A.in front of
B.across from
C.behind
D.next to
B
答案：B
解析：
根据答句“Cross the street and you will find it.”（穿过街道你就能找到它），结合考点中“across from”表示“在对面”，可知邮局在餐厅对面。A.in front of（在……前面）、C.behind（在……后面）、D.next to（紧挨着）均不符合语境，B.across from符合题意。

There is a car in front of the house. 在房子前面有一辆小汽车。
【例2】There are some tall trees
in front of表示“在……前面”,后面经常接表示地点的名词或者代词,反义词是behind“在……后面”。
There is a car in front of the house. 在房子前面有一辆小汽车。
【例2】There are some tall trees
in
front
of
my house.答案：in front of
解析：
根据考点，in front of 表示“在某范围之外的前面”。房子和树是两个独立事物，树在房子外部的前面，故用 in front of。
