语法求助，详解！！！

Question

He often sat in a small bar drinking considerable more than ( ).
A. he was in good health B.his health was good
C.his good health was D.was good for his health

Answer 1

答案为D。than此时为特殊的关系代词引导定语从句，它在从句中一般作主语，也可以作宾语，than前面的主句需要有形容词的比较级形式，且比较级所修饰的名词为本定语从句中的先行词。He often sat in a small bar drinking considerable more (alcohol) than was good for his health. 句中，省略了drinking的宾语alcohol，加上以后，实际上alcohol就是先行词，than是关系代词，同时在定语从句中作主语。类似的例子有：My parents often give me more pocket money than I need. 此句中pocket money为先行词，than为关系代词，同时在定语从句中作宾语。追问

than后面的句子也省略了主语what吧，而且alcohol应该是在considerable和 more 之间吧？

追答

than本身就作后面个句子的主语，所以后句的主语是than，而没有what.

追问

than 可以作主语吗？不好意思

追答

嘿嘿，特殊的关系代词，可以在从句中作主语也可以作宾语。

追问

嗯~谢谢你

Answer 2

D. was good for his health
这是一句比较状语从句，全句为：
He often sat in a small bar drinking considerable more than was good for his health.
其中more than后面其实跟一个 what 引导的状语从句，只是这里 that 给省略了。
意思是：他经常坐在一家小酒吧里喝得已经远超过他的健康所允许。

Answer 3

D.was good for his health
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。

Answer 4

答案才C more than 后面常加sth. 意思为比。。。。多或而不是什么。。。
