①古希腊哲学家亚里士多德将笑视为“对健康极有价值的身体运动”。②但是，笑很可能对身体健康影响甚微，尽管有些观点与之相反。③笑确实会引起心脏及心血管功能的短期变化，提高心率和耗氧量。④但因为大笑很难维持，所以它不大可能像散步或慢跑那样有显著的成效。
Ancient Greek philosopher Aristotle viewed laughter as a bodily exercise precious to health.
这句话是一个结构非常清晰的**主谓宾（SVO）**句型，同时带有一个较长的后置定语。我们来逐个拆解一下它的句子成分：
1. 主语部分 (Subject)
- Ancient Greek philosopher Aristotle
：整个短语作主语。 - Aristotle
是核心名词（中心语）。 - Ancient Greek philosopher
是前置定语，用来修饰 Aristotle，说明他的身份是“古希腊哲学家”。
2. 谓语部分 (Predicate)
- viewed
：及物动词作谓语，意思是“认为、看待”。
3. 宾语部分 (Object)
- laughter
：名词作宾语，是 viewed 的动作承受者。
4. 宾语补足语 (Object Complement)
- as a bodily exercise
：由 "as + 名词短语" 构成，作宾语补足语。它和前面的 viewed 构成了固定搭配 view A as B（把A看作B），用来补充说明宾语 laughter 的性质。 其中 a bodily 是前置定语，修饰 exercise。
5. 后置定语 (Post-modifier)
- precious to health
：形容词短语作后置定语，修饰前面的名词 exercise。 这里相当于省略了关系代词和be动词的定语从句：(which is) precious to health（对健康宝贵的）。 - to health
是介词短语，作状语修饰形容词 precious。
💡 整句逻辑串联：[古希腊哲学家亚里士多德]（主语） [认为]（谓语） [笑]（宾语） [是一种身体锻炼]（宾补），[（这种锻炼）对健康很宝贵]（后置定语）。
中文参考翻译：古希腊哲学家亚里士多德认为，笑是一种对健康十分宝贵的身体锻炼。

Those forced to exercise their smiling muscles 18 more enthusiastically to funny cartoons than did those whose mouths were contracted in a frown, 19 that expressions may influence emotions rather than just the other way around. 20, the physical act of laughter could improve mood.
尽管悲伤也先于眼泪出现，但有证据表明，情绪可以由肌肉反应引发。在1988年发表的一项实验中，德国维尔茨堡大学的社会心理学家弗里茨·斯特拉克要求志愿者用牙齿咬住一支笔——从而做出一个假笑——或者用嘴唇夹住笔，这会产生一种不悦的（皱眉的）表情。那些被迫活动笑肌的人，对搞笑卡通片的反应比那些嘴角下拉、眉头紧锁的人更加热烈，这表明表情可能影响情绪，而不仅仅是由情绪决定。因此，笑这一生理行为能够改善情绪。
