听力原文

271. Decisions are made as to which information should remain in long-term memory.

译文

关于哪些信息应该留存于长期记忆之中的决定已经作出。

点睛

本句的主干是Decisions are made。as to...为句子的状语,其中which引导的是介词to的宾语从句。

make a decision的意思是“作出决定”。如:

I'm really bad at making decisions. 我的确不善于决策。

as to的意思是“至于……,提到……”,也可替换为as regards。如:

There are no special rules as to/regards what clothes you should wear. 至于应该穿什么衣服,并没有硬性规定。

考点归纳

有关as的常见搭配还有:

so as to do sth.意为“为了做某事”。如:

The thief ran off so as not to be caught. 为了不被抓住,那名窃贼跑开了。

as for意为“至于,关于”。如:

You can stay; as for him, he can get out of my sight. 你可以留下来,至于他,他可以从我眼前消失了。

as if/though意为“似乎,仿佛,好像”。如:

It sounds as if he's been really ill. 听起来他好像真的病了。
