Roses carpeting the ground; Thrushes, orioles, warbling sound: Swing me low, and swing me high, To the warm clouds of July.

玫瑰花铺满了整个大地；画眉、黄鹂，婉转的叫声, 把我摇高又摇低，摇进七月温暖的云朵里。

Dust particles, especially if coated by pollution, act as condensation nuclei for warm cloud formation and as efficient ice nuclei agents for cold cloud generation.

尘埃颗粒，尤其是被污染覆盖的尘埃颗粒， 充当暖云形成的凝结核和冷云生成的有效冰核剂。
