wind意为“风”，既可作可数名词，又可用作不可数名词。［C,U］
1. 说明“风的程度或力量”时，用作不可数名词［U］,常和no, much, little, a lot of 等词语连用，无需使用冠词。如：
There isn't much wind today. 今天风不大。
jbo竟博官网There was no wind that night. 那天夜里没有风。
2. 用作可数名词［C］,其单数形式常和定冠词连用。如：
The wind is blowing very hard. 风吹的很厉害。
The wind is from the north. 现在刮的是北风。
3. 表示“某一种风”时，可与不定冠词连用，此时wind前常有形容词修饰，也可用复数形式。如：
A gentle wind was blowing over the lake. 微风掠过湖面。
Soon a wind began to blow and it became colder and colder. 不久一阵风开始刮起来，天气越来越冷了。
Cold winds blow from the north. 寒风从北方刮来。
