______ 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

Answer 1

B

試題分析：句意：由于擔(dān)心四川蘆山縣地震災(zāi)區(qū)人民的安全,李總理已經(jīng)飛往那里指揮營救任務(wù)。動(dòng)詞不定式表示目的或?qū)�來，不符合語境。concern是動(dòng)詞，故排除。這里sb be concerned about關(guān)心，擔(dān)心；這是非謂語動(dòng)詞，故用B。
點(diǎn)評：本題難度適中。主要考查的是非謂語的一些最基本的用法。但是，題目的設(shè)置注重了情景化和結(jié)構(gòu)復(fù)雜化，加大了考生對題干句的理解難度。
即學(xué)即練：__________ 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�？疾閯�(dòng)詞的非謂語形式。句意為：Andy和Ruby首先登上泰山山頂，疲憊不堪，氣喘吁吁的。據(jù)句子結(jié)構(gòu)分析，空里填的詞應(yīng)與short of breath并列作結(jié)果狀語，主語是人，因此用過去分詞形式tired。
