    Alex is reading a book about AI, artificial intelligence (人工智能).He finds the book a little difficult but very interesting. Though the word AI is very popular now, he enjoys reading it very much. He has learned a new idea about AI from the book.

When people ask AI a question, it answers the question in a very short time. So, people may feel that AI can think and answer questions as human beings do. Before Alex read this book, he believed this, too. However, this book says it will never happen. Actually, AI only uses a lot of information to get the best answer. So, when it has more information, the answer will be much closer to the perfect one. AI technologies will be cleverer tools for human beings to use. This book also says almost half of our jobs will be done by AI technologies in the near future. People will soon find more AI technologies in our lives, such as checking the tickets, the price, people's faces and fingers.

 根据材料内容选择最佳答案

① A survey(调查) has shown that lots of people can't sleep well. Sometimes you feel tired when you wake up. You may have a headache and you feel like you could sleep for another three hours. Many things around us cause sleeplessness. Here are a few changes you can make to improve your sleep.

②Go to bed and get up at the same time. You may share the same bedroom with your sister or brother. You both must go to bed regularly(规律地) so that you don't trouble each other.

③Clean up your bedroom. A study from a university in Zhengzhou found that people with clean bedrooms usually sleep better than those with dirty and untidy rooms.

④ Get more house plants. Studies show that house plants help with reducing (减轻)stress. Also, plants such as lavender(薰衣草) and gardenias(栀子花) have smells that may help some people relax and sleep better.

⑤ Make your room dark. When light hits your eyes, it tell you not to fall asleep. In fact, we need darkness especially in the evening. So if you want your body to know that it's time to rest, turn off the lights about an hour before bedtime or wear eye masks. Your phone and your TV should also be thought of. You may also use the dark curtaıns(窗帘) to keep any outside light from going into your bedroom.

⑥Lower your bedroom temperature. The body becomes cooler at night, so lowering the temperature before bedtime can help you relax and fall asleep more quickly. The NationalSleep Foundation in a country says your bedroom should be about 16 ℃ to 19℃ for a good night's sleep.

 根据短文内容,回答下列问题。

Have you ever unlocked a Hello Bike? Have you ever used Meituan to order a meal? Have you ever enjoyed watching the short-form videos on Douyin? Well, if no one had invented the cell phone, none of these would have been possible.

Luckily, someone did invent the cell phone. That person is Martin Cooper, and he did that 51 years ago, in 1973.

Cooper used to work for Motorola. In the 1970s, the company was competing with AT&T, a larger company, to make a cell phone system. Cooper didn't think Motorola's product was good enough. He didn't like AT&T's idea of a car phone, either. The man wanted to give the world something new. He wanted to make it possible for people to talk on their phones anywhere.

It took Cooper and his team 90 days to design (设计) the world's first cell phone. The product was called DynaTAC. People could talk on it for 25 minutes before its battery (电池) died. The phone's short battery life wasn't a big problem, Cooper once joked. Why? Well, the phone was too heavy (1, 100 grams) to hold in hand for too long!

On April 3, 1973, Cooper made the world's first public cell phone call. He called Joel Engel, an AT&T manager. Cooper told Engel, "I'm calling you on a cell phone. It's a real, handheld cell phone." On the other end of the line, there was only silence.

Cell phones have changed a lot since that first call. They're much smaller and can do many more things. Cooper, now 96, is surprised at the progress. But the man has also kept thinking about life in the future. "I must keep learning all my life," he says. "Or I'll lose the ability to learn-that would be terrible!"
