【題目】【原創(chuàng)】A man does not know the difficulty of anything_________ he does it personally.

A. although B. if C. because D. unless

【答案】D

【解析】

試題分析：考查連詞。unless本身具有否定意義：if...not，引導(dǎo)的是否定的條件句，這種否定的條件句從反面來強(qiáng)調(diào)的語氣，一些語法學(xué)家稱它為“反面的惟一條件句”，如： One cannot master a foreign language well unless he studies it hard．
