城市道路上的井盖被偷,有人掉下去,或者骑自行车的人车轮被卡在井口,人被摔得“半死”。这是我们经常听到或见到的事情。“城市黑洞”现象当你驾驶着自己的爱车,快速行驶在宽阔的公路上,突然发现前方路面有一个没有井盖的井口,你一定会被这个“黑洞”惊出一身冷汗,一天的好心情也许因此而随之烟消云散了。
The manhole cover on the city road was stolen, someone fell, or the cyclist’s wheel was stuck at the wellhead. The man was slammed into half-dead.

The good mood of the day may be dispelled.
