正确答案:D
空白后的介词on决定应选focus“(使)聚焦于某点,集中”,因为我们通常说focusone’sattention/efforts/thoughtson…“集中注意力(努力,思想)于……”;而payat—tentionto…“注意……”,所以应排除C;emphasize“强调;加强……的语气”;如,Heemphasizedtheimportanceofcarefuldriving.“他强调小心驾驶的重要性。”此词不能与attention连用;deliver“传送,交付;发表,表达”,如,Howoftenarelettersdeliveredhere?“这里一天投递几次信件?”Hedeliveredhisspeecheffectively.“他的演讲做得生动有力。”
