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(系统) 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.

   We talk every day. When we have good news, we like to share it with our good friends and when something terrible happens, we make it known to others soon. But can you imagine that a tree can talk and share hews too? Of course, no tree moves lips and says words just as people do. Strange as it may sound, though, some trees do manage to communicate with each other.
   Willow(柳树) trees are the best-known of these trees. When insects(昆虫) begin nibbling(叮咬) a willow tree, the tree sends out a special smell at once. This smell tells the other willows that harmful insects are coming near. All of them quickly make a chemical(化学物质) in their leaves. This chemical is bad to the insects. The insects do not like it and they fly away soon. In this way, the willow trees protect themselves from the insects.
   The next time when you take a walk in the woods, maybe the trees are “talking” to each other quietly. And when someone says that trees cannot “talk”, please tell them that even trees give messages to each other, too.

Before you can start speaking and writing in English, your brain must get enough correct English sentences. This is obvious（显而易见的）.
There are two ways to get correct English sentences: listening and reading. Both are good, but reading is much easier than listening. With the help of a good dictionary, you will be able to understand English texts much more easily than movies. If you just read one book in English, you will see that your English has become much better. English phrases will just come to you without thinking when you are writing or speaking.
This is true for hundreds of words and grammar structures（结构）. If you read in English, you can forget about grammar rules. Throw away your grammar book! You needn't know the rules for the present perfect tense(现在完成时). Instead, read a few books in English, and soon you will feel that “I have seen Paul yesterday” is wrong. The only difference between you and native speakers is that they have heard and read more English sentences than you have.

      Roosegaarde, an artist and designer from Dutch has thought of a device(装置). He hopes it will make Beijing's sky clear again and help the people with masks breathe fresh air again in Beijing.
     An electromagnetic field(电磁场) will pull the dirty particles in the air to the ground, and then they can be easily cleaned.
Roosegaarde says, "It's like when you have a balloon which has static electricity(静电) and your hair goes toward it. Smog happens the same way as the hair."
      His workplace has reached an agreement with the Beijing government to test the technology in one of the capital's parks. Beijing's skies are regularly covered by grey smog. Serious cases of air pollution are often reported in Beijing. Roosegaarde says an indoor test has already shown it works well and he is confident of the results. With the help of a team of scientists and engineers, he is sure that the device can be worked outside.
     "Beijing is a very good place to test the device because the smog in Beijing is quite low and there's not so much wind." says Roosegaarde. "We'll be able to make the air pure but the most difficult thing is to remove the smog. As a result, you can see the sun again."
     Roosegaarde also reminds us that his aim is not only to give a plan to solve Beijing's dirty air pollution but also to make people pay attention to the environment problem. He adds, "This is not the real answer for smog. The real answer to do with it is clean cars, different industry and different lifestyles. " However, he hopes the project will make the citizens realize the differences between clean air and smog-filled air.

Today, many endangered animals live in zoos. There, scientists work to keep each species(物种) alive. How do they do that? One way is by taking cells(细胞) from animals. Then the cells are frozen(冷冻). They can be used in the future to help animals reproduce.

The San Diego Zoo has been freezing cells for 40 years. It's also called the Frozen Zoo. Now, the zoo is the biggest of its kind, with a large gene bank. It has cells from more than 1,000 species. One of the species is the northern white rhinoceros(犀牛).

There are only five northern white rhinoceros alive in the world now. They are unable to have their children. Some scientists there want to use the bank's frozen cells to produce another northern white rhinoceros. They want to do this before the species dies out. That could happen by 2025.

Can the zoo save the northern white rhinoceros? Other species have been saved successfully. So it's possible for the white rhinoceros too.

Saving the white rhinoceros would be expensive. So some people don't think using frozen cells is the best thing to do. Some wonder whether it's worth spending millions of dollars on the species that nearly dies out. Some say scientists should work on the reasons why animals become endangered in the first place.

What's sleepwalking(梦游)？Sleepwalking usually happens in the first few hours of sleep. Not all sleepwalkers walk when they are sleeping. Some just sit up or stand on the bed. Some even get up and walk around for a few minutes or half an hour. Some do things as if they were awake, but in fact they are not!

Sleepwalkers' eyes are open and they usually go back to beds by themselves. But they won't remember it the next morning.

About 15% of kids sleepwalk. Sleepwalking sometimes happens when a person is ill or worried, or doesn't get enough sleep. If sleepwalking happens often, you should see a doctor. If it doesn't, you don't need to worry. Here are some ways to help stop sleepwalking:

Listen to some music and relax before going to bed.

Go to bed at a regular time every night. keep your bedroom quiet and dark when you try sleeping.

Brooke wanted a dollhouse and some sugar cookies. So the 6-year-old asked Alexa to get them. Alexa wasn't her mom or babysitter. It was a voice-activated home assistant powered by AI (人工智能). And it made Brooke's wishes come true. A few days later, much to her parents' surprise, a $170 dollhouse and four pounds of cookies showed up. They ate the cookies and gave away the dollhouse to a local hospital. And that's not the end of the story. When a news reporter told the story of what happened on TV, Alexa devices (设备) in many listeners' homes woke up and tried to order dollhouses!

Alexa isn't the only AI willing to serve you. Apple Home Pod has Siri, Google Home has its Assistant, and the upcoming Galaxy Home device will have Bixby. People who have these devices use them mainly for listening to music, checking the weather, and setting timers. According to a report from The Information, nowadays voice shopping is rare. But many scientists predict a boom (增长) in voice shopping in the near future. Is that a good thing?

▲ You can shout out an order as soon as you think of it, even if you are cooking, cleaning, or driving. In addition, people with disabilities who are unable to use a keyboard or mouse can shop without any help.

But voice shopping has its disadvantages. Unwanted dollhouses aren't the biggest problem. It's usually very easy to cancel an order or return products. The thing that worries some people is that these assistants are always listening. They have to be able to respond when you want them. So they listen for "Alexa" or "OK Google" or another order. When they hear it, they start recording the conversation. Some have worried about what happens shopping habits? And what if someone hacks (入侵) the device? The CIA found a way to hack smart TVs to turn them into spies that listen all the time. Others could do the same with any smart device.

What do you think? Are you ready to start voice shopping?
