ENGLISH GRAMMAR

Every day we use lots of energy. Just look

around you. Out on the street. Cars, taxis,

trucks, and buses all use gasoline. And lots

of it! Sometimes there are so many cars that

they cause a traffic jam. Have you ever seen

a traffic jam? That's when a lot of cars are

moving very slowly. And sometimes they

are stopped. But as their motors run, they

continue to use gasoline. And look up. There's

the traffic helicopter reporting on the traffic

jam and using a lot of gasoline!

Sometimes while you're waiting to move, you hear a siren. It might be a fire engine or an ambulance. How can they get by in an emergency? It's almost impossible.

So, what can we do? We can use public transportation. Lots of people traveling together on a train or a subway can save energy. People can also form carpools and drive together to work or school.

And how about electricity? We use a lot of

electricity every day. We use it in our homes

 to light our rooms and to run our appliances.

And what about elevators and escalators?

All tall buildings have them. When you walk

down the stairs, you save energy. And when

you walk up the stairs, you save even more,

We should turn off the lights when we leave

a room and use the stairs to save electricity.

And we should use public transportation and carpools to go places. We should always be thinking about ways to save energy.

What is Wind Power?

Do you like to fly a kite on a windy day? The kite

lifts off the ground and goes high in the sky. A pinwheel spins in the wind. Wind blows the seeds from a dandelion. The kite, the pinwheel,

and the seeds are all moved by wind power.

Wind power is a source of energy. Getting power from wind is nothing new. 

They made sailboats. Later, they built windmills. Wind turns

the blades on a windmill. People used windmills to pump

water or turn grain into flour. Today, we can use wind power

to make electricity. Electricity powers many things in our

homes, such as lights and refrigerators.

Sources of Energy

Wind blows all over the world. Today, however, very little of our energy comes from wind. Where does our energy come from? Most of it comes from oil, natural gas, and coal. These energy sources are

called fossil fuels.

Fossil fuels are made from the remains of things that lived millions of years ago. People burn fossil fuels to make energy. A power plant, for example, burns coal to make electricity. After fossil fuels are used up, they are gone forever. Fossil fuels are nonrenewable resources. They cannot be replaced. Wind power is a clean source of energy. It does not cause pollution. We will not run out of wind. It is a renewable resource. Wind does not stop blowing after it is used for energy.

Multiple Choice

Fossil fuels can not be.............. after being used.

• updated

• made

• renewed

How Wind Power Works

Today, modern windmills called wind turbines make electricity. A turbine looks different from the old type of windmill. Its blades look

like airplane propellers. The tall part is usually hollow and made of metal instead of wood. Most turbines have three blades. Often, many turbines are built close together to form a wind farm.

• metal

• gold

• wood.

Wind Power in the Future

"Today, we get most of our energy from fossil fuels. Wind power, however, is the fastest-growing renewable energy source. Wind may be one important source of energy in the future. Energy from water and the sun might also help reduce our need for fossil fuels. Using these renewable energy sources will help make our planet a cleaner, greener place to live!
