    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 door-bell. 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.

    1. (1) Where did Ms. Liu show the students around a smart home?
    2. (2) What can the home-owners do if they are not at home and others ring the doorbell?
    3. (3) How can the owners control how much energy is used?
    4. (4) What does the writer think of the technology in the smart home?
