In the Aerobics Center Longitudinal Study, more than 32,000 people (25,000 men and 7,000 women) were given a preventive medical examination that included a machine exercise test to measure physical fitness. They were given a physical fitness score, with one being the lowest and five being the highest fitness level. Then these people were followed for an average of 8 years. During this time, 179 men and 44 women died of cancer.
Data from the Aerobics Center Longitudinal Study show people have lower rates of cancer with higher levels of physical fitness. Studies from the Cooper Institute for Aerobics Research in Dallas suggest that men with high fitness levels are less likely to die of cancer.
The Aerobics Center Longitudinal Study also found that fitness level was more important than weight in predicting longevity (长寿). While results showed that fitness and normal weight are the ideal combination, researchers found that men who were fat but performed well in the machine performance had just a slightly increased all-cause death rate, including cancer, compared to the more slim men. The fat, but fit, men particularly lived longer than the slim, but flabby (肌肉松弛的), men.
These statistics called for a warning to the overweight: The first health goal for the overweight should be to become as fit as possible at their current weight.

小题3:C
小题4:A
解析
试题分析：本文叙述的是一项健康调查报告，讲述的是体育锻炼对癌症的影响以及锻炼和身体健康之间的关系。
小题1:A 主旨大意题。根据文章主题段第一段Lack of exercise is considered a risk factor for cancer. There is considerable evidence that inactivity is connected with increased risk for lung cancer, breast cancer, etc.可知本文讲述的是锻炼对减少患癌症的可能性有很大的影响。故A正确。
小题2:B 段落大意题。在文章第二段中In the Aerobics Center Longitudinal Study, more than 32,000 people (25,000 men and 7,000 women) were given a preventive medical examination that included a machine exercise test to measure physical fitness. They were given a physical fitness score, with one being the lowest and five being the highest fitness level.可知这个研究正是关于锻炼和癌症之间的联系，故B正确。
小题3:C 推理题。根据文章倒数第3行The fat, but fit, men particularly lived longer than the slim, but flabby (肌肉松弛的), men.可知C项说法是错误的，最重要的不是保持身材苗条，而是身体健康。
小题4:A 细节题。根据文章最后2行These statistics called for a warning to the overweight: The first health goal for the overweight should be to become as fit as possible at their current weight.可知最主要的是提高健康的水平，故A正确。
点评：本文叙述的是一项健康调查报告，讲述的是体育锻炼对癌症的影响以及锻炼和身体健康之间的关系。

试题【Lack of exercise is considered a risk factor for cancer. There is considerable e】；主要考察你对题材分类等知识点的理解。[详细]
举一反三
I know lots of women who don’t have breakfast, and they have many different excuses for doing it. Some say they don’t have time, others think they’re “saving” calories（卡路里）, still others just don’t like breakfast food.
But eating in the morning is very important when you’re trying to lose weight. Eating just about anything from 300 to 400 calories would be better than nothing at all.
Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers found that those who don’t have breakfast have a bigger chance of gaining weight than those who regularly have a morning meal.
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,”I put away the leftovers instead of eating more that night. Try it…you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.
小题1:The word “leftovers” in Paragraph 1 probably means __________.
| A．pizza topped with fruit | B．things left undone |
| C．food remaining after a meal | D．meals made of vegetables |
| A．be careful about what you eat | B．eat something for breakfast |
| C．heat up food before eating it | D．eat calorie-controlled food |
| A．Many people have wrong ideas about breakfast. |
| B．Working women usually have breakfast in a hurry. |
| C．There are some easy ways of cooking a meal. |
| D．Eating vegetables helps save energy. |
| A．who go to work early | B．who go to bed late |
| C．who eat before sleep | D．who want to lose weight |
| A．Better eat up all the food at dinner in the night. |
| B．Better eat less in the night. |
| C．Better eat leftovers in the morning. |
| D．Better get up late and eat nothing in the morning in order to burn more calories. |
Most sports have some kind of running or jumping So experts at many shoe companies work hard to design good sport shoes. First, a designer enters a plan for a shoe into a computer .Engineers then improve the design. A second computer designs a model for the shoe. Then a few pairs are made. Next, the shoe is tested.
Different kinds of sports shoes are made for different uses. Some are made to help marathon(马拉松) runners save energy during a race. Some are made for the stop-and-go kind of running tennis players. But all sport shoes have one thing in common: they are designed to help people’s feet comfortable during sports. Today, nearly every sport has its own special shoe designed for just the kind of running that sport needs.
小题1:The first in making a new shoe is to ________.
| A．make a computer | B．put a design plan into a computer |
| C．design a shoe model | D．test several pairs |
| A．Because they are comfortable to wear. |
| B．Because they help to develop leg muscles. |
| C．Because they help to change body weight. |
| D．Because they are both good and cheap. |
| A．The number of the bones of human muscles. |
| B．The design for a shoe model. |
| C．The materials of sport shoes. |
| D．The effect of shoes upon sports. |
| A．Three | B．Four | C．Five | D．Six |
| A．are made in different shoe companies |
| B．are designed for people of the different weight |
| C．are of the same price |
| D．meet the needs of different sportsmen |
For the study, researchers at the Albert Einstein College of Medicine in New York selected 34adults, men and women. All of the volunteers had played soccer since childhood and now competed year-round in adult soccer leagues. Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year, as well as whether they had experienced any known concussions (脑震荡) in the past.
