There are all kinds of colors in our life, and my favorite color is green, because it symbolizes hope and life.
在我们生活中有各种各样的颜色，其中我最喜欢的颜色就是绿色了，因为它象征着希望和生命。
Whenever I see green, I think of the green blackboard in the classroom and the grass just growing in spring. They are looking at the world seriously and curiously. There are willow branches that just grow young leaves by the river. They are dancing with the wind.
每当我看见绿色时，我就会想起教室里绿色的黑板，想起了春天刚刚长出来来的小草，它们正在认真地、好奇地看着这个世界。还有在河边刚刚长出小嫩叶的柳枝，它们在随风着跳着优美的舞蹈。
Many of the vegetables we eat every day are also green. My mother always let me eat some green vegetables, which are good for our health.
我们每天吃的许多蔬菜也是绿色的。我的妈妈总会让我吃些绿色的蔬菜，说对我们的身体特别好。
Whenever summer comes in the north of China, everyone will go to the supermarket to buy big green watermelons, turn on the air conditioner at home, and eat watermelons to relieve fever.
每当我们北方的夏天到了，大家都会到超市里面买绿绿的大西瓜，在家里开着空调，吃着西瓜解热。
In addition, if there are no green trees in the world, there will be no fresh air, because the trees will absorb all the carbon dioxide we spit out and replace it with fresh air.
还有如果世界上没有绿色的大树就不会有新鲜的空气，因为大树会把我们吐出来的二氧化碳都吸收掉，换成新鲜的空气。
Green is also a sacred color. It reminds me of my uncle of the Chinese people's Liberation Army, who guards China's border and our motherland every day. During the Chinese new year, they can't go home. They have been guarding the border for five or ten years and have never seen their parents or relatives. They are the greatest people in the world.
绿色也是神圣的颜色，它不禁让我想到中国解放军叔叔，他们每天都守护着中国的边疆，保卫着我们的祖国。在过年的时候，他们都不能回家，他们守卫边疆五年、十年也见不到父母和亲人。他们是这个世界上最伟大的人。
Green has another function! It can protect our eyesight and relax our eyes. The reason why the blackboard is green is that it won't hurt our eyesight. A little more green can protect our eyes!
绿色还有一个作用呢！它就是可以保护我们视力、放松眼睛。黑板之所以是绿色的，是因为绿色不会伤害我们的视力，多看一点绿色还可以保护眼睛呢！
This is my favorite color!
这就是我喜欢的颜色！
