四、阅读理解
People use sailboats mostly for pleasure, but ancient seafaring people depended
on the wind in their sails to carry them all over the world.
Hot air is lighter than cold air. If you put hot air in a balloon, it rises—and
that's how hot-air balloonists float high in the sky. Birds like eagles and hawks fly
high above the ground, too. They spread their great wings to catch warm air currents
and rise in lazy circles above us. Airplanes called gliders are lifted high in the air in
much the same way.
The seaside is a perfect place for flying kites, because the wind almost never
stops blowing. The sand on the beach warms up faster than the ocean does. As the
warm air over the land rises, cool winds blow in from the sea. The beach is a good
place to try hang-gliding(悬挂式滑翔运动), too—which is about as close to being a
human kite as you can get!
Everyone has seen trees waving in the wind. But the wind isn't just spreading
leaves for you to collect as it passes through. It's also helping the trees—and bushes
and grasses and flowers—spread their seeds. Wind carries all kinds of seeds to new
places, where they can take root and grow. Maple seeds, and dandelions, are just a
few of the plants that rely on the wind to help them spread their seeds.
All around us the wind is at work.
It brings changes in the weather. It carries birds, airplanes, boats and seeds to all
over the world. And sometimes, the wind just helps people have fun! With the wind in
your sail, you can go almost anywhere—on water, on ice, on land, and in the air.
The wind touches us all every day of our lives. Everywhere you look, things are
blowing in the wind!
