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. 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 the 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 circle in its tracks, people need to consume food and supplements that will neutralize 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. If you truly want to change and help your body heal itself, you need to take an active approach.

People diet to look more attractive．Fish diet to avoid being beaten up，thrown out of their social group，and getting eaten as a result．That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists．

　　The research team have discovered that subordinate(低一等的) fish voluntarily diet to avoid challenging their larger competitors．"In studying gobies we noticed that only the largest two individuals，a male and female，had breeding（繁殖）rights within the group，" explains Marian Wong．"All other group members are nonbreeding females，each being 5-10% smaller than its next largest competitor．We wanted to find out how they maintain this precise size separation．"

　　The reason for the size difference was easy to see．Once a subordinate fish grows to within 5-10% of the size of its larger competitor，it causes a fight which usually ends in the smaller goby being driven away from the group．More often than not，the evicted fish is then eaten up．

　　It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish．Whether they did so voluntarily，by restraining how much they ate，was not clear．The research team decided to do an experiment．They tried to fatten up some of the subordinate gobies to see what happened．To their surprise，the gobies simply refused the extra food they were offered，clearly preferring to remain small and avoid fights，over having a feast．

　　The discovery challenges the traditional scientific view of how boss individuals keep their position in a group．Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves，so keeping their competitors small．

　　While the habits of gobies may seem a little mysterious，Dr．Wong explains that understanding the relationships between boss and subordinate animals is important to understand how hierarchical（等级的）societies remain stable．

　　The research has proved the fact that voluntary dieting is a habit far from exclusive to humans．"As yet，we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature，" the researchers comment．"Data on human dieting suggests that，while humans generally diet to improve health or increase attractiveness，rarely does it improve long-term health and males regularly prefer females that are fatter than the females' own ideal．"

“Most experiences of absent-mindedness ,forgetting where you left something or wondering why you just entered a room , are caused by a simple lack of attention, ” says Schacter. “You’re supposed to remember something, but you haven’t encoded（编码） it deeply.”

　Encoding, Schacter explains, is a special way of paying attention to an event that has a major impression on recalling it later. Failure to encode properly can create troublesome situations. If you　put your mobile phone in a pocket, for example, and don’t pay attention to what you did because you’re involved in a conversation, you’ll probably forget that the phone is in the jacket now hanging in your cupboard.  “Your memory itself isn’t failing you, ” says Schacter, “Rather, you didn’t give your memory system the information it needed.”  http://wx.jtyjy.com/

　Lack of interest can also lead to absent -mindedness. “A man who can recite sports statistics from 30 years ago, ” says Zelinski, “ may not remember to drop a letter in the mailbox.”Women have slightly better memories than men, possibly because they pay more attention to their environment, and memory depends on just that.

　　“Visual cues（ 视觉提示 ）can help prevent absent--mindedness, ”says Schacter, “But be sure the cue is clear and available. ”If you want to remember to take a medicine with lunch, put the pill bottle on the kitchen table—don’t leave it in the medicine box and write yourself a note that you keep in a pocket.

　　Another common experience of absent - mindedness: walking into a room and wondering why you’re there. Most likely, you were thinking about something else. “Everyone does this from time to time, ”says Zelinski. “The best thing to do is to return to where you were before entering the room, and you’ll likely remember.”

1.The writer of the passage thinks that encoding properly is very important because ________.

　　A. it enables us to recall something from our memory

　　B. it slows down the process of losing our memory

　　C. it helps us understand our memory system better

　　D. it helps us to get back to where we were

2.One possible reason why women have a little better memories than men is that________.

　　A. they rely more on the environment

　　B. they have a wider range of interests

　　C. they have an unusual power of focusing their attention

　　D. they are more interested in what’s happening around them

3.Why can a note in the pocket hardly serve as a reminder? ________.

　　A. It will easily get lost

　　B. It is out of your sight

　　C. It’s not clear enough for you to read

　　D. It might get mixed up with other things

4.From the last paragraph we can learn that________.

　　A. repetition might help improve our memory

　　B. memory depends to a certain extent on the environment

　　C. we’d better return to where we were if we forget things

　　D. we should think about something else while doing one thing

5.The passage is mainly about ________.

　　A. the memory system of persons

　　B. a way of encoding and recalling

　　C. the causes of absent-mindedness

　　D. the impression of the environment on memory

A
Sports can help you keep fit and get in touch with nature.However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses（球场） in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.

That“Monday morning feeling”could be a crushing pain in the chest which leaves you sweating and gasping for breath. Recent research from Germany and Italy shows that heart attacks are more common on Monday mornings and doctors blame the stress of returning to work after the weekend break.
　The risk of having a heart attack on any given day should be one in seven, but a six-year study helped by researchers at the Free University of Berlin of more than 2, 600 Germans showed that the average person had a 20 percent higher chance of having a heart attack on a Monday than on any other day.
　Working Germans are particularly not protected against attack, with a 33 percent higher risk at the beginning of the working week. Non-workers, by comparison, appear to be no more at risk on a Monday than any other day.
　A study of 11, 000 Italians proved 8 a. m. on a Monday morning as the most stressful time for the heart, and both studies showed that Sunday is the least stressful day, with fewest heart attacks in both countries.
　The finding could lead to a better understanding of what is the immediate cause of heart attacks, according to Dr Stefan Willich of the Free University. “We know a lot about long-term risk factors such as smoking and cholesterol（胆固醇）but we don’t know what actually causes heart attacks, so we can’t give clear advice on how to prevent them, ”he said.
　Monday mornings have a double helping of stress for the working body as it makes a rapid change from sleep to activity, and from the relaxing weekend to the pressures of work.
　“When people get up, their blood pressure and heart rate go up and there are hormonal（内分泌）changes in their bodies, ”Willich explained. “All these things can have an unfavorable effect in the blood system and increase the risk of a clot（血凝块）which will cause a heart attack.”
　“When people return to work after a weekend off, the pace of their life changes. They have a higher workload, more stress, more anger and more physical activities,”said Willich.
【小题1】Monday morning feeling, as this passage shows, ________.
