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引導的介詞短語表示“方法、手段”。have a (beneficial impact) on...“對......有有益的影響”。in which引導定語從句修飾the ways。
    譯文：通過關注健康的生活方式，“健康”的歷年就能對人們面對日常生活的挑戰(zhàn)的方法產(chǎn)生有利的影響。
