Article: To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount.That is according to a study published this Monday in the Public Library of Science Medicine Journal. After tracking more than 20,000 people aged 45 to 79 years in the United Kingdom from about 1993 to 2007, Kay-Tee Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived all average of 14 years longer than those who didn't. "We've known for a long time that these behaviors are good things to do, but we've not seen this benefit before, "said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council."The benefit was also seen regardless of whether or not people were fat and what social class they came from." Study participants scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake. Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes.But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years. "We can't say that any person could gain 14 years by doing these things, "said Dr.Tim Armstrong, a physical activity expert at the World Health Organization."The 14 years is an average across the population of what's theoretically possible." "Most people know that things like a good diet matter and that smoking isn't good for them, "Susan Jebb said."We need to work on providing people with much more practical support to help them change."

Healthy Habits May Give Extra 14 Years

Read the following article and select the best answer. Article: Raised in a motherless home, my father was extremely tightfisted towards us children. His attitude didn't soften as I grew into adulthood and went to college. I had to ride the bus whenever I came home. Though the bus stopped about two miles from home, Dad never met me, even in severe weather. If I _ he'd say in his loudest father-voice, "That's what your legs are for!" The walk didn't bother me as much as the fear of walking alone along the highway and country roads. I also felt less than valued that my father didn't seem concerned about my safety. But that feeling was cancelled one spring evening. It had been a particularly difficult week at college after long hours in labs. I longed for home. When the bus reached the stop, I stepped off and dragged my suitcase to begin the long journey home. A row of hedge edged the driveway that climbed the hill to our house. Once I had turned off the highway to start the last lap of my journey, I always had a sense of relief to see the hedge because it meant that I was almost home. On that particular evening, the hedge had just come into view when I saw something gray moving along the top of the hedge, moving toward the house. Upon closer observation, I realized it was the top of my father's head. Then I knew, each time I'd come home, he had stood behind the hedge, watching, until he knew I had arrived safely. I swallowed hard against the tears. He did care, after all. On later visits, that spot of gray became my watchtower. I could hardly wait until I was close enough to watch for its secret movement above the greenery. Upon reaching home, I would find my father sitting innocently in his chair. "So! My son, it's you!" he'd say, his face lengthening into pretended surprise. I replied, "Yes, Dad, it's me. I'm home." Question: What made the author feel upset was _ . - the tiredness after long hours in labs. - the fear of seeing something moving. - the feeling of being less than valued. - the loneliness of riding the bus home.
the feeling of being less than valued.

Q: Read the following article and select the best answer. Article: Sensing phantom phone vibrations is a strangely common experience. Around 80% of us have imagined a phone vibrating in our pockets when it's actually completely still. Almost 30% of us have also heard non-existent ringing. Are these signs of madness caused by digital culture? Not at all. In fact, phantom vibrations and ringing indicate a fundamental principle in psychology. Psychologists use a concept called Signal Detection Theory to guide their thinking about the problem of perceptual judgments. Working through the example of phone vibrations, we can see how this theory explains why they are a common and unavoidable part of healthy mental function. When your phone is in your pocket, the world is in one of two possible states: the phone is either ringing or not. You also have two possible states of mind: the judgment that the phone is ringing, or the judgment that it isn't. Obviously you'd like to match these states in the correct way. True vibrations should go with "it's ringing", and no vibrations should go with "it's not ringing". Signal detection theory calls these faithful matches a "hit" and a "correct rejection" But there are two other possible combinations: you could mismatch true vibrations with "it's not ringing" (a "miss"); or mismatch the absence of vibrations with "it's ringing" (a "false alarm"). This second kind of mismatch is what's going on when you imagine a phantom phone vibration. What does that mean in terms of your phone? We can assume that people like to notice when their phone is ringing, and that most people hate missing a call. This means their perceptual systems have adjusted their bias to a level that makes misses unlikely. The unavoidable cost is a raised likelihood of false alarms of phantom phone vibrations. The trade-off between false alarms and misses also explains why we all have to put up with fire alarms going off when there isn't a fire. It isn't that the alarms are badly designed, but rather that they are very sensible to smoke and heat and biased to avoid missing a...
