如果你需要做演讲或报 告，记得要把你要讲内容的结构和要点对听众讲清楚。不要害怕解释和总结你的主要论点以便于让观众听明白。为了让听众听听得开心，可以在合适的时候穿插幽默 或者用佚事或对比把自己的观点讲清楚。太抽象和理论性的东西如果听久的话可能会让听众觉得单调无聊。大家选了主题后，我们在这个问题上可以进一步讨论。
Passage two
According to the latest report issued by the Department of Health, there are now 13 states, where more than a quarter of the adult population is overweight or obese. Nevada is the only state that saw a decrease in the percentage of the obese adult compared to last year’s report. Overall, adult obesity rose from 15% in 1985 to 32% in 2007. Taken together, individuals who are either overweight or obese comprise 64% of the US adult population. Obesity among children is increasing at an even more alarming pace, having more than tripled in the past two decades.
