Ques:If you don't have a college degree, you're at greater risk of developing memory problems or even Alzheimer's  . Education plays a key role in lifelong memory performance and risk for mental disorder, and it's well documented that those with a college degree possess a cognitive  advantage over those less educated in middle and old age.        Now, a large national study from Brandeis University published in the American Journal of Geriatric Psychiatry shows that those with less schooling can significantly make up for poorer education by frequently engaging in mental exercises such as word games, puzzles, reading, and lectures.        "The lifelong benefits of higher education for memory in later life are quite impressive, but we do not clearly understand how and why these effects last so long," said lead author Margie Lachman, a psychologist. She suggested that higher education may encourage lifelong interest in cognitive efforts, while those with less education may not engage as frequently in mental exercises that help keep the memory agile  .        But education early in adulthood does not appear to be the only route to maintain your memory. The study found that intellectual activities undertaken regularly made a difference. "Among individuals with low education, those who are engaged in reading, writing, attending lectures, doing word games or puzzles once a week or more had memory scores similar to people with more education," said Lachman.        The study, called Midlife in the United States, assessed 3,343 men and women between the ages of 32 and 84 with an average age of 56 years. Almost 40 percent of the participants had at least a 4-year college degree. The researchers evaluated how the participants performed in two cognitive areas, verbal  memory and executive function --- brain processes involved in planning, abstract thinking and cognitive flexibility. Participants were given a series of tests, including tests of verbal fluency, word recall, and backward counting.        As expected, those with... Why are the findings of the Lachman's study promising? A) The lower educated may have the same opportunities to keep up memory. B) We may have ways to cure the people who have memory declines. C) Adopting a different lifestyle can control cognitive functioning. D) We can find out the possibility to have better memories.

Ques:All work and no play makes Jack a dull boy. That saying holds true not only for you and me, but also for some of the most powerful and influential people in the world, such as the presidents of the United States. But how do American presidents spend their vacation time? Let's take a look! Franklin D. Roosevelt, considered one of the greatest presidents in American history, had limited vacation options because of his polio . He began visiting Warm Springs, Georgia in 1924 for its curative waters and later built a 2,000 acre polio treatment center nearby. He liked to cruise the Potomacon his yacht  and three times as president returned to his beloved Canadian island of Campobello, with which he fell in love as a kid. Former President Bill Clinton, however, was never much good at vacationing. His staff had to practically force him to go on vacation his first year in office; his idea of relaxing was reading four good books simultaneously  while enjoying a cigar (chewed, not smoked). He could also lose himself in a game of golf, where his somewhat flexible interpretation of the rules could at times drive his partners crazy. Obama's predecessor  also knows how to relax. Fishing is in the Bush family DNA: for blue sharks off the coast of Maine or anything with fins, almost anywhere else. George W. Bush also relaxed as president by jogging and clearing brush on his Texas ranch. Since leaving office, he has become an active mountain biker and, more recently, has taken up painting. Obama tends to take a winter break in Hawaii, where he was born and raised, and a summer vacation in Martha's Vineyard, off the southern coast of Cape Cod, Massachusetts. In between, he plays basketball every couple of weeks and has been known to do some skeet shooting at Camp David. Obama's favorite pastime, no matter the location, has become easy to spot: golf. What's special when Bill Clinton was playing golf? A) He could often be the top player. B) He could often be the bottom player. C) He did not often respect the rules. D) He usually showed good team spirit.
