这种想法值得真正的科学探究。迄今为止，这只是我个人的假设。但十亿多年以来，人们一直根据味道选择食物，对味觉需求的满足也许是天生的、至关重要的。
【正确答案】：
THAT THOUGHT IS WORTHY OF GENUINE SCIENTIFIC INVESTIGATION. IT IS MERELY A HYPOTHESIS, SO FAR, AND MY OWN. BUT PEOPLE HAVE BEEN EATING ACCORDING TO FLAVOR FOR UPWARDS OF A BILLION YEARS. THE NEED TO SATISFY THE SENSE OF TASTE MAY BE INNATE AND IMPORTANT.  
【题目解析】：考点：is worthy of：值得；genuine：真正的； investigation：调查；hypothesis：假设；so far：到目前为止，迄今为止；according to：根据；satisfy：满足； innate：天生的。句子结构：第二句中的so far作插入语。最后一句中的to satisfy the sense of taste作定语修饰the need。
