Article: People who drink moderately , exercise, quit smoking and eat five servings of fruit and vegetables each day live on average 14 years longer than people who adopt none of these behaviors, researchers said on Tuesday. Much evidence has shown these things contribute to healthier and longer lives, but the new study actually quantified their combined effect, the British team said. "These results may provide further support for the idea that even small differences in lifestyle may make a big difference to health in the population," the researchers wrote in the journal PLoS Medicine. Between 1993 and 1997 the researchers questioned 20,000 healthy British men and women about their lifestyles. They also tested every participant's blood to measure vitamin C intake, which shows how much fruit and vegetables people ate. Then they assigned the participants aged 45-79 a score of between 0 and 4, giving one point for each of the healthy behaviours. After allowing for age and other factors that could affect the possibility of dying, the researchers determined people with a score of 0 were four times as likely to have died. Also a person with a health score of 0 had the same risk of dying as someone with a health score of 4 who was 14 years older. The lifestyle change with the biggest benefit was giving up smoking, which led to an 80 percent improvement in health, followed by eating fruits and vegetables. Moderate drinking and keeping active brought the same benefits. With this information, public-health officials should now be better encouraging behavior changes likely to improve the health of middle-aged and older people.

A computer algorithm works almost as well as a trained linguist in reconstructing how dead " _ " would have sounded, says a new study. "Our computer system is doing a basic job right now," says Alex Bouchard-Cote, an assistant professor in the department of statistics at the University of British Columbia and lead author of the paper describing the algorithm. But the program does a good enough job that it may be able to give linguists a head start, the statistician added. For centuries, scholars have reconstructed languages by hand: looking at the same word in two or more languages and making educated guesses about what that word's "ancestor" may have sounded like. For example, the Spanish word for man ("hombre") and the French word for man ("homme") developed from the Latin word "homo." The way linguists compare words from descendant languages to reconstruct the parent language is called, appropriately, the comparative method. The early 19th-century linguist Franz Bopp was the first to compare Greek, Latin and Sanskrit using this method. Jacob Grimm, one of the Brothers Grimm of fairy tale fame, used the comparative method to show how Germanic languages developed from a common ancestor. The difference between that and Bouchard-Cote's program, the statistician says, "is we do it on a larger scale." As a proof of concept, Bouchard-Cote fed words from 637 Austronesian languages (spoken in Indonesia, the Philippines, Malaysia and more) into the new algorithm, and the system came up with a list of what the ancestor words of all those languages would have sounded like. In more than 85 percent of cases, the automated reconstruction came within one character of the ancestor word commonly accepted as true by linguists. The algorithm won't replace trained human linguists, but could speed up language analysis. Using a computer to do large-scale reconstruction offers another advantage. Bouchard-Cote says, "With big data sets, you can really start finding... Question: According to Bouchard-Cote, reconstructing the dead "protolanguages" might _ . Options: A: arouse people's interest in when Europe was settled B: allow us to find answers to some historical questions C: enable us to picture the way linguists communicated D: help figure out how the wheel was invented

Q: Read the article and select the best answer. Article: Single people, especially women, are stigmatized in our society: We're all familiar with the image of a sad, lonely woman eating ice cream with her cats in her pajamas on Saturday night. But about 45 percent of US adults aren't married and around one in seven lives alone. This might be you. Research shows that young people's expectations about their marital status (e.g. the desire to be married by 30 and have kids by 32) have little or no relationship to what actually happens to people. So, go with the flow. And, if you're single, you're in good company. Single people spend more time with friends, volunteer more, and are more involved in their communities than married people. Never-married and divorced women are happier, on average, than married women. So, don't buy into the myth of the miserable singleton. If you do get married, keep going with the flow. Relationship satisfaction, financial security, and happy kids are more strongly related to flexibility in the face of life's challenges than any particular way of organizing families. The most functional families are ones that can bend. So partnering with someone who thinks that one partner should support their families and the other should take responsibility for the house and children is a recipe for disaster. So is being equally rigid about non-traditional divisions of labor. It's okay to have ideas about how to organize your family but your best bet for happiness is to be flexible. Buying a home is often taken for granted as a stage on the path to adulthood. But the ideal of universal home ownership was born in the 1950s. It's a rather new idea.With such a short history, it's funny that people often insist that buying a house is a fool-proof investment and the best way to secure retirement. In fact, buying a house may not be the best choice for you. The mortgage may be less than rent, but there are also taxes, insurance, and the increasingly common Home Owners Association (HOA) fees. You may someday sell the house for more than you bought it but, if... Question: According to the passage, what can be a happy family?

C: The happy family believes the traditional divisions of labor. D: The happy family has relationship satisfaction, financial security and happy kids.
