句中的 considering 不是现在分词，而是介词，意思是“考虑到”“就……而言”。它在用于此义时可以像其他介词一样，无需考虑其逻辑主语的问题。又如：

She’s very active, considering her age. 就她的年龄来说，她是够活跃的。

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。

Considering the strength of the opposition, we did very well to score two goals.  考虑到对方实力强大，我们能攻进两球已经很不错了。

Considering the injuries he’s had there can be little expectation of him winning the race. 考虑到他有伤在身，他赢得这场比赛的希望不大。

Considering she’d only been there once before, she did well to find the way. 考虑到她以前只到那里去过一次，她路还认得不错。
