Here is an astonishing and signficant 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 could labor without reaching a stage of fatigue(疲劳). To the amazement of these scientists, they discovered thett blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day labourer, we could find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of Albert Einstein, it would show no fatigue toxing 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 f efforts as at the beginning. The brain is totally tireless. So what makes us tired.
Some scientists declare that most of our fatigue come 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?Satifaction?No!A feeling of being bored,anger,anxiety,tenseness,worry,a feeling of nt being appreciated---those are emotions that tire sitting workers.Hard work by itself seldom causes fatigue.We get tired because our emotions produce nervousness in the body.What surprised the scientists a few years ago?

More than one-third of adults in the United States are obese. In fact, over obesity has reached such proportions that one big-city mayor has gone about banning large-sized, sugary soft drinks and the First Lady has been on a campaign to control the dietary offerings in public schools.
Even many adults who do not fit the clinic definition of obesity are still overweight, and a large percentage are looking for the best ways to lose weight.
Reducing pounds largely comes down to the two-sided factors of diet and exercise. Not carrying out the first one enough, and not getting enough of the second one, ends up giving the individual a recipe for being overweight.
Advising someone to eat less and exercise more might be the easiest advice possible, but it’s also, partially, an oversimplification. Dieting has more to do with the types of food you eat than how much you eat. Reduce the amount of red meat in your diet. If you don’t want to eliminate red meat altogether, choose cuts of meat with less fat content. Limit your intake of salt and starches. If you’ve got to have potato chips alongside your sandwich at lunch, choose the baked potato chips that contain less fat than the deep-fried chips. You might find you’re really not sacrificing that much in terms of taste.
A diet rich in fruits, vegetables, egg whites, fish and nonfat dairy products will certainly aid in the mission of losing weight. Drink more water and less sugary drinks. If you have to have a soda, a diet soda is a better option, but seltzer is an even better choice than that.
It’s important—if not always easy—to make sure you get at least some physical activity each and every day. If your feet won’t allow for a regular jogging regimen, then make sure you take lots of walks. Next time you need to mail a letter, walk to the mailbox instead of driving. Try to work in a daily walk in your neighborhood.What is the closest meaning of the underlined word “proportions” ?
| A．Shares. | B．Degrees. |

How can you lose weight?

| B．Control your diet strictly. |
| C．Exercise as well as go on a diet. |
| D．Read more articles about losing weight. |
Why did the First Lady start a movement in public schools?
| A．To raise people’s health consciousness. |
| B．To help people realize the importance of dieting. |
| C．To forbid sugary soft drinks. |
| D．To control the dietary supplying. |
What does the fifth paragraph mainly talk about?
| A．What makes the proper diet. |
| B．Vegetables are good for health. |
| C．Drink more water and less sugary drinks. |
| D．Dairy products will helps losing weight. |
According to the last paragraph ,what can you do if you can’t jog to work out?

Small endangered animals are often hard to find in their natural habitats, making it difficult for scientists to monitor them and develop conservation plans. But new technologies can help. Australian researchers have equipped flying drones with infrared cameras so they can spot koalas hiding high in trees.
Koalas spend most of their lives in eucalyptus trees, whose leaves are their favorite food. Since the leaves are low on calories and nutritional content, koalas are not very active - they sleep up to 20 hours a day. Curled-up in high branches, they are not easy to spot from the ground, and they have few natural predators. The greatest threat to this iconic symbol of Australia is logging.
“Every single tree in Australia right now, needs to be protected and unless that happens I can promise you the koala is going to go to extinction,” said Deborah Tabart, Australian Koala Foundation.
Scientists studying koalas say one of the keys for saving the animals is to know where they live and how many of them are left.
Using drones fitted with infrared cameras to conduct a census was an untested concept. Queensland Institute of Technology technician, Gavin Broadbent, said they were skeptical at first. “But when we saw the images come through, we saw the koalas were very distinct compared to the trees and the environment. So we thought, yes this is absolutely a proof of concept that could work,” he said.
The images beamed back to a computer clearly show the animal’s position, even from a distance far enough away not to disturb its sleep.
“We have tested at 20 meters and 80 meters. At 20 meters we get really good resolution,” stated Felipe Gonzalez, project leader.
The remotely controlled camera pivots and swivels, so scientists can scan the trees from all angles, picking out koalas even in the most dense areas, not visible to researchers on foot.
“So this will drastically reduce the manpower," said Amber Gillett, a veterinarian with the Australia Zoo. "Will greatly increase the area that can be covered to survey koalas and in areas where people may not be able to walk through because of dense undergrowth.”
Scientists say it is now clear that drones with infrared cameras can be used for spotting, and perhaps saving, other animals in the wild.What is an important factor in protecting the animals according to the passage?

| B．They can help reduce the manpower. |
| C．They can scan the trees from all angles. |
| D．They can send the images back to a computer. |

