Question

 There have been many great inventions 1        change the way we live. The first great 2        was one that is still very important today―the wheel. This made it easy for man 3        heavy things and to travel long distances. For 4      years after that,there were 5        inventions that had as much effect as the wheel. Then in the early 1800s the world started to change 6        There was little unknown land left in the world. People did not have to explore much any more. In the second half of the 19 th cen?tury many great inventions were made. 7      them were the camera,the electric light bulb and the ra?dio. These have all become a big part of our life today.

  The first part of 8        century saw more great inventions. The helicopter was in 1909. Movies 9        sound were in 1926. The computer was in 1928. And jet planes were in 1930. This was also a time when a new 10        was first made. Nylon came out in 1935. It changed the kind of clothes people wear. Of course new inventions continued to be made. Man began looking 11        ways to go into space. Russia made the first step. Then the United States took 12        Since then other countries* including China and Japan, 13        their steps into space. In 1969 man took his biggest step away from earth.14      first walked on the moon. This was certainly just a beginning. New inventions will someday allow us 15        things we have never yet dreamed of.
