影视对白：

The chip attached to the pigeon recorded a distance covered of 12 miles. Assuming a straight line of flight, the bird was released anywhere along this 12-mile radius. And that zone includes the billiard shop where jesse worked.
鸽子腿上的芯片显示飞行距离为12英里。假设是直线飞机，放飞地就在半径12英里的范围内。包括了Jesse工作的桌球房。

今天我们要学的单词是：a straight line of flight 一架直线飞机

a straight line: 直线 ；一条直线

例句：

This is why a person may walk in an arc when he sets out in a straight line.
这就是一个人在出发时本来是想走的直线，结果却走成了一条弧线的原因。

Although the optimal user path is a straight line from search and results to customization and purchase, the interface offers several detours from this route.
尽管最佳的用户路径是从搜索和结果到定制和购买的直线路径，但该界面却提供了一些迂回的路径。
