There's a channel in the middle of the old street to help rainwater flow away.

旧街道的中央有一条沟渠来排放雨水。

I wormed my way along the roadside ditch.

我慢慢地路边的沟渠向前走。

The rain has filled up the ditches again.

雨水又把沟渠给灌满了。

A ditch diverted water from the stream into the fields.

一条沟渠把水从河里引向田间。

The running water from the mountain top eroded a gulley along the slope.

从上流下的水在坡上冲蚀出一条沟渠。

It is that treat the person who love you chillily,digging a ditch nobody can jump out.

用自己冷漠的心，对待爱你的人，掘出了一条无法跨越的沟渠。

The stream from the mountain slope fretted a channel through the soft earth along the mountain foot.

"坡上下来的小溪流侵袭松软的土地,脚跟形成了一条沟渠。"
