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. |

Naps-short sleeps during the day-may improve memory, experts said recently. New research conducted by brain researcher Avi Karni of the University of Haifa in Israel explores the possibility that naps help lock in sometimes long-term memories. "We still don"t know exactly how memory system works during sleep, but the results of this research suggest it is possible to speed up memory consolidation (巩固)," Karni said. Long-term memory refers to memories that stay with us for years, such as "what" memories-a car accident that happened yesterday-or "how to" memories, such as one"s learned ability to play the pianos. Karni, also one of the authors of the study published in a recent issue of the journal Nature Neuroscience, instructed participants to learn a difficult set of finger games, then divided the study subjects into two groups: one that napped for an hour, and one that didn"t. The people who took an afternoon snooze showed obvious improvement in their performance by that evening. "After a night"s sleep the two groups were at the same level, but the group that slept in the afternoon improved much faster than the group that stayed awake," Karni said. And the study also showed just how much faster a 90-minute nap could help lock in long-term memories. "Daytime sleep can shorten the time "how to" memory weakens and forgetting starts,"Karni said, "Instead of 6 to 8 hours, the brain consolidated the memory during the 90-minute nap." |
1. We can learn from the article that ________. |
A. the new research has discovered the memory process during the sleep B. taking a nap helps improve both long-term and short-term memories C. Karni"s findings are based on comparisons between two groups of participants D. people who take a nap will never forget "how to" skills once they are learned |
2. The underlined word "subjects" in paragraph 3 probably mean________. |
A. the people being tested in the study B. the people carrying out the study C. the topics being discussed in the study D. the areas of knowledge being studied |
3. The text is most probably taken from ________. |
A. a newspaper report B. a library guide C. a project handbook D. a science site |

A screen door (纱门) allows for an open view while at the same time affording a degree of privacy. 1 , communication between parents and their child away at college should have 2 in expressing viewpoints but, at the same time, it should demonstrate a respect for privacy. Staying in touch with each other is important because without 3 , there is no connection and worry can take over. All involved should try to be 4 in listening to, understanding and dealing with special concerns or needs that arise whether they may be from the student, parents or friends. For the 5 student adjusting well at school, calls to home can be infrequent. This is not necessarily a cause for parents to 6 . While parents are naturally 7 about what their child is up to, the majority of students are busy getting 8 to their new home, making new friends and 9 to new schedules and activities. The fact is that without any ill intention on purpose, they can spend little time thinking about home and they may not appreciate the degree of their parents" 10 curiosity. For the student who is not adjusting well at school, calls to home will probably be mademore 11 . This circumstance can bring a 12 period for both parent and child. For the parents at home, it can be terribly 13 to sense. their child is unhappy. It is difficult to judge how we should react to this challenge: as 14 , we want to bring our children home to the safety of our 15 ; in our parent-teacher role, we want to 16 the ties and allow our child the opportunity to 17 it on his/her own. For the student away at school, unhappiness can be lonely and frightening and in some cases, it can lead to depression and illness. There is a sense of 18 for some homesick students who fear that Mom and Dad will 19 their inability to cope with the new environment. This is especially true when the homesick one sees classmates adjusting somewhat effortlessly. No matter what the circumstances are that have created 20 , communication between parent and child must remain open, honest and in balance. |

Frederic Mishkin, who"s been a professor at Columbia Business School for almost 30 years, is good at solving problems and expressing ideas. Whether he"s standing in front of a lecture hall or engaged in a casual conversation, his hands are always waving and pointing. When he was in graduate school, one of his professors was so annoyed by this constant gesturing that he made the young economist sit on his hands whenever he visited the professor"s office. It turns out, however, that Mishkin"s professor had it exactly wrong. Gesture doesn"t prevent but promotes clear thought and speech. Research demonstrates that the movements we make with our hands when we talk form a kind of second language, adding information that"s absent from our words. It"s learning"s secret code: Gesture reveals what we know. It reveals what we don"t know. What"s more, the agreement (or lack of agreement) between what our voices say and how our hands move offers a clue to our readiness to learn. Many of the studies establishing the importance of gesture to learning have been conducted by Susan Goldin-Meadow, a professor of psychology at the University of Chicago. "We change our minds by moving our hands," writes Goldin-Meadow in a review of this work. Particularly significant are what she calls "mismatches" between oral expression and physical gestures. A student might say that a heavier ball falls faster than a light one, for example, but make a gesture indicating that they fall at the same rate, which is correct. Such differences indicate that we"re moving from one level of understanding to another. The thoughts expressed by hand motions are often our newest and most advanced ideas about the problem we"re working on; we can"t yet absorb these concepts into language, but we can capture them in movement. Goldin-Meadow"s more recent work strews not only that gesture shows our readiness to learn, but that it actually helps to bring learning about. It does so in two ways. First, it elicits (引出) helpful behavior from others around us. Goldin-Meadow has found that adults respond to children"s speech-gesture mismatches by adjusting their way of instruction. Parents and teachers apparently receive the signal that children are ready to learn, and they act on it by offering a greater variety of problem-solving techniques. The act of gesturing itself also seems to quicken learning, bringing new knowledge into consciousness and aiding the understanding of new concepts. A 2007 study by Susan Wagner Cook, an assistant professor of psychology at the University of Iowa, reported that third-graders who were asked to gesture while learning algebra (代数) were nearly three times more likely to remember what they"d learned than classmates who did not gesture. |

It doesn"t come as a surprise to you to realize that it makes no difference what you read or study if you can"t remember it.You just waste your valuable time. 1 One dependable aid that does help you remember what you study is to have a specific purpose or reason for reading. Why does a clerk in a store go away when your reply to her offer to help is, "No, thank you.I"m just looking."? Both you and she know that if you aren"t sure what you want, you are not likely to find it. But suppose you say instead, "Yes, thank you.I want a pair of sun glasses." She says, "Right this way, please" 2 If you choose a book, "just looking" for nothing in particular, you are likely to get just that-nothing. But if you do know what you want, you are almost sure to get it.Your reasons will vary; they will include reading or studying "to find out more about", "to understand the reasons for" and "to find out how". 3 Before you start to study, you say to yourself something like this, "I want to know why Stephen Vincent Benet happened to write about America".Because you know why you are reading or studying, you relate the information to your purpose and remember it better. 4 At least two important processes go on at the same time. As you read, you take in ideas rapidly and accurately. But at the same time you express your own ideas to yourself as you react to what you read.You have a kind of mental conversation with the author. This additional process of thinking about what you read includes evaluating it, relating it to what you already know, and using it for your own purposes. 5 One part of critical reading, as you have discovered, is distinguishing between facts and opinions.Facts can be checked by evidence, Opinions are one"s own personal reactions.Another part of critical reading is judging sources.Still another part is drawing accurate inferences. |
A. Maybe you have already discovered some clever ways to keep yourself from forgetting. B. It is important for students to have a positive attitude to their study. C. You remember better when you know what you" re reading. D. In other words, a good reader is a critical reader. E. It"s quite the same with your studying. F. Reading is not one single activity. G. This is the way it works. |
