• 1. Is Fresh Air Really Good for You?   We all grew up hearing people tell us to "go out and get some fresh air." _ According to recent studies, the answer is a big YES, if the air quality in your camping area is good.   _ If the air you're breathing is clean - which it would be if you're away from the smog of cities - then the air is flled with life-giving, energizing oxygen. If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles (肌肉) and your brain.   Recently, people have begun studying the connection between the natural world and healing (治愈). _ In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood (情绪). Greenery is good for us. Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see buildings or sky instead. _ It gives us a great feeling of peace.   _ While the sun's rays can age and harm our skin, they also give us beneficial Vitamin D. To make sure you get enough Vitamin D - but still protect your skin - put on sunscreen right as you head outside. It takes sunscreen about fifteen minutes to start working, and that's plenty of time for your skin to absorb a day's worth of Vitamin D.

  • 2.   Much of the work in today's world is accomplished (完成) in teams. Most people believe the best way to build a great team is to gather a group of the most talented individuals. _ Companies spend millions hiring top business people. Is their money well spent?   _ They focused on football, basketball and baseball. The results are mixed. For football and basketball, adding talented players to a team proves a good method, but only up to the point where 70% of the players are top talent; above that level, the team's performance begins to decline. Interestingly, this trend isn't evident in baseball, where additional individual talent keeps improving the team's performance.   To explain this phenomenon, the researchers explored the degree to which a good performance by a team requires its members to coordinate (协调) their actions. _ In baseball, the performance of individual players is less dependent on teammates. They conclude that when task interdependence is high, team performance will suffer when there is too much talent, while individual talent will have positive effects on team performance when task interdependence is lower. If a basketball star is, forexample, trying to gain a high personal point total, he may take a shot himself when it would be better to pass the ball to a teammate, affecting the team's performance. Young children learning to play team sports are often told, "There is no I in TEAM." _   Another possibility is that when there is a lot of talent on a team, some players may make less effort. Just as in a game of tug-of-war (拔河比赛) whenever a person is added, everyone else pulls the rope with less force.   _ An A-team may require a balance - not just A players, but a few generous B players as well.
