来自CNN:
When you are out under the night sky in the dark next your family theres nothing like it feel close to each other
and to really connect on a different level than you were during the day.
当你在黑暗的夜空下的时候，，一家人，没有什么能像这样让你们感觉彼此很亲密，不同于白天，真正地进行一个交流。
1）句中出现了than you were during the day. 但是前面没有对应的比较级，请问，这是than比较分句吗？
2) 如果是比较分句，为什么只有than出现，而前面没有比较级呢？主句中的比较项又是什么？
3）比较分句than you were during the day. 如何补全？
4）我一直有这样的疑问：凡是含than的句子，都是比较分句吗？
