• The Northern LightsThe 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 (等离子体)，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 field 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，the 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 to 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 (北极光)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 (跳动)，flicker (闪烁)，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!The solar wind comes into being as a result of A disappearance of the Sun’s gravity.B unpredictable weather of the Sun.C a stream of particles being blown away.D fast flow of energy away from the Sun.

• 阅读新天地。
  　　北极是一个美丽可爱的地方，那里一年只有冬夏两季。
  　　在冬季的半年里，天气很冷，气温常在冰点以下。这时候偶然也会出现微弱的阳光，可是一阵子就过去了，所以北极的冬季是一片昏黑的。而到了夏季又刚好相反了。整季里斜射的阳光总是照耀着，平均气温在华氏36度至40度之间。这时□成千上万的海鸟都飞来了□它们在海岸的岩壁上做巢□许多海鸥□雁儿□鸠鸟□北极燕等□也都在海边捕食鱼类□
  　　北极（）寒冷，（）也有繁花似锦的时候。每年夏天，草原上处处绿草如茵，百花竞放，它们大多色泽鲜艳，惹人喜爱。光是有花的植物，就有几百种。可惜这种现象，每年只有在六月至八月，我们才可以欣赏得到。
  　　北极的天空还有一种奇异罕见的现象，那就是北极光。这种北极光，色彩缤纷，灿烂夺目。它的形状动荡不定，有时像一条银光的带子，横跨天空；有时像帘幕或挂屏；有时又闪烁着，像流星般掠过。这种千变万化的奇丽动人景色，只有在北极的晚上，才可以欣赏得到。
