in和on都可以用。in the street是指在街上。on the street是特指在街上的地面有关的东西。
基本上二者都可以用,但除了以下几种特定的用法:
1)专指「在户外」时就要用in the street。
如:It is dangerous to be in the street after dark.醉卧街头时,当流浪儿等当然是在户外,所以也是用in,而交通工具也是在户外走,所以也是用in。
2)当做在能力上「难以相比」时,也是用in,如in the same street.
如:Her clothes are not in the same street as yours.
3)专指街的地面时,就要用on,如丢纸屑,还有走在街面上时也用on。
4)广为人知时,也是用on。
如:Sue put it on the street, and now everyone knows.
5)专指华尔街日报时,就要用on。
如:I heard on the Street today that bank stocks are headed up.
7)指打折後的最低价,也是用on。
如:It lists at $2200 and can be got for about $1600 on the street.
