Dieters' who eat meals high in protein might lose a bit more weight than those who get less protein and more carbohydrates (碳水化合物)一all other things being equal, a new analysis of past studies suggests. Researchers found that over an average of 12 weeks, people having a high一protein diet lost about 1.8 extra pounds, and more body fat, than those having a standard-protein diet.
Wycherley from the University of South" Australia in Adelaide, the lead author on the study says it’s possible that the body may spend more energy and bum more calories while dealing with protein, compared to carbohydrates. Another explanation for the link his team observed is that eating protein helps preserve muscle mass and muscle mass bums more calories, even when the body is resting, than other types of mass. He says people in the studies tend to get protein from a variety of animal and vegetable sources. Vegetable sources of protein include beans.
It is not obvious why a higher protein-to-carbohydrate ratio might help people lose more pounds——and one obesity researcher not involved in the new analysis questioned whether the trials were strong enough to make that conclusion. “The studies are generally far too short to tell effect,” Dr. James Levine from the Mayo Clinic in Scottsdale, Arizona, told Reuters Health in an e-mail. But given the limitations of the present evidence, Levine said, “It makes no real difference which of the weight-loss ways one chooses.”
1.According to Wycherley’s analysis, dieters should take in more ______.
A. fat B. carbohydrates C. protein D. calories
2.What can we learn from the studies?
A. It bums more calories to deal with carbohydrates.
B. Protein helps keep muscle mass which bums calories.
C. Vegetables contain more protein than animals.
D. No more calories are burned while the body is resting.
3.What is Levine’s attitude towards the conclusion of the studies?
A. Doubtful. B. Supportive. C. Curious. D. Agreeable.

“A Red，Red Rose”，_____romantic poem，is written by Robert Bums，quite a few of whose
works are involved in _______ nature．
|
A．a，the |
B．the，the |
C．a，／ |
D．the，／ |
Teenagers who do not get enough of the nutrients commonly found in fruits and fish are easier to have bad lungs, coughing and wheezing （喘息）．Teens who eat the least of fruit and especially vitamin C have weaker lungs compared to the others．
Teens who take in less vitamin E, found in vegetable oil and nuts, are more likely to have asthma（哮喘）, Jane Bums at the Harvard School of Public Health found.
Based on these findings．Bums said that current recommended dose（一剂）of vitamin C, 85 mg a day, may not be enough for teens to have healthy lungs．Teens who eat less fruit and don't take in enough fatty acids （脂肪酸） are more likely to have asthma and the signs of breathing difficulty．
Proper amounts of fatty acids are protective, Bums said, though fish, the best source of fatty acids, is particularly unpopular with teenagers．Fatty acids are also found in some nuts as well as some green vegetables'．Smokers who avoid vitamin C will increase their chances of coughing, wheezing and developing phlegm（痰）．
More than 80 percent of teens are getting their recommended doses of vitamin C - mainly from fruit drinks．"I wouldn't approve of drinking them, but at least they're getting their vitamin C from somewhere," Burns said．
Burns added that there are several different ways to get the necessary nutrients．"I think vitamin supplements are fine．I think adding vitamin D to orange juice is fine．But I do think there are added benefits that we don't fully understand of eating whole foods like fruits and vegetables and fish," she said．The researchers did not account for poverty and other factors that often distinguish less-healthy eaters and may explain their findings．
【小题1】According to the passage, what is the problem with teens who don't get enough nutrients?
| A．They are becoming smokers． | B．They don't take enough exercise． |
| C．They eat too much fruit and fish． | D．They are likely to have weaker lungs． |
| A．By drinking juice as much as possible． |
| B．By eating more whole foods． |
| C．By taking vitamin pills． |
| D．By giving up smoking． |
| A．The amount of nutrients teens should take in a day． |
| B．How teens can take in enough nutrients． |
| C．Whether poor teens can prove their findings． |
| D．The fact that teens don't like fish． |
| A．Poor nutrition hurts teens' health． | B．Teens lack proper nutrition． |
| C．Teens are easy to suffer from diseases． | D．More fruit help keep teens healthy． |
