The United States is divided into telephone dialing areas.
Each area has an area code. It is a three-digit number. You use this number to dial long distance calls. For example, you want to call 555-2364 in South Carolina. But you live in Utah. You must dial 1 first and then the area code. It is 803. so you must dial 4.
When you do not know an area code, you can use the area code map in the telephone book. The map divides the United States into time zones. Notice that when it is 1:00 in California, it is 4:00 in Michigan.

2 1 Swooping in on a shorter woman, the sailor kissed her. 2 Acting impulsively and aiming accurately, he commanded that the camera’s shutter close at the most poignant moment. 3 Grabbing the viewer’s attention, the photo never seems to let go. 4 Closing her eyes, she was content to remain unaware of her pursuer’s identity. 5 Never knowing the truth, they glossed over the war’s miseries and romanticized life. 6 One assumes that the couple will live in a split-level home, driving big cars and producing lots of children. 3 1 Regardless of the task set by the magazine which employed him, the photographer always managed to get the best picture. 2 He kept looking for the photo, regardless of the crowds. 3 Regardless of how perfectly the pose of the sailor and the woman was arranged, he didn’t have to set up this shot. 4 Regardless of the facts, people know that life will be good from now on. 5 Regardless of what people still remember of photos in the past, this one reminds us that we felt better as a nation and as individuals. 5 1 marvel at 2 popular appeal 3 highly-/full- /well-qualified 4 perceived…as 5 exceeded…expectations Translation 6 《格尔尼卡》是西班牙艺术家巴勃罗·毕加索1937年为抗议轰炸西班牙北部一个小村庄而作的一幅巨型壁画。这幅大型壁画高3.49米，宽7.76米，展示了暴力和混乱给人和动物带来的苦难以及对建筑物的破坏。令人吃惊的是，整个壁画的色调由灰、黑、白组成，没有用鲜艳的红色来表现血腥的场面，但恐怖的景象却历历在目。画面上的人物并非用写实主义的画法来表现，而是采用立体派和抽象派的画法，但无辜平民惨遭屠杀的惨象却一目了然：一位母亲怀抱死婴，张嘴尖叫，她仰面朝天，伤心欲绝；一位士兵横尸地上，手里还紧握着一把断剑；另外三个人也都处于震惊和痛苦之中。画面中的动物——包括一匹受伤的马和一只哭泣的鸟——也都被描绘成这次屠杀的无辜受害者。毫无疑问，描绘这些扭曲变形的骇人慘象的目的就是让观众感到震惊。这种对人类悲苦惨状的描绘是对战争的残酷和荒谬的深刻控诉。 7 In the Mogao Caves in Dunhuang, the murals with “flying apsaras”are one of the most well-known artefacts. The flying apsaras in the Dunhuang Grotto Murals are a product of the intermixing of Indian and Chinese culture.

Unit 3 Language points 1 For lack of a better terminology, one might name these: (1) the sensuous plane, (2) the expressive plane, (3) the sheerly musical plane. (Para 1) The expression for lack of a better terminology is used to introduce rather inexact terms. It means since we don’t have any exact terms, I’m going to use these rather rough terms. The word sensuous suggests physical pleasure which relates to your physical senses rather than to your emotions and thoughts. A plane is a level of thought, development or existence. The word sheer is used to emphasize the amount or degree of something. The sheerly musical plane refers to the level of the musical material, melodies, rhythms, harmonies etc. The sheer pleasure (Para 2, Line 2) means great or pure pleasure. 2 The only advantage to be gained from mechanically splitting up the listening process into these hypothetical planes is … (Para 1) The word hypothetical means to be based on situations or events that seem possible rather than on actual ones. Here, the planes are not real, they are just part of a model for analysis and discussion. 3 One turns on the radio while doing something else and absent-mindedly bathes in the sound. A kind of brainless but attractive state of mind is engendered by the mere sound appeal of the music. (Para 2) To bathe means to swim or wash yourself in a bath, river or lake. To bathe in the sound means to immerse yourself in the sound, like in water. To engender means to cause a feeling or attitude to exist. The expression engendered by the mere sound appeal means to be created only by the appeal or attraction of the sound. 4 Music allows them to leave it ... dreaming because of and apropos of the music yet never quite listening to it. (Para 3) The expression apropos of means relating to; it is used to introduce something else about the subject you are talking about. The expression is derived from French, and the final -s is silent in pronunciation. Unit 3 Art for art’s sake

Not only do these young people need to overcome many difficulties, they also have to face many challenges form their parents. The differences between parents and children can be well observed in their completely different attitudes and views. First, they differ in their attitude toward life. Parents always wonder what has gone wrong with the new generation. They feel that during their time, young boys and girls were better behaved, more obedient and had greater respect for elders. Young people, on the other hand, feel that they are capable enough to learn on their own rather than lean heavily on the older generation for guidance. Young people do not like to be spoon-fed by their parents. The differences also appear in the way the two generations look at things. For example, the parents’ generation never understood Elvis and the Beatles. Because they couldn’t understan d what was going on, they were frequently opposed to them and saw rock as “the devil’s music”. Young people, however, are crazy about the modern music and would love to listen to it for a hundred times a day. Wherever they go, they’ll have their iPod with them. In conclusion, it’s very difficult for parents and their youngsters to get along due to their distinctive attitudes and the way they view things. To fill this gap, both parents and their grown children need to be more understanding to each other. Translation 9 作为美国文化价值体系的一个重要组成部分，“个人主义”受到大多数美国人的推崇。美国人认为家庭作为一个群体，其主要目的是促进家庭各成员的幸福。与许多其他文化相比，美
