Ezio takes a tour at the science museum. The museum has a new robot guide. It is tall and white. It has a round face and a blue light on its head.
埃齐奥在科学博物馆参加导览。博物馆新来了一位机器人导游。它个子很高，通体白色。它有一张圆圆的脸，头上有一盏蓝灯。
"Please follow my light," the robot says in a flat voice.
“请跟着我的灯走，”机器人用平板的声音说。
Ten people follow the robot through the planet room. They pass the magnet table. In the space room, the robot stops under a huge rocket.
十个人跟着机器人穿过行星展厅。他们经过磁铁桌。到了太空展厅，机器人在一枚巨大的火箭下停了下来。
"Welcome to the space room. Here you can see the biggest rocket in the…"
“欢迎来到太空展厅。在这里，你们可以看到全世界最大的火箭……”
The robot stops. Its blue light goes out. Its arms stay in the air.
机器人停住了。它的蓝灯熄灭了。它的双臂还举在半空中。
Everyone waits. A man taps the robot's arm. Nothing happens.
大家等着。一位男士轻轻拍了拍机器人的手臂。什么反应也没有。
"I think its battery is dead," says Ezio. He looks around for a staff member, but nobody is there.
“我想它的电池没电了，”埃齐奥说。他四下找工作人员，可是一个人也没有。
A girl of nine raises her hand. Her name is Ruth. "I know every room in this museum," she says. "I come here every Saturday with my grandmother. I can finish the tour."
一个九岁的女孩举起了手。她叫露丝。“这个博物馆的每个展厅我都熟，”她说，“我每个星期六都和奶奶来这儿。导览我可以讲完。”
Ezio looks at the others. "Why not?" he says.
埃齐奥看了看其他人。“为什么不呢？”他说。
Ruth walks to the front. She tells them how the rocket flew. At the magnet table, she shows them a trick. Two magnets push each other away if you hold them right. In the last room, she knows the best place for a photo.
露丝走到队伍前面。她讲了火箭是怎么飞的。在磁铁桌前，她给大家演示了一个小把戏：只要拿对了方法，两块磁铁就会互相推开。到最后一个展厅，她知道哪里是拍照最好的地方。
Ezio learns more from Ruth in ten minutes than from the robot.
十分钟里，埃齐奥从露丝那里学到的，比从机器人那里学到的还要多。
At the end, a woman in a museum shirt hears the story. She gives Ruth a badge that says "Guide of the Day." Ruth pins it on her coat.
最后，一位穿着博物馆制服的女士听说了这件事。她送给露丝一枚徽章，上面写着“今日导游”。露丝把它别在外套上。
Behind them, the robot's light comes on again. "Welcome to the museum," it says. "Please follow my light."
他们身后，机器人的灯又亮了。“欢迎来到博物馆，”它说，“请跟着我的灯走。”
Nobody follows it.
没有人跟着它走。
