请教各位同仁,如何让学生掌握"rain , rainy"的区别.对于何时该作名词用,何时该作动词用,何时又该当作形容词.学生一团雾水.对大家的帮助不甚感谢!

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?

rain是名词、动词雨的意思
We have much rain here.
It is raining.
rainy是形容词一般形容天气!
It's rainy here in winter.

我们用这样几个句子讲的:
It often rains in summer,so it is a rainy season.
There is a lot of rain in  summer.
Look,it is raining.
先让学生理解句意,再加以点拨.

说的不错哦

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.
很棒哦，谢谢！

确实应该跟学生说得透彻详细一点，现在语篇教学挖掘这些难点很重要。

谢谢，学生这个错误率确实很 高

先和学生说单词意思 再是词性
最后从举例句说明
