16.I won't give you any help __ you tell me the truth.It's none of my business.( 。
A.unlessB.sinceC.as ifD.even if

分析 即使你告訴我真相,我也不會給你任何幫助,這不是我的事.

解答 答案D.
unless"除非,如果不",在意義上相當(dāng)于if…not,因此在有些場合中unless與if…not可互換使用,引導(dǎo)條件狀語從句.since意思是"自從…以來"時,引導(dǎo)時間狀語從句;意思是"既然"時,引導(dǎo)原因狀語從句.a(chǎn)s if"仿佛,好像",引導(dǎo)方式狀語從句.even if"盡管,即使",引導(dǎo)讓步狀語從句.分析可知前后兩句話之間是邏輯上的"讓步"關(guān)系,再結(jié)合句子所表達(dá)的意思可知答案選D.

點評 本題考查從屬連詞的用法.連詞的用法辨析,要注意分析主從句之間的邏輯關(guān)系,再確定相應(yīng)的連詞,同時注意不同的連詞的語義及用法區(qū)別.
