什么是Live Essential

live essentials 的意思是：生活必需品。
　　1、We live now in a foreign-currency lockdown, and although the government has assured everyone that there are sufficient reserves to buy essentials such as oil, grain and medical supplies for the winter, such assurances only serve to create a further sense of unease in a people who have learnt to take such commodities for granted.

　　我们现在生活在外汇禁闭期，虽然政府已向每个人保证，有充足的外汇储备购买石油、粮食和医疗用品这样的必需品来过冬，但此类保证只是在认为这些商品是理所当然的人们中间制造了更多的焦虑感。
　　2、We probably haven't even noticed, that with each stride the civilization takes toward the ultimate development, more burdens are added to the earth that provides us with essentials to live.
　　还注意到，这与每个大步走向文明需要的发展，更多的负担的地球为了必备的生活。
