介绍:
CBS新闻：一项新的研究显示，人类的嗅觉远比我们想象得要灵敏的多，我们的鼻子可以区别出1万亿种味道。
CBS News reports that the human nose may be far more discerning than thought, with new research suggesting it can sniff out more than 1 trillion separate scents.
Study co-author Andreas Keller, says it has often been said that humans can distinguish only 10,000 different smells.
But this latest finding suggests that humans can sort through more than 1 trillion smells, which is far more than the number of colors and tones that human eyes and ears can pick out.
