Testing the five-second rule
You may have seen a friend drop food on the floor, pick it up, and eat it, while declaring, “Five-second rule! ” It's said that food dropped on the floor for five seconds or less is still likely to be clean. .
Students at Britain's Aston University, led by microbiology professor Anthony Hilton, tested the rule and found it to have some scientific basis. The study's results show that food dropped for five seconds is less likely to contain bacteria than if it sits there for longer, according to Hilton.
The students also found that the type of flooring where the dropped food lands has an effect. Bacteria are most likely to transfer from tiled (铺瓷砖的) surfaces to moist food when the food has stood there for more than five seconds.
Therefore, consumers should still be cautious. “However, the findings of this study will bring some light relief to those who have been employing the five-second rule for years, despite a general consensus that it is purely a myth,” professor Hilton said in a statement.
The research team at Aston also surveyed 500 people to find out who employs the five-second rule. Of the people surveyed, 87% said they would eat food dropped on the floor, or have done so in the past. “Our study showed people are also more likely to follow the five-second rule, which our research has shown to be much more than an old wives' tale,” Hilton says.
Still, scientists say you should be careful about eating food dropped on the floor, especially if you have doubts about the cleanliness of the surface.

How to Master Your Public Speaking Voice
Public speaking skills can be a disaster if you don't know how to use your voice. However, a little bit of practice and a confident outlook can help you to be a fantastic public speaker. {#blank#}1{#/blank#}.
Learn the sound of your own voice
Record yourself as often as possible—speaking your thoughts aloud, having conversations with friends, giving a presentation at work, etc. so you can hear what your voice sounds like when you are relaxed, having fun, and in stressful situations. {#blank#}2{#/blank#}.
Master your breathing
The first step in developing a strong public speaking voice is mastering your breathing. {#blank#}3{#/blank#}, which causes their voices to sound high and weak. Develop a habit of breathing deeply at a controlled pace throughout the day so that when it comes to your time to speak, you'll have less trouble doing it.
{#blank#}4{#/blank#}.
It's not just your breathing and vocal cords (声带) that have a physical vocal on your voice. When it comes to public speaking, it is essential that you stand or sit with your back straight. This makes your voice stronger and clearer by allowing you to breathe deeper. It also has the added benefit of making you look more confident.
Adjust your speaking rate
Speaking too slow can cause people to get bored while speaking too fast can be hard to follow. {#blank#}5{#/blank#}. The best speaking rate is in the range of 120-160 words per minute. Practice to control your time.
