When you’re not at home, many worries may start to crowd your mind. Did I turn the coffee maker off? Did I lock the door? Are the kids doing their homework or watching TV? With a smart home, you can forget all of these worries.
A smart home is a home with a communication network. This network connects(连接) devices (装置), such as lights and TV sets, and makes them to be controlled( 控制) from far away through electrical wiring( 电线), mobile phone communication or WiFi over the Internet.
More and more people may start to think about owning a smart home, because it makes life much easier. It can help keep your room at a certain temperature. It can record (录制) what happens inside the home and send the video to your phone. When you are on holiday abroad, you can use a smart home controller to switch on or off the electricity when necessary. Some smart homes can receive a visitor, allowing him to come in and offering him a drink. They can even feed the cat and water the plants.
Besides, smart homes are easy to fix. Most smart home technology and devices are wireless and can be set up with a minimum ( 最 少 量 ) of tools, using only the guiding information. When there is a problem, you can deal with it yourself without paying a professional (专业人士).
However, for home-users, the smart home technology is far from perfect. It can be rather expensive to own the technology and the devices. Also, because the smart home system ( 系 统 ) allows its owner to get home information from anywhere, it leaves the home easy to be attacked by hackers ( 黑 客 ), who may secretly use or change the information in the system.
Now, many scientists are excited about the future of smart home technology. Imagine being able to get fashion advice from your mirror, or receive food shopping suggestions from your fridge. While there are others who worry that those smart devices will make people lazier and lonelier. Whatever it is, one thing is for sure — smart home technology will change the way we live and work.

Some years ago on a hot summer day in south Florida, a little boy decided to go for a swim in the lake behind his house. He ran out of the back door, leaving behind shoes, socks and shirt as he went.
He flew into the water, not realizing that as he swam toward the middle of the lake, an alligator (鳄鱼) was getting close. The mother in the house was looking out of the window and saw the two as they got closer and closer together. In great fear, she ran toward the water, shouting to her son as loudly as she could. Hearing her voice, the little boy made a U-turn to swim to his mother. It was too late. Just as he reached her, the alligator reached him. The mother caught her little boy by the arms just as the alligator pulled his legs. That began an unbelievable tug-of-war (拔河赛) between the two. The alligator was much stronger than the mother, but the mother did her best not to let her son go. A farmer happened to drive by, heard their screams (尖叫), rushed from his truck and helped them.
Luckily, after weeks and weeks in the hospital, the little boy survived. His legs were seriously scarred (疤痕) by the terrible attack of the animal. And on his arms, were deep scars where his mother’s finger nails (指甲) dug into his arms in her effort to pull the son she loved.
The newspaper reporter, who interviewed the boy, asked if he would show him his scars. The boy lifted the legs. And then, he said to the reporter, “Look at my arms. I have great scars on my arms, too. I have them because my mum wouldn’t let me go.”
