Let's Do Something to save Our Environment
We all live on the earth. The earth is our home. We have only one earth. We must take care of it. If we harm it, we will have a terrible end. There are three problems in our earth, which are pollution,disaster and illness.
It's our duty to protect our environment.So everyone should do something to save our environment. First, we should save every drop of water, such as turning off the taps after using it and recycling the water. For example, we can water the plants and clean the rest room with our used water.Second, we should save energy, such as turning off the lights when we leave, doing more walking, more bicycling and less driving and so on. Third, we should ask our government to control the pollution from the factories.
Let's act now to save our environment. If everyone makes a contribution to protecting the environment, the earth will become much more beautiful.

假如你是某中学的同学，将参加主题为“Let's ride bicycles”的英语演讲比赛活动，请撰写一份演讲稿。
Good morning, everyone, I'm Li Hua from Xingguang Middle School. The topic of my speech is "Let's Ride Bicycle". As is known to all, with the improvement of people's living standard, cars have become a popular meansof transport, bringing great convenience to our life. However, they have also caused some problems such as pollution and traffic jams. How can we solve the problem then? As far as I'm concerned, riding bicycles is a good solution. For onething, bicycles don't need any petrol andthey are energy-saving. Foranother, bicycles are environmentally friendly because they don't give off waste gas. What's more, riding bicycles is a good way to exercise and itis beneficial to our health. Therefore, let's take the responsibility to build up a low carbon city by riding bicycles. Come on and joinus! Thank you!
假设你是李华。近日，你的英语笔友Jack听说你们学校正在开展“建设节约型社会(Construction of an energy-saving society)”主题活动，发来邮件请你介绍一下你对活动的看法和建议。请结合实际情况，用英语给Jack回复邮件。
Glad to receive your E-mail. As you know, there has been an activity of "Construction of an energy-saving society" in our school recently. I think it is of vital importance because our society is facing the increasing danger of lack ofenergy. Many reasonable suggestions are given during the activity. In my opinion, there're many things we can do. In our daily life, we shouldn't waste any food or paper.It is also advisable to refuse to use disposable chopsticks and plastic bags. Besides, I think the government should make it a rule that those used textbooks should not be thrown away when we graduate from school, because most of the books are in good condition and can be recycled. Actually, there are quite a lot that we can easily do: such as, try to take buses orride bicycles instead of driving cars. All of these will definitely help to construct an energy-saving society.
