此部分要点有四：1.调整，2.非法人组织，3.合法权益, 4.自愿原则。

1.“调整”。该词常见的译法有adjust, regulate. Regulate是legal  term of art,而adjust属于ordinary English. Regulate准确。

2.“非法人组织”。个人认为unincorporated organizations，non-incorporated    organizations，organizations    without juridical personality皆可。

3.“合法权益”。rights and interests使用的是叠词，表达准确，符合法律英语风格。Legitimate，lawful，legal未见差异。

4.“自愿原则”。Voluntariness形容词形式为voluntary。

        Regulate

        natural person
