Have you ever thought about keeping a pet goldfish? First you need to know how to keep it.
Get a fishbowl（鱼缸）— First get a fishbowl. Make sure the fishbowl is large enough for the goldfish to swim in. You should keep the fishbowl clean. Don't clean the fishbowl with soap. Hot water will clean it well.
Feed a goldfish — Goldfish eat almost any food. And you can also buy some special food for your goldfish in shops. Do not feed it too much food. Feed it as much as it can eat in three minutes one time.
Keep the water clean — Dirty water is not good for the health of the goldfish. If the water is dirty, the goldfish will easily get sick and may die. Change 25% of the water at least once a week. Never change all of the water because it includes something that your goldfish needs.
As you can see keeping goldfish as pets is not difficult.

Saya was a life—like woman robot. She started her work as a teacher at a primary school in Tokyo, Japan days ago. She gave lessons to the students there. You won't hurt it if you touch（触摸）it, hit or play with it.
The scientist who built Saya said, "We didn't want Saya to do all the work of a teacher, but to build this robot to teach children about technology（技术）. And Saya may be a help to the schools which have not enough teachers."
"In some villages and small schools, there are children who know little about new technology. There are also some teachers who can't teach these lessons. So we hope the robot can make the children become interested in new technology." said the scientist.
Many of the children were very excited when Saya came to school. They liked to listen to her report. When class was over, some students touched her face and felt her.
The scientists in Japan hope that they can make some robots to look after the older people in the future.
