Cyanide is a very strong poison. In science it is not one bottle with one name: it is a small chemical piece (carbon stuck to nitrogen) that sits inside several compounds — potassium cyanide, sodium cyanide, hydrogen cyanide gas — and those are what people usually mean.
Cyanide氰化物 is a very strong poison是一種非常強的毒藥。In science在科學上 it is not one bottle with one name它不是一種瓶子裡裝的一種東西 it is a small chemical piece它是一小塊化學結構 carbon stuck to nitrogen碳連著氮 that sits inside several compounds存在於好幾種化合物裡 potassium cyanide, sodium cyanide, hydrogen cyanide gas氰化鉀、氰化鈉、氰化氫氣體 and those are what people usually mean而這些就是大家平常說的氰化物。
A tiny amount can stop the body from using the air it breathes, so it can kill quickly. That is why crime films show a hidden “cyanide pill”: a last, terrible way out.
A tiny amount一點點的量 can stop the body from using the air it breathes就能讓身體無法使用吸進去的空氣 so it can kill quickly所以能很快致命。That is why所以 crime films show a hidden cyanide pill犯罪電影裡才會出現藏著的「氰化物藥丸」 a last, terrible way out那是最後、可怕的一條退路。
Though actually, cyanide is not only a murder tool. Some mines use cyanide compounds to pull gold out of rock, and factories use them in other work; that is still the same poison, handled with strict rules.
Though actually不過其實 cyanide is not only a murder tool氰化物不只是殺人工具。Some mines有些礦場 use cyanide compounds to pull gold out of rock會用氰化物化合物從礦石裡提煉黃金 and factories use them in other work工廠也會用在其他工作上 that is still the same poison這仍然是同一種毒藥 handled with strict rules只是有嚴格規定管理著。
Everyday English also stretches the word: people say “cyanide” for any instant, deadly chemical, even when the bottle is something else.
Everyday English日常英文 also stretches the word也把這個字用得更廣 people say cyanide人們會說「cyanide」 for any instant, deadly chemical來指任何立刻致命的化學物質 even when the bottle is something else即使瓶子裡裝的其實是別的東西。
The word belongs to news, police stories, and chemistry class. It feels technical and grave, not like chat.
The word這個詞 belongs to news, police stories, and chemistry class常出現在新聞、警方報導和化學課裡。It feels technical and grave給人的感覺是專業、嚴肅 not like chat不像閒聊。
組成From cyan- + -ide. cyan- is the “dark blue” piece (from Greek); these chemicals were named that way because they are tied to a famous blue colour. -ide is the chemistry ending for a class of compounds.
