请帮我找下下面2句英语句子哪里错了?
1：Someone are talking loudly in the next office
2：Yesterday I bought a book explains how to learn English
答
1、主谓一致规则中有这样一条：someone,anyone,somebody,anyone,something,anything,anybody等不定代词作主语时,谓语动词要用三单.所以are应为is.
2、一句话中不能同时出现两个谓语.（并列谓语不算~）而这句话中bought和explains都是谓语动词,句子结构就不对了.根据句意,explains how to learn English指的是a book,因此应当改为定语从句或非谓语动词结构.可以在explains前加关系代词that或which,变为定语从句.也可以把explains改为explaining,用现在分词作定语.
