I don't think it's necessary for everyone to learn first aid. Most people won't ever be in a situation where they need to use it. Usually, professional medical help is close by and can handle emergencies better. Also, some people might panic and not remember what to do, even if they have been trained. Plus, learning first aid can take a lot of time and money, which could be spent on other important things.
我不認為每個人都有必要學習急救。大多數人不會遇到需要使用急救的情況。通常,專業的醫療救助就在附近,能更好地應對緊急情況。此外,有些人可能會驚慌失措,即使他們已經接受過訓練,也可能不記得該怎麼做。此外,學習急救可能需要花費大量的時間和金錢,而這些資源可以用於其他重要的事情。
