《2024年全科王同步课时练习九年级英语全一册人教版》

(2023.河北中考)Last week we went on a school trip to a science museum.Ms Liu,the guide,showed us around a smart home.
　　We started with the front door.Ms Liu asked me to ring the doorbell.I didn't notice the tiny camera that was fixed just above it.After I pressed(按)the doorbell,the camera sent a live video(视频直播)to the home−owners.“They can electronically open the door when they are not at home,”said Ms Liu.
　　The other thing I couldn't see on the door was a lock.“There must be one,”"I thought.At this time,Ms Liu took out a smart phone and put it against the door.And it opened.“Oh,the key is on the smart
phone."
　　
After entering the living room,I saw a computer on a table.By using the computer,the owners can control how much energy is used.In this way,they can manage their living cost.
　　One of the rooms I wanted to see most was the bedroom.To my great surprise,the bed disappeared into the floor at the touch of the smart phone.The window has a smart blind(百叶窗).It can be raised and lowered with a voice.
　　
As I left the smart home,I looked back on what I had just seen.Scientists often say that these products are improving our life.　I think the technology in the smart home may make us lazier.However,there is no doubt that it will become more popular in the homes of tomorrow.
