Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes(酶)that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic (酸性的). To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat . Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism(新陈代谢) becomes inactive, and then result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious(恶性的) circle in its tracks, people need to consume food and supplements that will neutralize （使…中和）the acid already accumulated in body. Eating the right types of raw and whole foods can help. it’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production.

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.
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.

Just when scientists think they have discovered and recorded every species of insect that crawls the earth they find something new. Earlier this month, Peter Jager, the head of Frankfurt’s Senckenberg Research Institute reported the discovery of a unique eyeless spider.
The creature that has a leg span (跨度) of six centimeters and a body size of just twelve millimeters was found in a cave inside the tiny nation of Laos, in Southeast Asia. It was identified as a member of the Huntsman spider, a large family that consists of 1100 species. However, the other members of the family all have eyes. The spider is the first one that has no eyes. They believe that the kind of spider has adapted to the fact that they do not really need the eyes to such a degree that they have dispensed with them altogether.
But they are not the only creature to have done that. Over the years, scientists have discovered completely blind cave fish, and even a freshwater crab, which happens to live in the same cave as this eyeless spider!
Surrounded by Burma and China on the northwest, Vietnam on the east, Cambodia on the south and Thailand on the west, the landlocked nation of Laos is filled with a large number of new and exotic (新奇的) species. In the last few years researchers have discovered the Saola—never-before-seen antelope-like creature, a small deer species called muntjacs, a tiny stripped rabbit and a rock rat that was thought to have been extinct 11 millions years ago. In addition to that it is also home to over one hundred species of large mammals ranging from tigers to macaques and over 165 species of amphibians (两栖动物) and reptiles like the terrible King cobra and the noisy Tokay gecko, a permanent resident inside most Laos households.

Worried about how many calories you will get in that piece of pizza, chocolate cake or bag of chips? A new iphone application Mealsnap may help. Users just need to take a picture of the meal with the phone, and it will give a calorie read-out almost immediately.
Mealsnap was developed by DailyBurn, a health social network that focuses on helping its users lead healthier lifestyles. It has created several other health and diet-related iphone applications. The applications gives users a quick reply. To do that, it matches the taken picture to a databank containing the calorie information of nearly 500,000 kinds of food. Users then get the range of calories for the meal that is photographed.
We started with something simple — an apple. A couple of minutes later the application replied that it was an apple and between 64 and 96 calories. More impressive was the reply we received after sending a photo of mixed salad bowl. Mealsnap replied that the bowl contained “yellow rice with corn, boiled eggs and beans” and that the food was between 532 and 798 calories.
Mr. Smith, director of DailyBurn, said that usual calorie counting needed a long time, but that the application made it easier to know the calories in food. That’s why it is so popular among those who are trying hard to lose weight.
In addition, Mealsnap can serve as a food diary. No need to write down what they’ve eaten, the photos will be stored. Then users can keep a visual log (记录). Mr. Smith said: “It’s like a food journal, but easier. All you do is to take the picture. The simple act of recording something can cause a psychological change that can help people on their health journey. Knowing the calorie range makes me think more about what I’m eating.
60. The purpose of DailyBurn is to _______.
| A．help people have a healthy life |
| B．make iphone more popular |
| C．help people find ways to lose weight |
| D．persuade people to buy iphone products |
61. We can know from the passage that Mealsnap is ________.
| A．a camera | B．a phone | C．a calculator | D．an application |
62. What can be learned from the third paragraph?
| A．Mealsnap can also tell what the food is. |
| B．Mealsnap is only useful for simple things. |
| C．The result of Mealsnap isn’t always right. |
| D．Mealsnap needs a long time to show the calorie range. |
63. Which would be the best title for the passage?
| A．Mealsnap iphones work as a health signal |
