问题描述：
Dr.Smith was always ______ the poor and the sick,often providing them with free medical care.
A) reminded of B) absorbed in C) tended by D) concerned about
答
选D 因为concerned about是关心：“斯密斯先生总是关心贫穷和生病的人,经常免费为他们提供药品”
希望还能够帮到你!SMITH 后面有个WAS 为什么仍然要用主动的形式呢？was 是be动词，be concerned about sth是固定词组：“关心”，没有被动语态意思。
