I don't think it's necessary for everyone to learn first aid skills. Many people might never face a situation where they need to use them. Plus, professional medical help is usually close by, so it's often better to rely on experts. Some people might panic and not use the skills correctly, which could make things worse. Also, without regular practice, people might forget what they've learned.
我不認為每個人都需要學習急救技能。許多人可能永遠不會面臨需要使用這些技能的情況。而且,專業醫療幫助通常就在附近,所以依賴專家往往是更好的選擇。有些人可能會驚慌失措,無法正確使用這些技能,這可能會使情況變得更糟。此外,如果沒有定期練習,人們可能會忘記他們所學到的東西。
