题目内容
12.Unless _______,he kept silent all the time.( )A. | spoken | B. | being spoken to | C. | spoken to | D. | speaking to |
分析 除非和他说话,不然他会一直默不作声.
解答 答案:C
此处用在连词Unless之后作状语,相当于Unless引导的条件状语从句(Unless he was spoken to),所以这里应使用过去分词;由于speak为不及物动词,故应在它的后面加介词to,表示的是已完成的动作;故排除A;B.现在分词的被动语态:表示正在进行的被动动作,故排除B;故选C.
点评 做本题时,首先需要掌握"连词+过去分词"做状语,相当于一个连词+状语从句的用法;其次应了解过去分词与现在分词的被动语态的意义及用法区别.
