sway本意是“摇摆、摇晃”（及物动词），可以闭上双眼想象，用一只手从左到右摇摆，感受一下sway这个词，通常引申为“影响、是动摇”，英英释义“to influence someone so that they change their opinion”，因此很多时候可以用来替换 influence 和 impact，但sway的影响程度更高

③ 《经济学人》中有一篇关于 Facebook 对美国竞选影响的文章，里面正好先后出现了 sway 和 influence。原文第一句过长，在此有删改：
People wonder whether some content and ads shown to each user could be biased and help sway political attitudes. Could Facebook influence the outcome of this presidential election?
