minus是动词哦，中间的两句话是插入语，真正句子的部分是“It's by considering all these things that you reach the conclusion that on average, free trade benefits us all”。其含义可以理解为“减，得失相抵”
the risk of losing your job one may minus the risk of losing it another有自由贸易时失业的危险减去没有自由贸易时失业的危险
the extra money you make if your industry is shielded from foreign competition minus the extra money you pay for goods and services that are protected没有外来的竞争时公司多赚的利润减避开外来竞争多花的钱
最终得到的结果是：自由贸易在总体上使人人获益
希望对同学有帮助~
