同学你好~
同学提问的时候要说一下是哪一册哦
这道题的答案是课文原文。

Mr. James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst. Pinhurst is only five miles from Silbury, but Mr. Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr. Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private 'telephone' service.

这里都要用现在完成时，表示已经做了的事情，对现在有一定影响。
1. 2 两处不要受到空格的限制，要按照课文的顺序写。
这三处都强调已经完成的事情和对现在的影响，即买了汽车修理部（不得不弄电话），买了鸽子（开始使用鸽子），开始了电话服务（无错号之虞）。

祝同学学习进步~
