部队专升本大学英语：四级词汇解析：减少

　　Unlike physical energy, which is finite and diminishes with age, emotional energyis unlimited and has nothing to do with genes or upbringing.

　　英语四级译文:

　　身体能量是有限的，而且会随着年龄的增长而减少，而精神的能量则是无限的，它与基因或成长经历无关。

　　四级词汇讲解:

　　本句的主干是emotional energy is unlimited and has nothing to do with genes or upbringing。unlike physical energy作整句的方式状语，其中还带有一个which引导的非限定性定语从句，修饰physicalenergy。

　　finite意为“有限的”。如:

　　We should treasure our finite fossil fuel reserves.我们应该珍惜有限的矿物燃料储备。

　　finite的反义词为infinite(无限的)。如:

　　It is difficult to grasp the concept of infinite space.掌握无限的空间概念是很难的。
