Here is an astonishing and significant fact: Mental work alone can’t make us tire. It sounds absurd. But a 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.

Dear Editor,
I am writing tell you about the discussion we’ve had about whether it is necessary of middle school students to have mobile phones. Most students think this is more convenient for them to keep in the touch with their parents and classmates. And what’s much, it’s a fashion. However, most teachers think middle school students are not old enough to control them. It is a waste of time for students to play games and sending messages on their mobile phones. Therefore, it is easy to make students contact with each other. In my opinion, following the fashion was understandable. But as middle school student, we should put all our energy into our study.
Yours truly,
Mary

阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。

Can you tell the time on an analog clock? 【小题1】 (hope), you can! It’s the only way for you to know the time when 【小题2】 (take) exams.

However, some high schools in the UK will remove analog clocks 【小题3】 exam halls and use digital.【小题4】 instead. The reason is that 【小题5】 (teenage) are unable to read the correct time on analog clocks. They are used to seeing the time on the phone, 【小题6】 on the computer. Nearly everything they’ve got is digital.

Teachers want their students to feel as 【小题7】 (relax) as possible during exams. However, having a 【小题8】(tradition) clock in the room could make students feel stressed out during an exam Many of them might raise their hands to ask 【小题9】 time it is.

The schools are trying to make everything as easy and straightforward as possible for students during the exams. Another advantage of using digital clocks 【小题10】 (be) that students are less likely to get the time wrong.
