A thirteen-year-old boy was sitting on the sofa watching TV when the phone rang　

一个13岁的男孩正坐在沙发上看电视，这时电话响了。　

“Hello, my son.” it was his father’s voice, “where is your mother?”

“喂，儿子。”是父亲打来的。“你妈妈呢？” 　　

“Mother is working in the garden.”

“妈妈在院子里干活呢!”

“What?” barked the father, “Your mother is not as young and strong as she used to be. Why aren’t you helping her?”

“什么？”父亲吼道。“你妈已经不如从前那么强壮了。你这时怎么不在帮她？”  

“I can't.” was the reply. “Grandma is using the other hoe.”

“不行啊！”儿子答道。“另一把锄头奶奶正在用呢！”
