Scientists at the University of Pittsburgh, USA, wanted to know why some people are 39 likely to fall than others.
The researchers found that 40 means more than planting your feet on the ground and standing tall. Your brain 41 your sense of balance with information from your eyes and inner ears and the 42 from your feet and legs. If something goes wrong with any of these, you’re 43 to fall. People 44 to fall more often as they grow older because their senses are slower.
State of mind is important too. The research shows that when people know they’re walking on a slippery surface, they 45 their pace and walk with flatter feet. As a result, they fall less often.
“We actually 46 people slip and fall,” researcher Mark Redfern said. People of different ages fall on 47 in his lab. Cameras 48 their falls and a computer analyzes the information. Scientists then can 49 people who fall often how to be more watchful.
“If they get 50 to a lifelike but controlled environment, people can 51 learn to handle the 52 thing,” Redfern said.
Falls happen to everyone sometimes. 53 you see someone fall, think about why and offer a helping 54 . This person’s painful experience may 55 you from falling at the same place.

举一反三
In many ways, the earliest periods of photography are the most satisfying. Learning to use the controls is easy and comes quickly, and you can measure the results in terms of sharp and correctly developed pictures. Once you have mastered that, you can start on the second step of your photographic work. Using these basic skills in the wide variety of situations to give the pictures you want, noticing what you see through the viewfinder and turning that into the most effective picture becomes totally interesting.
All good photographs have one thing in common: there is no doubt what the subject of the picture is meant to be. Every photographer must use those same standards to his or her work, not only to finished results but to the subject before he or she takes it. Always work out quite clearly what the subject of the picture is to be and why you are taking the picture. For example, "I am going to take a picture of this street to show the different styles and ages of the buildings and that people have been living, working and shopping in them since time began." By doing this you have a better idea of what to include in the picture and what to leave out. How often have you been shown photographs taken by people away on a trip somewhere? The judgment is always similar, something about "the car park is out of the picture to the left", or "you can"t quite see from this picture but if you go up the street". The photographs are usually collections of buildings, people, parked cars, possibly a distant look of an ancient church, and best of all, a figure which you are told is Aunt Henrietta, disappearing in the middle distance. When photographers show you their pictures, they have a clear idea of what they want to bring to your attention, but it often does not appear in the picture. If they had given just a little of their time to think about their future judgment before taking the picture, then the picture would relate its own story. Good pictures can show their subjects quickly and easily.
64. What does the author mean by saying "in many ways, the earliest periods of photography are the most satisfying"?
A. The skills of photography are not as satisfactory nowadays as before.
B. The earliest pictures were the best pictures people have ever taken.
C. The present-day photography depends more on technology than on art.
D. Learning to produce a sharp and correctly developed picture is only the first step in photography and is easily learned.
65. What will it bring you if you decide the purpose of the photograph in advance?
A. It will allow you to leave out unnecessary material.
B. It will allow you to stand in the best place.
C. It will help you to vary the subjects of your pictures.
D. It means you will waste less time.
66. Many photographers fail because ______.
A. their pictures include both buildings and people
B. everything is not clear in their pictures
C. the subjects of their pictures are not obvious
D. the explanation given for their pictures is mistaken
67. What book is this passage most likely taken from?
A. A book on photography for news reporters. B. A book on how to photograph people.
C. A book on choosing the right camera. D. A book on improving photographic techniques.
Well, in fact it isn’t quite as simple as that. Yes , it is true that being the boss has its satisfactions and that you can arrange your working hours freely if you own your own small business . But in those early years of starting your own business, you shouldn’t think of a free day, not to mention flying off for a month’s vacation. It is not unusual for new business owners to work seventy or eighty hours a week , and if there is a day off , that day might need to be devoted to accounting (算账).
But this negative picture doesn’t destroy the beautiful hopes. The possibility of getting something wonderful in return—both material and mental—continues to drive that large number of people who start up small businesses each year in the United States.
小题1:From the first paragraph, we know that everybody hopes ________ .
A.to rule others | B.to be his or her own boss |
C.to get a time clock | D.to be free from work |
A.work more than 10 hours a day | B.devote himself to accounting |
C.fly to some places in the world | D.have a day off in a week |
A.a terrible experience | B.a poor picture |
C.limited freedom | D.unpleasant situations |
A.people love beautiful things by nature |
B.people have a strong desire to seek personal gains |
C.small businesses make big money each year in the US |
D.small businesses have advantages over big companies |
Sleep scientists have long known that getting a good night’s sleep is very important. It helps kids be able to do their best during the day.
A recent study shows that sleep helps improve problem-solving skills and creative(创造性的) thinking. For the study, two groups of students answered a math problem. The group that slept for eight hours solved the problem correctly more often than the group that did not get enough sleep.
While you sleep at night, your brain is busy doing its “homework”. It sorts out(整理) all the information that you get in the day. Getting enough sleep each night can improve your thinking ability. That will surely help you do your best at school. Experts say that, in return, can lead to better grades.
小题1:The underlined word grumpy in the first paragraph means_______.
A.excited and happy | B.active and creative |
C.impatient and angry | D.bored and weak |
A.Sleep to Success | B.A Recent Study |
C.Do Sleep Well | D.The More Sleep, the Better |
When you see an opportunity, take it. You might not get it back. Never let an opportunity pass. And if it is too hard, remember that in the middle of every difficulty lies an opportunity.
Remember, you cannot choose how you" re going to die, or when. You can only decide how you" re going to live. Study as if you were going to live forever; live as if you were going to die tomorrow. Don" t just think of the present, but also think of your future. Your future is yet another chapter in your life and another way to live it.
Every single living thing has a purpose in life. "The purpose of life is a life of purpose," said Robert Byme.
Learn to use time wisely, take opportunities, and enjoy life. We can discover the meaning of life in three different ways: (1) by doing a deed; (2) by experiencing a value; (3) by suffering life. So, what are you buying with yours?
小题1:The underlined part suggests that___________.

C.an argument that time is the most important thing in life |
D.a description of an important class |
Perceiving goes on in our minds. Of the three people who look out the window, one may say that he sees a policeman giving a motorist a ticket. Another may say that he sees a rush-hour traffic jam at the intersection. The third may tell you that he sees a woman trying to cross the street with four children in tow. For perception(感知) is the minds’ interpretation of what the senses — in this case our eyes — tell us.
Many psychologists(心理学家)today are working to try to determine just how a person experiences or perceives the world around him. Using a scientific approach, these psychologists set up experiments in which they can control all of the factors. By measuring and charting the results of many experiments, they are trying to find out what makes different people perceive totally different things about the same scene.
小题1:Perceiving is an action that takes place ______.
A.in our eyes | B.only when we think very hard about something |
C.only under the direction of a psychologist | D.in every person’s mind |
A.they see different things | B.they can not agree about things |
C.some have better eyesight | D.none of these |
A.setting up many experiments | B.asking each other what they see |
C.looking out of windows | D.studying people’s eyes |
A.How We See | B.Learning About Our Minds Through Science |
C.What Psychologists Perceive | D.How To Become An Experimental Psychologist |
