Yes, that's exactly what my mind needs: cloudiness.

现在的我 需要让脑袋变得一片空。

The average cloudiness only about .08, and there is no sighing in the woods to betoken a big weather change.

平均云量只有大约 0.08 度，树林中没有预示着天大变化的叹息。

A lot of contaminants, like lead or arsenic, won't be obvious without tests, but some clues, like cloudiness, brown or yellow coloration, a foul odor, or an excessive chlorine smell can indicate the need to investigate further.

许多污染物，如铅或砷，如果不进就不会很明显，但一些线索，如混浊、棕色或黄色、恶臭或过多的氯味，可能表明需要进一步调查。
