Scientists have come up with a theory for why time flies when you are having fun and drags when you are bored. Scans have shown that (62) of activity in the brain change depending on how we focus on a task. Concentrating on time passing, as we do when bored, will (63) brain activity which will make it seem as though the clock is ticking more (64) . The research, by the French Laboratory of Neurobiology and Cognition, is published in the magazine Science. In the study, 12 volunteers watched an image while researchers (65) their brain activity using MRI(核磁共振成像) scans. Volunteers were given a (66) of tasks. In one they were told to concentrate simply on the duration of an image, in (67) they were asked to focus on the (68) , and in a third they were asked to concentrate on both duration and color. The results showed that a network of brain regions was (69) when more subjects were paid attention to duration. It is thought that if the brain is busy focusing on many aspects of a task, then it has to spread its resources thinly, and pays less (70) to time passing. Therefore, time passes without us really (71) it, and seems to go quickly. (72) , if the brain is not stimulated in this way, it concentrates its (73) energies on monitoring the passing of time. This may make time seem to (74) , but in fact it is probably a more accurate perception of reality. (75) the researchers found that the more volunteers concentrated on the duration of the images, the more (76) were their estimates of its duration.Lead researcher Dr. Jennifer Coull said many of the areas of the brain (77) in estimating time were the same that played a key role in controlling movement, and (78) for action. She said this overlap suggests that the brain may make sense of time as (79) between movements, in much the same way (80) musicians mark time with his foot, or (81) anticipate the sound of a starter’s pistol.
Section ADirections: This section is to test your ability to give proper answers to questions. There are 5 recorded questions in it. After each question, there is a pause. The questions will be spoken two times. When you hear a question you should decide on the correct answer from the 4 choices marked A), B), C)and D) given in your test paper. Then you should mark the corresponding letter on the Answer Sheet with a single line through the center.
Michael Lewis, the author of Liar’s Poker, is the ideal writer to analyze the behavior that led to the current credit crisis. The bad news is that he is only the editor of this collection of articles. The good news is that he has not been constrained by false modesty and has chosen six of his own pieces for this book. As one would expect, they are witty, incisive and original. Mr. Lewis also contributes an introduction to each of the sections dealing with the four main panics of the last 21 years; the stock market crash of 1987, the Asian crisis of 1997-98 , the bursting of the dotcom bubble after 2000 and the current housing and banking bust. It is worth remembering, as we think the gloomy economic future, how each of the previous three crises was greeted with apocalyptic (天启的) headlines. "How many times does the end of the world as we know it needs to arrive before we realize that it’s not the end of the world as we know it" Mr. Lewis writes, in perhaps the most telling sentence of the book. The compiler’s contribution apart, the selection is a mixed bag. The aim was to give readers a flavor of sentiment before the bubbles burst, as well as analysis of the result. But the result is too much flat news stories and the book only really comes to life with the last two sections ,perhaps because the follies of dotcom valuations and subprime loans(次级抵押贷款) seem so fresh in the memory. It is hard not to miss days when Computer.com( a website for new users of technology) was able to spend 60% of its seed funding on a 90-second ad during the 2000 Super Bowl. Or when the shares of Books-A-Million, a retailer, rose tenfold within three days on the back of an upgrade to its existing website. Michael Lewis included his own pieces in the book, which was commented as not restrained by ______.
