water streak的意思|示意

A white streak below, to his right, marks how high water rises during the wet season.

他右边下面的一条白色条纹，表明了雨季期间水位上涨到多么高。

The bright yellow arcs that streak the marine cloud layer are ship tracks—clouds that form when water vapor condenses onto the myriad tiny pollution particles in ship exhaust.

划过海洋云层明亮的黄色弧线是船舶的航迹——那是些由水蒸汽与船舶排放出来的无数污染微粒凝结而成的云。

A vast expanse of sand stretches away out of sight on every side, with here and there a streak, as of water, running across, though sometimes what gleams like water is only sand.

眼前是向四周扩散开去一望无垠的沙滩。沙滩上仿佛四处可见潺潺的流水，事实上，有时像水一样闪闪发亮的，也只是沙子。
