3. When my aunt was buried, Clare turned up at the service, …在我姑母下葬时，克莱尔突然出现在葬礼上，------

9. “I’m allowed to change the colour of my hair,” she said angrily.“我可以改变我的头发的颜色，”她愤怒地说。

11. The lawyer was brief and to the point.
律师的答复简明扼要。

该句是个主从复合句，其主句为She instructed in her will,其后接一个that引导的宾语从句。这里that不可以省，而在宾语从句中又包括了一个由if引导的条件从句。在宾语从句中又有一个过去分词called短语作定语。
注意在句中宾语从句含有一个由if引导的虚拟语气的结构。从句中用了were to do结构表示对将来情况的推测或假设。例如：
