点一下不认识的单词。
On November 14, 2017, a bright fireball meteor appeared in the sky above the Dolomite Alps in Italy. The photo was taken from a mountain pass near the village of La Villa, Alta Badia. The sky showed soft pink colors of the fading twilight, and snowy mountain peaks were visible.
Above the village lights, the constellation Ursa Major hung over the northern horizon. The fireball meteor flashed from east to west under the Big Dipper shape in Ursa Major. The photo captured this meteor by chance during the camera’s exposure.
Many people in Europe saw this major fireball meteor. It became one of the most reported fireball events ever for the American Meteor Society and the International Meteor Organization. The meteor’s path over Germany matched the Northern Taurid Meteor Shower, which happens every November and comes from dust of Encke’s comet.

难句解析
- 1
The fireball meteor flashed from east to west under the Big Dipper shape in Ursa Major.
介词短语“under the Big Dipper shape in Ursa Major”容易误解，意思是“在大熊座里的北斗七星形状下方”。整句：这颗火流星从东向西划过，位置在大熊座的北斗七星下方。
- 2
The photo captured this meteor by chance during the camera’s exposure.
“by chance”是固定短语，意为“偶然地”；“during the camera’s exposure”指相机曝光期间。整句：照片是在相机曝光时偶然拍到这颗流星的。
- 3
The meteor’s path over Germany matched the Northern Taurid Meteor Shower, which happens every November and comes from dust of Encke’s comet.
“which happens every November and comes from dust of Encke’s comet”是定语从句，修饰“the Northern Taurid Meteor Shower”。意思是：这场流星雨每年11月出现，来自恩克彗星的尘埃。
