Step 1：通读全文，掌握主旨大意。
本文为说明文，题材为介绍说明类。介绍the One World Futbol的一些情况。
Step 2：逐题解答，确定答案。
1．Because。考查连词。因为运动场地地面不平且多岩石，所以成百上千万的球玩不到一天就变瘪了。
2．within。考查介词。真正的球在24小时之内就会瘪掉。within 24 hours“在24小时之内”。
3．he。考查代词。上文提到了Tim Jahnigen，一位加利福尼亚的商人，所以用he来指代Tim Jahnigen。
4．a。考查冠词。a special material“一种特殊的材料”。
5．most。考查副词。most important意为“最重要的”。
6．and。考查连词。此处表示并列关系，所以用and。the One World Futbol不需要充气也不容易坏掉。
7．it。考查代词。it指代the One World Futbol。
8．than。考查比较连词。根据本句中more的暗示，填than。
Step 3：代入验证。
需考虑语法结构正确且语义符合逻辑，语法结合语义才能确保万无一失。
