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 satiety④ that 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.

A. there’re few studies on weight-loss in the world

A. it can slow down a person’s metabolism B. it’s difficult for the body to metabolize
C. it will not make you feel full D. it’s easy to be stored in the body
3. The underlined phrase “dust off” in the last paragraph means ______.
A. get rid of B. put away C. get ready to rewrite D. get ready to reuse
4. The passage is mainly to tell readers ______.
A. there is a good diet for weight-losers

Tobacco is the second major cause of death in the world. It is responsible for the death of one in ten adults worldwide (about 5 million deaths each year). If current smoking patterns continue, it will cause some 10 million deaths each year by 2020. Half the people that smoke today, that is about 650 million people, will eventually be killed by tobacco.
Tobacco is the fourth most common risk factor for disease worldwide. The economic costs of tobacco use are equally devastating (破坏性的). In addition to the high public health costs of treating tobacco-caused diseases, tobacco kills people at the height of their productivity, depriving (剥夺) families of breadwinners(养家糊口的人) and nations of a healthy workforce. Tobacco users are also less productive while they are alive due to increased sickness. A 1994 report estimated that the use of tobacco resulted in an annual global net loss of 200 thousand million US dollars, a third of this loss being in developing countries.
Tobacco and poverty are closely linked. Many studies have shown that in the poorest households in some low-income countries as much as 10% of total household expenditure is on tobacco. This means that these families have less money to spend on basic items such as food, education and health care. It contributes to a higher illiteracy rate, since money that could have been used for education is spent on tobacco instead.
Which of the following statements is TRUE according to the first paragraph?
A. Smoking causes 10 percent of the deaths worldwide.
B. About 10 million people will die from smoking each year by 2020.
C. Half the people in the world will be killed by smoking.
D. Roughly there are 1,300 million smokers nowadays.
According to the passage, tobacco affects a family in the following aspects EXCEPT _______.
A. relationship B. education
C. health D. economy
The text uses a lot of figures to _____.
A. show we shouldn’t smoke too much
B. tell people exactly the number
C. warn people of the harm of smoking
D. indicate the writer had a careful investigation
The underlined word “illiteracy” in the last paragraph means ____.
A. great intelligence B. good education
C. bad behaviors D. inability to read or write
What is the best title of the passage?
A. Tobacco Should Be Banned.
B. Why Is Tobacco a Major Threat to Public Health.
C. Tobacco and Poverty Go Hand in Hand.
D. Tobacco May Cause Death.

Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.
Any owner will tell you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people— half of them pet owners —while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed (放松)around pets, says Allen, who thinks it may be because pets don't judge.
A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about 11 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more exercise overall-mostly with their dogs - and found it worth doing.

Burn Calories in Your Sleep?
The weight-loss world is full of assertions（断言）, 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 protein（无脂肪蛋白质）.
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 metabolism（新陈代谢） 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 satiety（过饱）that 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 carbohydrates（糖类）. 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.
