A s具有相似的含义, like (像〜)。我可以理解,演讲者说每个人都会有一天死亡,这就是as/like it should be的样子( as/like it should be )。 A s功能用来强调,特别是在本演讲中,用来强调死亡对人很重要的特定观念。示例: Our family rule is that everyone must celebrate Christmas together. And that is as it should be. (我的家人有一个规则,每个人都应该一起过圣诞节,而本来(如果是圣诞节的话)应该一起过圣诞节。)示例: The constitution protects the human rights of all citizens, as it should. (宪法必须保护所有公民的人权。)
