tunnel front的意思|示意

Thick pipes protrude from the ceiling, and a window in the front room opens onto nowhere, just another gray tunnel wall beyond it.

粗壮的管道从天花板上突出来，前屋的窗户外不过是另一堵灰色的隧道墙壁。

In this illusion, the circle placed further back in the tunnel appears larger than that placed near the front.

在这个错觉中，在隧道后方远处的圆看起来比在隧道前面的圆大一些。

Sit in front and you get a picture-window forward view as the train tears through a dark tunnel.

当列车穿越漆黑的隧道，靠前坐，你可以将落地玻璃窗外的景色一览无遗。
