三、改错
1. but→and　解析：由语境可知，此处不是转折关系，而是顺承关系。
2. but→and　解析：由语境可知上下文之间是顺承关系，不是转折关系，故将but改为and。
3. but→so/and　解析：分析句意可知，前后两个句子可以是因果关系或并列关系，因此将but改为so或and。
4. or→and　解析：句意：那里空气新鲜并且有青山。前后句为并列关系，故将or改为and。
5. 删除so　解析：这是一个简单句，不需要连词。
6. 删除and　解析：本句是主从复合句，从句中已经含有连词Once，所以主句中不需加并列连词。
7. 去掉and　解析：句意：每当我看到那顶草帽，它就使我想起几年前的那次旅游。此处Every time为连词，引导时间状语从句，所以删除连词and。
8. 去掉but或but→yet　解析：连词although不能和but连用，因为这两个词都是连词，由于although置于句子的开头，如果去掉，we需要大写首字母。因此需改动but处。
9. but→and　解析：此处表示一些人的手机铃声听起来吵闹且令人不快。noisy和unpleasant并列，不是转折关系，故将but改为and。
10. 删除but　解析：句中已经有了“In spite of”，故把连词but去掉。
