Which way can cure the mental disorder nearly without bad influence?

参考解析：

细节理解题。该题可定位到第六段最后一句“‘Cognitive-behavioral therapy’, which teaches people to bypass unhelpful thoughts, has few negative connotations.”，“认知行为疗法”教导人们绕开无用的想法，几乎没有负面的含义。该句中的few和题干中的nearly相对应，C项正确；Electric-shock treatment可定位到第五段，没有说到有没有副作用的问题，排除A项；Pharmaceuticals with therapy可定位到第六段第一句“Nowadays treatment is much more likely to be associated with pharmaceuticals (though admittedly this can bring its own problems, notably the risk of addiction) and with therapy.”如今，治疗更可能与药物（尽管无可否认，这会带来自身的问题，尤其是上瘾的风险）和治疗有关。从该句可知Pharmaceuticals with therapy是有风险的，排除B项。故选C。
