to influence someone so that they change their opinions
本意是“摇晃、摇摆”，引申为“影响、使动摇”，很多时候可以用来替换influence和impact，但前者影响程度更深。
Don't be swayed by your emotions.
Across much of the West, people are swayed by populist politicians.
作业：
1. People are swayed by ads and buy things they totally don't need.
2.Don't let your parents sway your opinions of your major and career.
