长难句解析
A few years ago, scientists (主语) discovered (谓语) [the liver releases a hormone to suppress consumption of sweet-tasting food] (宾语从句) [once a person has consumed high volumes of sugar] (条件状语从句).
这一句话有点长,咱们找主干,简单主谓宾结构,scientists discovered...科学家们发现了某事,接下来省略了 that 的宾语从句,the liver releases a hormone to suppress consumption of sweet-tasting food,从句的结构也是简单主谓宾,同样先找主干,主语 the liver 肝脏,接下来 to 引导目的状语, 主干句意思就明确了,科学家们发现,肝脏会释放一种激素来抑制对甜食的消耗。什么情况下会这样呢?接下来看枝叶部分,句末 Once 引导条件状语从句,还是简单主谓宾,a person 一个人,这里是一种泛指,has consumed high volumes of sugar,这里是说大量的糖分。所以条件出来了,一旦摄入大量糖分,最后再看句首,研究的时间是 a few years ago 几年前,结合主句,整句话的意思是几年前,科学家发现,一旦人摄入大量的糖分,肝脏就会释放一种激素来抑制对甜味食物的消耗。
