3 完形填空。 It was Tom"s first visit to England, and he was looking forward to his first journey on London"s Underground Railway. And against his friends" 1 , he was determined to travel 2 . He entered the station shortly after five o"clock in the afternoon. This is a 3 time to travel in London, 4 crowds of people go home from work at this hour. He 5 to join a long line of people waiting for tickets. When at last his 6 came, he had some difficulty in making himself understood by the ticket seller. 7 , he got the right ticket in the end and by asking people the 8 , he also found the right platform. It was 9 with people. He did not 10 to get on the first train, but he was able to move nearer to the platform so as to be in a better 11 to get on the next one. When this train came in, Tom was 12 forward onto the train by the 13 of people from behind. The doors closed and the train moved off. He was unable to see the 14 of the stations where the train 15 , but he knew that the station he wanted was the sixth 16 along the line. When the train reached the sixth station, Tom got off, feeling 17 that his journey had been so easy. But he suddenly realized that he had come to a station he had never 18 . He explained his 19 to a man who was standing on the platform. With a 20 on his face, he told Tom that he had caught a train going in the opposite direction. ( )1. A. thought ( )2. A. alone ( )3.

7 对于弱酸，在一定温度下达到电离平衡时，各微粒的浓度存在一种定量的关系。如25℃时有HA H ++A -，则电离平衡常数，K只与温度有关，c为各微粒的平衡浓度。下表是25℃时几种常见弱酸的电离平衡常数。回答下列各题： (1)K只与温度有关，当温度升高时，K值____（填“增大”、“减小”或“不变”）。 (2)在温度相同时，各弱酸的K值不同，那么K值的大小与酸性的相对强弱的关系是___ (3)若把CH 3COOH、H 2CO 3、HCO 3 -、H 2S、HS -、H 3PO 4、H 2PO 4 -、HPO 4 2-都看作是酸，其中酸性最强的是 ____，最弱的是____。 (4)多元弱酸是分步电离的，每一步都有相应的电离平衡常数，对于同一种多元弱酸的K 1、K 2、K 3之间存在着数量上的规律，此规律是____，产生此规律的原因是________。 (5)电离平衡常数是用实验的方法测定出来的，现已经测得25℃时cmol/L的CH 3COOH的电离度为a（当弱电解质在溶液里达到电离平衡时，溶液中已电离的电解质分子占原来总分子数的百分数叫做该电解质的电离度）。试表示该温度下醋酸的电离平衡常数K=____。
