中国首辆无人驾驶汽车上路了。请看本报周五的报道：

    China’s first fully self-driving car has hit the road.

    On Thursday, Baidu, the “Chinese Google,” announced its autonomous car has successfully navigated a complicated route through Beijing.

    报道中的hit the road就是“离开、开始一段旅程、上路”。例如：

    We have had a lovely evening but it is time we hit the road.

    今晚我们很愉快，但是该上路了。
