    Henry finds a job on a farm. He is the strongest and youngest. He eats more, sleeps more, but works

less. He doesn't like to use his head, so he knows little. He has to do some unskilled (无需特殊技能的)

work. He always says he's tired and hopes to have a good rest. So he gets less money than others.

    Winter is coming. The workers are getting ready for the next year. Only Henry does nothing. The

farmer tells him to cut down some trees in the forest. The young man has to go there with a chair. He

feels lonely (寂寞的) in the forest and is afraid of the animals. So he looks around and sings loudly.

Nobody knows what he's singing. After three days, Henry doesn't cut down any trees. The farmer feels

strange. He wants to find out how the young man is working there. To his anger (生气), Henry is sitting

on the chair, cutting the tree. "Why are you sitting here to cut the trees?" asks the farmer. "Because I

can't work if lying (躺着), sir."
