20180818长难句

【昨日回顾】

Mental health is our birthright. We don't have to learn how to be mentally healthy; it is built into us in the same way that our bodies know how to heal a cut or mend, a broken bone.

心理健康是我们与生俱来的权利。我们不必学习如何保持健康的心理；它与生俱来，正如我们的身体知道如何让伤口痊愈，如何让骨折好转。

【今日长难句】

Mental health can’t be learned, only reawakened. It is like immune system of the body, which under stress or through lack of nutrition or exercise can be weakened, but which never leaves us.

【结构解析】

1. 首句较为简单。二句主干为主系表结构，即：It/ is /like immune system of the body.

2. 两个which 引导but连接的两个并列的定语从句，定语从句主干为which can be weakened, but which never leaves us. “under stress”和“through lack of nutrition or exercise”是由“or”连接的两个条件状语。

【词的处理】

reawaken / ˌri:əˈweikən / vt. 唤起

immune / iˈmju:n / adj. 免疫的

immune system 免疫系统

nutrition / njuˈtriʃn; NAmE nu- / n. 营养

weaken / ˈwi:kən / vt. 使虚弱，削弱

【参考译文】

Mental health can’t be learned, only reawakened. It is like immune system of the body, which under stress or through lack of nutrition or exercise can be weakened, but which never leaves us.

心理健康无法习得，只能被重新唤醒。它就像身体的免疫系统，在压力之下或缺乏营养、锻炼时会被削弱，但却从未离开我们。

【明日长难句】

When we don’t understand the value of mental health and we don’t know how to gain access to it, mental health will remain hidden from us.
