they really were.后面的表語就是as前面說的一句話所表明的狀態(tài),因此這里需要as連接,這種句式的目的是強(qiáng)調(diào)were后面的這個事實情況,即as前面的的一句話所表明的觀點；
如：they were fast as they really were.意思即為：他們確實很快.如果不要as后面的一段話,they were fast意思就是,他們很快.缺少強(qiáng)調(diào)的語氣.而這里,as they really were后面的表語既是前面這句話“they were fast”所表明的狀態(tài),突出強(qiáng)調(diào)語氣.
