Unlike physical energy, which is finite and diminishes with age, emotional energyis unlimited and has nothing to do with genes or upbringing.  英语六级译文:  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。  六级词汇讲解:  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。  英语六级考点归纳:  diminish, decrease, reduce都可以译为“减少”,三者的区别在于:  ※ diminish强调的是程度的降低。如:  1) He likes to diminish the skills of others.他喜欢贬低别人的技能。  2) As he turned the knob, the sound diminished.他一转旋钮,声音就变小了。  ※ decrease强调的是感情变弱或者数量的减少。如:  1) His interest in this subject gradually decreases.他对这门学科的兴趣逐渐减退。  2) They are making further efforts to decrease military spending.他们正在做进一步的努力,来减少军费开支。  ※ reduce强调的是程度的降低、数量的减少或者能力的降低。如:  1) The new government's prime task is to reduce the level of inflation.新政府的首要任务是降低通货膨胀水平。  2) Taking extra vitamins may reduce your liability to colds.多吃一些维生素会降低你患感冒的可能性。
