1. Don’t you know that lady living next to yours?

要点解析：living next to yours是现在分词短语做后置定语，修饰名词lady。此外，yours在这里指代your house。

2. You want to cozy up to the film star, don’t you.

要点解析：这是一个反义疑问句，结构为陈述部分肯定句+疑问部分否定句，可记为“前肯后否”。 回答时，如果情况属实，用Yes加上反问句的倒装肯定句；如果情况不属实，则用No加上反问句的倒装否定句。例如：
2. You were moved by your students, weren’t you?

情况属实：Yes, I was. 情况不属实：No, I wasn't.
