Passage 21

The last part of this century will be an age of exploration as man has never known.There are eight planets,at least thirty moons,and thousands of asteroids to be explored.Their total area is about 250 times that of the earth.Spaceships will not be able to land on some of them.But that still leaves to be explored an area ten times as great as the continents of the earth.

Exploring space may seem terrifying to some people.No doubt explorers of the past were terrified by the great empty oceans that lay before them.They conquered their fears,crossed the oceans,and built the New World.

Passage 22

All the useful energy at the surface of the earth comes from the activity of the sun.The sun heats and feeds mankind.Each year it provides men with two hundred million tons of grain and nearly ten million tons of wood.

Coal,oil,natural gas,and all other fuels are stored-up energy from the sun.Some was collected by this season’s plants as carbon compounds.Some was stored by plants and trees ages ago.

Even waterpower derives from the sun.Water turned into vapor by the sun falls as rain.It courses down the mountains and is converted to electric power.

Light transmits only the energy that comes from the sun’s outer layers,and much of this energy that is directed toward the earth never arrives.About nine-tenths of it is absorbed by the atmosphere of the earth.In fact,the earth itself gets only one half-billionth of the sun’s entire output of radiant energy.

Passage 24

Before trains,most things went by road.But 200 years ago the roads were very bad,and the horses couldn’t pull the heavy wagons very fast.Sometimes,when the road was wet,they couldn’t pull them at all!When that happened,the driver took flat pieces of wood and put them on the ground under the wheels;then it was easy to pull the wagons,and the horse could do the job very well when the road was flat.When the road was going down a hill,the horse didn’t pull the wagon at all,but when the road was going up a hill it was very difficult to pull the wagon.

On the first railways,the horse pulled the train when the road was flat.There was a wagon at the back of the train to carry the horse when the train was going down a hill.There was an engine with a long rope to pull the train when it was going up a hill.But the engine stayed in the same place all the time;it didn’t move with the train.

The first engines didn’t work very well,and they sometimes didn’t work at all,but they often helped the horses to climb up the hills.

Then Richard Trevithick had an idea:“Let’s put the engine on the train,”he said,And that was the first real train.
