Is your TV connected to the Internet? What about your chair,or your fridge? Probably they are not. But in the future, most things in your home may be connected, thanks to the so-called “Internet of things”.

The Internet of things may be coming sooner than you think. Earlier this year, Aamsung CEO spent a lot of time talking abput the Internet things. He said that five years from now,every Samsung product will be part of the Internet of things,no matter whether it’s a remote control or a washing machine.

So, how do household(家用的) objects that are part of the Internet of things work? Well,think of a common chair. When connected to the Internet, the chair warms up when it knows the user has just walked into the room and is feeling cold.

An Internet-connected camera could help people feel safer in their homes. It can know people’s faces and has an infrared sensr(紅外傳感器),so even if it’s dark it can see when someone passes by and send you a message on your smartphone to let you know who’s there. If the person is someone you don’t know,it can tell you that ,too.

But according to MIT Technology Roview, whether companies are connecting dog food bowls or security systems to the Internet, there may be some problems. For example, many early connected-home objects don’t have much built-in security, which means they could be hacked(被黑客攻擊). Morever, it could be difficult to get these new machines to work together especially when they are made by different companies. To fight this ,many companies have joined the Open Interconnect Consortium, which had 45 menbers by late 2014.

So, picture this: you enter your home.The temperature changes to make you feel comfortable. Your favorite music starts playing for you. Do you think that this would be a good thing? I t may happen sooner than you think.

1.What does the article mainly talk about?

Should mobile phones be allowed at school?

1. Some mobile phones are more than just phones---(此處為破折號(hào))they are being used as radios, cameras (照相機(jī)) and MP4 players, and they are also used to send e-mails or surf the Internet.

If someone’s mobile phone rings during a Chinese class, he and his classmates can’t concentrate on (集中注意) what the teacher is saying. Some parents also point out that their children often use their mobile phones to download (下載) unhealthy information from the Internet. 4.

Other people believe that we can find some ways to use mobile phones to help students learn better in the classroom, since many of today’s mobile phones are like mini computers. And children usually know more than adults about how to use new technology (技術(shù)). 5.
