_____ Jane_____ her brother is going to the movies this weekend. One of them has to stay at home to look after their sick mother.
句意：简或者她哥哥这周末要去看电影，他们中的一个不得不待在家照顾他们生病的母亲。
考查连词辨析。Neither…nor…（两者中）既不……也不……；Either…or…表示两者之一，或者……或者……，要么……要么……；Both…and…两者都；Not only…but also…不仅……而且……。根据句中“One of them has to stay at home to look after their sick mother.”可知，他们中只能有一个人去看电影，所以此处使用either…or…。故选B。
