The great statue,which was designed by the sculptor Auguste Bartholdi,took ten years to complete.
问题描述：
The great statue,which was designed by the sculptor Auguste Bartholdi,took ten years to complete.
这句话中为什么took前面省略了?took ten years to complete.这句话是什么结构?
什么情况下可以省略主语？
答
1）which.Bartholdi,是整句的插入语.
2） took 是整句的谓语,并没有省略什么!
去掉插入句后,意思是就是：这伟大的雕塑花了10年才完成.中间插入语,是作了Statue的定语,是说了是由Auguste Bartholdi,这人人设计的雕塑.
不明白再问.which....Bartholdi,是定语从句吧？对的，是which引导的定语从句，在此前后加上逗号，就是表示是插入语，如果把逗号去掉，就只是简单的定语从句，用插入语结构是因为让句子结构不臃肿。
