有人问： 有这样一道题：

(1)The street is about twenty kilometers_____.

A.from north to south

B.from the north to the south

C.from the east to west

D.from the west to east

所给答案为A，为什么不是B?

表方向时: north, south, east, west一般不用定冠词the，再如：

(2)Which way is south ?

(3)Set the compass to north and then work out the direction we have to walk.

(4)East or west , home is best.

表方向的词如是副词，自然也用零冠词，如：

(5)The ship is sailing west .

(6)The window faces south .

表方向的名词如特指地域，其前则应用定冠词the,如：

(7)The sun rises in the east and sets in the west .

(8)It is cold in the north .
