大学英语A4一、阅读理解1、Take any long piece of paper. Now glue（粘）the ends of the paper together. You have made a ring. Take a second long piece of paper. Twist the paper once and glue the ends together. Now you have made a Mobius band（带子）. For people studying maths, this band is uncommon. This strange band was first made in the 1800s by a German man named August. Mobius. Mr. Mobius studied maths. He wanted to find a way to show how this band works with maths. Understand it or not, this band has only one surface. You can find this 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 very interesting to see what happens when you cut the band. If you cut the Mobius band in half once down the line you drew, 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（相连的）Mobius bands.(1)、What is a Mobius band? A：A long piece of paper. B：A paper ring for people to wear.
