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.
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。
※ more and more意为“越来越多的”。如:
The teacher was becoming more and more irritated by the boy's behavior.老师对男孩的行为越来越感到生气。
※ more or less意为“几乎，差不多，大概”。如:
I learnt my lines more or less by heart.我几乎把台词都背了下来。
※ what is more意为“更有甚者，更为重要的是”。如:
You've made a serious mistake, and what's more you knew it!你犯了个严重的错误，但更糟的是:你明知故犯!
