- status 人在政治、社会、经济、法律上的地位或者身份。也可用于指政治等事态的状况。
status 和其他三个词的差别最大。虽然名词 status也可以描述个人在群体和环境中的位置，但它主要社会中的地位、身份。比如，marital status 婚姻状况。
Examples:
In some societies, lawyers, doctors and professors have a high social status.
Luxury yachts are popular status symbols among the rich and powerful.
- condition 一般强调产生影响的原因或者环境，复数形式指笼统的情况。
第一个用法和 state 相似，只不过在形容人的时候，condition 强调身体状态，而 state 则更重于表示心理上的、精神上的状态。需要注意的是，在这里，condition 常作单数形式。
Examples:
This painting has been preserved with care. It’s in excellent condition.
My grandpa is recovering from an operation. He is in no condition to travel.
- state 人或者物在特定时间的状态，与环境、外表、心灵以及健康相关。或在某一阶段的状态或形式。比如，常用搭配有 state of mind 心态、心情。
Examples:
The news left us all in a state of shock.
The prop manager’s job is to acquire or build props, and keep them in a good state of repair.
He hasn’t been eating properly for a month – I’m worried about the state of his health.
- situation 明确具体的环境情况或处境。
situation 的意思是 特定时间、特定地点的具体情况。举个例子，情景喜剧的英文说法就是 situation comedies，简称 sitcoms 。
Examples:
Don’t put me in a difficult situation!
I don’t know if I would do the same. It all depends on the situation.
- circumstance 周围的情况或某事发生时的情况。
