Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.

The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.

“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK. w.w.w.k.s.5.u.c.o.m

“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”

What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.

“This gender difference might just explain why women live longer than men,” said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. “The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.

The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

If you don’t have a college degree, you’re at greater risk of developing memory problems or even Alzheimer’s (老年痴呆). 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（认知的） 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 (敏捷地).

       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 (言语的)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 higher education said they engaged in cognitive activities more often and also did better on the memory tests, but some with lower education also did well, explained Lachman.

       “The findings are promising because they suggest there may be ways to level the playing field for those with lower educational achievement, and protect those at greatest risk for memory declines,” said Lachman. “Although we can not rule out the possibility that those who have better memories are the ones who take on more activities, the evidence is consistent with cognitive plasticity (可塑性), and suggests some degree of personal control over cognitive functioning in adulthood by adopting an intellectually active lifestyle.”

What is the text mainly about?

       A. Higher education has a better cognitive advantage.

       B. Better memories result from college degree.

       C. Cognitive activity does good to one’s mind.

       D. Poor education has more risk of memory declines.

According to the result of Margie Lachman’s study, we can conclude that ________.

 A. education is responsible for the lifelong memory performance and risk for mental disorder

 B. education early in adulthood can be the only route to maintain your memory

 C. those with higher education did better on the memory tests than those with lower education

 D. an intellectually active lifestyle does help to maintain your memory

What do we know about the study called Midlife?

     A. Participants each were given a battery to test their memory.

     B. The average age of the participants are 56 years old.

     C. Participants had to perform in one of the two cognitive areas.

     D. One in four of the participants had a 4-year college degree.

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.

The Super Bowl is the annual championship game of the National Football League (NFL), the highest level of professional American football in the United States, becoming a season that begins in the late summer of the previous calendar year. The Super Bowl uses Roman numerals to identify each game, rather than the year in which it is held, with Super Bowl I being the 1966 season championship game, when the Green Bay Packers beat the Kansas City Chiefs. Super Bowl XLVI (46) was played at Lucas Oil Stadium in Indianapolis, on February 5, 2012, to determine the champion of the 2011 season; the New York Giants beat the New England Patriots.

The game was created as part of a merger agreement between the NFL and its rival league, the American Football League (AFL). It was agreed that the two leagues’ champion teams would play in an AFL--NFL World Championship Game until the merger was to officially begin in 1970. After the merger, each league was appointed as a “conference”, and the game was then played between the conference champions. Currently, the National Football Conference (NFC) leads the series with 25 wins to 21 wins for the American Football Conference (AFC).

The day on which the Super Bowl is played, now considered to be an existing American national holiday, is called “Super Bowl Sunday”, though it is not determined by the government. It is the second—largest day for U.S. food consumption, after Thanksgiving Day. In addition, the Super Bowl has frequently been the most watched American television broadcast of the year.

Because of its high viewership, commercial airtime during the Super Bowl broadcast is the most expensive of the year. Due to the high cost of investing in advertising on the Super Bowl, companies regularly develop their most expensive advertisements for this broadcast. As a result, watching and discussing the broadcast’s commercials has become a significant aspect of the event. In addition, many popular singers and musicians have performed during the event’s pre-game and halftime ceremonies because of the exposure’s attracting more fans.

1.What does the Super Bowl use to show each game?

A．The year when the game is held.

B．English letters.

C．Roman numerals

D．Arabic numerals

2. What does the underlined word “merger” in the second paragraph refer to?

A．Union.                                B．Appearance.

C．Division.                              D．Competition.

3.According to the third paragraph, we can know that_______.

A．the Super Bowl Sunday is an official national holiday

B．the Super Bowl Sunday is the biggest day for U.S. food consumption

C．the Super Bowl has owned the biggest TV audience among all games

D．Thanksgiving Day is the second--largest day for U.S. food consumption

4.We can infer from the last paragraph that________.

A．singers and musicians perform during the event’s ceremonies to get more attention

B．people seldom discuss the broadcast’s commercials

C．commercial companies make much money by broadcasting advertisements

D．commercial companies are not interested in the Super Bowl
