关于天气的英语语法总结,

什么叫“关于天气的英语语法”总结啊?是时态吧,语法还有形容词、名词等
造几个句子,应该是这样吧!
一般现在时：现在雨下得很大.It is raining hard now.
一般过去时：昨天下了雨：It was raining hard yesterday.
一般将来时：According to the weather report,there will be a heavy rain tomorrow.
过去将来时：According to yesterday's weather report,there would be a heavy rain.
只要把各种时态的结构搞清楚,自己造句不是难事,关于天气的语法就会搞清楚了.
