A robot asks for hugs
Lovot is a special robot from Japan. It can give people comfort and warmth. It looks like a mix of a penguin ( 企鹅), an owl, and a teddy bear. Lovot has a camera on its head. It can remember about 1,000 faces. Wheels under Lovot's body help the robot move around. The fun thing about Lovot is real-human. It can ask for a hug by opening its arms and waving to you, just like a baby. |
_____________.
To young children, a year might seem to last forever. But older people might say that it flies by. Why is that? According to US scientists, young people's brains process information at a faster speed than older people. They take in more information and do more things in a day. Therefore, they feel like each day lasts longer. However, older people's brains degrade (退化) as they age. They take in less information and thus see a day pass more quickly. |

Taking 10,000 steps a day
You may have heard that walking 10,000 steps a day is good for your health. But is that true? In fact, there is no official recommendation to walk this much, US scientists said. It was an idea from an advertisement for Japanese pedometers (计步器) in the 1960s. Scientists suggest that people can have 150 minutes of moderate activity a week, such as quick walking. As a result walking about 7,000 to 8,000 steps a day is a good choice. |
