| mark | 标志： Our first studies sought to determine whether the increase in serotonin {observed in rats［given a large injection (of the amino acid tryptophan)］} might also occur /after rats ate meals (that change tryptophan levels in the blood)/. |
| cn | 译文： 我们最初的研究 试图 去确定 是否 {在［被给予了大量（tryptophan氨基酸的）注射的］老鼠身上所观察到的}serotonin的增加 也会发生 /在那些老鼠 吃了 （能够改变血液中的tryptophan的含量的）食物 之后/。 |
| explain | 解释： 由whether所引导的从句的结构很复杂。主语the increase in serotonin 的修饰语就是一大堆，远远地隔开了谓语might also occur ；after引导的从句的结构也不简单，再加上句子中出现了大量的专有名词，使得本句的意思更难读懂。句子的意思其实就是：我们要研究这么一个问题，那就是已知老鼠注射tryptophan后serotonin增加，求解吃了使tryptophan增加的食物后，serotonin是否增加？ |
