哨声

She could tell the approach of the milkman by the whistled notes that somehow always flatted.

她能从那总是偏低的口哨声听出送奶的到来。

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.

下班的时候公司哨声响起，你只需要跳出办公室窗户，顺着一条雷龙的后背尾巴滑下去，正好坐到你的车里，就像《摩登原始》里的场景一样。
