And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial impact on the ways in which people face the challenges of daily life. (06.12 Passage 2)
主干：the concept...can have a (beneficial impact)
句首by引导的介词短语表示“方法、手段”。have a (beneficial impact) on...“对......有有益的影响”。in which引导定语从句修饰the ways。
译文：通过关注健康的生活方式，“健康”的历年就能对人们面对日常生活的挑战的方法产生有利的影响。
