cause: applies to any event, circumstance, or condition that brings about or helps bring about a result: an icy road was the ~ of the accident.   （to bring about使发生，to bring something about means to cause it to happen，即与本组基础词cause互释，如the only way they can bring about political change is by putting pressure on the country要使该国进行政治变革，唯一的办法就是向其施压）





determinant: applies to a cause that fixes the nature of what results: heridity may be a ~ of heart disease.  





antecedent: applies to what preceded and may therefore be in some degree responsible for what follows: the ~s of the faimne.   (cede, ceed, cess三个词根来自同一个词根，表示to go走）





reason: applies to a traceable or explainable cause of a known effect: the ~ I was late was that my car would not start.  （effect效果结果是结果的基础词，和cause对应，同组的result和outcome是特殊的effect，参见2017-08-07结果）





occasion: applies to a particular time or situation at which underlying causes become effective: the assassination was the ~ of the war.





cause原因: 用于任何产生某结果的事件情况状态，determinant决定因素: 指决定结果性质的原因(fix使固定，这里译作决定)，antecedent先行事件先行因素: 指之前发生并某种程度上对结果有影响的事件，reason理由原因: 指可以追溯解释的原因，occasion时间情况原因:  一般指时间或情况，在此时间里或情况下原因开始起效。



记忆方法：1）首字母想成OD CAR车旧了<==原因





         2）原因的意思是产生结果的mean something that produces an effect or result.
