六月已到來，夏天這個旅遊的季節又即將開始。你也許去過很多地方，可我想阿拉斯加的極光可能你還想去領略一番。下面這篇雙語閱讀爲你詳細介紹阿拉斯加的極光。
Alaska is known for its dark cold winters and long daylight summers. People venture there for its beautiful scenery， majestic vistas and to witness its spectacular light show virtually every night of the year. "Witnessing the northern lights is spectacular. It's awe inspiring because you can't really explain what they are and why they are there," a visitor said.
阿拉斯加以其夜長晝短的陰冷冬季與長日照的夏季而著名。人們冒險來到這裏觀賞它美妙的景色、壯麗的風光，並親眼看看一年中幾乎每晚都會出現的'極光奇觀。“目睹北極光宛如身臨仙境，奇幻之至，既興奮又令人敬畏，因爲你無法解釋它們是何物，爲何而來，”一位遊客說。
In ancient times， mythological gods were credited with this creation. But these mysterious lights get their powerful glow from the same awesome force that gives our planet life.
在古代，人們認爲是傳說中的神仙創造了這種景象。但實際上，這種神祕之光的強度光亮來自於同樣賦予地球以生命的令人敬畏的力量。
The sun is the source of energy for everything on planet earth，all life，all weather，and all activitythat we know. Explosions and solar storms on the surface of the sun send charged particles known as solar winds hurtling towards earth. When they reach the earth's magnetic field the energy is transferred into visual light around the earth's Polar Regions. Realize the earth has magnetic field lines that loop out intospace from the northern hemisphere to the southern hemisphere，arching away from the earth and it is those magnetic field lines that organize the solar storms that cause it to create auroras.
太陽是地球上萬物的能量之源，包括我們知道的所有生命、所有天氣和所有的活動。太陽表面的爆炸和太陽風暴，把帶電粒子(即所謂的太陽風)猛烈射向地球。當它們到達地球磁場之後，能量便在地球極圈地帶轉化成可視的光線。要知道，地球上的磁場線以環形在空間從北半球拋向南半球，呈拱形覆蓋於地球上空，而正是這些磁場線對於太陽風暴的作用形成了極光。
While scientists know the cause of the aurora，exactly how it affects earth is still in question. Though infrared cameras have captured solar storms，the aurora remains a mystery.
雖然科學家知道了極光的成因，但是它究竟如何影響地球仍是一個疑問。儘管紅外線攝像機能夠捕捉到太陽風暴，而極光依然是一種神祕之物。
For creating the planet's greatest nighttime light show，the aurora makes our list at number one.
因爲創造了地球上最偉大的夜光之舞，極光在我們的名單上排名第一。
From the spitting lava of Kilauea，to the raging rapids3 of the Colorado，the natural wonders of the worldare dynamic4 proof of this spectacular planet we call Earth. But ultimately it's our curiosity of theirexistence that's the most wondrous thing of all. And that is our honor to bear witness to the planet's finestlegacy the Ultimate5 Ten Natural Wonders.
從基拉韋厄火山噴涌而出的岩漿，到科羅拉多滔滔的激流，這些世界自然奇觀生動地證明了我們稱之爲“地球”的這個星球是多麼獨特、美麗。然而最終而言，所有當中最精彩的還是我們對這些景觀的好奇心。能夠見證這個星球上最好的遺產——十大自然奇觀，確實是我們的榮幸。
