专题08 并列句和状语从句—备战2023年高考英语考试易错题【导入】并列连词和状语从句解题思路：1. 句型判断法：细心审题，对号入座2. 逻辑判断法：准确理解句意，确定适当连词技巧1 连词用法要熟记1.（2017·北京）—Peter, please send us postcards we’ll know where you have visited.—No problem.【解析】——Peter，请给我们寄一些明信片，这样我们就能知道你去过哪里。
——没有问题。
根据语境可知，让Peter寄明信片的目的是了解Peter去过哪里，此处表示目的，所以用so连接并列句。
注意：不能误填for，如果后半句表示原因可用for，且之前常有逗号隔开。
【答案】so1．and用法示例意为“和，并且”，当连接三个或三个以上并列的成分时，一般在最后两者之间加and，其余用逗号分开Solid, liquid and gas are the three states of matter.固态、液态和气态是物质的三种状态。
“go (come, stop等)＋and＋动词原形”中，“and ＋动词原形”相当于“in order to＋动词原形”I'll go and bring back your boots.＝I'll go in order to bring back your boots.我去把你的靴子拿回来。
“动词＋and＋动词”，前后为同一动词，表示动作长时间地“继续”或“重复”We waited and waited.我们等啊等。
2．or3．表示对比、转折关系的并列连词有but, yet, whereas, while 等。
►He likes pop music, while I am fond of folk music. 他喜欢流行音乐，而我喜欢民间音乐。
►Some of the studies show positive results, whereas others not. 有一些研究结果令人满意，然而其他的则不然。
