Most people who travel long distances complain of jetlag (飞行时差反应). Jetlag makes business travelers less productive and more prone 1 making mistakes. It is actually caused by 2 of your "body clock"—a small cluster of brain cells that controls the timing of biological 3 . The body clock is designed for a 4 rhythm of daylight and darkness, so that it is thrown out of balance when it 5 daylight and darkness at the wrong times in a new time zone.The 6 of jetlag often persist for days 7 the internal body clock slowly adjusts to the new time zone. Now a new anti-jetlag system is 8 that is based on proven 9 pioneering scientific research.Dr. Martin Moore-Ede has 10 a practical strategy to adjust the body clock much sooner to the new time zone 11 controlled exposure to bright light. The time zone shift is easy to accomplish and eliminates 12 of the discomfort of jetlag. A successful time zone shift depends on knowing the exact time to either 13 or avoid bright light. Exposure to light at the wrong time can actually make jetlag worse. The proper schedule 14 light exposure depends a great deal on 15 travel plans. Data on a specific flight itinerary (旅行路线) and the individual"s sleep 16 are used to produce a Trip Guide with 17 on exactly when to be exposed to bright light.

The newborn can see the difference between various shapes and patterns from birth. He prefers patterns to dull or bright solid colors and looks longer at stripes and angles than at circular patterns. Within three weeks, however, his preference shifts dramatically to the human face.Why should a baby with so little visual experience attend more to a human face than to any other kind of pattern" Some scientists think this preference represents a built in advantage for the human species. The object of prime importance to the physically helpless infant is a human being. Babies seem to have a natural tendency to the human face as potentially rewarding. Researchers also point out that the newborn wisely relies more on pattern than on outline, size, or color. Pattern remains stable, while outline changes with point of view; size, with distance from an object; and brightness and color, with lighting.Mothers have always claimed that they could see their newborns looking at them as they held them, despite what they have been told. The experts who thought that perception (知觉) had to await physical development and the consequence of action were wrong for several reasons. Earlier research techniques were less sophisticated than they are today. Physical skills were once used to indicate perception of objects-skills like visual tracking and reaching for an object, both of which the newborn does poorly. Then, too, assumptions that the newborn"s eye and brain were too immature for anything as sophisticated as pattern recognition caused opposing data to be thrown away. Since perception of form was widely believed to follow perception of more "basic" qualities such as color and brightness, the possibility of its presence from birth was rejected. Why does the newborn pay more attention to a human face than any .other kind of objects, according to some scientists？
Pronouncing a language is a skill. Every normal person is expert in the skill of pronouncing his own language, but few people are even moderately proficient at pronouncing foreign languages. Now there are many reasons for this, some obvious, some perhaps not so obvious. But I suggest that the fundamental reason why people in general do not speak foreign languages very much better than they do is that they fail to grasp the true nature of the problem of learning to pronounce, and consequently never set about dealing with it in the right way. Far too many people fail to realize that pronouncing a foreign language is a skill, one that needs careful training of a special kind, and one that cannot be acquired by just leaving it to take care of itself. I think even teachers of language, while recognizing the importance of a good accent, tend to neglect, in their practical teaching, the branch of study concerned with speaking the language. So the first point I want to make is that English pronunciation must be taught; the teacher should be prepared to devote some of the lesson time to this, and by his whole attitude to the subject should get the student to feel that here is a matter worthy of receiving his close attention. So, there should be occasions when other aspects of English, such as grammar or spelling, are allowed for the moment to take second place.Apart from this question of the time given to pronunciation, there are two other requirements for the teacher: the first, knowledge; the second, technique.It is important that the teacher should be in possession of the necessary information. This can generally be obtained from books. It is possible to get from books some idea of the mechanics of speech, and of what we call general phonetic theory. It is also possible in this way to get a clear mental picture of the relationship between the sounds of different languages, between the speech habits of English people and those, say, of your students. Unless the teacher has such a picture, any comments he may make on his students" pronunciation are unlikely to be of much use, and lesson time spent on pronunciation may well be time wasted. According to the author, pronunciation is a skill that can NOT be ______.
Most episodes 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 it deeply."Encoding, Schacter explains, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying 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 wardrobe. "Your memory itself isn"t failing you," says Schacter. "Rather, you didn"t give your memory system the information it needed."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 relies on just that.Visual cues can help prevent absent-mindedness, says Schacter. "But be sure the cue is clear and available," he cautions. If you want to remember to take a medication with lunch, put the pill bottle on the kitchen table—don"t leave it in the medicine chest and write yourself a note that you keep in a pocket.Another common episode 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. What do we learn from the last paragraph
