職稱英語(yǔ)歷年真題《理工A》閱讀理解精選

  The Northern Lights

  The sun is stormy and has its own kind of weather. It is so hot and active that even the Sun's gravity 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 coming from the Sun is called the solar wind. The more active the Sun, the stronger the solar wind.

  The solar wind constantly streams toward the Earth, but don't 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 the Earth. When a large blast of solar wind crashes into the Earth's 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'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 (北極光) 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 but they can also pulsate (跳動(dòng)), flicker (閃爍), or even move like waves.

  During solar maximum, 5 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 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!

  A. disappearance of the Sun's gravity.

  37. What happens when solar wind comes to the Earth?

  A. A protective magnetic field is formed at the same time.

  B. It is trapped in magnetic belts around the Earth.

  C. It destroys the protective magnetic field surrounding the Earth.

  D. It breaks magnetic field lines and does severe damage to the Earth.

  38. The Northern Lights are created when__________.

  A. atomic particles fall to the Earth and collide with atmospheric gases.

  B. the magnetic field lines fail to reconnect.

  C. the electrons falling to the Earth shine in different colors.

  D. oxygen and nitrogen are separated from the atmospheric gases.

  39. Which of the following statements is true of the Northern Lights?

  A. Their movement is slow enough to be observed with the eyes.

  B. People cannot see them unless traveling to Alaska or Canada.

  C. They are very close to the ground.

  D. They are very long and thick.

  40. What is the author's tone toward the Northern Lights?

  B. Sarcastic.

  C. Sharp.

  D. Appreciative.

  答案與解析:

  36.C。推理題。題干:太陽(yáng)風(fēng)的形成是因?yàn)開_________。由關(guān)鍵詞solar wind可找到第一段的第二、三句“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 coming from the Sun is called the solar wind.”,即“能源從太陽(yáng)向地球以帶電粒子流的形式流逝,以大約每小時(shí)一百萬(wàn)英里的速度移動(dòng)。這些粒子被稱為等離子,來(lái)自太陽(yáng)的等離子流叫作太陽(yáng)風(fēng)。”由此可知太陽(yáng)風(fēng)與能量流有關(guān),故選C。

  37.B。推理題。題干:當(dāng)太陽(yáng)風(fēng)到達(dá)地球的時(shí)候會(huì)發(fā)生什么?根據(jù)第二段的第三句“The charged particles become trapped in magnetic belts around the Earth.”可知,帶電粒子變成被困在地球周圍的磁帶。由此可知B正確。

  38.A。推理題。題干:當(dāng)__________時(shí),就形成了北極光。根據(jù)第三段的最后一句話“As the electrons fall into the Earth,they collide with gas molecules in the atmosphere,creating flashes oflight in the sky.”可知,由于電子粒落到地球,它們與大氣中的氣體分子發(fā)生碰撞,產(chǎn)生的光線在天空中閃爍。根據(jù)第四段所述的“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.”可知,每種大氣氣體發(fā)光的顏色不同,氧氣和氮?dú)獍l(fā)出的光不同,這些不同顏色的光芒,構(gòu)成了夜空中的北極光。綜上所述,可知A正確。

  39.A。細(xì)節(jié)題。題干:下列有關(guān)北極光的敘述,哪項(xiàng)是正確的?根據(jù)倒數(shù)第二段的第二句 “The movement of the aurora across the sky is usually slow enough to easily follow with your eyes but they can also pulsate(跳動(dòng)),flicker(閃爍),or even move like waves.”可知,通常足夠慢的極光劃過天空的運(yùn)動(dòng)很容易被眼睛看到。由此可知A正確。.

  40.D。態(tài)度題。題干:作者對(duì)北極光持什么態(tài)度?根據(jù)文章的最后兩句話“We hope you are able to travel to far-north places like the Arctic Circle and see the Northem Lights at least once during your lifetime.We know you will never forget it!”可知,作者建議讀者可以到北極圈以北的地方看到北極光,你將永遠(yuǎn)不會(huì)忘記。
