A Smart Home

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 television? With a smart home, you can quiet all of these worries.

A smart home is a home with a communication network. This network connects devices(装置), such as lights and TV sets, and allows them to be controlled from far away through electrical wiring, mobile phone communication or WiFi over the internet.

More and more people may start to consider owning a smart home, because it makes life much more convenient. It can help keep your room at a certain temperature. It can record what happens inside the home and send the video to your phone. When you are on vacation 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 of tools, using only the guiding information. When a problem appears, you can deal with it yourself without paying a professional.

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 allow

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 at the future of smart home technology. Imagine being able to get fashion advice from your mirror, or receive food shopping suggestions from your refrigerator. 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.

Pictures That Don’t Last

“YEARS ago when I was at the Grand Canyon, I remember someone coming up to the canyon’s edge, taking a shot with their camera and then walking away, like ‘got it – done’, barely even glancing at the magnificent (壮观的) scene sprawling (展开) in front of them,” Linda Henkel, a scientist at Fairfield University, US told Live Science.

Henkel was surprised by how obsessed (着迷的) people are with taking pictures these days – before dinner, during friends’ birthday parties, on museum tours and so on. You know people just like that, don’t you?

They keep taking pictures because they think that it helps record the moment, but as Henkel’s latest study has just found out, this obsession may prevent their brains from remembering what actually happened, reported The Guardian.

In her study, Henkel led a group of college students around a museum and asked them to simply observe 15 objects and to photograph 15 others. The next day the students’ memory of the tour was tested, and the results showed that they were less accurate in recognizing the objects and they remembered fewer details about them if they photographed them.

“When people rely on technology to remember for them – counting on the camera to record the event and thus not needing to attend to it fully themselves, it can have a negative effect on how well they remember their experiences,” Henkel explained.
