语篇填词
Good morning everyone present over here today. I feel honored to be selected to give a speech on pollution. In this speech, I will share with you something about footprint.
____1____ Simply understanding it is very useful to us.
Water footprint
Water is the source of life. We use water directly for drinking, cooking and washing, but we also use water indirectly for producing things such as food, paper and cloth. A water footprint tells us how much water is being used. ____2____ You can learn about how your daily habits influence your water use through the food you eat, the things you buy and even the energy you use.
Let’s read and choose the correct sentence for each blank.
B
A
It can help us come up with ways to save water.
Footprint means the influence that a person’s or organization’s activities have on the environment.
How to reduce your water footprint and carbon footprint to be greener

For example, they can walk instead of using a car.

Carbon(碳) footprint
A carbon footprint is the total amount of CO2 a person or organization produces. We can use it to understand the influence of personal behavior on global warming (全球变暖). Most people are surprised when they see how much CO2 their activities create. Then they begin to think about changing their daily habits to reduce(减少) their carbon footprints. ____3____

Tip2: Eat less meat
Meatless Monday is popular with people who want to eat less meat. The production of meat uses lots of energy and produces lots of CO2.
Tip 3: Buy less
____5____ Before you buy something, think about whether you really need it. Everyone plays a role in making a greener Earth. If you know about your footprints well, you can think up more ways to protect the environment.
To conclude this speech what we do has a great impact on the environment, animals and human lives. We as humans should take important steps for a better future. Together we can make Earth a better place.

Good morning everyone present over here today. I feel honored to be selected to give a speech on pollution. In this speech, I will try my best to explain to you all what pollution is, what causes it, and how it can be controlled.
As for ocean pollution, some of the oceans used to be so clean but now they are really dirty. Even the bottom of them is full of rubbish, and there are no more fish for fishermen to catch. The reason is that people are throwing litter into the oceans and factories are putting waste into the oceans. The air is also badly polluted. Blue skies are hardly ever seen anymore. That’s because there are more cars on the road these days and factories that burn coal also pollute the air with a lot of black smoke. Waste pollution is caused when people throw away things like wooden chopsticks, plastic bowls and plastic bags in the streets. That’s why there's too much rubbish and waste in the streets. This is turning beautiful places into ugly ones.
How to write a speech
Sample: how to write a speech.
I think everyone plays a role in protecting the environment. When we go shopping, we should use cloth bags instead of using plastic bags. Remember to throw rubbish in the bins and keep public places clean and beautiful for everyone. We should try to stop riding in cars and start riding bikes. We should also use public transportation. We can also write to the government to close down the factories that are polluting the environment.
To conclude this speech I want to say pollution has become a serious problem all around the world. Everyone must do something to make the world a better place. To protect our homeland is to protect ourselves.
Thank you for listening.
