According to a recent study at the Insight Meditation Society in Barre, Massachusetts, three months of training in this kind of meditation causes a marked change in how the brain allocates attention. It appears that the ability to let go thoughts that come into mind frees the brain to attend to more rapidly changing things and events in the outside world. Expert mediators are better than other people at catching such fast-changing stimuli, like facial expressions. The study provides evidence for changes in the workings of the brain with mental training. People can learn and improve abilities of all sorts with practice, everything from driving to playing the piano. The study has shown that meditation is good for the brain. It appears to reduce pressure and promote a sense of well-being. In an experiment, 17 volunteers with no meditation experience in the experimental group spent three months meditating 10 to 12 hours a day. A control group also with no meditation experience meditated for 20 minutes a day over the same period. Both groups were then given the tests with two numbers in a group of letters. As both group looked for the numbers, their brain activity was recorded. Everyone could catch the first number. But the brain recordings showed that the less experienced mediators tended to grasp the first number and hang onto it, so they missed the second number. Those with more experience gave less attention to the first number as if letting it go, which led to an increased ability to grasp the second number. This shows that attention can change with practice. Just ask Daniel Levision, who meditated for three months as part of the study.” I am a much better listener,” he said. “I do not get lost in my own personal reaction to what people are saying.” 56. The underlined word “them” in Paragraph 1 refers to ________. A. feelings B. minds C. people D. thoughts 57. Meditations manage their daily tasks better because they ________. A. are given less pressure B. allocate their attention better C. have more stimuli for life D. practice them more frequently 58. The study proves that ________. A. meditation improves one’s health B. brain activity can be recorded C. human attention can be trained D. mediators have a good sense of hearing B As the summer comes, the exhausted consumers start paying attention to the latest cooling devices(仪器)in the market. With the competition rising ,buying an air conditioner (AC) is no longer a big deal; moreover the easy finance schemes make it a device for every life. Design Though it carries the standard design for AC, yet it looks elegant(优雅的) when fixed on your wall. As AC is exposed to exterior(外部的)climate, it is bound to get damaged and bring maintenance cost if not taken proper care of. But Haier has solved this problem by providing an anti-corrosion(抗腐蚀的)body to all its AC. It has a remote control which provides you with ultimate flexibility and you can operate it from every corner of your room. Key Features It’s proved that this AC steals the show by offering 1tonne cooling capacity at the EER of 9.47. This means it operates at low power and thus helps you save great energy, and consequently it wins popularity with customers. The rotary compressor(旋转式压缩机)is the secret behind its smooth and silent operation, which makes it suitable for public and silent areas. Core Information Apart from the above features, it attracts consumers by its unique anti-bacterial filters(过滤器), which act as a favor to your health by destroying the harmful germs and bacteria and make you breathe very clean air. Advantages and Disadvantages The anti-bacterial filters prove to be a favor for our respiratory system(呼吸系统). When compared to other famous brands such as Samsung, Onida, and LG, it offers great functions at a very friendly price. However, it lacks some additional filters which are seen in other expensive brands like Electrolux EA12SCRLA1. Conclusion It’s a masterpiece(杰作) due to its silent operation and uniform(均速的)cooling. Thus, if you desire cool air, then just switch to this AC and feel the magic. 59. It can be inferred from the passage that __________. A. most customers are not satisfied with the latest AC B. the price of AC has been lowered due to the fierce competition C.

A. learns key technologies secretly B. puts theories into practice scientifically C. attracts more attention and praise D. shows some advantages and disadvantages 61. Which of the following plays an important role in guaranteeing our health? A. The anti-corrosion body. B. The remote control system. C. The rotary compressor. D. The anti-bacterial filters. 62. Compared with other brands, Haier AC’s biggest advantage lies in ________. A. the standard design B. the low maintenance cost C. the best after-sales service D. the great functions at a low price C If you gaze(凝视)through a telescope at a distant galaxy(星系), it may glow brightly with the light of hundreds of millions of stars. Despite(尽管，不顾) all that light, most scientists think that at the center of a big galaxy lies something very dark: a black hole. A black hole is a region of space with gravity so strong that nothing can escape, not even light. (责任编辑：admin) |
