I recall an early 1 with a vice president of a large oil company. “Oh, I just keep a To Do List,“ he said. I pas

16、sed over that quickly, little 2 the importance of what he said. I was in another city the next day and I had lunch with a businessman who 3 owned the town. He was chairman of the gas and light company, president of five 4 companies, and had his hand in a dozen other 5 I asked him how he managed to g

17、et everything done. “Oh, that“s easy,“ he said. “I keep a To Do List,“ The first thing in the morning, he told me, he would list what he wanted to 6 that day. He would arrange the items in priority. During the day he would cross off items and add others as they 7 him. In the evening he would check t

18、o see how many of the items he had 8 still remained undone and then give himself a score. His goal was to cross off every single item. Again and again in the years since, when I have talked to successful people, the To Do List has come up. I have found that one difference between people at the top o

19、f the 9 and people at the bottom is that those at the top use a To Do List every day to 10 their time; those at the bottom don“t. （分数：71.00）填空项 1:_九、Part Reading Compr(总题数：0，分数：0.00)十、Section A(总题数：1，分数：35.50)“Made in China“ lost its novelty (新颖) long ago. The label has become 1 in much of the world

20、, stick to shoes, toys, clothes and a host of other items produced for global companies. What is novelty, however, are China-made goods 2 under Chinese brand names. Only a handful of Chinese firms so 3 have the money and the management technique to establish international 4 . Most of the vast compan

21、ies are struggling to get even national recognition. But the pioneering companies which have started exploring overseas market might be 5 as on the beginning of something big. Some 6 that individually, with the help of enterprising local management or eager multinational partners wanting to add new

22、products to their stable, Chinese brands could become a global phenomenon within a decade, marketed on quality and foreign appeal, as 7 as competitive pricing. The concept of Chinese brands has been evolving through the 1990s, but is now getting 8 attention at home. Although the domestic market is s

23、till robust, a handful of 9 enterprises, or SOEs, including listed Chinese companies, are now looking to establish international brands because they believe the quality of both their products and their management has 10 Chinese joint ventures think their products can compete on quality with foreign

25、s and BrainsA. We all know that exercise is good for you. Staying physically active helps keep your heart healthy and your muscles strong, and in cancer patients it has even been shown to ward off relapse (复发). Now a series of independently conducted studies on the effects of exercise on healthy old

26、er adults, published in the Archives of Internal Medicine, confirms that logging time at the gym not only helps maintain good health but may even prevent the attack of chronic diseases, such as heart disease, osteoarthritis and dementia. B. In one surprising trial, researchers led by Dr. Teresa Liu-

27、Ambrose at the University of British Columbia randomly assigned 155 aging women to three separate groups and directly compared the cognitive effects of two types of exercise: resistance training, done once or twice weekly, in which participants worked out with free weights and weight machines and di

28、d squats and lunges, versus toning and balance exercises, which participants did twice a week. C. By the end of the year long study, the women who weight-trained saw an improvement in their performance on cognitive tests of memory and learning as well as in executive functions such as decision-makin

29、g and conflict resolution women who trained once a week improved their scores in executive functioning by 12.6% while those who did balance and toning exercises showed no such improvement. The muscle-strengthening exercise also helped the volunteers, ages 65 to 75, boost their walking speed, a commo

30、nly used indicator of overall health status in the elderly, as faster pace has been linked with lower mortality. D. The Canadian researchers“ findings were somewhat unexpected, given that previous studies on the issue have typically focused on aerobic exercise, which experts believe enhances cogniti

31、ve function by promoting blood flow to the brain. Liu-Ambrose says her team speculated that anaerobic weight training would have a similar effect for other reasons. First, a resistance-training regimen requires a considerable amount of learning, especially for elderly people who may not be accustome

32、d to the equipment. To learn how to use dumbbells, a leg press or a latissimus pull-down machine correctly, for example, the volunteers were required to focus on the task at hand, master new techniques and retain new information about proper and safe use of equipment. Previous studies have shown tha

33、t such learning can help older adults maintain mental acuity. E. The women also had to remember their weight settings and adjustments to the seats and keep track of the number of repetitions they completed, says Liu-Ambrose. “There is a lot more learning involved that may not occur if you take up a

