John’s day
John is a Canadian. He lives in a tall building in the city of Toronto. There are eighteen floors in the building, and he lives on the fifteenth floor. He uses a lift to go up and down.
John works very hard. He goes to work early. Every day he leaves his home and walks to the lift.He gets into the lift. It takes him down to the first floor.
He gets out of the lift. Then he walks to a bus stop. The bus stop is in front of a station. It is about two hundred metres from his home.
Usually, he catches the number 11 bus to work, but sometimes he goes by train. John works in a factory about ten kilometres from his home, His work starts at half past eight, and finishes at a quarter to five. He gets back home at a quarter past five. He gets into the lift, and goes up to the twelfth floor. Then he gets out of the lift and climbs up to the fifteenth floor on foot.
Every day he does the same thing. Why doesn’t he use the lift for the last three floors?

约翰是个加拿大人。他住在多伦多市的高大楼房中。那是个十八层的建筑，他住十五层。他做电梯上下。

约翰工作很努力。他每天很早就去上班。每天他离开他家走向电梯。他进入电梯。电梯下到一层。

他走出电梯。然后他走到公共汽车站。公共汽车就在那有一站。从站到他家有200米远。通常，他坐11路汽车去工作，但是有时他也坐地铁。约翰在一家工厂工作，工厂离他家10公里远。他的工作在八点半开始，下午四点四十五结束。他到家是在五点一刻。他进入电梯到十二楼。然后他走出电梯自己爬到十五楼。

每天他做着相同事情。为什么他不坐电梯直接到十五楼呢？
