cloud表示云可数吗

cloud 表示“云”既可做可数也可做不可数名词，如A sky without a speck of cloud.万里无云；

做“云状物、一大群”讲，是可数名词，如漫天灰尘 a cloud of dust；做“阴影、暗物” 之意时是可数的，如战争的阴云the clouds of war.

The day dawned sunless and with a low cloud base.

黎明时天气阴沉，云层压得很低。

The moon was fuller than the night before, but the light was diffused by cloud.

月亮比头一天晚上更圆，但因云层遮掩而月光朦胧。

Clouds drifted across the sky.

朵朵浮云在空中飘过。

The clouds broke and the sun came out.

云开日出。
