1、 2022年职称英语理工类AB级复习资料笔记 (50)11 分析文章标题：The Northern Lights(北极光)2直接解题：考试大论坛1. The Suns gravity（引力） is too (太.而不能.)weak(弱的， 虚弱的) to keep its plasma（等离子体） from （阻挡/防止.）flowing（流淌） to the Earth.A. right B. wrong C. not mentioned1B 细节题。 利用问题句中的特征词（the Suns gravity, the Earth ）及细节信息词(plasma) 共同作为答案线索， 在文章中查
2、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（活泼的） that even(甚至) the Suns gravity （引力）cannot hold （掌握）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）e
3、lectrified（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 coming 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
4、热， 如此的活泼， 以至于太阳的引力无法掌握住其大气层”。依据第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挡其大气层中的等离子体流向地球的主要缘由不是太阳引力的问题，而是由于太阳过于活泼， 太热了。2. The Earth is quite（相当，非常） safe（安全的） with（带有） a magnetic field （磁场）surrounding（围绕) it to protect（爱护.以防止/避开.） it from the attack(攻击/攻击) by the solar wind（太阳风）.A. right B. wrong C. not
5、mentioned来源：2A 细节题。问题句说“四周带有磁场的地球是非常安全的，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(magnetic 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 Suns gravity cannot hold its atmosphere in check! Energy flows
6、 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 coming from the Sun is called the solar wind. The more active the Sun, the stronger the solar wind.The solar wind
7、constantly （不断地）streams（流） toward the Earth, but dont worry（担忧） because（由于） a protective（爱护的） magnetic fields surrounds（围绕） our planet. The same magnetic field that makes your compass point north also steers the particles from the Sun to the north and south poles. The charged particles become trappe
8、d in magnetic belts around the Earth. When a large blast of solar wind crashes into the Earths magnetic field first gets squeezed and then the magnetic field lines break and reconnect.(以下为其次十四讲内容)考试大(Examda。com)3. Some scientists（科学家） are worrying about （正在担忧 ）the possible （可能的）disappearance（消逝） of
9、the Earths protective（爱护的） magnetic field （磁场）in the future（将来）.A. right B. wrong C. not mentioned3C 细节题。利用问题句中的特征词（ the Earth ）及细节信息词(scientists, magnetic 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消失，因此推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 cons
10、tantly streams toward the Earth, but dont worry because a protective magnetic fields surrounds our planet. The same magnetic field that makes your compass point north also steers the particles from the Sun to the north and south poles. The charged particles become trapped in magnetic belts around th
11、e Earth. When a large blast of solar wind crashes into the Earths magnetic field first gets squeezed and then the magnetic field lines break and reconnect.The breaking and reconnecting of the magnetic field lines can cause atomic particles called electrons trapped in the belts to fall into the Earth
12、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 gl
13、ow 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 with your eyes
14、 but they can also pulsate, flicker, or even move like waves. 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 fo
15、rmed 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 travel to far-north places like the Arctic Circle and see the Northern Lights at least once during your lifetime. We know you will never forget 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消失，因此推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 Earths 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
