知识点03  提纲

知识点04  范文

Dear Mr. Mayor,

    I’m from No. 5 Middle School. I like our city, but the environment around here is getting worse and worse.

    First, there is white pollution everywhere in the city. People use too many disposable things, such as plastic cups, bottles, bags and lunch boxes. People throw them away after only using them once.

I think that people should try to use their own cups, lunch boxes and chopsticks instead of disposable things.

    Second, there has been haze in the city in recent years. That’s because there are more and more cars on the road and they give off too much waste gas. People should use public transportation more. It’s a good idea to take buses and use shared bikes. I think the government should encourage more people to use new energy vehicles.

    I hope the environment in your city gets better and better.

Yours sincerely,

                                                           Wang Lei

尊敬的市长先生：，

我来自第五中学。我喜欢我们的城市，但周围的环境越来越差。

首先，城市里到处都是白色污染。人们使用太多一次性物品，如塑料杯、瓶子、袋子和饭盒。人们只使用一次就把它们扔掉了。

我认为人们应该尽量使用自己的杯子、饭盒和筷子，而不是一次性物品。

第二，近年来该市出现了雾霾。那是因为路上的汽车越来越多，而且它们排放的废气太多。人们应该更多地使用公共交通工具。乘公共汽车和共享自行车是个好主意。我认为政府应该鼓励更多人使用新能源汽车。

我希望你们城市的环境越来越好。

谨上，王磊

【谚语俗语】

1．Save water，waste of shame．节约用水，浪费可耻。

2．Don't let our tears become the last drop of water on the earth．不要让我们的眼泪成为地球上的最后一滴水。

3．Sharing the same sky，a total of a soil retaining．同顶一片蓝天，共护一方水土。

4．Mother nature is good，also cold butcher．大自然是善良的慈母，同时也是冷酷的屠夫。

Make the world greener

Hello, everyone! I am happy to give a speech calling on all of us to care about the environment.

Everyone can make small changes in their lifestyle and help reduce pollution and waste.

First, we can ride bikes or walk to school rather than going to school in parents’ car, as this can help reduce air pollution. Second, we should turn off the lights when going out as well as turn off the tap when we brush our teeth. Besides, we shouldn’t use plastic bags when we go shopping, because plastic is harmful to the environment. Last but not least, we need to plant more trees and flowers to make the environment greener.

If we keep doing this, I believe the environment will be better and better. Let’s do everything we can to live a green life and protect our planet.

Yours faithfully,

Zhang Hua

【答案】例文：

Dear Sir or Madam,

I don’t agree to build an automobile factory in my hometown. Here are my opinions.

First of all, if a factory is built, it will require a large piece of land, and some of the original trees will be cut down, which will destroy the ecosystem there. Secondly, if a factory is built, a large amount of waste water and harmful gases will be produced in the production process. When these gases are discharged into the air, they will cause harm to human beings, animals and plants. If the waste water is discharged into the river, it will pollute the water source, and we will never see the clear river again.

I hope that the government should carefully consider whether to build factories. Protecting the environment is the responsibility of all of us. The earth is the home of every one of us. We should protect it.

【答案】例文：

Going Green Starts with Small Things

Everyone can make small changes in lifestyle and make a difference to reduce pollution and waste.

First, you’d better ride a bike or walk to school, because it’s a green way which doesn’t pollute the air. Second, saving electricity, water and food is necessary. You should turn off the light when going out. Turning off the tap when you brush your teeth can save a lot of water. What’s more, don’t use plastic bags when you go shopping, plastic is harmful to the environment. Last but not least, we need to plant more trees and flowers to make the environment more beautiful.
