______ about the safety of the people in the earthquake-stricken Lushan county in Sichuan Province, Premier Li has flew there to direct the rescue mission.
A.Concerning
B.Concerned
C.To be concerned
D.Concern
答案:B
题目分析:句意:由于担心四川芦山县地震灾区人民的安全,李 * * 已经飞往那里指挥营救任务。动词不定式表示目的或将来,不符合语境。concern是动词,故排除。这里sb be concerned about关心,担心;这是非谓语动词,故用B。
点评:本题难度适中。主要考查的是非谓语的一些最基本的用法。但是,题目的设置注重了情景化和结构复杂化,加大了考生对题干句的理解难度。
即学即练:__________ and short of breath, Andy and Ruby were the first to reach the top of Mount Tai.
A. To be tired B. Tired
C. Tiring D. Being tired
解析:B。考查动词的非谓语形式。句意为:Andy和Ruby首先登上泰山山顶,疲惫不堪,气喘吁吁的。据句子结构分析,空里填的词应与short of breath并列作结果状语,主语是人,因此用过去分词形式tired。
