關于節約的英語兩分鐘演講稿(5篇)
我們從小被教育，節約要從小處做起，從一粒米一滴水做起。下面是小編為大家整理的關于節約的英語兩分鐘演講稿，如果大家喜歡可以分享給身邊的朋友。
Dear teachers and students,
hello everyone!
The theme of my speech this time is to save water and start from small things. World Water Day is March 22, but how much do you know about water?
Maybe you don't understand, let me tell you something. One cannot lack water. Water accounts for 65% of the body weight. If a person lacks 5% of water, it will lead to confusion, even illusion. Without water, human beings can only live for about a week at most. It can be seen that people cannot lack water.
But why save water? What if we don't save water? Although the earth is covered with water, the total amount of fresh water that can be used by us is only 3/100000 in so much water. It accounts for 0.34% of the total fresh water. At present, more than 100 countries in the world are short of water. We have learned the text "The Power of Dreams". I know that many people in most parts of Africa die because they cannot drink clean water.
However, how can we save water? I have some tips for you.
1. Water resources should be recycled. For example, rice washing water can water flowers, wash vegetables and flush toilets.
2. Shorten shower time.
3. Turn off the tap.
Students, save water, start from small things, let's take action immediately.
thank you.
hello everyone!
Water makes flowers red, trees green, the earth watered, crops yellow and helps people live, so we must cherish it and save it.
You must be thirsty, right? Then you will drink water, because it is the most thirst quenching. I remember when I was in Grade One or Grade Two, I always forgot to bring water. I was thirsty! I need to drink water as soon as I get home. I feel that water is better than juice and milk.
Surely everyone will wash things? Just wash your hands. They will wash several times a day. Besides, everyone should take a bath and wash clothes. Does it all use water?
There are many more uses of water, which can help people. It is indispensable to human beings. So we must cherish it and save it.
Since we need to protect water sources and save water, we should not just talk but do nothing. For example, after washing hands, clothes and other dirty water, you can go to flush the toilet and brush mops. Turn off the faucet in time after use, and repair the faucet in time when it is broken... It is not difficult, just some small things around us.
Water is the source of life, the blood of labor, and the lifeblood of the earth. To cherish water is to cherish your life.
thank you.
hello everyone!
Water is the source of all life. Only with it can we have the breath of life. Only with it can we have a vast ocean, beautiful mountains and everything.
I can see from a piece of data that although the earth is called a "water ball" because 70% of the water is called, only 2.5% of the fresh water can be drunk. Nearly 70% of the fresh water is fixed in the ice layer in Antarctica and Greenland, and the rest is mostly soil water or deep groundwater, which cannot be used by human beings. Less than 1% of the fresh water on the earth can be directly used by human beings. Saving water is what our modern society has always advocated, and it is the modern atmosphere we should have. But it is very rare to have such an atmosphere. Water resources have been seriously damaged, crops have withered, livestock have no water, and what terrible things are happening one after another. I want to give you some suggestions:
1. When brushing your teeth and washing, do not keep the tap on all the time. You can use a mouthwash cup to catch water. According to the data, continuous drainage for 30 seconds can waste about 6 liters of water.
2. Small pieces of clothes can be washed by hand. Pay attention to washing with basin.
3. For washing machine, please put proper amount of detergent instead of excessive amount. Excessive amount will waste water.
4. Turn off the tap as soon as you see it is not tight.
Save water, start with me!
thank you.
Dear teachers and students
hello everyone!
Students, do you know what is the most important component in human body? That's water. Plants need water, animals need water, and the atmosphere, the protector of the earth, does not contain a bit of water. Everything in the world can't live without water. When it comes to saving water, some people will say that it is not just water, but there is plenty of water in the sea. In fact, you are wrong. 93% of the world's water is salt water, which cannot be drunk. Fresh water only accounts for 7%, but drinkable fresh water only accounts for 0.8%. Sea water is salt water. If we don't save water, the 0.8% water may disappear soon.
At present, 1.2 billion people around the world are facing moderate to high pressure of water shortage, 80 countries are short of water sources, and 2 billion people can not guarantee their drinking water. It is predicted that by 2025, the situation will further deteriorate. If we continue to do the same, the water shortage population will reach 2.8 billion - 3.3 billion. Therefore, only by saving water, our descendants will not worry about water shortage.
Now, do you know the importance of saving water? Only in this way can our children and grandchildren not worry about water shortage. This is also to protect ourselves! Thank you. That's the end of my speech.
Water is an important natural resource. The limited nature of water resources, the threats to their use (over-exploitation and pollution) and the imbalance in their distribution have now reached critical levels and will pose serious challenges to the international community in the coming years. More than one billion people worldwide source their drinking water from polluted founts, springs or rivers, reported the organization UNICEF on the UNs “Day of the Water” on March 22nd.
Saving water at home, in the garden, or at work, takes very little effort, but makes a BIG difference. Dripping taps can waste up to 4 litres of water a day. Replace worn tap washers for a quick and cheap way of saving water. Use the minimum amount of water required when you boil water in saucepans and kettles; that way, you’ll save energy as well as water.Lets make contribution to the environment and save water as you can.
