          Twentieth Century Inventions
    ●●●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 120 feet. Although the flight lasted only
    12 seconds, 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 32 years 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 computermouse. 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.

         现在，许多中学生沉迷于玩电脑游戏，荒废了学业。有的家长整天忙着谋生对此了解甚少，并且缺乏跟学校老师沟通。为了了解学生中玩电脑游戏的情况，某学校家长委员会组织了专项调查。下文是一位学生的调查报告，请仔细阅读后完成信息卡中的各项内容。

        Now computer games are very popular among middle school students. Half of male students in our class like playing computer games very much .Though our teachers and their parents tell them not to play games any more again and again, they play the computer games daily and they don't go to school. They spend a lot of time playing computer games each time, so they often ask their parents for money or borrow money from their classmates. Some students even use mobile phones to play the games in class. They don’t listen to the teacher carefully and usually forget to do their homework. I think it’s really bad for their lessons.

        Playing computer games wastes money and it is also bad for the students’ health and study. So I hope those who have got the habit of playing computer games could give it up as soon as possible.
