A public restroom in Japan has enabled you 【小题1】 (do) some things by using voice commands---flushing（冲洗）the toilet or washing your hands. 【小题2】 is simple to use it, just saying “Hi toilet”. It’s a new restroom 【小题3】 use by anyone regardless of their gender or age.

The voice-activated restroom Hi Toilet is a way to move towards the 【小题4】 (realize) of such a harmonious society that people there eagerly accept diversity. The restroom 【小题5】 (propose) by Kazoo Sato uses voice commands to control functions like opening the door and flushing the toilet. The idea for the Hi Toilet was in place long 【小题6】 the widely spread disease hit, but that just makes the hands-off restroom more 【小题7】 (time).” After three years of work, we came up with the concept of the voice-command toilet,【小题8】 functions could be activated by voice,” Sato said.

While the toilet 【小题9】 (equip) with a custom command system in Japanese, it will also respond to English speakers. It could also be programmed with additional languages. The interactive experience is 【小题10】 (true) like talking to a chatbot（聊天机器人）.

Science and Technology

Thanks to science and technology, we now live conveniently in houses 【小题1】 (furnish) with modern household appliances; we can travel a long distance in the fraction of a second on planes, trains and cars 【小题2】 (comfortable).

Science and technology 【小题3】 (bring) us too many benefits so far. Take online services for example. We don’t have to wait for hours in queue to pay bills, withdraw money, or book hotels. All of these can be done at home, 【小题4】 is really time-saving and labor-saving. A wide range of 【小题5】 (product) can also be purchased online and then delivered at your doorstep and 【小题6】is true that our way of living has been revolutionized and the lives of millions of people have been changed due to science and technology.

【小题7】, many problems also arise with the 【小题8】 (develop) of science and technology. The environment is being polluted, resources are being over-exploited, and people suffer from great psychological pressure due to the fast pace of life.

Therefore, science and technology, viewed as 【小题9】 two-edged sword, presents us with both conveniences and troubles. But shall we give up eating for fear of choking? It’s high time we took action to make 【小题10】(good) use of science and technology than now.

Scientists say soft robot jellyfish that can swim through openings 【小题1】（narrow） than their bodies could be used to observe coral reefs. In future the “jellybots” could be sent into delicate environments, such as coral reefs, without risking damage. Their creators believe they could act 【小题2】 “guardians of the oceans”.

Dr Erik Engeberg, one of the robot’s 【小题3】（inventor） from Florida Atlantic University in the US, said, “【小题4】（study） and observing delicate environment has always been hard for researchers. Soft robots can help with this.”

The design of the jelly bot is based on 【小题5】 shape of the moon jellyfish. The team used a system 【小题6】（drive） by two impeller pumps（叶轮系） to allow the robot to swim.

Dr Engeberg said, “Soft robots based on fish and other sea animals 【小题7】（win） popularity in the research community in the last few years. Jellyfish, are excellent choices,【小题8】 that they are very efficient swimmers. Their 【小题9】（perform） is due to the shape of their bodies,【小题10】 can produce a combination of vortex（漩涡） and jet propulsion（推进）.”
