Hospital statistics regarding people who go to the emergency room after roller-skating accidents indicate
the need for more protective equipment. Within that group of people, 75 percent of those who had accidents in
streets or parking lots had not been wearing any protective clothing (helmets, knee pads, etc.) or any
light-reflecting material (clip-on lights, glow-in-the-dark wrist pads, etc.). Clearly, the statistics indicate that by
investing in high-quality protective gear and reflective equipment, roller skaters will greatly reduce their risk of
being severely injured in an accident.
以下是lz对这道题目的理解，但是不确定，还请各位指点：
对去emergency room的伤员调查，发现75%没有戴保护工》》》戴这些工具可以防止severely injured
Assumption1:去emergency的都是severely injured
========2: 没戴工具导致severely injured
========3: 戴了这些工具就能很好的防止 severely injured
以上是我对这道题目的分析，重点放在了severely上，不确定是不是这样。

1.基本正确
2.个人觉得，没有什么重点，如果要说有重点的话，那可以有好多重点
3.还有一个地方需要注意：“75 percent of those who had accidents in streets or parking lots had not been wearing any protective clothing”
