270. The more often the memory is recalled afterwards, the more likely it is that permanent finks develop between the nerve cells--and the pattern will be shored as a long term memory.

英语四级译文:
事后回忆进行得越频繁，就越有可能在神经细胞之间建立永久的关联—而这种模式也将作为长期记忆被存储。

四级词汇讲解:
本句的主干是the more often memory is recalled, the more likely it is that。afterwards为recalled的状语;that引导的是表语从句，该从句实际上是由破折号和and共同连接的并列句;as a long-term memory为stored的方式状语:afterwards的意思是“后来，以后”。

the more…the more…的意思是“越……越……”。如:
The more you learn, the more you know.学得越多，知道得也越多。
