正确的句子应该是：

1. Any more questions to ask? 

说明：any more 后面可以接复数名词或不可数名词，不能接可数名词的单数形式。

2. China is larger than any other country in Asia.

说明：any other country 其它任何一个国家，any other countries 其它任何一些国家。

3. Excuse me, do you know it's (或 it is) against the law to ride your bike without lights.

说明：it 是形式主语，to ride your bike without lights 是真正主语。
