题目内容
15．Once _________，this dictionary will be very popular．（ ）| A． | printed | B． | printing | C． | to print | D． | is printed |
分析 一旦出版，这本词典将会非常畅销!
解答 答案是A．本题考查"连词+分词"的结构．"连词+分词"的结构在句中往往做状语，属于分词做状语；分词做状语时分词的选择是看分词和句子主语之间的关系：分词和句子主语之间是主谓关系（主动关系），用现在分词；分词和句子主语之间是动宾关系（被动关系），用过去分词；本题中连词once后的print和句子主语the dictionary之间是被动关系，所以答案选择A．注意：1）"连词+分词"的结构中分词前不能有任何形式的be动词；2）注意区别，"疑问词+to do"在句中起着名词作用，做主语、宾语或表语，而"连词+分词"在句中充当状语．
点评 首先判断选项中的动词在句中是以谓语还是非谓语形式出现，然后根据选项在句中的功能结合非谓语的基本用法做出合理的判断．要关注常见非谓语动词的搭配．
