三、阅读理解。
Can people have tails(尾巴)? Yes. Scientists at Keio Uni- versity in Japan have built a robotic(机械的) tail. It can help old people keep their balance.
The tail is 1 meter long. People can wear it around their waist(腰). The tail keeps balance like a pendulum(钟摆). When people walk one way, the tail moves in the oth- er direction.
The robotic tail works like a seahorse’s(海马的) tail. It has a set of plastic vertebrae(塑料椎骨) that help it move easily. If it feels too heavy, people can take out some of its parts.
Since some old people can’t walk steadily(平稳地), this tail can help them get around. The tail could also help workers keep their balance while carrying heavy things. It could also give gamers a better experience when they play virtual reality(虚拟现实)games.
Animals' tails are useful. They not only help them keep their balance, but also have other uses.
