B 根据下面短文回答下列问题。 Every winter, Ben goes skiing(滑雪) in the mountains near his home. He has got a dog, called "Hippo". Hippo also loves running in the snow. They always go skiing together. Last year, Ben fell (摔倒) and broke his leg when he was skiing. He went to a hospital and had to stay there for three weeks. His family brought him sweets to eat and story books to read, and the doctors were very nice. Ben enjoyed staying in the hospital. When he went back home, the doctors asked him not to walk but to rest for some time. Ben didn’t want to stay in the house all day. He wanted to go skiing. So he bought a sledge (雪橇). He and Hippo went "skiing" — this time they sledged all day. Ben lay (躺) on the sledge and Hippo pulled (拉) him.

Ben enjoyed staying in the hospital, so he stayed there for more than three months.
