Question

He often sat in a small bar drinking considerably more than ________.
答案是was good for his health.请问这个从句省略的主语是什么、先行词是什么,整个句子的结构是怎么划分的,

Answer 1

省略的主语应当是what
全句的结构
1 主语 he
2 谓语 sat in
3 宾语 a small bar
4 伴随状况状语drinking considerably more than （what was good for his health）.
其中 more than （what was good for his health）是现在分词drinking的宾语从句.
因为本句缺少的部分是宾语从句,所以不存在有先行词的问题.
