重点讲解
1. “ considering ”在这里是个介词，后面接名词。意为“鉴于，考虑到”。 eg. she is very active, considering her age. 就她的年龄来说，她是够活跃的。 “considering”也可以做连词，后面接个句子。 eg. considering he's only just started, he knows quite a lot about it. 考虑到他只是刚刚开始，他对此的了解已经不少了。
2. responsible for 是……的原由;为……负责 eg. while you are responsible for your duties, you cannot do everything by yourself. 当你对你的任务负责时，你就不能亲自做每一项事情。 eg. after all, if a person is not responsible for their own brain, who is? 毕竟，如果一个人不能为自己的大脑负责，谁能呢?
