Low-carbon life is good for everyone.
To help with the environment, I always walk or ride a bike to school instead of taking a car. Besides, I will try to use things that can be recycled and I never forget to turn off the lights when I leave the classroom. I think it’s my duty to live a low-carbon life. And even the simplest activities can make a real difference to the environment. So I suggest we should reuse books as long as possible. And we’d better not spend much money on expensive clothes.
If everyone does something for the environment, I believe the earth will be a better place.
8. 节约用水
水是生命之源。随着水资源的短缺，节约用水是我们每个人的责任，请以此为话题写一篇不少于80字的短文。
★ 范文
As we know, water is very important to man, we can’t live without water. The amount of water which is suitable to drink is less and less. But some people don’t care about it. They waste a lot of water in their daily life. Even worse, they pour dirty water into rivers. They throw rubbish into rivers, too. Many rivers and lakes are seriously polluted.
Something must be done to stop the pollution. And I think it’s a great shame to waste while millions are in great need of water. I think what we can do is that we have to save every drop of water as possible as we can. For example, we must turn off the tap immediately after we use it. We can use a basin to wash our hands and faces. It’s also a good idea to encourage my friends and family members to join me! Only in this way can we live happily. If we don’t save water, the last drop of water will be a tear-drop of us.
I believe if everyone makes a little effort, we can make a big difference.
