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
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".
