这段说得不错，值得推广

It often rains in summer,so it is a rainy season.
There is a lot of rain in  summer.
Look,it is raining.
我们也是类似这么说的  rain（下雨、雨水）rainy（下雨天）

这个总结不错，很适合我们班的学生们！感谢！

名词形容词还是动词由句子含义决定，一般来说，be动词后面表天气就用形容词，如It's rainy today.
There be句型表有许多雨水就用名词，如There  is a lot of rain here in summer.
出现在没有be动词也没有其他动词的句子中一般就是用作动词了，如It often   --------in spring.Does it often -------here?  同意这样说

It often rains in summer,so it is a rainy season.
There is a lot of rain in  summer.
Look,it is raining.
这段说得也不错，值得推广。

大家都解释很清楚了，不用俺在罗嗦拉。

把单词放在句中 举例说明 就行啦

It often rains in summer,so it is a rainy season.
There is a lot of rain in  summer.
Look,it is raining.
说的很好

It often rains in summer,so it is a rainy season.
There is a lot of rain in  summer.
Look,it is raining
这种教法可使用

其实关键搞清rain这个单词就行了  它既是动词又是名词 作名词是不可数的
