Take any long piece of paper. Now glue the ends of the paper together. You have made a ring.
Take a second long piece of paper. Twist(turn round)the paper once and glue the ends together. Now you have made a Mobius band. For people who study math,this band is special.
This strange band was first made in the 1800s by a German man named August Mobius. Mr Mobius studied math. He wanted to find a way to prove how this band works with math. Believe it or not,this band has only one surface. You can find t his out for yourself.
If you draw a line on the surface of the paper before you twist and glue it,the line is only on one side of the paper. The paper has two surfaces. However,if you draw a line after you make the Mobius band,you can follow the line around all sides of the paper. In other words,the Mobius band must have only one surface.
It is also kind of fun to see what happens when you cut the band. If you cut the Mobius band in half once down the line you dfew,you do not get two Mobius bands. Instead,after you cut the band,it turns into one large twisted ring. Then,if you cut this ring in half along the middle of the band again,you get two connected Mobius bands.

When you read a story in English, do you read it for the story or for the English? This is a 1 that is not so foolish 2 it may seem. For I 3 that many students of English 4 far more attention to the story than to the English. They read and 5 and for a long time 6 remember the story, but do not care to study the 7 of words and 8 in it.
