考题讲解

题目分析：
本题看起来很长，但其实就考查两个知识点，一个在于not...but...触发的平行现象，另一个是like是介词，不能做连词。

选项分析：

A选项：not后面是动词motivated，因此but后面也需要将内容以动词的形式出现。

B选项：not...but...连接两者平行有误。

C选项：本选项在平行方面没有问题，但是在中间出现了 like they were more recently，由于they were more recently是一个句子，所以它必须由连词引导。like只能做介词，不能充当连词。

D选项：本选项没有but，不能体现出被两种驱动方式的转折关系，因此，本选项是错误的。

E选项：Correct. 本选项在语法和逻辑上均是正确的。
