【问】 A physicist as such shouldn't be considered an authority on ethics. (Crews)

请说明as such的意义和用法。

【答】 在as such结构中，as是介词，作“作为”解，such是代词，作“像这样的人或物”解。assuch的最常用意义是：“以这样的资格或身份”。例如：

1. He is a brilliant scholar and is everywhere recognized as such. (ALD)

他是位才华横溢的学者，而且各地都公认他确实如此。

2. He is a good man and is-known as such to everybody. (McArthur)

他是个好人，大家都知道这一点。

你所问的句子似应译为：“物理学家按其本行是不应当被看作是伦理学权威的。”

as such还可译为“本身”：

1. Money as such will seldom bring happiness.

金钱本身很少带来幸福。

2. He did not oppose the scheme as such.

他并不反对计划本身。

as such用在否定句中，可译为“确切地说”(properly so called)，“严格说来”(in the strictsense of the word) “(并不)真地”：

1. It isn’t a good book as such but it has some interesting pictures. (Chambers)

它并非真是一本好书，不过它有一些有趣的插图。

2. I didn’t have a nervous breakdown as such，it was more a reaction to overwork.(ALD)

我并不是真的患了精神崩溃症，这只不过是工作过度的反应而已。
