Here is an astonishing and significant fact: Mental work alone can't make us tired. It sounds absurd. But a few years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue(疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we could find it full of fatigue toxins(霉素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.

So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of efforts as at the beginning. The brain is totally tireless. So what makes us tired?

Some scientists declare that most of our fatigue comes from our mental and emotional(情感的) attitudes. One of England's most outstanding scientists, J. A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems.”

What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated—those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.

1.What surprised the scientists a few years ago?

A．Fatigue toxins could hardly be found in a laborer's blood.

B．Albert Einstein didn't feel worn out after a day's work.

C．The brain could work for many hours without fatigue.

D．A mental worker's blood was filled with fatigue toxins.

2.According to the author, which of the following can make sitting workers tired?

A．Challenging mental work. B．Unpleasant emotions.

C．Endless tasks. D．Physical labor.

3.What's the author's attitude towards the scientists' ideas?

A．He agrees with them.

B．He doubts them.

C．He argues against them.

D．He hesitates to accept them.

4.We can infer from the passage that in order to stay energetic, sitting workers need to ________.

A．have some good food

B．enjoy their work

C．exercise regularly

D．discover fatigue toxins

You use her as a shoulder to cry on. She texts you back with casual jokes. But she, Xiaoice, is only a virtual chatbot（虚拟聊天机器人）.

Xiaoice, Microsoft’s latest artificial intelligence robot, was briefly released in 2014, and returned to WeChat in 2015, where she became a big hit. Millions of young Chinese now exchange messages with her daily, The New York Times reported. On WeChat, Xiaoice is an official account. After following it, users can start text-based conversations with Xiaoice.

“Her incredible learning ability was why people loved to talk with Xiaoice,” Liu Jinchang, a researcher at High-tech Research and Development Center under the Ministry of Science and Technology, told China Daily. Apart from her ability to identify photos and send emojis（表情符号） in conversations, Xiaoice gains 45 percent of her knowledge from interacting with users, China Daily reported.

Chatbot programs first appeared in the mid-1960s in the US. Driven by top tech companies, they are becoming smarter and more common. For instance, IBM’s latest artificial intelligence program served as an academic consultant at Australia’s Deakin University, answering students’ questions about course schedules and financial aid. Apple’s Siri and Amazon’s Alexa have been used as voice assistants who can read news, play music and even make jokes for their users.

These programs are expected to move beyond smartphones, into televisions, cars and living rooms, The New York Times pointed out. However, it may take decades before scientists develop a “Samantha”, the advanced chatbot seen in the fiction film Her. In the film, Samantha has a romantic relationship with her user played by US actor Joaquin Phoenix. Many viewers were enthusiastic about this fantasy of virtual soul mates.

1.What does the underlined part in Paragraph 2 mean?

A. She became a best seller.

B. She became very powerful.

C. She became a money maker.

D. She became very popular.

2.Which of the following can Xiaoice do?

A. Do housework.

B. Spread messages.

C. Identify various photos.

D. Read news to its users.

3.Which company’s chatbot program can act as an academic consultant?

A. Microsoft. B. IBM. C. Apple. D. Amazon.

4.What can be learned from the last paragraph?

A. Chatbots will be applied to cars soon.

B. Chatbots mainly run on smartphones now.

C. Samantha is played by a US actor in the film.

D. The film Her doesn't interest many audience.
