题目内容
16.We've talked about snails (蜗牛) and their slow move.But much of the time snails don't move at all.They are in their shells (壳)-sleeping.Hot sun will dry out a snail's body.So at the least sign of hot sun,a snail draws its body into his shell.A snail will die in a heavy rain.So when it rains,a snail does the same thing,too.A snail can sleep for as long as it needs to.It spends all the winter months in its shell,asleep.
In the spring the snail wakes up.Its body,about three inches long,comes out from the shell.When hungry,the snail looks for food.Its eyes,at the end of the top feelers (触角),are very weak.But its sense (感觉) of smell is very strong.It helps the snail to find food and the new greens.
A snail's mouth is no bigger than the point of a pin (大头针).Yet it has 256,000teeth!The teeth are very small,and you can't see them.If you put a snail in a hard paper box,it will eat its way out!And if a snail wears out its teeth,it will grow new ones.

●●●1903-The first flight succeeded.

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.
