Nature & science

87 phrases

Nature & environment29 Climate-and-environment vocabulary that shows up in every N2 news article. Watch the verb 及ぼす — 森林の伐採は、生態系に深刻な影響を及ぼす — which attaches to harm, unlike the neutral 与える. 瀕している means 'on the brink,' as in 絶滅の危機に瀕している動物, and このままでは…失われてしまう uses しまう to color an irreversible loss with regret.
Disasters29 Emergency-broadcast Japanese, where the register turns formal and clipped. 〜際は marks 'at the very moment when' — 地震が発生した際は、まず身の安全を確保してください — while 〜に伴い ties two events together: 台風の接近に伴い、交通機関に乱れが生じている. Note 直ちに (at once) and the passive 呼びかけられた, the way authorities officially 'urge' the public.
Science & tech29 These are the phrases of research papers and tech news, and the meaning lives in the connectors. に伴い in「人工知能の発達に伴い」marks a change that rides along with another change, while をもってすれば in「最新の技術をもってすれば」means "if you make use of it." N2 learners also miss をめぐって in「宇宙開発をめぐって」, which frames rivalry or debate around a topic, not merely "about" it.
