网友回答
(答案→)76. in →from
解析：
77. live used to do sth.表示过去常常做某事，而现在不在做了。
78.这里表示老的意思，不含比较级。
79.表示现在已经不在了，应是现在时态。
80. There be 句型中的谓语动词应与be后面的第一个主语来决定，a park为单数，故谓语动词也用单数。
81. 正确
82. 根据谓语是单数，此句应是：一个体育中心建成，故sports前加不定冠词。
83.指代错误，根据句意是指这个城市，应用its。
84. 此句不应用被动结构，应用主动形式，故将been去掉。
85.根据句意，前、后句是转折，故将besides改为but。
