as…as连接两个“主语+be+形容词”句子

as…as通常表示“一样…”，连接两个“主语+be+形容词”的句子，底层逻辑还是表示“一样…”，但一般译作“既…又…” 。

例：AIDS is as mystifying to the public as it is frightening.

底层逻辑：对公众来说，mystifying和frightening是同样的程度。

译：艾滋病对公众来说，既令人感到神秘又令人感到惧怕。

再如：

1. His act seemed as unreasonable as it was impolite. 他的行为既不礼貌又不合理。

2. She was as quiet as she was plain. 她的性格温和，相貌平平。
