"戶外慢跑可能會讓你變笨"

慢跑可以讓人身體健康強壯，但是運動時所吸入的污染空氣卻有可能讓頭腦變笨。比利時研究學者發現，喜歡在城市街道慢跑的人呈現出心智衰退的徵兆，例如注意力減退。他們的大腦發炎指數也較高，這可能會造成未來心智健康問題。專家建議，慢跑者應該避免在交通尖峰時段於主要道路上慢跑。下雨天和颳風天最適合慢跑，因為污染物都被洗盡或吹走了。

對話範例：

(戶外慢跑) 瑪莎是恩尼的母親。恩尼試著說服母親在家買台跑步機，但瑪莎對這主意沒興趣。一起來聽聽他們的對話。

恩尼：媽，買台跑步機妳一定不會後悔。這是最新型號，有三年保固。

瑪莎：但它也非常昂貴。為何不出門去跑就好？呼吸一些新鮮空氣。

恩尼：哪來的新鮮空氣？我們住在市中心，吸進來的除了煙之外還是煙。

瑪莎：你可以到公園裡和朋友一起運動。

恩尼：但我還是會暴露在空氣污染之中。那些煙會影響我的大腦，讓我變笨。你可不會希望兒子變笨，是吧？

瑪莎：喔不，你別想讓我因良心不安而買給你跑步機。

恩尼：我保證每天都會用它跑步。這會是你給我最好的禮物，而且也很健康喔！

瑪莎：等你開始用房裡的啞鈴後我們再討論。你去年拜託我買的，到現在一次都沒用過！

(Health) Jogging Outside Can Make You Stupid

Jogging can make a persons body healthy and strong but the polluted air people breathe in while they exercise can make them more stupid. Belgian researchers found out that joggers who like to run on city streets showed signs of mental decline such as decreased attention spans. They also had higher levels of inflammation in their brains that can cause future mental health problems. Experts suggest that joggers should avoid exercising on main roads during traffic rush hours. Rainy and windy days are perfect for jogging because the pollution will have just been washed or blown away.

Dialogue Example:

(Jogging Outside) Martha is Ernests mother. Ernest is trying to convince his mother to buy a treadmill for their house but Martha is not excited about the idea. Lets listen to their conversation.

Ernest: Mom, you wont regret buying this treadmill. Its the newest model and it comes with a 3 year warranty.

Martha: Its also very expensive. Why not go out and run? Breathe in some fresh air.

Ernest: What fresh air? We live in the middle of the city; all we breathe in is smoke and even more smoke.

Martha: You can go to the park and exercise there with your friends.

Ernest: I would still be exposed to air pollution. The smoke will affect my brain and make me stupid. You dont want that to happen to your son, right

Martha: Oh no, you are not going to guilt me into buying the treadmill for you.

Ernest: I promise Ill run on it everyday. It will be the best gift you can give me and its healthy, too!

Martha: Well talk about it again after you use the dumbbells that are in your room. You asked me to buy those for you last year and you havent even used them once!
