请问单词occasion、situation、condition、state有什么区别?
感激了先,当然要能看懂的

state,condition,situation,status
These nouns denote the mode of being or form of existence of a person or thing.
这些名词都表示人或事物存在的形式或方式.
State andcondition,the most general,are largely interchangeable:
State 和condition 最普通,在多数情况下可以通用：
a state (or condition ) of disrepair; a healthy state (or condition ).
绝望的状态（或 condition ) ；健康状况 （或 condition ).
“Every body continues in its state of rest ...unless it is compelled to change that state by forces impressed upon it” (Isaac Newton).
“每一个物体保持其静止状态…除非有加于其上的力,它才会改变那种状态” （伊萨克·牛顿）.
“The condition of man ...is a condition of war of everyone against everyone” (Thomas Hobbes).
“人类的状态…是人与人对抗的战争状态” （托马斯·霍布斯）.
Situation more narrowly refers to a state or condition at a particular time as determined by a combination of circumstances:
Situation 较狭义地指由环境综合决定的特定时间上的状态或情形：
“Eternal truths will be neither true nor eternal unless they have fresh meaning for every new social situation” (Franklin D.Roosevelt).
“如果永恒真理不能赋予社会状况新的意义,则它既不为真理也不会永恒” （富兰克林·D·罗斯福）.
Status usually applies to a person or thing considered in relation to others of the same class.With reference to persons it implies relative standing;with respect to things it is roughly equivalent tostate or situation :
Status 通常指被认为与同类或同阶层有关的人或物.指人时暗指相对的地位；指物时大致等同于State 或 situation ：
“Mr.Polly's status was that of a guest pure and simple” (H.G.Wells).
“波利先生的身份纯粹是客人” ( H ·G·韦尔斯）.
