　　下面在线为同学们整理了雅思阅读辅导：使用环境对发明的限制，供各位考生参考。

　　阅读段落

　　In order to track temporal hours during the day, inventors created sundials, which indicate time by the length or direction of the suns shadow. The sundials counterpart, the water clock, was designed to measure temporal hours at night. One of the first water clocks was a basin with a small hole near the bottom through which the water dripped out. The falling water level denoted the passing hour as it dipped below hour lines inscribed on the inner surface. Although these devices performed satisfactorily around the Mediterranean, they could not always be depended on in the cloudy and often freezing weather of northern Europe.
