请问一下。Many new buildings had expanded around it. However, it was still part of a royal palace and prison combined.中part什么用法呢?为什么它不加冠词而且又不是复数形式呢?希望老师帮忙,谢谢了!
The latest revolution isn"t simply a matter of gentlemen reading other gentlemen"s e-mail.老师好,这里的of gentlemen reading other gentlemen"s e-mail.是不是独立主格结构呀,如果是的话,独立主格结构前面可以加介词是吗?
