The weight-loss world is full of assertions①, rarely proved, that some pill can help you “burn calories while you sleep.” But a recent Dutch study reports that it can be done – simply by eating more lean protein②.
Researchers report for the first time that consuming nearly a third of daily calories as lean protein – for example, lean meats without the skin – speeds up a person’s metabolism③ during sleep and that higher protein intake increases the burning of calories and fat during the day. Plus, when the study’s participants, who were all women of healthy weight, ate more protein, they felt fuller, more satisfied and less hungry than when they consumed a diet with the amount of protein, about 10 percent of calories.
The findings suggest that adding lean protein to your daily food “enables you to reach the same level of satiety④that you are used to with about 80 percent of your normal energy intake,” notes Margriet Westerterp-Plantenga. “That means you can eat about 20 percent less and still have the same satiety.”
What gives protein its caloric edge? It’s more difficult for the body to metabolize protein than either fat or carbohydrates⑤. The body also doesn’t store protein as efficiently as it does carbohydrates or fat. So protein is more likely to be burned and that in turn requires more oxygen and helps you feel satisfied in the hours after eating.
But the latest findings don’t mean it’s time to dust off those high-protein diet books. The current study limited fat to about 30 percent of daily calories, and included 40 percent of calories as healthy carbohydrates, including fruit and vegetables. For example, lunch included bread, soy milk, fruit yogurt, tuna in water, tomatoes, cucumbers, feta cheese and salad dressing.

Looking for a low-cost path to self-knowledge? A way to mine your subconscious①for clues to your motivations, desires and fears? No need to have years of treatment or analysis. Just look to your dreams.
“You can ignore your dreams, but you are really doing harm to yourself,” says Lauri Quinn Loewenberg. “If so, you’re letting red flags pass you by, letting great ideas pass you by.”
Some sleep researchers believe dreams are more directly related to our moods and emotions and can serve as tools to self-understanding. Dreams occur during the REM (rapid eye movement) cycles of sleep each night. For adults, that means about every 90 minutes. The first period of REM sleep may be short, 5 to 10 minutes, followed by longer periods, finally reaching an hour or more in the fourth or fifth period.
When people are dreaming, brain scans show a lot of activities. The brain is online during dreams. The experiences you have during the day are connected during dream sleep. People we know or experiences we’ve had at different times in our lives may be different in the same dream.
AmyBeth Gilstrap has had the same recurring② dream that annoyed her since Hurricane Katrina drove her and her daughter and friends out of New Orleans. Ms. Gilstrap says, “It is always spies. My job is to get people to some place.” She’s certain the dream is related to her effort in the hurricane to help several families leave. Sometimes her cats also are part of that dream. That’s because she went back into New Orleans, before it was allowed, to rescue her cats.
Today, through brain scans scientists have known that the parts of the brain that control emotion and long-term memory are active during REM sleep.

A typical① Chinese Internet user is a young male who prefers instant messaging to e-mail, seldom makes online purchases② and favors news, music and games sites. According to a study, about two-thirds of survey participants③ use the Internet for news — often entertainment-related — or for online games. About half download music and movies.
They also tend to prefer instant messaging to e-mail, and they are depending on the Internet more frequently than before to communicate with others who have the same professions, hobbies and political interests. Online purchases still remain unpopular in China. Three-quarters of users surveyed have never bought anything over the Internet, and only 10 percent make purchases even once a month. Among those who do buy online, most pay for entertainment while others buy phone cards, or computer hardware or software.
“Many people don’t trust the quality of goods bought online,” Guo said Wednesday. “If they buy it in a store and don’t like it, they can easily bring it back.”
The survey was done in five major cities: Beijing, Shanghai, Guangzhou, Chengdu and Changsha. Results do not necessarily project countrywide because Internet use in rural areas is lower than in cities. Guo describes the typical netizen in the five cities surveyed as young, male, richer and more highly educated. Males make up two-thirds of the Internet community, and more than 80 percent of users are under 24. Among people ages 25 to 29, 60 percent to 80 percent go online.
China has more than 100 million people online, second in the world to the United States.

When you turn on the radio, you hear an advertisement. When you watch television, you hear and see an advertisement. If you turn the pages of a newspaper or magazine, again you find an advertisement. If you walk down the street, you see one advertising board after another. All day, every day, people who want to sell you something compete to catch your attention. As a result, advertisements are almost everywhere.
In the West, advertisements are the fuel that makes mass media work. Many TV stations, newspapers, magazines, radio stations are privately owned. The government does not give them money. So where does the money come from? From advertisements. Without advertisements, there would not be these private businesses.
Have you ever asked yourself what advertising is? Through the years, people have given different answers to the question. For some time it was felt that advertising was a means of keeping your name before the public? and some people thought that advertising was “truth well told.” Now more and more people describe it in this way: Advertising is the paid, non-personal, and usually persuasive(有说服力的) description of goods, services and ideas by identified sponsors(明确的出资者) through various media.
First, advertising is usually paid for. Various sponsors pay for the advertisements we see, read, and hear over the various media. Second, advertising is non-personal. It is not face to face communication. Although you may feel that a message in a certain advertisement is aimed directly at you, in reality, it is directed at large groups of people. Third, advertising is usually persuasive. Directly or indirectly it tells people to do something. All advertisements try to make people believe that the product, idea, or service advertised can do good to them. Fourth, the sponsor of the advertisement must be identified. From the advertisement, we can see if the sponsor is a company, or an organization, or an individual. Fifth, advertising reaches us through traditional and nontraditional mass media. Included in the traditional media are newspapers, magazines, radio, television, and films. Nontraditional media include the mail, matchbox covers, and billboards.

He could have been president of Israel or played violin at Carnegie Hall, but he was too busy thinking. His thinking on God, love and the meaning of life graces our greeting cards and day-timers.
Fifty years after his death, his shock（乱蓬蓬的一堆）of white hair and hanging moustache still symbolize genius. Einstein remains the foremost scientist of the modern time. Looking back 2,400 years, only Newton ,Galileo and Aristotle were his equals.
Around the world , universities and academies（研究院）are celebrating the 100th anniversary of Einstein’s “miracle year” when he published five scientific papers in 1905 that basically changed our grasp of space, time ,light and matter. Only he could top himself about a decade later with his theory of relativity.
Born in the age of horse-drawn carriages, his ideas launched a technological revolution that has made more changes in a century than in the previous two thousand years. Computers, satellites, telecommunications, lasers, televisions and nuclear power all owe their invention to ways in which Einstein exposed a stranger and more complicated reality underneath the world.
He escaped Hitler’s Germany and devoted the rest of his life to human rights and peace with an authority unmatched by any scientist today, or even most politicians and religious leaders. He spoke out against fascism（法西斯主义）and racial prejudice. His FBI (美国联邦调查局)file ran 1,400 pages.
His letters expose a disorderly personal life ─ married twice and indifferent toward his children while absorbed in physics. Yet he charmed lovers and admirers with poetry and sailboat outings. Friends and neighbors fiercely protected his privacy.

A．had the gift for politics and music

B．had run for president before he worked at his research