Then the players completed computerized tests of their memory and other learning skills and had their brains scanned, using a complicated new M.R.I. technique which can find structural changes in the brain that can"t be seen during most scans.
According to the data they presented at a Radiological Society of North America meeting last month, the researchers found that the players who had headed the ball more than about 1,100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory, attention and the processing of visual information, compared with players who had headed the ball fewer times.
This pattern of white matter loss is "similar to those seen in traumatic (外伤的) brain injury", like that after a serious concussion, the researchers reported, even though only one of these players was reported to have ever experienced a concussion.
The players who had headed the ball about 1,100 times or more in the past year were also generally worse at recalling lists of words read to them, forgetting or fumbling the words far more often than players who had headed the ball less.
小题1:The passage is most probably a______.
| A．news report | B．research report |
| C．story for soccer players | D．text for doctors |
| A．Computerized test. | B．Questionnaire.. |
| C．Scanning. | D．M.R.I. technique. |
| A．significant effect on brain | B．little effect on one"s brain |
| C．nothing to do with the brain injury | D．one"s memory improved |
| A．Playing soccer frequently. | B．Tests of their memory. |
| C．White matter loss. | D．Information processing. |
| A．remembering | B．misunderstanding |
| C．recalling | D．missing |
Of course, one way to avoid these medical mysteries is to keep dangerous organisms out of the food supply. This is easier said than done, but scientists keep looking for new ways.
Scientists in the United States have developed an experimental system that uses a high-tech optical scanner. The system is designed to identify the presence of contaminants(致污物) like soil or animal waste on fresh produce. These can be sources of E. coli. E. coli bacteria naturally live in the intestines(肠) of humans and many animals. Most kinds of E. coli are harmless but some can make people sick.
The new scanner can also show damage and imperfections that might make the produce unappealing to shoppers.
Scientists designed the system at a Department of Agriculture research center in Beltsville, Maryland. Moon Kim of the Agricultural Research Service led the team.
MOON KIM: “We were requested, we were asked, to develop a method to detect contamination in produce. So we started with the apple as the model sample.”
The scanner uses a high-speed camera placed over the conveyer belt that moves the produce along. As the apples move along the belt, the scanner captures images of each piece of fruit.
Moon Kim says the team hopes the system will be available before long.
MOON KIM: “We are targeting for development in commercial plants for the next several years.”
The scanner can direct a sorting machine to separate the bad apples from the good ones. The system is currently able to show the surface of only half the apple as it speeds by. The inventers hope to improve the process so it can show the whole surface.
小题1:What is the main topic of the text?
| A．Bacteria. | B．A high-tech scanner. | C．A camera | D．Food safety. |
| A．broke out all over the world | B．comes from soil or animal waste |
| C．is extremely harmful to health | D．does not cause illness |
| A．can help to sort out different fruits |
| B．make the produce appeal to shoppers |
| C．can only capture images of the whole apple |
| D．can identify the presence of contaminants |
| A．The scanner needs to be improved. |
| B．The scanner will be available in the next several years. |
| C．Moon Kim is unwilling to develop the scanner. |
| D．The scanner is connected to a sorting machine. |
Although considered an excellent form of exercise，jumping rope has never gained widespread acceptance because of two fundamental reasons．First，most people recognize jumping rope as an excellent form of cardiovascular (心血管的) exercise，but they also believe that it is simply too difficult．In other words，they don"t think they"ll be able to continue jumping for the near 20 minutes that it takes to achieve a beneficial physical result．Second, many view it as somewhat boring and too repetitive-not as something fun or enjoyable．
As a matter of fact，jumping rope can be great fun if you find a proper way to practise it．Instead of doing the usual two-foot bounce over and over again，people good at rope-jumping often change their pattern every 10 or 20 jumps．A single bounce，a double bounce，a skip，a knee-up，side swings，as well as a variety of other easy-to-learn free-style rope-jumping．
Now researchers are learning that jumping rope also prepares the brain for learning．It is an exercise allowing both brain hemispheres(半球)to perform in parallel(并行地)to each other．In short，jumping rope can be a life-long activity requiring little equipment，time and space，yet leading to a much healthier life．
小题1:From the first paragraph we learn that_______ ．
| A．all people now have more advanced equipment |
| B．jumping rope has disappeared from people"s memories |
| C．racing around the playground was preferred |
| D．people now like to have exercise in a gym |
| A．it benefits the cardiovascular system |
| B．it requires little equipment，time and space |
| C．it is neither easy nor enjoyable |
| D．it is considered boring |
| A．there are many ways to follow |
| B．the usual way should not be used |
| C．the easiest way is always the best |
| D．there is only one proper way to follow |
| A．only prepares the brain for learning. |
| B．is suitable for students only |
| C．helps both brain hemispheres work together |
| D．can be dangerous for old people |
| A．He is arguing against it. | B．He is sitting on the fence of it. |
| C．He is in favor of it. | D．He is not clear about it. |
