Here is an astonishing and significant fact: Mental work alone can’t make us tire. 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 would find it full of fatigue toxins(毒素) 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 effort 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(情绪的) 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 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 amazed 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 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’ idea?
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

高二英语阅读理解简单题查看答案及解析
The human face is a remarkable piece of work. The astonishing variety of facial features helps people recognize each other and is vital to the formation of complex societies. So is the face’s ability to send emotional signals, whether through an unconscious red face or the artifice of a false smile. People spend much of their waking lives reading faces, for signs of attraction, hatred, trust and fraud. They also spend plenty of time trying to hide true feelings or intentions.
Technology is rapidly catching up with the human ability to read faces. In America facial recognition is used by churches to track worshippers’ attendance; in Britain, by retailers to spot past shoplifters. In China, it confirms the identities of ride-hailing drivers, permits tourists to enter attractions and lets people pay for things with a smile. Apple’s new iPhone is expected to use it to unlock the home screen.
Set against human skills, such applications might seem incremental(增值的). Some breakthroughs, such as flight or the Internet, obviously transform human abilities; facial recognition seems merely to encode(编码) them. Although faces are unique to individuals, they are also public, so technology does not, at first sight, interfere with something that is private. And yet the ability to record, store and analyze images of faces cheaply, quickly and on a vast scale promises one day to bring about fundamental changes to opinions of privacy, fairness and trust.
Start with privacy. One big difference between faces and other biometric data, such as fingerprints, is that they work at a distance. Anyone with a phone can take a picture for facial-recognition programs to use. Facebook's bank of facial images cannot be used by others, but the Silicon Valley giant could obtain pictures of visitors to a car showroom, say, and later use facial recognition to serve them ads for cars. Law-enforcement agencies now have a powerful weapon in their ability to track criminals, but at enormous potential cost to citizens’ privacy.
The face is not just a name-tag. It displays a lot of other information—and machines can read that, too. Again, that promises benefits. Some firms are analyzing faces to provide automated diagnoses of rare genetic conditions, far earlier than would otherwise be possible. Systems that measure emotion may give autistic(孤独症的) people a grasp of social signals they find difficult.
1.Which of the following statement about facial recognition is true according to the passage?
A. It is widely applied by Chinese in many fields.
B. It is applied to track worshippers by American churches.
C. It has been applied by Apple to unlock home screen.
D. It is applied to catch thieves by police.
2.What does the third paragraph mainly talk about?
A. Flight and the Internet surely transform human abilities.
B. Facial recognition will cause fundamental changes to minds.
C. Facial expressions are not only unique but also public.
D. Facial recognition has just the same effects as other breakthroughs.
3.From the last two paragraphs, we can infer that __________.
A. the face is superior to other biometric data
B. people can keep a balance between face and privacy
C. the face has shown many benefits especially in medicine
D. fingerprints is a powerful weapon in tracking criminals
4.What is the best title of the passage?
A. Human facial expressions B. Reading faces
C. Scientific breakthroughs D. Nowhere to hide

What is mental health?
Mental health is an expression we use every day, so it might surprise you that the term ‘mental health’ is frequently misunderstood. 1.
According to the WHO, however, mental health is “a state of well-being in which every individual realizes his or her own potential, can deal with the normal stresses of life, can work fruitfully, and is able to make a contribution to her or his community.”
2.
To make things a bit clearer, some experts have tried coming up with different terms to explain the difference between ‘mental health’ and ‘mental health conditions’, such as ‘good mental health’, ‘mental well-being’, and even ‘happiness’. 3.
As a result, some of them have tried to explain the difference by talking about a continuous whole where mental health is at one end of the range while mental health conditions are at the other.
Research shows that high levels of mental health are associated with increased learning, creativity and productivity. 4. In contrast, mental health conditions can cause distress and bad effect on relationships. They are also related to poor physical health and death from suicide.
5. The fact that someone is not experiencing a mental health condition doesn’t necessarily mean his mental health is good. Likewise, it’s possible to be diagnosed with a mental health condition while feeling well in many aspects of life.
Briefly, mental health is about being emotionally and socially healthy – the way we think, feel and develop relationships - and not merely the absence of a mental health condition.
A. So instead of being about ‘what’s the problem?’, it’s really about ‘what’s going well?'.
B. It is often mistakenly used as a substitute (替代) for mental health conditions.
C. This, however, will help prevent mental health conditions.
D. But others argue that using more words to describe the same thing just adds to the confusion.
E. They can also improve social relationships and physical health.
F. Many people are affected by depressions, anxiety and suicide.
G. But it’s important to remember that mental health is complex.
