1. the store is open late。我觉得是开到比较晚，不敢肯定

2 on one's knees是陷入困境

3. I couldn't make heads and tails of it myself.  heads and tails是头和尾，整个句子就是弄不明白的意思

4. the exhibition halls are arranged more like a family tree rather than the walk-through tine that they used to be. walk-through tine 是什么？我也认为应该是time 不是tine
Walk through time 大体上是走马观花的意思.

5。put air in it  往里打气
