2--I can'. The speed limit here is thirty miles an
   hour.
1--What a pity! I love going fast.
2--How do you usually get to school?
1--We never go by car! We usually walk or go by bus.
2--How long does it take you?
1--About twenty minutes by bus.

===================================
注解：

1）speed limitzhi指交通规则所限定的行车速度。
2）About twenty minutes by bus是省略句。全句应是
It takes us about twenty minutes to get to school
by bus. take作“花费”“需要”解，其后的us是间接
宾语，about twenty minutes是直接宾语。it是形式
主语，真正的主语是不定式短语to get to school by
bus.

===================================
