Bob's father has a big farm.On New Year's Day,he asked Bob,"Could you work on the farm when you're free this year?"
"Farming is not my work,Dad. I have much schoolwork(功课) to do."Bob wasn't glad about it."If you help me work on the farm,I will give you anything you want."
"OK."Bob agreed happily.
So Bob gets up early and works hard on the farm in his free time this year,just like other farmers.His wheat(小麦) grows very well.
Time flies.Today is December 31st,the last day of the year.The father is talking with his son."I'm happy to see you work hard on the farm,Bob.Now tell me what you want as the gift(礼物)(已经得到)your gift,Dad.You are trying to give me a lesson——no pain
