Apple hopes that the flashynew features of the iPhone 7, which itis expected to introduce in September, will convince customers to abandon older models.
请问:句中的 it 是否多余的?
句中的 it 不是多余的。which it is expected to introduce in September 是定语从句,修饰先行词the iPhone 7,同时 which 在定语从句用作动词 introduce 的宾语;定语从句中的 it 为定语从句的主语。
