2009年职称英语理工类AB级复习资料笔记(50)

答案与解析:
  1. 分析文章标题:The Northern Lights(北极光)
  2.直接解题:
  1. The Sun’s grity(引力) is too (太...而不能...)weak(弱的, 虚弱的) to keep its plasma(等离子体) from (阻止/防止...)flowing(流动) to the Earth.
  A. right B. wrong C. not mentioned
  1.B. 细节题。 利用问题句中的特征词(the Sun’s grity, the Earth )及细节信息词(plasma) 共同作为答案线索, 在文章中查找答案相关句:
  (第一段)The sun is stormy(狂暴的,多暴风的) and has it own(自己的) kind of weather(气候,天气). It is so(如此...以至于...) hot(热的,辣的) and active(活跃的) that even(甚至) the Sun’s grity (引力)cannot hold (控制)its atmosphere(大体层, 气氛) in check! Energy(能量) flows away from (从...流出)the Sun toward(向) the Earth in a stream of (以一连串的形式)electrified(带电的) particles(粒子) that move at speeds (以...的速度)around a million miles per(每) hour(小时). These particles(粒子) are called(被称为) plasma, and the stream(流,溪, 一连串) of plasma ing from(来自) the Sun is called the solar wind(太阳风). The more active the Sun, the stronger the solar wind.
  第一个答案相关句说“太阳石如此的热, 如此的活跃, 以至于太阳的引力无法控制住其大气层”。根据第2个答案相关句可知“等离子体就是来自太阳大气层”, 由此可见造成太阳不能阻止其大气层中的等离子体流向地球的主要原因不是太阳引力的问题,而是由于太阳过于活跃, 太热了。
  2. The Earth is quite(相当,十分) safe(安全的) with(带有) a magic field (磁场)surrounding(围绕) it to protect(保护...以防止/避免...) it from the attack(袭击/攻击) by the solar wind(太阳风).
  A. right B. wrong C. not mentioned
  2.A. 细节题。问题句说“四周带有磁场的地球是十分安全的,这个磁场能防止地球受到太阳风的攻击”。 利用问
题句中的特征词(Earth )及细节信息词(magic field, solar wind) 共同作为答案线索, 在文章中查找答案相关句:
  (第一段)The sun is stormy and has it own kind of weather. (第一题答案相关句)It is so hot and active that even the Sun’s grity cannot hold its atmosphere in check! Energy flows away from the Sun toward the Earth in a stream of electrified particles that move at speeds around a million miles per hour. These particles are called plasma, and the stream of plasma ing from the Sun is called the solar wind. The more active the Sun, the stronger the solar wind.
  The solar wind constantly (不断地)streams(流) toward the Earth, but don’t worry(担心) because(因为) a protective(保护的) magic fields surrounds(围绕) our pla. The same magic field that makes your pass point north also steers the particles from the Sun to the north and south poles. The charged particles bee trapped in magic belts around the Earth. When a large blast of solar wind crashes into the Earth’s magic field first gets squeezed and then the magic field lines break and reconnect.
  (以下为第二十四讲内容)
  3. Some scientists(科学家) are worrying about (正在担心 )the possible (可能的)disappearance(消失) of the Earth’s protective(保护的) magic field (磁场)in the future(将来).
  A. right B. wrong C. not mentioned
  3.C. 细节题。利用问题句中的特征词( the Earth )及细节信息词(scientists, magic field) 共同作为答案线索, 在文章中查找答
案相关句:顺着上一题的答案位置往下查找答案相关句:scientists这个线索词连同其近义词或词义相关词,这样的信息也没有在文章中出现,因此判断该问题句的内容在文章中没有被提到。
  (第2题的答案相关句) The solar wind constantly streams toward the Earth, but don’t worry because a protective magic fields surrounds our pla. The same magic field that makes your pass point north also steers the particles from the Sun to the north and south poles. The charged particles bee trapped in magic belts around the Earth. When a large blast of solar wind crashes into the Earth’s magic field first gets squeezed and then the magic field lines break and reconnect.
  The breaking and reconnecting of the magic field lines can cause atomic particles called electrons trapped in the belts to fall into the Earth’s atmosphere at the poles. As the electrons fall into the Earth, they collide with gas molecules in the atmosphere, creating flashes of light in the sky. Each atmospheric gas glows a different color. Oxygen and nitrogen glows red and green and nitrogen glows violet-purple. As these various colors glow and dance in the night sky, they create the Northern Lights and the Southern Lights.
  Watching auroras is fun and exciting, but normally you can only see them in places far north like Alaska and Canada. The movement of the aurora across the sky is usually slow enough to easily follow wit
h your eyes but they can also pulsate, flicker, or even move like wes. During solar maximum, auroras are seen as far south as Florida, even Mexico!
  Auroras often seem to be very close to the ground, but the lowest aurora is still about 100 kilometers above the ground, a distance much higher than clouds are formed or airplanes can fly. A typical aurora band can be thousands of kilometers long, a few hundred kilometers high, but only a few hundred meters thick.
  We hope you are able to trel to far-north places like the Arctic Circle and see the Northern Lights at least once during your lifetime. We know you will never fet it!
  scientists这个线索词连同其近义词或词义相关词均没有在文章中出现,因此判断该问题句的内容在文章中没有被提到。
  4. The auroras(极光) are formed (被形成)when the electrons (电子)falling into (落入,陷入)the Earth’s atmosphere(大气层) at the poles (杆,极地)and colliding with (与...相冲突)gas molecules(气体分子) in the atmosphere.
  A. right B. wrong C. not mentioned
  4.A. 细节题。利用问题句中的特征词( the Earth’s atmosphere )及细节信息词(auroras,electrons, poles,gas molecules ) 共同作为答案线索, 在文章中查找答案相关句:
  (第2题答案相关句)The solar wind constantly streams toward the Earth, but don’t worry because a protective magic fields surrounds our pla. The same magic field that makes your pass point north also steers the particles from the Sun to the north and
south poles. The charged particles bee trapped in magic belts around the Earth. When a large blast of solar wind crashes into the Earth’s magic field first gets squeezed and then the magic field lines break and reconnect.
  (第4题答案相关句)The breaking(破坏) and reconnecting(再结合) of the magic field (磁场)lines(线,线路, 航线,绳) can cause atomic particles (原子粒子)called electrons (电子)trapped(被捕获) in the belts(地带, 带子) to fall into (落入)the Earth’s atmosphere (大气层)at the poles. As(当) the electrons(电子) fall into the Earth, they collide with (与...碰撞)gas molecules (气体分子)in the atmosphere, creating(造成, 创造) flashes(闪现) of light(光)in the sky. Each atmospheric gas(大气层的气体) glows (发光)a different color(颜色). Oxygen(氧) and nitrogen(氮) glows red and green(绿色) and nitrogen(氮) glows violet-purple(紫罗兰色). As these various(各种各样的) colors (颜色)glow and dance(跳舞) in the night sky, they create(造成) the Northern Lights (北极光)and the Southern Lights(南极光).
  Watching(观看) auroras (极光)is fun(有趣的, 有趣) and exciting(令人兴奋的), but normally you can only see them in places far north like Alaska and Canada. The movement of the aurora across the sky is usually slow enough to easily follow with your eyes but they can also pulsate, flicker, or even move like wes. During solar maximum, auroras are seen as far south as Florida, even Mexico!
