A happier heart
Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart.Studies have shown heart benefits from increased blood flow.These benefits are the result of cocoa’s chemicals, which seem to prevent both cell damage and inflammation(炎症).
Better blood pressure
If yours is high, chocolate may help.Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly.
Muscle magic
Chocolate milk may help you recover after a hard workout(锻炼).In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks.
Better for your skin.German researchers gave 24 women a half-cup of special cocoa every day.After three months, the women’s skin was moister(滑润的)and smoother.The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance.
Brain gains
It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain.

Oh, poor digestion can lead to weight problems. Here’s how: When a person feels stressed, the part of the central nervous system that connects digestion switches off. This is called the parasympathetic nervous system(副交感神经系统). At those times of stress, the body can take in food and process some of it, but digestion doesn’t work correctly to digest all the nutritional(营养的)goodness from the food. Poor digestion is not always obvious by observing symptoms; you can get some illnesses but not always. Poor digestion can be seemingly silent.
If you eat when you are stressed, anxious, or nervous, you might as well be eating cardboard for all the nutrients your body gets. Yes, eating when stressed is a gaining situation. Now you might think, well, if I’m not digesting, the calories aren’t getting handles, so I should be losing weight. Good idea, but wrong reality. When digestion is not proper, the body starts “starving” from lack of necessary nutrients(营养物). Yes, it goes into a starvation(饥饿)problem and starts absorbing(吸收) fat and energy. It thinks it’s in a famine(饥荒). The good news is that it’s easy to make some corrections and get rid of stress at mealtimes.
If you feel stressed often, it can be helpful to take other food that contains multiple B vitamins. These help, but you could still find yourself stressed at mealtimes.

A.how to deal with stress at mealtimes |
B.what kind of food can be easily digested |

C.Eating too much can cause anxiety. |
D.The stress problem can be solved during eating. |
A.Poor digestion cannot absorb much nutritional goodness from the food. |
B.People with poor digestion take in food and process all of it. |

D.Poor digestion will not lead to overweight problems. |
A.The body does not take in what they eat. |
B.The digestion system becomes incorrect. |
C.People cannot eat much when unhappy. |
D.The body will begin to absorb too much fat. |
I have to cook for my family and prepare what they want to eat. I’m trying to plan out this better so I have some of these unusual foods ready for myself.
I’ve read several books written by Ann Wigmore and like her approach to the living foods.
Last week I attempted fasting(禁食)and failed. I lasted five days by having carrots, spinach, apples and other vegetarian diets I could get my hands on. I was doing fine until I drank some coffee. I kind of proved it in my mind to have the coffee but it only made me excited and then I couldn’t sleep well and felt hungry and weak. So I stopped and went back to the old way of eating with the family.
This week I started to make a drink called rejuvelac made of sprouted wheat(芽麦). This is fairly new to do for me and the drink smelled sort of musty(发霉的)and tasted kind of like a musty lemon. The kids tasted it and almost threw up but surprisingly it tasted good to me. It is supposed to help in digestion(消化).
I’ve made some attempts to grow wheat grass. I think I have figured that out as long as I keep it away from birds and our horses. I have two habits to get rid of, drinking coffee and smoking. I quit smoking last month but something happened, so I started up again. I’m very frustrated(受挫的) with the smoking and really have a desire to quit for good. Anyhow I will keep this updated on my progress.

Ray’s parents remembered that at age four, Ray surprised them by fixing a broken vacuum cleaner(吸尘器). When he was ten, he speedily constructed the family color television from a kit. Later, he succeeded in assembling(组装) a complex stereo system after two experts had failed to do the job.
When Ray was ten, he convinced his parents to buy him a computer. In a short time, Ray was able to do amazing things with the computer. Ray shared his enthusiasm for computers with Dr. Tisman, who used a computer for his research. The two discussed computers and medicine frequently. Amazingly, Ray understood the biology and chemistry related to Dr. Tisman’s medical research without any previous instruction.
Ray then worked with Dr. Tisman after school. He helped conduct research with the equipment and kept it in working order. The purpose of the research was to test the effectiveness of mixing an old cancer drug with certain vitamins. Ray analyzed patient test results by computer, while Dr. Tisman handled all patient contact. Together, they came up with solid research that helped advance cancer treatment.
In 1988, 14 - year - old Ray went with Dr. Tisman to a meeting of the American Federation for Clinical Research(AFCR), where Ray presented their initial research findings. Using terminology(术语) beyond the grasp of most kids his age, Ray told the scientists how the new drug mixture caused fewer and milder side effects for cancer patients.
A year later, Ray returned to the meeting to update the findings of his and Dr. Tisman’s research. By then, he had become well - known for his devotion to finding cures for sick patients. Stories about him appeared in hundred of newspapers around the world. He appeared on television newscasts and talk shows.
Ray continued to spend most free hours working with Dr. Tisman. The two began studying the effects of vitamins on babies inside the womb(子宫). However, Ray’s main interest remained cancer treatment, and he continues his research today.
小题1:According to the passage, Ray______.
A.is a boy of many gifts |
B.is very helpful to his parents |
C.learned fast under Dr. Tisman’s instruction |
D.stopped working with Dr. Tisman after his success |
A.He succeeded in finding cures for cancer. |
B.He made a new discovery in cancer treatment. |
C.He convinced Ray to become a partner of him. |
D.He taught Ray knowledge related to his research. |
A.His presentation at AFCR. | B.His great skills in computer. |
C.His devotion to cancer research. | D.His appearance on television newscasts. |
A.providing different cancer treatments |
B.proving the effects of vitamins on babies |
C.finding the side effects of a cancer drug |
D.testing the effectiveness of a new drug mixture |
A study finds that, contrary to many parents" fears, owning cats or dogs does not increase a child"s risk of developing allergies, and in fact, may actually protect them. The study"s lead author, Dr. Dennic Ownby of the Medical College of Georgia, says that even he was "very surprised" by the results. Ownby and colleagues followed more than 470 children from birth to age 6 or 7, comparing those exposed to cats and dogs during their first year of life to those who were not.
By using skin-prick tests for detecting common allergies, the researchers found that, contrary to what many doctors had been taught for years, children who had lived with a pet were not at greater risk.
Even more remarkable, children who had two or more dogs or cats had an even greater reduction, up to 77 percent, in risk of allergies. Researchers suggest this protective effect may be the result of early exposure to lots of bacteria that are carried by dogs and cats. Exposing young children to these bacteria helps" exercise" their immune systems early in life so that they"re better able to resist allergic diseases later.
There"s something very important in that first year of life when the immune system is developing that we can retrain it away from an allergic response, said Dr. William Davis.
And while researchers are not encouraging parents to buy dogs or cats just to reduce a child"s allergy risk, they say if a family already has one or more animals, there"s no need to get rid of them.
小题1:Why do the researchers feel “very surprised” by the results of the study?
A.Because the results are contrary to their expectation. |
B.Because so many children are playing with cats and dogs. |
C.Because parents are so much worried about their children. |
D.Because children with animals may develop allergies easily. |
A.will lose the chance to develop immune system |
B.may suffer allergic diseases more often |
C.will reduce the harm from bacteria |
D.can keep doctors away |
A.pets are ill-treated by their owners |
B.less families would like to own cats and dogs |
C.keeping pets is a good way to keep children healthy |
D.the results of the study can make families with pets feel at ease |
A.the early life |
B.an allergic disease |
C.immune system |
D.something important |
A.How to protect your kids from allergies |
B.Your pets may be helping your kids |
C.Bacteria do good to your kids |
D.Advantages of owning pets |
