为你的课堂写指令的英语短文

万千世界，种种东西都包含着颜色，就连课堂也不例外.
一.红色的课堂--数学课.
为什么说数学课是红色的课堂呢？因为我们对数学课是像圣火一样热情.数学老师是一位优秀的老师，她上课幽默生动.看到有同学在开小差，决不会用骂的方式去说他们，总会用婉转的方法去提醒他们.你说，这样好的老师上的课，我们怎么会不喜欢？
二.橙色的课堂--语文课.
你可别看语文老师平时总板着脸，一副极其严肃的样子.其实，她上课也挺幽默的，但幽默的程度却次于数学老师.每当我们班的同学开小差的时候，她总会讲一个故事，以从故事的道理“教育教育‘他们.日长天久，同学渐渐地爱上了语文课.
三.白色的课堂--英语课.
对于上英语课，我们班的同学的意见大同小异.总的来说，我们对于英语，一个字就是闷，两个字就是很闷，三个字就是非常闷.上英语课，就像一张白纸，既没图画，又没颜色，简直是活受罪.
我们班的课堂颜色是这样的，你们班的呢？

This summer, I went to my hometown and found it changed a lot．
In the past, my hometown was a very beautiful one．A river running through our village used to be very clean with many fish in it．Tall and straight trees, beautiful flowers and green grass could be seen everywhere．People lived a poor but simple life．
Nowadays, however, with the development of modern society, people are living a “happy” life．Many tall buildings are found on both sides of the river, but the river has been badly polluted．More boats can be seen on the river, but there are few fish swimming in it．The living environment is becoming worse and worse!
I think it’s time that we should take action and do something to protect our living environment．
