Ques:Eat nuts, live longer.  Researchers have found that those who eat a handful of peanuts every day significantly decrease their risk of dying from all causes compared to those who do not eat nuts. A new study concludes that all types of nuts seem to be protective. Researcher Ying Bao is with the Department of Medicine at Brigham and Women's Hospital and Harvard University Medical School in Boston, Massachusetts. She and her colleagues looked at the impact of nut consumption by analyzing two huge studies that began in 1980 - the Nurses' Health Study, which tracks the of more than 76,000 women, and 42,000 men enrolled in the Health Professionals Follow-up Study. Among the questions asked at the beginning of the studies was, 'how frequently do you eat nuts?'  The information was updated every two to four years. Bao says the participants were followed for three decades. "What we observed is that people who eat more nuts are less likely to die over the next 30 years," said Bao. "So, for example, if a person eat(s) nuts once per day, that person has a 20 percent lower risk of dying." Bao says eating a handful of nuts five or more times per week was associated with a 29 percent reduced risk of dying from heart disease and an 11 percent lower risk of cancer death.  A serving size is 28 grams. Nuts contain nutrients, including high quality proteins, vitamins and minerals, all of which have anti-cancer effects and may help protect the heart. Bao says researchers are planning studies to find out how nuts are beneficial to human health. The study on the health benefits of nuts was funded by the International Tree Nut Council Research and Education Foundation. About Bao's research, which statement is true? A) She has done the research by herself. B) Her research was based on two studies. C) Her research lasted about three years. D) People should eat all kinds of nuts every day.

Ques:Neither television nor radio nor magazines nor books nor any other medium can begin to match newspapers for depth and breadth of coverage  . In fact, all these media themselves depend on newspapers to bring them information that they then process and distribute as their own brand of news. Now many newspapers are locked in a struggle for survival. If they lose--which is by no means impossible--we all lose. The great task for editors and publishers is to respond to the competitive challenge caused by online news, and at the same time use their own online news to increase their profits  . As yet,they haven't figured out a smooth and sure way to do that. So they cut some more to get profit. The cuts in size that they are making are in some cases risky and in others without considering the results. With every cut, publishers tirelessly argue that readers won't even know the difference. The trouble is that by the time customers do notice that they are getting less for their money,it will be too late--too late to notice the reduction in the number of readers. The other big cuts, of course, are in staff  . The victims would be the oldest and most experienced workers because they are the highest paid. While there is plenty of tired _ among them,there is also a lot of talent. When experienced staff leave in large numbers--as they often do now--the newspaper loses great professional memory. But the real loser is the readers, who are suddenly robbed of the insights   that only the experienced reporters can bring. As for the future, there is at least one big, bright sign:intelligent young people will continue to flood into journalism in urgent search of jobs, despite its high demands and modest   pay. According to the passage,which of the following can best describe the author's    attitude towards the ways the editors and publishers have adopted to get profit? A) The author has no objection. B) The author is against them. C) The author has not shown it clearly. D) The author regards them reasonable.

Ques:Global Positioning Systems are now a part of everyday driving in many countries. These satellite-based systems provide turn-by-turn directions to help people get to where they want to go. But, they can also cause a lot of problems, send you to the wrong place or leave you completely lost. Many times, the driver is to blame. Sometimes a GPS error is responsible. Most often, says Barry Brown, it is a combination of the two. We spoke to Mr. Brown by Skype. He told us about an incident involving a friend who had flown to an airport in the eastern United States. There he borrowed a GPS-equipped car to use during his stay. Barry Brown: "And they just plugged in an address and then set off to their destination. And, then it wasn't until they were driving for thirty minutes that they realized they actually put in a destination back on the West Coast where they lived. They actually put their home address in. So again, the GPS is kind of 'garbage in garbage out'." Mister Brown says this is a common human error. But, he says, what makes the problem worse has to do with some of the shortcomings, or failures, of GPS equipment. Barry Brown: "One problem with a lot of the GPS units is they have a very small screen and they just tell you the next turn. Because they just give you the next turn, sometimes that means that it is not really giving you the overview that you would need to know that it's going to the wrong place." Barry Brown formerly served as a professor with the University of California, San Diego. While there, he worked on a project with Eric Laurier from the University of Edinburgh. The two men studied the effects of GPS devices on driving by placing cameras in people's cars. They wrote a paper based on their research. It is called "The Normal, Natural Troubles of Driving with GPS." It lists several areas where GPS systems can cause confusion for drivers. These include maps that are outdated, incorrect or difficult to understand. They also include timing issues related to when GPS commands are given. Barry... What would be the best title for the text? A) driving with GPS can be difficult B) driving confusions can be caused by small screen C) driving without GPS should be much more convenient D) GPS equipment in driving: to be deserted or improved?
