make a decision 作决定,做出决定.没有指定结果,这个决定有待给出.
reach a decision下结论；决定下来；做出决定.例如：
The board reach a decision about closing the factory.老板作出关闭工厂的决定.
这应该是对应结果的.
take a decision做出决定.经过商讨的,经过判决的.
I know they talk about me,and take a decision.I'm a professional and I do it.I don't have a lot of chance to decide.
