Edward with his family...living in China.A,e

选B
enjoy doing sth.固定搭配,喜欢做某事；
want to do sth.固定搭配,想要走某事；
with his family相当于补充成分,忽略不看,主语仍旧是Edward,谓语动词要用单三形式.
再问： 如果是and his family 而不是with his family 呢
再答： 如果是Edward and his family，那么主语就是复数，谓语动词就要用复数了。
再问： 谓语动词是指哪个
再答： Edward with his family 【enjoys】 living in China. 句中的enjoys就是谓语动词
