LITTLE Johnny came downstairs with tears in his eyes. “What’s the matter now?” asked his mother. “Dad was hanging pictures, and had just hit his thumb (拇指) with a hammer (锤子),” said Johnny through his tears. “That’s not so serious,” soothed (安慰) his mother. “I know you’re upset, but a big boy like you shouldn’t cry at something like that. Why didn’t you just laugh?” “I did!” cried Johnny.
