回答用It作形式主语，代指天气
语法点3 天气表达·动词-ing表“正在发生”

技巧：描述天气状态，优先用形容词
易错点突破1 频率副词的位置
一般现在时中，频率副词放实义动词前
例：She often plays the piano. (√)
频率副词放be动词/助动词后
例：He is always late for school. (√)
错误：She plays often the piano. (×)
常见频率副词：usually、often、always、never
易错点突破2 自然规律的时态选择
客观事实、自然规律必须用一般现在时
无论语境如何，均不能用现在进行时
例：The sun rises in the east. (√)
错误：The sun is rising in the east. (×)
例：Water boils at 100℃. (√)
例：Plants grow in the sun. (√)
易错点突破3 天气表达的时态搭配
现在进行时：表正在发生的天气变化
例：It’s raining now. 此刻正在下雨
一般现在时：表习惯性的天气特征
例：It rains a lot in Wuhan. 武汉经常下雨
形容词：表当前的天气状态
例：It’s rainy today. 今天是雨天
易错点突破4 瞬间动词的现在进行时
come/go/leave/arrive等瞬间动词
现在进行时可表即将发生的动作
常与tomorrow/soon等时间词连用
例：He is leaving for Shanghai tomorrow.
例：The bus is coming. 公交车快来了
技巧：表“计划、即将做”，用be+瞬间动词-ing
