Question

As time went on he began to wonder if it was realistic for him to expect to find New Cheese.

请问这句的语法要怎么解析呢？

Answer 1

As time went on 时间状语，he 主语began to wonder 谓语if it was…宾语

Answer 2

As time went on : 伴随状语
he : 主语
began to wonder: 谓语
if 之后： 宾语（宾语从句）

Answer 3

主从复合句。As... on 为时间状语从句，从句中 time是主语，went on是谓语。

主句 he began... wonder if... ，其中he为主语，began是谓语，不定式短语 to wonder... 是宾语。而且该宾语中的wonder后面又是一个if引导的宾语从句。该宾语从句中，it是形式主语，was realistic为系表结构，真正主语是后面的不定式to expect... Cheese
