The robot dog is about the size of an English bulldog（牛头犬） but a little wider. It has six legs instead of four. The extra legs make it more stable and help it move faster. 　　The robot is being tested in Shanghai. The robot dog can see, listen and speak with blind people. It can help them during daily trips outside and be a “friend” at home. Blind people can also use a cane（手杖） to control the robot’s walking and 目 录 导 航 Ⅱ Ⅲ Ⅰ Ⅴ Ⅳ 8 running speed. The robot can even recognize the traffic lights. 　　Li Fei and Zhu Sibin are helping test the robot. Li is totally blind and Zhu can only see a little. Zhu often uses a cane to move around. “The robot dog will make it easier to get into public places than with real guide dogs. I am happy to join in the test. It could change our lives in the near future,” Li said. 　　In China, there are about 17.31 million blind people, but there are only about 400 guide dogs. The new robot is trying to solve this problem. “We believe our robot will act as ‘a pair of eyes’ for blind people,” said Professor Gao Peng, one of the scientists. He thinks there could be a large market for these robot dogs. 目 录 导 航 Ⅱ Ⅲ Ⅰ Ⅴ Ⅳ 9 （　）16. Why do scientists develop the robot dog？ A. To help blind people. B. To improve AI technology. C.

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 the doorbell, the camera sent a live video to the homeowners. “They can electronically（用电子方法） open the door when they are not at home,” said Ms Liu. 目 录 导 航 Ⅱ Ⅲ Ⅰ Ⅴ Ⅳ 12 　　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 smartphone and put it against the door. And it opened. I realized the key was on the smartphone. 　　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, 目 录 导 航 Ⅱ Ⅲ Ⅰ Ⅴ Ⅳ 13 the bed disappeared into the floor at the touch of the smartphone. 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 lives. 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. 目 录 导 航 Ⅱ Ⅲ Ⅰ Ⅴ Ⅳ 14 20.
