pop music playwright classical music country musicvocalist/pop singer the blues light music conductorSECTION ATextual organization:General statement: We all listen to music on three separate planesPlane1: the sensuous planeFurther explanation:Listening to music for the sheer pleasure of the musical sound itself and hearing music without thinking, without considering it in any way.Plane2: the expressive planeFurther explanation:All music has an expressive power, all music has a certain meaning behind the notes and that meaning behind the notes constitutes what the piece(of music) is saying and what the piece is about.Plane3: the sheerly musical planeFurther explanation:Besides the pleasurable sound of music and the expressive felling that it gives off, music does exists in terms of notes themselves and of their manipulation.Yet while listening to music most listener:are not sufficiently conscious of the third plane./tend to listen on one or the other of the three planes.The author concludes that:We listen to music in all three ways/and on all three planes at the same time.The theme of the text:When listen to music ,one should be a more conscious and aware listener—not someone who is just listening, but someone who is listening for something.Understanding long/difficult sentences1. doesn’t need to think anything but just enjoy.2. cause/effect3. the meaning of music4. typical music commentator advocating this idea that music should have meaning.5. discourage wherever and whenever it is met.SECTION BVocabulary studyA)b c a g d h f eB)1. so to speak（可以这么说）2. strive for（争取/奋斗）3.be alive to（对…敏感）4.take into account（考虑/重视）5.sensitive to（灵敏的）6.carried away （忘乎所以）mensurate with(以…相当)8.give off（发出）9.self-evident （不言而喻的）10.clarity（清楚/明晰）C)1.other2.dancing3.else4.stage5.like6.over7.discover8.event9.for 10.madeSECTION CGRAMMAR REVIEWA)1.

UNIT71. Several leading modern business leaders seem, surprisingly, to downplay the importance of strategy. You can make too much fuss about strategy, they imply--- you have a few clear options; just choose one and get on with it. is it really that simple?2. “Strategy is straightforward---just pick a general direction and implement like hell.”Jack Welch, for example---the chairman and CEO of the USA’s General Electric Company; the man who grow the company from a market capitalization of $27 billion to a $140 billion, making GE the largest and most valuable company in the world. he must know a thing or two about strategy. But here’s what he says: “In real life, strategy is actually very straightforward. You pick a general direction and you implement like hell.”Or Allan leighton, the man who was recruited by Archie Norman to help res cue the UK’s ailing Asda supermarket chain, and went on to build the company into one of Britain’s most successful retailers. “Strategy is important,” says Leighton, “but it is a compass, not a road map. It tells you in which direction you are heading, but the important bit is how you get there.”Or Louis Gerstner, the man who rescued IBM in the 1990’s when the struggling mainframe supplier was about to be driven into extinction by the new, smaller and more agile personal computer manufacturers. “It is extremely difficult to develop a unique strategy for a company; and if the strategy is truly different, it is probably highly risky. Execution really is the critical part of a successful strategy. Getting it done, getting it done right, getting it done better than the next person is far more important than dreaming up new visions of the future.”3. So strategy is simple. And having an ingenious new strategy is less important than carrying it out successfully. In fact it might be dangerous. It that right?Let’s look at one last quote from Mr. Welch. “When I became CEO in 1981, we launched a highly publicized initiative: be number one or number two in every market, and fix, sell or close to get there. This was not our strategy, although I’ve often heard it descri bed that way.It was a galvanising mantra to describe how we were going to do business going forward. Our strategy was much more directional. GE was going to move away from businesses that were being commoditized toward businesses that manufactured high-value technology products or sold services instead of things.”Grand strategy versus strategy4. I would argue that these CEO’s blue chip corporations are taking a slightly Olympian view of the concept of “strategy.” Let’s call what hey are talking about “grand strategy” a strategy, but in the overarching sense, like the American car industry saying that they are going to move out gas-guzzlers and into smaller, more fuel-efficient models. 1.一些领先的现代企业领导人似乎，奇怪的是，淡化战略的重要性。

Unit 7Exploration is an important survival strategy in evolution.探索是进化过程中一个重要的生存策略。

The migration of expansive species depends on exploring their immediate or distant surroundings for new food sources or safe habitats; it can also come as a result of population pressures or environmental changes.数量不断扩张的物种的迁移有赖于对临近或遥远的新的食物来源或安全的栖息地进行探索，这是人口压力或是环境变化的结果。

The human species has added another reason for exploration, namely curiosity. This intellectual urge to explore the unknown led the great European explorers to the Americas, Australia and Antarctica between the fifteenth and seventeenth centuries.而人类还增加了另外一个探索的原因，即好奇心。

这种对未知事物进行探索的思想冲动引领着伟大的欧洲探险家们在15世纪到17世纪之间来到了美洲，澳大利亚和南极洲。

Inquisitiveness about nature is also the driving force behind humans exploring the polar caps, climbing mountain peaks and diving into the abysses of the oceans.对大自然的好奇心同样也是人类探索极地冰冠，攀登山峰和潜入海底背后的驱动力。
