英语四级阅读关键句：248. But Hancock says it is also cru

248. But Hancock says it is also crucial whether a conversation is being recorded and could be reread, and whether it occurs in real time.

译文

但汉考克认为，对话是否被记录，可否被重新阅读，以及是否实时发生，也很关键。

点睛

本句的主干是Hancock says。it is also crucial...为says的宾语从句，其中and连接的是两个由whether引导的主语从句。

crucial的意思是“决定性的，关键的”。如：

The police arrived at the crucial moment. 在关键时刻，警察来到了。

occur只能作不及物动词，意为“发生，想到”。如：It occurred to me that I had forgotten my keys at home. 我刚刚想起来我把钥匙忘在家里了。

in real time的意思是“实时”。如：

It can predict weather in real time. 它可以实时预测天气情况。
