2017年高考英语短文改错答案|2017年高考英语短文改错技巧：并列连词

短文改错对并列连词的考查主要涉及and， but， or， so等几个表示并列、转折、选择、因果等关系的词语。严格说来，这类错误主要属于行文逻辑的错误。
　　真题单句归纳：
　　(1) We tried to fix it and there was nothing we could do. (and 改为but，因此处语意转折)
　　(2) She was smiling but nodding at me. (but 改为 and，因此处并无转折之意(全国)
　　(3) It looks as if my parents treat me as a visitor and a guest. (and 改为or，a visitor 和 a guest 应是选择关系，意思是“好像我的父母亲把我当作一个来访者或一个客人”)
　　(4) The food was expensive and the service was good. (and 改为but，此处意义发生转折)
　　(5) My grandma was the best cook in the world but could make the mostdelicious dishes.(but 改为and，此处表示并列，而不是转折) (江苏卷)
