15．Liu Ming jumps highest he isn't the tallest in our class．（ ）| A． | because | B． | though | C． | for | D． | so |
分析 尽管刘明不是我们班里最高的，但他跳得最高．
解答 答案：B；because因为；though虽然；for为了；so于是；对比"Liu Ming jumps highest刘明跳得最高"和"he isn't the tallest in our class他不是我们班里最高的"，可知二者之间是让步关系；though后引导让步状语从句；故选B．
点评 连词在句子中主要起联系上下文的作用，他们之间的区别就是表示逻辑关系的不同，所以在解题时先要理解上下文含义，然后根据上下文逻辑关系选择合适的连词．连词的用法都比较多，语义之间还有交叉，熟记其基本应用规则，了解其区别，注意固定搭配对象，是做好此类题型的关键．
