当喷气式飞机从高空飞过，有时其尾气会留下白色的航迹云。在特定条件下，飞机尾气还有可能产生彩虹般漂亮的航迹。一位澳大利亚的摄影师就拍到了这样的画面。
This photographer captures airplane-generated rainbows
by Francesca Street
An airplane speeds through the clouds, a trail of technicolor（色彩明艳的） contrails（航迹云） following behind, illuminating the sky in dazzling rainbow shades. This incredible moment was captured on film by Brisbane-based Australian photographer Michael Marston, who posts eye-catching aerospace imagery and video on social media.

Marston began snapping shots of airplanes about three years ago. His partner, Tracy, is a Qantas flight attendant and Marston thought it'd be pretty neat to capture a photograph of a plane she was staffing flying across the moon.
snap /snæp/ v. 拍照
shot /ʃɒt/ n. 照片
partner /ˈpɑːtnə(r)/ n. 伴侣
Qantas 是澳大利亚最大的航空公司
flight attendant /əˈtend(ə)nt/ 飞机乘务员
neat /niːt/ = good
staff /stɑːf/ v. 任职于
He started experimenting with solar and lunar photography, and soon began observing other aerospace phenomena. "I noticed that planes look very pretty when they go overhead with the right atmospheric conditions – they produce rainbows behind them, with the vapor," Marston says.
solar /ˈsəʊlə(r)/ adj. 太阳的
lunar /ˈluːnə(r)/ adj. 月亮的
photography /fəˈtɒɡrəfi/ n. 摄影
observe /əbˈzɜːv/ v. 观察
phenomenon /fəˈnɒmɪnən/ n. 现象（phenomena /fəˈnɒmɪnə/ 是复数）
overhead /ˈəʊvəhed/ adv. 在头顶（由over和head组成）
atmospheric /ˌætməsˈferɪk/ adj. 空气的、大气的（由atmosphere加后缀-ic变成形容词）
condition /kənˈdɪʃ(ə)n/ n. 状态、情况
vapor /ˈveɪpə(r)/ n. 雾气
When an airplane is flying at high altitude, there's a decrease in pressure and the temperature of the air drops, explain experts at the Institute of Atmospheric Physics at the German Aerospace Center.★ If there's enough moisture in the air, the vapor forming behind the aircraft freezes, generating ice crystals.
altitude /ˈæltɪtjuːd/ n. 海拔高度
pressure /ˈpreʃə(r)/ n. 压力
★ 这句话里explain experts就等于experts explain，因为后面的at ...是说明experts的，所以就把explain放前面了
moisture /ˈmɔɪstʃə(r)/ n. 水汽
aircraft /ˈeəkrɑːft/ n. 飞机、飞行器
generate /ˈdʒenəreɪt/ v. 产生
crystal /ˈkrɪst(ə)l/ n. 晶体、结晶
Scientists from NASA say the ice crystals form when cold air condenses（凝结） around particles from the plane's exhaust. The remarkable rainbow effect happens when the crystals are aligned at the right angle with the sun, explains NASA.

particle /ˈpɑːtɪk(ə)l/ n. 微粒
exhaust /ɪɡˈzɔːst/ n. 尾气
remarkable /rɪˈmɑːkəb(ə)l/ adj. 引人注意的
align /əˈlaɪn/ v. 排列整齐、对齐
angle /ˈæŋɡ(ə)l/ n. 角度
On June 2019, Marston shot video footage of this marvel, capturing the moment when a Qatar Airways Boeing 777 flew over Brisbane, with stunning rainbow contrails. This wasn't the first time Marston took photographs of rainbow contrails, but it's the first time he captured it on video.
shoot /ʃuːt/ v. 拍摄
footage /ˈfʊtɪdʒ/ n. 视频片段
marvel /ˈmɑːv(ə)l/ n. 令人惊叹的事物、奇迹
stunning /ˈstʌnɪŋ/ adj. 极其美丽的
The photographs and footage are so striking, they almost look like they've been doctored. They're not fake, though, Marston insists. He says he's got the raw files to prove it, and in the past, he's posted the files on his personal Facebook account to silence naysayers（唱反调的人）.
striking /ˈstraɪkɪŋ/ adj. 令人惊奇的
doctor /ˈdɒktə(r)/ v. 篡改、伪造
fake /feɪk/ adj. 假的、伪造的
raw /rɔː/ adj. 原始的、未经处理的
silence /ˈsaɪləns/ v. 使安静、使不说话
It's just a scientific curiosity, he says, albeit one that you're not likely to see clearly with the naked eye, simply because the airplane's usually so high. "It requires specialized camera equipment to capture it," says Marston, who, a few months ago, finally realized his dream of capturing the moment Tracy's aircraft passed by the moon.
curiosity /ˌkjʊəriˈɒsəti/ n. 好奇心、求知欲
albeit /ɔːlˈbiːɪt/ = although
naked /ˈneɪkɪd/ adj. 裸露的（naked eye就是裸眼、肉眼）
simply /ˈsɪmpli/ adv. 仅仅（表示强调）
specialized /ˈspeʃ(ə)laɪzd/ adj. 专门的、专用的
equipment /ɪˈkwɪpmənt/ n. 装备、器材
Marston's proud of all his atmospheric shots of airplanes, whether they're emblazoned（显眼地展示） in front of a crimson（深红的） sun, eerily（怪异地） silhouetted（显现剪影） against the moon or captured generating a technicolor burst of rainbow contrails.
burst /bɜːst/ n. 爆发、迸发
Still, he has plenty of failed attempts amongst those triumphs. "It's a bit like fishing," he says. "I enjoy the thrill of catching something – and also have the pain of going out and catching nothing. It can be rewarding and at the same time absolutely frustrating."
still /stɪl/ adv. 尽管如此
amongst /əˈmʌŋst/ = among
triumph /ˈtraɪəmf/ n. 巨大成功
thrill /θrɪl/ n. 兴奋、激动
rewarding /rɪˈwɔːdɪŋ/ adj. 带来奖赏的、令人满足的
