【正确答案】:
IF THE SPEAKER IS JOHN'S MOTHER AND SHE IS VERY PROUD OF HIM, THE WORD QUICK IS VERY LIKELY TO MEAN CLEVER OR BRIGHT. IF THE SPEAKER IS ONE OF JOHN'S PEERS AND OFTEN COMPARE HIM UNFAVORABLY WITH OTHERS, THE WORD QUICK MAY IRONICALLY BE USED TO MEAN SLOW OR DULL. 
【题目解析】:如果说话者是约翰的母亲,她为他感到骄傲,那么“quick”这个词很可能是指聪明或机灵。如果说话者是约翰的同龄人之一,经常把他与其他人作不利的比较,那么“快”这个词可能具有讽刺意味,意思是“慢”或“迟钝”。
