2017職稱英語理工閲讀真題

勤奮靠的是毅力，是永恆。文學家説，勤奮是打開文學殿堂之門的一把鑰匙;科學家説，勤奮能使人聰明;而政治家説，勤奮是實現理想的基石;而平凡的人則説，勤奮是一種傳統的美德。可見，勤奮富有了多麼巨大的底藴與魅力，人類如果丟棄了它，絕對不行。以下是小編為大家搜索整理的2017年職稱英語理工閲讀真題，希望能給大家帶來幫助!更多精彩內容請及時關注我們應屆畢業生考試網!

　　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), 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!

36. The solar wind comes into being as a result of__________.

A. disappearance of the Sun's gravity.

B. unpredictable weather of the Sun.

C. fast flow of energy away from the Sun.

D. a stream of particles being blown away.

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?

A. Indifferent.

B. Sarcastic.

C. Sharp.

D. Appreciative.

36.C。推理題。題幹：太陽風的形成是因為__________。由關鍵詞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 e particles are called plasma，and the stream of plasma coming from the Sun is called the solar wind.”，即“能源從太陽向地球以帶電粒子流的`形式流逝，以大約每小時一百萬英里的速度移動。這些粒子被稱為等離子，來自太陽的等離子流叫作太陽風。”由此可知太陽風與能量流有關，故選C。

37.B。推理題。題幹：當太陽風到達地球的時候會發生什麼?根據第二段的第三句“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。題幹：當__________時，就形成了北極光。根據第三段的最後一句話“As the electrons fall into the Earth，they collide with gas molecules in the atmosphere，creating flashes oflight in the sky.”可知，由於電子粒落到地球，它們與大氣中的氣體分子發生碰撞，產生的光線在天空中閃爍。根據第四段所述的“Each atmospheric gas glows a different en and nitrogen glows red and green and nitrogen glows these various colors glow and dance in the night sky,they create the Northern Lights and the Southern Lights.”可知，每種大氣氣體發光的顏色不同，氧氣和氮氣發出的光不同，這些不同顏色的光芒，構成了夜空中的北極光。綜上所述，可知A正確。

39.A。細節題。題幹：下列有關北極光的敍述，哪項是正確的?根據倒數第二段的第二句 “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)，flicker(閃爍)，or even move like waves.”可知，通常足夠慢的極光劃過天空的運動很容易被眼睛看到。由此可知A正確。.

40.D。態度題。題幹：作者對北極光持什麼態度?根據文章的最後兩句話“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 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，你將永遠不會忘記。
