________about her son’s future, the mother has been sleeping very badly these months. A．Concerning B．Concerned C．To concern D．Having concerned

Answer 1

B

试题分析：考查非谓语动词。句意：担心她儿子的未来，那位妈妈几个月以来都没有睡好觉。concerning关于；sb be concerned about...关心/担心......，是固定搭配；相当于sb be worried about...。非谓语的逻辑主语是the mother，故用concerned。故选B。
