Dieters' who eat meals high in protein might lose a bit more weight than those who get less protein and more carbohydrates all other things being equal, a new analysis of past studies suggests. Researchers found that over an average of 12 weeks, people having a highprotein 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." What is Levine's attitude towards the conclusion of the studies? A) Doubtful. B) Supportive. C) Curious. D) Agreeable.

What exactly is a lie ?Is it anything we say which we know is untrue ?Or is it something more than that ?For example, suppose a friend wants to borrow some money from you. You say "I wish I could help you, but I am short of money myself." In fact , you are not short of money but your friend is in the habit of not paying his debts and you don't want to hurt his feelings by reminding him of this. Is this really a lie ? Professor Jerald Jellison of the University of southern California has made a scientific study of lying. According to him, women are better liars than men, particularly when telling a "white lie", such as when a woman at a party tells another woman that she likes her dress when she really thinks it's terrible. However, this is only one side of the story. Other researchers say that men are more likely to tell more serious lies, such as making a promise that they have no intention of carrying out. This is the kind of lie politicians and businessmen are supposed to be particularly skilled at :the lie from which the liar hopes to profit or gain in some way. Research has been done into the way people's behavior changes in a number of small, unimportant ways when they lie. It has been found that if they are sitting down at the time, they tend to move about in their chairs more than usual. To the trained observer they are saying "I wish I were somewhere else now". They also tend to touch certain parts of the face, particularly the nose. One explanation of this may be that lying causes a slight increase in blood pressure. The tip of the nose is very sensitive to changes and the increased pressure makes it itch. Another gesture that gives liars away is what the writer Decmond Morris in his bookMan Watching calls the "mouth cover". He says that there are several typical forms of this ,such as covering part of the mouth with the fingers, touching the upper lip or putting a finger of the hand at one side off the mouth. Such a gesture can be understood as an unconscious attempt on the part of the liar to... Research suggests that women _ . A) are better at telling less serious lies than men B) generally lie for more than men do C) often make promises they intend to break D) lie at parties more often than men do

Ques: Singles' Day ---- the Chinese opposite of Valentine's Day has turned into a massive online shopping event. It is a day when single people are supposed to buy themselves presents. But there are sociological reasons behind China's "celebration" of single life. And the imbalance could have big consequences for the country. There were 34 million more men than women in China in 2011. Part of that is natural - usually there are 105 boys born for every 100 girls. But the Chinese gender ratio at birth is much more obvious. It was 116 boys to 100 girls in 2012. The one child policy is largely to blame. Brought in to limit population expansion, the policy allows only one child per family. But because male children are seen as more valuable, as well as more likely to support their parents in old age, some parents choose to have a son over a daughter. The result is that large numbers of men will likely never get married. In fact, one study has predicted that by 2030, 1 in 5 Chinese men in their 30s will never have married, while another states that 94% of unmarried people in China are men. Traditionally, China has seen high levels of marriage, usually among the young. Besides, the increased education and career opportunities for women have meant that marriages are happening later. It is also traditional that women often marry men of a higher socioeconomic status than themselves. So women at the top and men at the bottom find themselves alone. One study has even suggested a link between an imbalanced gender ratio and growth in violent crime in the country. Singles' Day can't solve all the problems China's singles face. Indeed, it is possible that it is causing even more problems, as men resort to increasingly risky lines of work to increase their chances of gaining money and thus a wife. I am worried that as money starts to overcome romance, there is evidence that China's marriage market is increasingly materialistic. What made women in China get married late? A) Their support of the government's late marriage policy. B) Their higher education level and more work chances. C) That they expect to enjoy their single time when young. D) That there are too many excellent young men to choose from.
