第7章 That Was an Echo
"Good grief, you've got the biggest cavity I've ever seen!"the dentist exclaimed as he examined a new patient.
"The biggest cavity I've ever seen!"
The patient snapped, "You don't have to repeat it."
"I didn't. "replied the dentist,"That was an echo."
那是回声
“天啊，你的牙洞是我见过的最大的牙洞！”牙医一边检查新来的病人，一边惊叫道。“我见过的最大的牙洞！”
病人脱口说道：“你不必说两遍。”
“我没有呀，”牙医回答说，“那是回声。”
