Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time, according to the findings of research carried out at Aston University’s School of Life and Health Sciences.
食物拿起几秒钟后被删除不太可能含有细菌,而不是离开的时间更长,根据研究的结果在阿斯顿大学生活和健康科学。

The findings suggest there may be some scientific basis to the “5 second rule” – the belief about it being fine to eat food that has only had contact with the floor for five seconds or less.
调查结果显示可能会有一些科学依据“5秒规则”——对它的信念可以吃食物,只有与地板接触了5秒或更少。

这段就是说掉地板上小于5分钟食物在捡起来不太可能含有细菌比它长时间留在地板上。根据t Aston University’s School of Life and Health Sciences研究的调查。这份调查也表明了有关于去吃地板上小于5分钟的食物还是ok的“5 second rule 或许有一定科学成分。我觉得about是介词，后面就只能是动名词了，而it在动名词之前倒有个语法动名词的复合结构，这样it 就是动名词逻辑主语，而it 又是一个形式主语，真正主语是后面不定式to 。。。。也就是换个形象点表达就是{to eat food that has only had contact with the floor for five seconds or less }being fine

it 是形式宾语，being fine to eat food 是about d的真正宾语。that 往后是修饰food 的定语从句
