NAO is a 58cm-tall robot. He is small, cute and round. You can't help but love him! NAO is created to be a friendly partner around the house. He moves, recognizes (識別) you, bears you and even talks to you.

Since his birth in 2006, he has been better and better at pleasing, understanding and loving you.

Maybe one day he will become your friend. His cute look and wonderful communication skills make him really lovely and popular.

He can be a good helper. Ask him to do something and he does. For example, ask NAO to wake you up in the morning, to watch your home during the day or to teach you new things whenever you want. You no longer need a keyboard, a computer or a mouse to communicate with technology. All you have to do is to talk to him.

He can be a sweet family member. He can learn to read your moods, so that he always knows the right thing to say. He can recognize your family members and call them by their first names. You can teach him how to choose the music, food and film you like best.

Sleep is like food for the brain. 【1】

People of different ages need different amounts (數(shù)量 ) of sleep. According to the National Sleep Foundation (國家睡眠基金會) in the US, adults should get seven to eight hours of sleep a night 【2】 And school-aged children may need more than ten hours of sleep.

【3】 The China Youth and Children Research Center said that about 80 percent of middle school students don't get enough sleep. It has influenced students' school life. 【4】 They can't pay attention in class or do well in sports.

To solve this problem, scientists advise that students should get less schoolwork and more time to sleep. 【5】 Good sleep habits help a lot. For example, try to go to sleep and wake up at the same time every day, even on weekends and during holidays.

At 430 meters below sea level, the Dead Sea is Earth's lowest point on land. It is popular for its wonderful buoyancy(浮力). The high salt content-more than 34 percent - makes swimming more like floating.

Now the Dead Sea is actually dying. People are using water from the Jordan River, which takes water away from the Dead Sea. Since 1930, its surf area has reduced by almost 40 percent.

Venice, Italy

With waterways instead of streets. This "Floating City" has attracted visitors for centuries. But no visit to Venice is complete without a ride on one of its famous gondolas, human powered

water taxis. Water creates Venice. But water will also kill the city.

Built on soft earth, Venice has slowly been sinking (下沉) for centuries. Now, with rising sea levels caused by human activities, it's sinking faster. According to US-based magazine Architectural Digest, the city may disappear in the next 100 years. Better book your gondola soon!

Great Barrier Reef, Australia

Covering more than 2,300 kilometers of Australia's northeast coast, Great Barrier Reef is the world's largest reef ecosystem, and an ideal place for scuba divers (水肺潛水者).Thousands of colorful coral (珊瑚) and fish make homes in the blue sea water. It's like a big underwater party!

Sadly, the party might be over soon. The reef is dying. Human activities are changing the weather. Warming ocean, water kills the coral, and this causes problems up the food chain. The New York Times reported that large parts are already dead, and the reef system might be gone by 2030.

【題目】

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（設(shè)備）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（增長）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?

A. can look after the babyB. can cook delicious food
