英語四級閱讀關(guān)鍵句：250. But those captured were anythin

250. But those captured were anything but terrorists, most of them illegal immigrants from Central or South America.

譯文

被逮捕的并非恐怖主義者，其中大多數(shù)是來自中美與南美的非法移民。

點睛

本句的主干是those were anything but terrorists。過去分詞captued為代詞those的后置定語，兩者為被動關(guān)系；most of them illegal immigrants from Central or South America對主語those起到了補充說明的作用，其中them指代的就是those，這句還可以替換為非限制性定語從句：most of whom were illegal immigrants from Central or South America。

anything but的意思是“決不，根本不”，屬于肯定形式表達(dá)否定含義的情況。如：

The bridge is anything but safe. 這橋一點也不安全。
