Most of us spend all day at school work. After a long and busy day, all we want to do is return to a comfortable home. Smart technology can turn any home into a nicer place to live.

Smart homes have been around for some time. Scottish company Pico Electronics invented type of technology called X10 in 1975.As the earliest smart home technology, it allows household devices (設(shè)備), such as lights and alarms, to communicate with each other by using radio waves.

Of course, 5G network connectivity has made smart homes much more sophisticated (復(fù)雜) than X10. Perhaps the most widespread smart home technology is the voice-activated (聲控的) assistant. Google Home and Amazon's Alexa allow users to communicate with almost any device in their home simply by speaking a few words. This is especially convenient for children and people with physical disabilities, as they can finish tasks that would normally be too difficult, according to How-To Geek.

Common household appliances (電器) can become "smart" as well. For example, a smart trash bin can keep track of the things you've thrown away and place an online order for new items, while smart fridges can create dinner recipes (食譜) based on the vegetables that are being kept inside, according to HowStuffWorks.

But it's not just about convenience. Smart homes are also good for the environment. By regularly checking your energy use and automatically turning off lights and other devices that you're not using, smart homes can lower much electricity you use overall. Using less energy means that we use fewer natural resources, which is good for the environment.

1.The earliest smart home technology is ________.

A.X10 B.5G network connectivity C.the voice-activated assistant

2.Which is NOT true about the voice-activated assistant?

A.It can turn your home into a nicer place to live.

B.It's normally difficult for children and people with physical disabilities to use it.

C.It may be the most widely used smart home technology.

3.What can a smart fridge do?

A.Tell you how to cook. B.Place an online order. C.Create a dinner with the vegetables.

4.What does the underlined word "automatically" mean?

A.自動的 B.定時的 C.神奇的

5.Which of the following is the best title for this passage?

A.5G network changes the world

B.Smart technology makes life convenient

C.Smart homes — a nicer way of living
