The next morning, Tom went into the exam room very early. He found a young man who looked so confident and took a seat next to him. "Hey your" Tom greeted. "What?" The young man asked.
"Can you do me a favor?" Tom begged(恳求), "Please let me copy your paper(试卷)during the exam. I have to depend on you!" When hearing his words, the young man just smiled but said nothing.
