任务型阅读,以下图1-2 是一个“魔术绳”的表演，另外五张图是该魔术的解密步骤。请参照解密图，将阅读材料A-E 正确排序，完成1-5小题。

A .Now pick up the scissors. Hold the paper carefully and cut through it. Keep the small piece of string between you and the scissors, so you do not cut the string.                            

B .“Magic string” is a popular magic trick. You can do this trick for your friends or family. You just need a piece of paper, a piece of string and some scissors. That’s all.

C .Pick up the paper and fold side A down. Now your friends can see side B, but they can’t see side A. Side A is shorter than B, so it does not cover the string. Push the middle of the string up, and fold C up over A. Now most of the string is inside the paper, but a small piece of the string is outside. You can see it but your friends can’t.

D .Put one hand over the paper, and then pull the string out slowly with your other hand. The string is still in one long piece!

E .First, fold the paper so that it is like the paper in the picture. Side A is shorter than side B, but not much shorter. Side C is much shorter than Side B. Show the long piece of string so that people can look at it. Put this piece of string on the paper.
