We all do it. We all need it. Most of us need...

We all do it. We all need it. Most of us need to do it for seven to nine hours a night. It is　　 of course sleep. Many scientists believe the truth. An adult should get eight hours sleep every night. However, some people can live without feeling sleepy after as little as six hours of sleep. But other people need about ten hours a night. Babies usually sleep between 14 to 17 hours a day. Usually they only stay awake for one to three hours.

Do you take a nap (打盹) in the day? Some adults and children need to nap. This just depends on the person. One thing scientists have learned is that man is the only mammal (哺乳动 物 ) that stops himself from going to sleep. This can be bad for our bodies in many ways. Scientists believe not sleeping enough can make us eat more. And not sleeping enough can make us put on weight. Hopefully you are a good sleeper and get a good night’s rest tonight!

Most of us drink soda. Even if we know soft drinks are bad for the health. I think we need to know more about this drink that we love so much. And here are five reasons why we drink soda:

The taste could be one thing that makes us like drinking soda. It is delicious. In fact, it is so good that many people drink it with every meal.

Even if you wanted to drink something else, you would be hard to find it as displayed in stores, at fast-food chains and supermarket. You might not realize that Coke and Pepsi are everywhere until you try to stop drinking soda.

The most important thing about soda is convenient. If you want something in a hurry, it can be taken easily and convenient to drink.

Everyone in the world knows these soft drinks. Companies spend billions of dollars on advertising sodas, and put them up everywhere, in stores, restaurants, stations, museums, and even schools.

Soda may be cheaper than the fruit juice and milk. With meals, a large soda is only a dollar, and you get chips!

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 (设备), 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 (复杂) than X10. Perhaps the most widespread smart home technology is the voice-activated (声控的) 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 (电器) 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 (食谱) 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?

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.
