不行 你要那样的话就直接The girl I spoke to is my cousin.因为第一句中主是The girl is my cousin.定语从句起修饰作用修饰the girl,意思是我和她说话的那个女孩,我和她说话的I spoke to whom, whom 指代the girl,如果你那样改的话,句子就变成有两个宾语一般的了,I spoke to whom 已经是完整的有whom 作宾语的句子,前面的The girl 和后面的就接不上了.直接去了whom 的话就成为隐藏了that 的定语从句,The girl that I spoke to is my cousin. that 作I spoke to 后面差着的宾语,这就组成完整的宾语从句了.
