E. READING
I. Read the passage and decide whether the statements are TRUE or FALSE.
 Wind is moving air. We can use the energy in wind to do work. Early Egyptians used the wind to 
sail ships on the Nile River. People still use wind to move them in sailboats. In the Netherlands, people 
used windmills to grind wheat. The Pilgrims used windmills to grind corn, to pump water, and to run 
sawmills. Today, we use wind to make electricity.
 The energy in wind comes from the sun. When the sun shines, it heats the Earth. Some parts of 
the Earth get hotter than others. An area where land and water meets is a good example. Land usually 
absorbs and releases energy more quickly than water. The air over the land gets hotter than the air 
over the water. The warm air rises and cooler air rushes in to take its place. The moving air is wind.
 As long as the sun shines, there will be winds on the Earth. We will never run out of wind energy. 
It is a renewable energy source. It is also free, since no one can own the sun or the air.
 - windmill (n): cối xay gió - sawmill (n): máy cua - absorb (v): hấp thụ
