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 (疲勞).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.
【小題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.
【小題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.
【小題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.
【小題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

Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in the world? It is an increasingly urgent question, given the recent mining accidents in Sago, W. Va and Huntington, Utah. A small group of engineers and robotics experts look forward to a day in the not-too-distant future when robots and other technology do most of the dangerous mining work. 
Robotic technology, in particular, holds much promise, McAteer says, especially when it comes to mapping mines and rescuing trapped miners --- the special operations of the mining industry.
One of the first mining robots was developed five years ago at Carnegie Mellon University’s Robotics Institute. It was called Groundhog. It used lasers(激光器) to “see” in dark tunnels and map abandoned mines—some of the most dangerous work in the business. 
The latest design is called Cave Crawler. It’s a bit smaller than Groundhog,and even more advanced. It can take photos and videos and has more sensors that can detect the presence of dangerous gases. Incredibly,the robot has a real sense of logic. If it comes across an obstacle it gets momentarily confused. It has to think about what to do and where to go next. Sometimes it throws a fit just like a real person. 
The greatest problem, though, is cost. The money of the earliest research project was provided by the government, but that money had dried up, and it’s not clear where future money will come from. Partly for that reason, and partly because of advances in safety, mining is not nearly as dangerous as it was in the past. Since 1990, fatalities(致命性) have declined by 67% and injuries by 51% , according to the National Mining Association.
Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry. The robots do the most boring and dangerous jobs,but won’t get rid of the need for human workers.
【小題1】The latest robot is more advanced than Groundhog, mainly because ____.

A.it can map abandoned mines
B.it can see in the dark tunnels
C.it’s smaller than Groundhog
D.it has a real sense of logic
【小題2】The underlined phrase “throws a fit” in paragraph 4 probably means“______”
A.gets angry B.gets sick
C.becomes hungry D.becomes cheerful
【小題3】We can infer from the last paragraph that _____ .
A.robots in mines will serve much in the automotive industry
B.there will be no need for human workers in mines
C.the mine robots will have a very bright future
D.robots in mines only do some simple jobs now
【小題4】We can infer from the text that ______.
A.the mining robots do most of the mining work at present
B.groundhog can discover the presence of dangerous gases
C.experts are trying to make robots help miners with dangerous work
D.robots cannot do dangerous work in dark areas
【小題5】What can be the best title for the text?
A.Mining Accidents in America
B.Robots in Mines

Move Earth—It’s Not Science Fiction

LONDON—Scientists have found an unusual way to  prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets(彗星)in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.
This idea for improving our climate comes from a group of US National Aeronautics and Space Administration(NASA)engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.
The plan put forward by Dr. Laughlin, and his colleagues Don Korycansky and Fred Adams, needs carefully directing a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun, ”Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The Sun is certain to heat up in about a billion years and so“seriously compromise” our biosphere(生物圈)—by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation(誤算)in orbit could fire it straight at Earth—with deadly consequences.
There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position, it is“most likely the Moon would be stripped away from Earth”. This would greatly change our planet’s climate.
【小題1】What makes the scientists plan to move Earth?

A.A few comets are moving to the direction of Earth.
B.Earth’s working life is coming to an end soon.
C.Earth will become too hot for mankind to keep alive.
D.The moon is moving farther and farther away from Earth.
【小題2】If the plan is successful, Earth will have a working life of   years.
A.12 billion B.6 billion
C.18 billion D.24 billion
【小題3】What serious problems might the plan cause according to the passage?
A.The comet might hit Earth and man might lose the Moon.
B.Earth might be moved too far away and man might be frozen to death.
C.The comet might hit Jupiter or Saturn and never return to Earth.
D.Earth’s working life might be greatly shortened.
【小題4】What does the underlined word“compromise”mean?
A.Provide. B.Benefit.
C.Share. D.Endanger.

Researchers claimed that waitresses who wear red get up to 26 percent extra in tips than they would wearing other colors. However, the team finds that the sexes tip very differently—with the bigger tips coming only from male customers.
No matter what color they wear, female diners will give the same kind of amounts for service every time. Yet men, whether they realize it or not, add anything between 15 and 26 percent more to a waitress in red than they would if it was the same waitress wearing a different color.
The test was simple. Take 11 waitresses in five restaurants over a six-week period and ask them to wear the same kind of T-shirt every day but change the colors. Previous research has suggested waitresses could earn more if they acted charmingly or wore more make-up than their colleagues. But this study, by the Journal of Hospitality and Tourism Research, only changed the color of the T-shirt. Every other aspect from make-up to behavior remained the same.
When wearing either black, white, green, blue or yellow T-shirts, the size of the tips from both male and female customers was almost identical. But when they wore red, the size of the tips went up by between 15 and 26 percent from male customers, yet stayed the same from female ones. 
A total of 272 restaurant customers were studied by researchers Nicolas Gueguen and Celine Jacob for the international journal of the tourism industry.
Even as a T-shirt, it shows just how much the color red is thought, by men, to increase the physical and sexual attractiveness of woman, said the researchers.
The researchers wrote: As red color has no negative effect on women customers, it could be in their interest to wear clothes at work.
【小題1】The underlined word “identical” in Para. 4 probably means____________________.

