WHERE ARE WE?
 
Laurance- Where on earth are we?
 
Soony- Judging by all the traffic, I'd say we're near the heart of the downtown area.
 
Laurance- What did I do wrong? Did I take a wrong turn?
 
Soony- I'm not sure, but I think that you turned left when you should have turned right.
 
Laurance- Well, now the problem is how to get back onto the main highway.
 
Soony- Well, if I may offer a suggestion... Why don't you stop and ask a policeman?
 
Laurance- Yeah, yeah, yeah, I think I see one up there in the next block.
 
注解:
on earth:(口语中用于疑问句加强语气)究竟,到底,全然.
heart of the downtown area: heart=center; downtown area指繁华的商业区.
If I may offer a suggestion:直译为"如果我可以提个建议的话".
