Question

一个太简单英语问题

The Social Security Retirement Program is made up of two trust funds, the larger of which could go penniless by next year.
请问the larger of是什么成分？变成the larger one of which 可不可以？

Answer 1

可以变成the larger one of which
the larger 连上of 一起作定语，修饰which（即：trust funds），较大的那个信托基金

追问

变成the larger one of which
那the larger one 做什么？定语？

追答

the larger 是将形容词性的短语视作名词，不省略完整的应该是the larger one，因此不管是the larger还是the larger one都一样，在定语从句中作主语的定语，定语从句是：
the larger of which could go penniless by next year. 先行词是trust funds（在从句中作主语），将先行词代回从句中，即是 the larger of the trust funds could go penniless by next year.
因此是作主语的定语，修饰主语，说明是怎么样的信托基金，是较大的那个
