Part 2
What sports have been removed from the Olympics? Why?
Golf
rugby
polo
power boating
Because these sports became less popular and had to make way for new, more popular sports.
Part 1
What requirements must be met before a sport can be considered by the IOC?
First, a sport must have its own international association. Next, it must be practised by men in at least 75 countries on at least four continents and practised by women in at least 40 countries and on three countries. Besides, a current sport must be dropped.

背景知识回顾
一、化石燃料 煤、石油和天然气都是古代动植物遗骸 经过一 系列复杂变化而成的,它们是人们生活中经常使 用的主要燃料,因此人们常称它们为化石 燃 料,是不可再生 资源。 二、煤、石油燃烧对环境的影响 1、煤的燃烧对空气的影响2、用石油作燃料,直接燃烧的是石油的加工产 品——汽油、煤油、柴油等,它们燃烧时会排放 出 CO 、 氮的氧化物 、含 铅化合物、未燃烧 的 碳氢 化合物和烟尘等,它们都是大气的污 染物。
