It's our duty to look after our home- the earth! To (保护) our environment, we should do something in our (日常的) life. Firstly, we should (分开) the waste into two parts-things we can (回收利用) and things to throw away. Secondly, we must try our best to use (瓷器) cups and cloth bags. While shopping, we'd better use baskets instead of (塑料的) bags. Thirdly, don't always think of buying new things. Some (用过的) things are also as good as new ones. For example, we can use both sides of paper, remember to learn to save resources. Of course, we can't hope for a (快速的) change, but let's take (措施)from now on. Repeat these things every day, and we can surely (减少) waste. Day by day, the environment will be better and greener. We can live more healthily, and our home can be saved. Do you think so?

Suraj was playing games with his friends after the science class. As soon as his maths teacher came to the classroom, he (move) back to his place.

And it happened (sudden). Suraj wet his trousers! He felt very ashamed (羞愧的). He imagined what his friends would think about him. They would talk about it for (year) and he would become a joke for everyone in the class.

In the front the classroom, the math teacher was looking for someone (answer) the questions. She watched Suraj for a while and called his name.

Suraj got very nervous and he didn't know to do. He was afraid that everybody would see his wet trousers he stood up. At this time, Kiran, who sat next to Suraj, handed (he) a bottle of water and asked him to calm down. When he reached out for the water, Kiran accidentally dropped it. Then all water fell on Suraj.

The classmates and teacher were (surprise) and hurried to help. After school, Suraj thanked Kiran with all his heart. Kiran smiled and said,

"Hey I know buddy! I experienced same a few months ago. I wet my trousers!"

Energy is everywhere. We use energy to move the mouse for a computer, to jump and shout and walk and run.

Electricity is a form of energy and this is what powers the TV, hairdryer, mobile phone, fridge, electric toothbrush and more! Our growing need for energy is one of the problems facing the world today, because producing electricity also produces pollution.

Here are some simple ways to make a big difference when using electricity.

On or off? Turning off televisions and computers by a remote controller will leave a little red light on the screen, which still uses electricity, even though they might look like they've been turned off.

Lights off! Turning lights off when you're not in the room can save a lot of energy.

Fridge door closed. The fridge is an important part of the kitchen. It keeps food fresh, cool and healthy! But it takes a lot of energy to keep cool, so don't leave the fridge door open or put hot things inside.

Use the sun's energy. An increasing number of people are fitting solar panels to their homes. They create electricity from sunlight, which can then be used to power their homes. Solar heating panels make hot water, reducing the need for electricity or gas to heat water.

World Environment Day is held each year on June 5. It is one important way through which the United Nations encourages worldwide awareness and action for the protection of our environment and gets political attention and action, World Environment Day promotes some ways to improve the earth's environment.

●What do people do? World Environment Day is celebrated in many ways in countries such as Kenya, New Zealand, Poland, Spain and the United States. Activities include concerts, tree planting, and clean- up campaigns.

●Background World Environment Day was established by the UN General Assembly in 1972. Two years later, in 1974 the first World Environment Day was held with the theme" Only One Earth". Even though World Environment Day celebrations have been held annually since 1974, in 1987 the idea for rotating the centre of these activities through selecting different host countries began.

●Symbols The main colours for this event are natural colours. These colours are often green, brown and blue. Images of the earth's natural features, such as snowy mountains, clean beaches and unpolluted rivers are used to improve campaigns on the day.
