没错吧.
第一句其实是:祈使句(表条件),+ and +主句(表结果).【这句型可单独记忆】
Do A,and you will benefit from bringing your strengths into full play.
只是这里的 Do A 比较复杂:choose what you are good at when you are choosing a career.
第二句主语是any profession.
any profession needs people (who 【have mastered certain skills】 and 【possess certain qualifications】),小括号内为定语从句修饰people,中括号的两部分为并列关系,这里不要求时态一致,表义正确就好.
