadership in the science, technology, engineering and manufacturing sector" is being viewed not only as a brake on the US economy but also as a barrier to maintaining that leadership since it will reduce cooperation with the rest of the world and shrink the market for US companies preventing them from investing research and development.

    The bigger its market, the more profits a technology company can earn, and the more money it then has to invest in developing even more advanced technologies. This is as true for US companies as it is for others.

    Behind the proposal is the narrow-mindedness of policymakers in the US administration, who choose to ignore the fact that the United States would not have become the world leader in science and technology if it had kept its doors closed.

    If such controls are intended to contain China's development, they will certainly fail.

    It is true that China has a lot to do to catch up with the US and other developed countries. Yet it has made great steps forward by opening its doors and cooperating with other economies.

    As it opens its door wider, it will have even more opportunities to cooperate with other countries in science and technology.

The de-materialization of economic activities — with economic output and income generation increasingly reliant on information rather than inputs of raw materials — only increases the need for cooperative agreements and a cross-disciplinary approach to increase the capabilities of AI and advance its application.

    By trying to enforce and exploit an invented-here ideal that is untenable, the US will undoubtedly lose the leadership in science and technology gradually to which it has become accustomed, and prevent the progress of both humans and machines.

    If American waterways had ever been voted on the yearbook, the Buffalo River could easily have been named Ugliest. It could be hard to find hope there. It took decades for public perception of the river to shift. But activist citizens, who collaborated with industry, government, and environment groups never gave up on their polluted river—the Buffalo River gradually went from being considered a lost cause to a place worth fighting for. And by now the cleaned—up water is one of Buffalo's biggest attractions.

    By the 1960s, the river was seen as one of the worst sources of pollution pouring into the Great Lakes. The Buffalo River had caught fire many times. The surface had an oily layer, and any fish caught there were not eatable.

    The waterway's fate started shifting in the mid-1960s. Stanley Spisiak was a local Polish—American jeweler by day, but by evening he was the kind of guy who'd chase down dumpers(垃圾车)he spotted on the Buffalo River. By 1966 he found himself winning the National Wildlife Federation's “Water Conservationist of the Year” award. And before long he got a nickname:“Mr. Buffalo River.” But there was only so much he could do—the river was still declared biologically dead in 1969.

    Jill Spisiak Jedlicka is his great-grandniece. She picks up where he left off by directing the river's protector organization, Buffalo Niagara Waterkeeper. Professor Schneekloth and seven friends founded the organization as an all-volunteer nonprofit in 1989, after organizing the first river cleanup that year. Today the group employs 27 full-time workers and has helped oversee the Buffalo River's $100 million restoration.

    So far, the Buffalo River's water quality has restored, but it is still an ongoing issue, as sewage(污水)can overflow into the river after storms. Habitat restoration continues as well; fish and plantings are still being sampled to measure how well it's gone.

    Dr. Michael Prager, a leading Botox expert, said that a growing number of women are developing something called "computer face". He also mentioned that professionals who worked long hours in front of a screen were ending up with saggy jowls(颚骨下垂),"turkey neck" and deep-set wrinkles(皱纹)on their forehead and around their eyes.

    The Botox expert said that, of all his clients, office workers were most likely to show premature (过早的)signs of aging. " If you are one of the unfortunate people who frown(皱眉)while you are concentrating on the screen then, over time, you will inevitably(不可避免地)end up with frown lines.'' Dr. Prager said. "What is perhaps more surprising is the number of women with saggy jowls because they are sitting in one position for so long. If you spend most of the time looking down then the neck muscles shorten and go saggy, eventually giving you a second neck."

    Dr. Prager, who has a practice near Harley Street in London, said he encourages his clients to put a mirror next to their computer so they can see if they are frowning at the screen. "When people are stressed or thinking hard about something, then they will often put on a grumpy(脾气暴躁的)face' without even knowing what they are doing. When my clients put a mirror next to their desk, they are often shocked by the angry, frowning face which stares back at them."

    He said, "The women I am seeing at the moment have only been using computers at work for the last decade or so. But women in their 20s have grown up with them and use them for every single task. I think the problem is going to become much, much worse. In another ten years, they could be looking quite awful."

    Dr. Prager said there were several simple steps which could avoid "computer face" such as regular screen breaks and stretching the neck muscles. And, of course, there was always Botox(肉毒杆菌). He said that, after a couple of sessions of Botox, the habit of "grumpy face" could be broken.

A donation letter is what you write to a person you expect, who will give away some of his money to support your good cause. Good as the cause may be, it is hard to make a person part with his hard-earned money. It takes some really great writing skills to write such a letter.

The donation letter for charity isn't exactly a formal letter for business communication. You need to take a casual tone. Make sure that you know the name of the recipient (收信人) to sound more like a friendly gesture. The language too should not be extremely serious and should be slightly informal, which can make your recipient willing to believe you.

Make sure that you include all the details regarding your program, your funds required, and your plan in the letter. The most important thing is to mention how someone stands to benefit because of the recipient's contribution. Talk about how many lives your charity fund has been able to change and how many more you wish to change further. This may touch the reader and talk him into making a donation towards your cause. Include the amount which you expect the recipient to donate, within your letter.

A typical donation letter is often divided into four paragraphs. The first paragraph will be an introduction to your organization, like what you do, how long you have been running, and your achievements. The second paragraph will give more details regarding your current goals that you're trying to reach. In the third paragraph you use a more direct method here, asking politely for any help. Keep it short and clear. The final paragraph is your conclusion, where you tell exactly how the help received would be put into good use. Add a "thank you" for any and all help received.
