the five-second rule
2016/09/20 08:41:37 網誌分類: 生活
Scientists have done many tests over the years on the?five-second rule?and the?three-second rule. Some tests showed it is safe to eat food you have dropped if you pick it up within a few seconds but most scientists have?debunked?this theory. To debunk something means to show it is false. The words “discredit” and “disprove” have similar meanings. Scientists last week released the findings of a new study on the?five-second rule. The findings showed that there is actually no rule. The amount of germs that stick to food you have dropped depends very much on the type of food and where you have dropped it. If you drop food on the floor of a hospital or public toilet, a lot of?bacteria?will stick to it even if you pick it up within one second.
The study showed that more?bacteria?will stick to food with?moisture?(liquid) such as watermelon than to dry foods such as cookies. According to the study, it is OK for healthy people to eat dry foods such as cookies or candies they have dropped on clean floors, such as the floor of their home, if they pick up the food within a few seconds. I think the?five-second rule?is?a load of bunk?(slang expression for nonsense). I would never eat food I have dropped in public places, such as streets. I don’t even eat food I have dropped on the floor of my own home.

你可知道甚麼是五秒定律（five-second rule）？你若知道，你又是否相信？許多西方人都相信五秒定律（five-second rule），但我不認為有許多亞洲人知道。五秒定律（five-second rule）是指當你跌了食物在地上時，只要在五秒內拾起，仍然是可安全食用的。根據這套規則，細菌（bacteria）在五秒內不夠時間沾在食物之上。有些人則相信三秒定律（three-second rule）而非五秒定律（five-second rule），三秒定律（three-second rule）即是你在三秒內拾起食物。
科學家多年來做了許多有關五秒定律（five-second rule）和三秒定律（three-second rule）的測試，有些測試證明若你在幾秒內拾起你所跌的食物，仍是安全的，但大部份的科學家都駁斥（debunked）這套理論。To debunk something意即揭穿它是假的，discredit 和 disprove都有類近的意思。上星期科學家發表一個有關五秒定律（five-second rule）的最新研究成果，結果表示那其實是沒有任何規則的。沾在食物上的細菌有多少，很關乎你所跌的食物是甚麼，和跌在那裏。若你掉食物在醫院或者公廁的地面上，那麼即使你在一秒內拾起，它仍然是滿佈細菌（bacteria）的。
研究表明，濕潤（moisture）的食物如西瓜，會比乾的食物如曲奇，沾上更多的細菌（bacteria）。根據研究，健康的人若進食掉在乾淨地上，例如他們自己家的地上，並在幾秒內拾起的乾曲奇或軟糖，是可以的。我認為五秒定律（five-second rule）是一派胡言（a load of bunk，俚語），我從不吃那些掉在公共地方，例如在街上的食物，甚至不會吃那些掉了在自己家中地上的食物。
