in the corner/at the corner

【问】 I must asleep the corner， for I remember happened dur-

ing the night. (TOEFL，70. 3)

我知道B(to)是错误的，但不知应改为in the corner，还是应改为at the corner.

【答】 in the corner是指“在室内的角落里”：

1. Martin went to the telephone in the corner of the room. (London)

马丁向屋角的电话走去。

2. Those boys in the corner there must keep quiet.

那边角落的孩子们必须保持安静。

at the corner是指“在街的拐角处”。

I'll meet you at the corner of Smith Street and Beach Road. (LDCE)

我在史密斯街与海滩路的拐角处与你见面。

可见，上面的考题应将to the corner改为in the corner，而不能改为at the corner。参见onthe corner/at the corner。
