It’s our duty to protect the earth. I always turn off the lights when I leave a room. While I am washing my hair,
I usually turn off the shower. Besides , if I want to shop,
I always take my own bags instead of using plastic bags.
I have decided to do more things to protect our earth,
such as recycling books and paper and reduce to use paper. It’s good for us to walk or ride bikes to school instead of driving cars. We can also plant more trees to change air around us.
Let’s take action ! Our actions can make a difference
and lead to a better future.

Homework
不少城市正在推广公共自行车，提倡人们“绿色出行，
低碳生活”。现在某英文网站就此话题征文,请根据以
下内容写推广公共单车的好处。
内容要点:
首先,骑自行车出行方便,可以随时租还(rent and return)
其次,众所周知(as we know),在上学,上班时段交通特别
繁忙(heavy traffic),如果有更多的人选择 骑自行车,
街道上就会有更少的汽车，也不会那么拥挤；
最重要的是,骑自行车几乎不会带来污染,有助于保护环境。
Now, public bikes are provided for people in many cities
in China. I think it’s a good thing.
First of all, it’s convenient for people to go out by bike.
They can rent and return the bikes at any time. Secondly,
as we know, there is heavy traffic when people go to school
or work. If more people choose to ride bikes, there will be
fewer cars and the streets won’t be as crowded as they are
now.The most important thing is that riding bikes can help
protect the environment,because there will be less pollution.
I hope more and more people can ride bikes and live a
low-carbon life.