A.different B.similarC.the sameD.close
【小題2】According to the passage, in the research by the Journal of Hospitality and Tourism Research waitresses could earn more by _________________.
A.wearing red T-shirts
B.putting on attractive make-up
C.changing the color of T-shirts
D.behaving themselves
【小題3】Which of the following is right according to the passage?
A.Bright color can increase the physical and sexual attractiveness of women.
B.Waitresses in red make no difference to female customers.
C.Make-up makes no difference to man customers.
D.Whether male customers tips more or not depends on service.
【小題4】What is the main idea of the passage?
A.People tip differently if waitresses wear different make-up.
B.Waitresses who wear red get more tips than they would wearing other colors.
C.Male customers are more interested in the red color.
D.Red color has no negative effect on female customers.

(2013·高考福建卷,B)Your glasses may someday replace your smartphone,and some New Yorkers are ready for the switch.Some in the city can’t wait to try them on and use the maps and GPS that the futuristic eyewear is likely to include.
“ I’d use it if I were hanging out with friends at 3 a.m.and going to the bar and wanted to see what was open,”said Walter Choo,40,of Fort Greene.
The smartphone­like glasses will likely come out this year and cost between $250 and $600,the Times said,possibly including a variation of augmented(增強(qiáng)的) reality,a technology already available on smartphones and tablets (平板電腦) that overlays information onto the screen about one’s surroundings.So,for example,if you were walking down a street,indicators would pop_up showing you the nearest coffee shop or directions could be plotted out and come into view right on the sidewalk in front of you.
“As far as a mainstream consumer product,this just isn’t something anybody needs,”said Sam Biddle,who writes for Gizmodo.com.“ We’re accustomed to having one thing in our pocket to do all these things,”he added,“and the average consumer isn’t gonna be able to afford another device (裝置) that’s hundreds and hundreds of dollars.”
9to5Google publisher Seth Weintraub,who has been reporting on the smartphone­like glasses since late last year,said he is confident that this type of wearable device will eventually be as common as smartphones.
“It’s just like smartphones 10 years ago,”Weintraub said.“A few people started getting emails on their phones,and people thought that was crazy.Same kind of thing.We see people bending their heads to look at their smartphones,and it’s unnatural,”he said.“ There’s gonna be improvements to that,and this a step there.”
【小題1】One of the possible functions of the smartphone­like glasses is to ________.

A.program the opening hours of a bar
B.supply you with a picture of the future
C.provide information about your surroundings
D.update the maps and GPS in your smartphones
【小題2】The underlined phrase“pop up”in the third paragraph probably means“ ________”.
A.develop rapidly

As they migrate (遷移), butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind.
Fascinating as their skills of flight are, migrating behavior has been difficult to study in   insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect (測(cè)出) such little creatures at such great heights.
To their surprise, though, the insects weren’t passive travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes.
Even in the spring, when most winds flowed northward, the insects didn’t always go with the flow. If breezes weren’t blowing in the exact direction they wanted to go, the insects changed their body positions to compensate (補(bǔ)償). Many migrating birds do the same thing.
The study also found, butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help when farmers decide when to spray their crops.
【小題1】What’s the main idea of the text?  

A.Insects migrate with the seasons. 
B.Wind helps insects greatly in migrating. 
C.Windsurfing insects have real direction. 
D.Scientists have trouble in observing insects. 
【小題2】Scientists originally thought that ________.
A.insects always waited for their favorable winds 
B.insects chose the winds they wanted to ride 
C.insects were just blown about by the wind 
D.insects positioned themselves in the winds 
【小題3】It is not easy to study the migrating behavior of the insects because ________.         
A.the little creatures can fly very fast 
B.they have no regular migrating courses 
C.the wind’s direction is hard to foresee 
D.their flight is long and high above ground 
【小題4】We can learn from the text that _________.          
A.insects fly in the way birds do 
B.insects travel more easily in autumn 
C.insects never position themselves when flying low 
D.insects rest a lot when the wind pushes them along 
【小題5】According to the passage, the findings can__________.             
A.increase insects in number B.instruct farmers when to spray

 Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don’t agree with them.
Waste can bring a lot of problems. Although China is rich in some resources(資源), we are short of(缺乏) others, for example, fresh water(淡水). It is reported that we will have no coal(煤) or oil to use in 100 years. So if we go on wasting our resources, what can we use in the future and where can we move? Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.
In our everyday life, we can do many things to prevent waste from happening, for example, turn off the water taps(水龍頭) when we finish washing, turn off the lights when we leave the classroom, try not to order more food than we need, and so on. Little by little, everything will be changed. Waste can be stopped one day, if we do our best.
【小題1】From the passage we know that some students often _______ in the school.

A.eat too much B.don’t work hard C.waste things D.throw rubbish everywhere 
【小題2】Which is not mentioned in this passage?
A.Fresh water. B.Forest. C.Oil. D.Coal. 
【小題3】What may happen in 100 years?
A.We may still have enough oil. B.We may still have enough coal.  
C.We may have a little oil. D.We may have no coal or oil to use. 
【小題4】Which is the best title of this passage?
A.Stop Wasting B.School life 
C.Waste in the School D.Rich Resources in China