34、walking program,“ she says, noting that it took the volunteers a good two months to get comfortable with the equipment and the training regimen. In addition, Liu-Ambrose says, other studies have found that people who weight-train show an increase in blood levels of a growth factor that is important

35、for maintaining skeletal mass. This factor, it turns out, also promotes nerve growth, which could be another way that resistance training boosts mental function. F. In a second brain-function study, published in the same journal, scientists in Germany found that increased physical activity was assoc

36、iated with a lower incidence of dementia. In this study, researchers recruited 3,485 elderly residents in Bavaria and asked them about their physical activity. None of the participants had dementia at the start of the analysis, but after two years of follow-up, researchers found that those who exerc

37、ised at least three times a week were half as likely to have developed dementia, compared with the people who reported no physical activity. Based on his results, says lead author Dr. Thorleif Etgen, a professor of psychiatry and psychotherapy at Munchen University, “it doesn“t make a big difference

38、 if you have moderate or high physical activity. The important message is that you do any activity. And even if you start late in life, at 60 or 70, there is a benefit, for it“s never too late to start exercising.“ G. The key words are “moderate or high,“ according to another study that was publishe

39、d in the Archives of Internal Medicine. Dr. Qi Sun, a researcher at Harvard School of Public Health, analyzed 13,000 women participating in the Nurses“ Health Study and found that when it came to exercise, more was better. Compared with women who jogged for 20 minutes a week, those who jogged three

40、hours a week or walked briskly for five hours a week were 760% more likely to age successfully, free of chronic illnesses such as cancer and heart disease, as well as mental and physical impairment. Sun“s group found that this benefit occurred across all weight divisions, meaning that even among tho

41、se who were overweight or obese, women who exercised improved their odds of aging without chronic disease. The effects may apply across different age groups as well; the women were at least 60 years old by the time they enrolled in the study, and while Sun was not able to determine how long they had

42、 been exercising prior to that, the results suggest that the health benefits are not limited to the young. H. That was the same message of the final exercise paper in the journal, by researchers at University of Erlangen-Nuremberg in Germany. In this trial, a group of 246 elderly women were randomly

43、 assigned to an 18-month exercise regimen or wellness program. The women participating in the four-times-weekly exercise sessions, which involved aerobics and balance and muscle training, improved their bone mineral density by nearly 2%. The women in the wellness group, which focused on walking, mus

44、cle relaxation and breathing skills, had a 0.33% increase in bone mineral density over the same time period. I. Despite the positive evidence, however, not all researchers are ready to suggest that exercise is a sure-fire prescription against mental decline or chronic disease in healthy people. To m

45、ake that claim, a large, longer-term, controlled trial would be needed, in which participants are randomly assigned to exercise or not, and are then followed for the development of chronic conditions such as cancer, heart disease or dementia. Still, says Dr. Marco Pahor, director of the Institute on

46、 Aging at the University of Florida and author of a commentary on the studies appearing in the journal, “if you pool all the evidence together, the benefits of exercise seem promising.“（分数：71.00）(1).Experts believe that the aerobic exercises raise people“s cognitive function by stimulating blood blo

47、w to brain.（分数：7.10）(2).Learning of using the resistance-training equipment is good for the elderly people in that it can keep their mind acute.（分数：7.10）(3).According to the studies published in the Archives of Internal Medicine , exercise can keep the healthy elderly from getting some chronic disea

48、ses.（分数：7.10）(4).The result of Liu-Ambrose and his partners“ research about the cognitive effects of two kinds of exercise on aging women shows that resistance training is good for promoting cognitive function.（分数：7.10）(5).In Liu-Ambrose“s research, muscle-strengthening exercises increased the walki

49、ng speed of volunteers aged 65-75.（分数：7.10）(6).In Dr. Marco Pahor“s opinion, according to all evidence provided, it proves that exercise can bring promising benefits.（分数：7.10）(7).According to the research done by University of Edartgen-Nuremberg, different types of exercises taken by elderly women have different effect on their bone mineral density in the same period.（分数：7.10）(8).According to Qi Sun“s research, women who take more exercise have little chance to get some chronic
