题目内容
9.All living things on the earth need other living things to live.Nothing lives alone.Most animals must live in a group,and even a plant grows close together with others of the same kind.Sometimes one living thing kills another,one eats and the other is eaten.Each kind of life eats another kind of life in order to live,and together they form a food chain(食物链).Some food chains are simple,while others are not.But all food chains begin with the sun,and all food chains become broken up if one of the links disappears.All life needs sunlight to live on.But only plants can use sunlight directly.Plants are"factories".They make food from sunlight,water and things in the soil and air.
Plants feed all other living things.Animals can only use the sun's energy after it has been changed into food by plants.Some animals feed directly on plants,others eat smaller animals.Meat-eating animals are only eating plants indirectly.
What about human beings?We are members of many food chains.We eat wheat,rice,vegetables,fruits and so on.We also eat meat and drink milk.But men often break up the food chains.They kill wild animals.They also make rivers,lakes and seas dirty.When these rivers,lakes and seas are polluted,the fish in them cannot be eaten.If men eat the fish,they will get strange diseases.
Each form of life is linked to all others.Breaking the links puts all life in danger.

●●●1903-The first flight succeeded.
In 1900,Wilbur Wright said flight was possible for man.After much work he and his brother Orville Wright made this dream come true.
On December 17,1903,the brothers made the first successful airplane flight on a windy beach at Kitty Hawk,North Carolina.The brothers'plane flew 120feet.Although the flight lasted only 12seconds,it moved the course of history in a new direction.
●●●1935-Nylon was invented.
In 1928,a new chemical lab was opened to make a kind of man-made materials.Wallace Carothers took part in the team when he was 32years old.
In 1934,he made fibers (纤维),but the fibers were quite weak.He didn't give up.After many experiments,he produced the long and strong fibers in 1935.They named the fibers"nylon".Carothers was very satisfied with his work.
Nylon hit the markets in 1939,and quickly became a replacement of silk.But it was a pity that he didn't see the wide use of his invention.He died in April,1937.
●●●1968-The computer mouse was first shown in public.
As a graduate student,Douglas Engelbart began to imagine ways in which all sorts of information could be on screens.
In 1964,Douglas Engelbart made the first computer mouse.The computer mouse had a wooden shell with two metal wheels.
In 1968,the first computer mouse appeared in public.It was named"mouse"because a tail came out at the end.In later years,the computer mouse became more and more important.
Douglas Engelbart changed the way that computers worked.
Now computer mice are becoming increasingly useful.And there are many different shapes of computer mice in the world.
