B. As long as

C. If only

D. As soon as

Answer 1

【答案】A

【解析】句意:虽然警察们认为他最有可能是罪犯，但因为没有确凿的证据，他们不能逮捕他。本句结构稍微复杂，可改为：Although the police thought he was the most likely one, they could not arrest him, since they had no exact proof about it. 这样可以看出，这是一个复合句，although引导让步状语从句，其余部分为主句，而这个主句又含since they had no exact proof about it. 这一原因状语从句。
