In fact, they declared that they were【C4】______of what the boxes contained and had acted in good faith in bringing【C5】______into Britain.

【C4】
选项 A、unconscious
B、unaware
C、unfamiliar
D、unknown
答案B
解析 此题属近义辨析题。A项unconscious意为“失去知觉的，无意识的”，常用于be unconscious of sth．／that结构；B项unaware意为“不知道的；没有觉察到的”，常用于be unaware of sth.／that结构；C项unfamiliar意为“不熟练的”，常用于be unfamiliar with sth．或者be unfamiliar to sb．结构；D项unknown意为“未知的”，常用于be unknown to sb．结构。这句话是说，他们四人声称对箱内装的物品不了解，未发觉是毒品，因此应选B项unaware。
