Most of us spend all day at school or work. After a long and busy day, all we want to do is to return to a comfortable home. Smart technology can turn any home into a nicer place to live in.
Smart homes have been around for some time. Scottish company Pico Electronics invented a type of technology called X10 in 1975. It allows household devices(设备), such as lights and alarms, to communicate with each other by using radio waves, according to AVSytemsMag, a specialized magazine in the audiovisual and automation(视听及自动化)industry.
Of course, 5G network connectivity has made smart homes more convenient. Perhaps the most widespread smart home technology is the voice-activated assistant(语音激活助手)Google Home and Amazon's Alexa allow users to control nearly any device in their home simply by speaking a few words. This is especially convenient for people with physical disabilities, as they can finish tasks that would normally be too difficult, according to How-To Geek.
Common household appliances(家用电器)can become "smart" as well. For example, a smart trash bin can memorize all the things you've thrown away and offer you a shopping list online, while a smart fridge can create dinner recipes(菜谱)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 how much electricity you use overall. Using less energy means that we make less pollution, which is good for the environment.
Not everyone is excited about smart home. In fact, …
1.X10 allows household devices to communicate by _________.
A.using radio waves B.speaking a few words
C.connecting 5G network D.inventing lights and alarms
2.What is Paragraph 3 mainly about?
A.Household devices designed for the disabled.
B.All types of smart household appliances.
C.Further development of smart home technology.
D.Difference between X10 and 5G network
3.How does smart home technology influence our life?
A.Smart trash bins help us find cheap but nice things online.
B.Smart fridges can create proper recipes and cook tasty food.
C.Smart homes will help us save energy and reduce pollution.
D.Smart homes make us stay at home instead of working out
4.The author may introduce the ________ of smart homes in the last paragraph.
A.use B.spread C.future D.disadvantages

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?
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.自动的 B.定时的 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

Most of us use alarm clocks to wake up at the right time for school or work. We look at our watches to know the right time for the bus or train. However, there is also a right time to eat, sleep, exercise, and take medicine, too. We can’t look at a clock for the right time for these activities. We must listen to the clock inside our bodies: the biological clock(生物钟)
Barbara Wells exercised every morning. She woke up at 6:00 am. She ran about two miles before she went to work. But Barbara’s legs and back(后背) started to hurt. She did some exercises before she ran. But her legs and back still hurt. She ran slower, but the pain didn’t stop. Barbara talked to her doctor. The doctor said,“Don’t run in the morning. Try to exercise later in the day. That is the time when your body is at the right temperature for exercises after work.” Her legs and back don’t hurt anymore.
Today, doctors are learning more about chronobiology (时间生物学),the study of biology clocks. They are learning about the importance of time for our bodies. For example, it is best for people to go to sleep at the same time every night and to eat only when they’re hungry. Also, doctors discovered that some illness, such as heart attacks(心脏病), occur(发生)most often in the morning. This information tells them that the best time to take heart medication may be at night. When patients take heart medicine at night, they may prevent a heart attack in the morning.
Many doctors believe chronobiology can help us live healthier lives. It may be the right time to listen to these doctors!
1.Do we all have a biological clock inside our bodies?
2.How far did Barbara Wells run every morning?
3.How did Barbara Wells' legs and back get well?
4.What is the right time for a heart attack person to take heart medicine?
5.What can we learn from the passage?
