The brontosaurus was one of the largest of all dinosaurs.

雷龙是所有恐龙中最大的一种。

At the end of the workday, a whistle would blow and you'd jump out your window and slide down the tail of a brontosaurus and right into your car like Fred Flintstone.

班的时候公司哨响，需要跳出办公室窗户，顺着一条雷龙的后背和尾巴滑去，正好坐到的车里，就像《摩登原始人》里的场景一样。
