managed，prepared词义是什么

下面一段话中managed，prepared，词义是什么？rules，followed.翻译成:规则，服从对吗？These days,的意思是？These days, most food in the world is safe,这句话中主语是什么？

These days, most food in the world is safe, Laws control where food comes from. They also control how food is managed and prepared. Laws are important. But its more important to make sure he rules are followed.



我把句子翻译出来，网友对号入座即可：

These days, most food in the world is safe. Laws control where food comes from. They also control how food is managed and prepared. Laws are important. But its more important to make sure the rules are followed.

现在，世界上大部分食物都是安全的。法律法规约束着食物的来源。它们还监管着食物的管理和储备。法律法规尤为重要。但更要紧的是要确保这类法规得到实行。

most food （主语）in the world （主语之定语）is safe（系表）
