题目内容：

    Do you want a pet, but worry about taking care of it? Aibo might be a good choice for you. Aibo is a robot(机器人) dog. It is made by Sony. It isn’t as difficult to take care of as a real pet.

Aibo’s artificial intelligence(人工智能) makes it act like a real dog. It can wag(摇摆) its tail, shake your hand and play a ball. Aibo can move its ears back and forth. It can also blink(眨眼) its eyes. There are sensors(传感器) on Aibo’s head, chin(下巴) and back. When you touch it, it feels comforted(得到安慰的) like a real pet would. Aibo can understand different words, such as “sit”, “stay”, and “come”.

Another interesting thing about Aibo is that it can “learn”. The robot can remember its daily experiences. This helps it build a database(数据库). The robot can “grow” and change itself according to this database. Over time, Aibo can have its own personality(性格). This makes it more like a real pet.