“Just take it easy.” “Don’t be nervous.” “You’re more likely to die in a car wreck on the way to the airport than you are in a plane crash.” These are just some words given to people with a fear of flying. But as Tom Cruise, playing Lt. Daniel Kaffee in the movie A Few Good Men, said, “I get sick when I fly because I’m afraid of crashing into a large mountain. I don’t think Daniel will help.”
But there’s a new application that just may. Today, the VALK Foundation, a Dutch group that’s a partnership between KLM Royal Dutch Airlines and the University of Leiden, launches the app in the US. The VALK Foundation was one of the first centers for research and fear-of-flying treatment in the world and is the organizer of three world conferences on fear of flying.
The foundation said the app, called Flight App VALK, is the first scientifically-developed, web-based treatment for people who suffer from mild to moderate fear of flying.
“The fear of flying application we have created aims to transfer all of the knowledge we have developed through our program into a mobile application that will help ease travelers’ fears,” said Dr. Lucas van Gerwen, director of the VALK Foundation. Dr. van Gerwen is also a psychologist and professional pilot with more than 30 years experience.
The foundation said up to 30% of adults are fearful fliers. The Flight App is designed to help relax passengers before and during flights by educating users about flight safety and turbulence. It explains the sounds and sensations they can expect during departure, flight and landing. And, if a passenger’s flight stress reaches a panic level, they press a special panic button which provides audio and written information to help decrease stress levels. Most importantly, the Flight App can be used during the flight in the airplane mode. Once downloaded, the program does not require Internet connection in the air.Why are the words at the beginning of the passage given to people?

As smartphones and other handheld devices are becoming more affordable, doctors say children who spend long hours playing video games are increasingly showing signs of postural deformities. Physical therapists warn that long-term consequences may be severe.
Owaish Batliwala, 10, from Mumbai, India, admitted spending three to four hours each day playing games on his tablet computer. When he started complaining about a neck pain, his mother Mehzabin became concerned.
“My son got a problem in his neck around June, July. The pain gradually spread to his hand and his back, this was the problem,” she explained. “He plays for hours on the iPad and mobile phone. He plays regularly for at least for two-three hours, that's what caused the problem.”
Physical therapist Sadia Vanjara said the number of young children with chronic pain in upper extremities is on the rise.
“They are not ageing, they haven't had an accident, their age is like, under 10, they are not complaining, the blood reports are fine, their X-rays are fine, their MRI's are fine, then where is the culprit? And that is the very common thing that is happening amongst all children and that is smart phones and the gadgets,” Vanjara said.
There are more smartphone users in India than anywhere else in the world, except for China. Networking technology giant Cisco estimates their numbers will increase from 140 million today to 651 million by the end of the decade.
Vanjara said the best remedies for already-existing pain are daily exercises.
With correct posture, pain can be prevented, so Vanjara also teaches children how to hold their gadgets correctly.
“If you hold the phone up in front of you, your head will not be bent down to look at it and so your neck won’t get strained,” she said.
With the number of smartphones and other handheld devices constantly on the rise, Vanjara predicts we will see not only physical but also psychological and emotional ailments stemming from their excessive use.Why did Mehzabin become concerned?
| A．Her son was addicted to playing computer games. |

In ancient Egypt, the pharaoh（法老）treated the poor message runner like a prince when he arrived at the palace, if he brought good news. However, if the exhausted runner had the misfortune to bring the pharaoh unhappy news, his head was cut off.
Shades of that spirit spread over today’s conversations. Once a friend and I packed up some peanut butter and sandwiches for an outing. As we walked light-heartedly out the door, picnic basket in hand, a smiling neighbor looked up at the sky and said, ”Oh boy, bad day for a picnic. The weatherman says it’s going to rain.”I wanted to strike him on the face with the peanut butter and sandwiches. Not for his stupid weather report, for his smile.
Several months ago I was racing to catch a bus. As I breathlessly put my handful of cash across the Grey hound counter, the sales agent said with a broad smile ,”Oh that bus left five minutes ago.”Dreams of head-cutting!
It’s not the news that makes someone angry. It’s the unsympathetic attitude with which it’s delivered. Everyone must give bad news from time to time, and winning professionals do it with the proper attitude. A doctor advising a patient that she needs an operation does it in a caring way. A boss informing an employee he didn’t get the job takes on a sympathetic tone. Big winners know, when delivering any bad news, they should share the feeling of the receiver.
Unfortunately, many people are not aware of this. When you’re tired from a long flight, has a hotel clerk cheerfully said that your room isn’t ready yet? When you had your heart set on the toast beef, has your waiter mainly told you that he just served the last piece? It makes you as traveler or dinner want to land your fist right on their unsympathetic faces.
Had my neighbor told me of the upcoming rainstorm with sympathy, I would have appreciated his warming .Had the Greyhound salesclerk sympathetically informed me that my bus had already left, I probably would have said, ” Oh, that’s all right I’ll catch the next one.” Big winners, when they bear bad news ,deliver bombs with the emotion the bombarded（被轰炸的）person is sure to have.Why did the writer tell the story of the pharaoh in paragraph 1?
| A．To make a comparison | B．To introduce a topic |
| C．To give an example | D．To offer an argument |
What does “Dreams of head-cutting!” in Paragraph3 mean?
| A．The writer was mad at the sales agent |
| B．The writer was reminded of the cruel pharaoh |
| C．The writer wished that the sales agent would have had dreams |
| D．The writer dreamed of cutting the sales agent’s head that night. |
Why was the writer angry with his neighbor?
| A．Because he couldn’t have a picnic. |
| B．Because the weather was bad. |
| C．Because he hated smiles. |
| D．Because of his unsympathetic attitude. |
What can we learn from the passage?
| A．Learning ancient traditions can be useful. |
| B．Delivering bad news properly is important in communication. |
| C．Helping others sincerely is the key to business success. |
| D．Receiving bad news requires great courage. |
