请帮忙看下这两个英语句子那个是对的:

There is one next to the post office round the corner.

this one is correct

round the corner是对的
around the corner也是对的

He disappeared round the corner.
他绕过拐角就不见了。

There 's a bus stop just around the corner.
就在拐角处有一个公共汽车站。

There is one next to the post office round the corner.
There is one next to the post offoce around a corner.
这两个句子语法上都是正确的,问题不在round跟around,而在the corner跟a corner.这句话应该是回答别人问路的,中文是: 在拐角处的邮局旁边有一间(XX).很明显这里的"拐角"是特定的那个拐角,而不是随便一个,否则答了等于没答,因此用the corner..
所以第一句,There is one next to the post office round the corner.是正确的

There is one next to the post offoce around a corner.是正确的。
around 用作介词，表示在……周围
round表示圆的，不是介词

都对 round作介词就等于around

both right
