Next to him was his younger brother, Paul. “Mark, when will we have a Christmas tree?” Paul asked. “I’m looking forward to decorating it with Mom’s straw birds.” “This year we won’t have a tree, Paul.” “Why not?” “Too many bills with Grandpa’s sickness. Mom said we couldn’t buy one.”
There was a knock at the door of their flat, and they rushed over to find out who it was. It was Jack from downstairs. He was admitted into the flat, and he glanced about. “You don’t have any trees? I helped to place the artificial tree last week. It’s up to the ceiling. There are only two more days until Christmas! I don’t think you’ll get a tree.” Paul was unconvinced by Jack’s words. “Definitely not! We’re going to buy a genuine(真正的) Christmas tree, a genuine one!” Jack shrugged his shoulders and walked away.
Mark made his way back to his bedroom, shaking his piggy bank. That was only $7 in it. With school out, he thought, he would be able to make enough money in the next couple of days to get a tree and give Mom a surprise.
On the second day, Mark was busy transporting goods to assist the customers. When he was gone, he make another $6 in his pocket. It was his lucky day, and he had expected to spend $13 purchasing(购买) a little tree.
He whistled all the way to the tree lot(场地). But even the smallest one cost $15 or more. There would be a lot of shopping tomorrow, and he would make the extra dollars. He said to the seller in the tree lot, “Would you please help me keep this tree?” “ I cannot,” the seller said, “but come back tomorrow. Maybe it’s still here.” “I’ll return.” Mark waved his hand and ran away.
