题目内容
13.Anyone,once ____ positive for Ebola,the deadly disease,will receive free medical treatment from the government.( )A. | testing | B. | being tested | C. | tested | D. | to test |
分析 任何人一旦被检测出埃博拉呈阳性(一种致命的疾病),就会接受来自政府的免费治疗.
解答 答案是C.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test和句子主语anyone之间是被动关系,所以答案选择C.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,所以排除B;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.
