英語四級(jí)詞匯考點(diǎn)歸納：減少

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

英語四級(jí)譯文:

身體能量是有限的，而且會(huì)隨著年齡的增長(zhǎng)而減少，而精神的能量則是無限的，它與基因或成長(zhǎng)經(jīng)歷無關(guān)。

四級(jí)詞匯講解:

本句的主干是emotional energy is unlimited and has nothing to do with genes or upbringing。unlike physical energy作整句的方式狀語，其中還帶有一個(gè)which引導(dǎo)的非限定性定語從句，修飾physical energy。

finite意為“有限的”。如:

We should treasure our finite fossil fuel reserves.我們應(yīng)該珍惜有限的礦物燃料儲(chǔ)備。

finite的反義詞為infinite(無限的)。如:

It is difficult to grasp the concept of infinite space.掌握無限的空間概念是很難的。
