When something is perilous, it is very dangerous — not a small risk, but the kind where someone could get hurt or a plan could fall apart. People use it more in writing, news, and stories than in everyday talk.

When something is perilous當某件事是perilous的時候，it is very dangerous它非常危險——not a small risk不是小小的風險，but the kind where someone could get hurt or a plan could fall apart而是那種可能會有人受傷，或計畫整個垮掉的危險。People use it more in writing, news, and stories大家比較常在書寫、新聞和故事裡用這個字，than in everyday talk而不是在日常對話裡。

A child is more likely to say “that’s so dangerous”; a book might say “a perilous journey across the mountains.” It is often about real physical danger (perilous seas, a perilous climb). People also stretch it a little, on purpose, for a situation that could easily turn into trouble: a perilous lead in a game, a perilous political choice.

A child is more likely to say “that’s so dangerous”小孩比較可能會說『that's so dangerous（好危險喔）』；a book might say “a perilous journey across the mountains.”一本書可能會寫『a perilous journey across the mountains（一趟橫越山區的險途）』。It is often about real physical danger它常常是在講真實的身體危險（perilous seas, a perilous climb像perilous seas驚險的海域、a perilous climb驚險的攀爬）。People also stretch it a little, on purpose大家也會故意把這個字用得更廣一點，for a situation that could easily turn into trouble用在很容易演變成麻煩的情況：a perilous lead in a game, a perilous political choice像遊戲裡a perilous lead（岌岌可危的領先）、a perilous political choice（凶險的政治選擇）。

Though actually, when they stretch it that far they are being a bit dramatic — the core picture is still “this could go badly wrong.”

Though actually不過其實，when they stretch it that far they are being a bit dramatic用到那麼誇張的時候，其實是講得有點戲劇化——the core picture is still “this could go badly wrong.”核心的畫面還是『this could go badly wrong（這可能會出大差錯）』。
