There are many ways to help improve your health like eating healthy food. Taking exercise and getting medical help. But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night. The general sleeping rule is that the younger you are, the longer sleep you need. But regardless of(不管)age, some people need to sleep more while for some a few hours is enough.

The problem with sleep is that more and more people in the world are not sleeping enough. According to the World Health Organization over half the people in the world may be sleep-deprived. Having less sleep not only makes people feel tired but also causes accidents. In the United States alone, sleepy drivers cause at least 100,000 traffic accidents a year. Also sleep problems can cause medical problems such as high blood pressure(血压).

Why are so many people sleep-deprived? Part of the reasons may be cultural. In the American culture, people put a higher value on work than on sleep. In fact, peopele who sleep a lot are usuallv seen as “lazy”. Also, you can sometimes hear some people say proudly that they don’t have much time to sleep. they only sleep four or five hours a night. It seems that the less you sleep, the more work you’ll do.

How do we teach these people to learn the value of sleep? Perhaps they may listen to the advice of Dr. James Maas an expert (专家) in sleep. He says , “Sleep is like a credit (信用卡) card. When you sleep less. you are only borrowing time. You always have to pay it back. The morehours you don’t sleep, the more hours you should t sleep to ‘pay back’ the hours on your ‘sleepcredit card.’”

For those who value work more than sleep, they should listen to what a famous person once said. “Don’t think you will be doing less work because you sleep during the night. That is a foolish(愚蠢的) idea which is held by people who have no imagination. You will be able to do more.”

Imagine you are thinking about entering a senior high school, but have questions. So you go to the school's website to find answers. A message appears on your computer and says, "How can I help?" You are not communicating with a human being, but a chatbot. It is using artificial intelligence (AI) to communicate with you. This might sound strange, but in recent years, chatbots have become an usual tool for banks and large companies around the world.

Having workers answer people's questions and complaints can be expensive. And workers canonly work several hours a day, making customers wait longer for a response (答复). So not only companies, but more schools have also begun using chatbot technology, says Keith Rajecki. He is with Oracle Higher Education, a computer software company that serves these institutions.

Rajecki notes that reducing costs and response time is one of the main reasons why schools and companies are turning to this technology. However, the purpose of many schools is to find ways to better serve students, since students are used to communicating online through Facebook or WeChat, says Rajecki.

Now Oracle is offering many schools a chatbot which can do everything from helping students register (注册) for classes to helping them ask for a few days off. Oracle is not the only company working on chatbot technology. Businesses like AdmitHub and Ivy.ai are involved in similar efforts.

Western Governors University, or WGU, also received a $750,000 award to experiment with a new kind of chatbot. "We're not trying to create a bot that answers simple questions," said Jason Leven, the director of WGU Labs. "We're trying to create a chatbot that can help decision making for students."

Ian Jacobs is with the market research company Forrester. He suggests that technology like chatbots can work well if it is able to do what users ask of it. Jacobs says the problem will appear when cost cutting becomes an important reason for using the technology. This means schools and companies are more likely to try using chatbots for things they are not yet able to do, such as communicating in the way humans do. For one thing, there are hundreds of ways to word even simple requests. For another, chatbots aren't able to deal with emotions (感情). They can't understand how humans feel, not to speak of comforting (安慰) them.

1.Which of the following is not the reason why more schools are turning to chatbot technology?

A.Schools want to serve the students better.

B.Chatbot technology can help schools save money.

C.Students are used to communicating with chatbots.

D.Chatbot technology makes students wait shorter for a response.

2.Chatbots may work well in the following situations except ________.

A.when students want to know more about a school

B.when students are wondering how to register for classes

C.when students want to have two days off because of illness

D.when students are in need of some help because a parent dies

3.The following sentence would best be placed at the end of ________. However, not everyone is ready to consider the possibilities this kind of technology presents.

A.Paragraph 5 B.Paragraph 4 C.Paragraph 3 D.Paragraph 2

4.What can we infer from the passage?

A.A chatbot is able to do whatever users ask of it.

B.A chatbot is a kind of completely new technology using AI.

C.A new chatbot may appear to help students to make decisions.

D.Chatbot technology has been used in both schools and companies.
