如图，在一个密闭的玻璃瓶的塞子上插入一根两端开口且足够长的细玻璃管，瓶内有一定量的水和空气．由于内外压强差，细玻璃管内水面a将与瓶内水面有一定的高度差．已知地面附近高度每升高12m，大气压降低1mmHg；水银的密度为13.6×10³kg/m³．

将玻璃瓶放置在地面上，记录管内水面a的位置，再将玻璃瓶放到离地8m的三楼平台上，则玻璃管内水面a将____（选填“上升”、“不动”或“下降”）____ mm；（设温度保持不变；不计水面升降引起的瓶内空气体积的变化）；用此装置可用来测量高度的变化：先将装置放在温度为27℃、大气压为750mmHg的A处，测得水柱的高度h=204mm．然后将装置缓慢地移到另一高度的B处，待稳定后发现水柱升高了40.8mm，已知B处比A处的温度高1℃，则AB间高度差为____ m．该测量仪器选择瓶内装水而不装水银的主要原因是____．

    On February 9th, 2013, Sarah Darling was walking along the street when she met a homeless man named Billy Ray Harris. She reached into her change purse, emptied out all the coins she had and gave them to the homeless man. Neither of them realized that this small generous act would change their lives.

    Sarah didn't realize that she had given Billy not only all her change but also her diamond ring that she had put in her change purse earlier until the following morning. She and her husband, Bill Krejci, rushed to see if they could find Billy. The homeless man was not only in the same place, he also immediately returned the ring. The grateful couple paid him back for his honesty by emptying out their pockets of all the money they had.

    Bill Krejci, a web designer, felt that he needed to do something more for this amazingly honest man. So on February 18th, he set up a special page to raise money for him. In just four days, Billy received over $85,000 and there seems to be no end yet.

    That is not enough. Billy is living with a person who is generous instead of living in the streets. And that's not all—thanks to the news report, he got together again with his older brother, Edwin Harris, who he had been unable to find for 27 years.

    All the good luck is just because Billy did the right thing—returning something that did not belong to him.
