Using a computer or smartphone at night can cause us to pile on the pounds，new research has revealed．
The study found a link between blue light exposure(blue light is produced by smartphones and computers)and increased hunger．It found that exposure to blue light increases hunger levels for several hours and even increases hunger levels after eating a meal．Blue light exposure has also already been shown to cause decreased sleepiness in the evening，increasing the risk of sleeplessness．
The leading researcher，Ivy Cheung，from Northwestern University in Chicago，said，“A single three-hour exposure to blue-enriched light in the evening greatly affected hunger and metabolism(新陈代谢)．These results are important because they suggest that controlling environmental light exposure for humans may represent a novel approach of influencing food intake patterns and metabolism．”
The study group consisted of 10 healthy adults with regular sleep and eating schedules. They completed a four-day trial under dim(昏暗的)light conditions，which involved exposure to less than 20 lux(勒克斯，照明单位)during 16 hours awake and less than 3 lux during eight hours of sleep．On the third day they were exposed to three hours of 260 lux，blue-enriched light starting10.5 hours after waking up．and the effects were compared with dim light exposure.
Ivy Cheung said more research is needed to determine the functions involved in the relationship between light exposure，hunger and metabolism．What is Paragraph 2 mainly about?
| A．How blue light exposure affects hunger． |
| B．Why blue light exposure influences sleepiness． |
| C．What is the link between blue light exposure，hunger and sleepiness． |
| D．Who has found the effects of blue light exposure on hunger and sleepiness． |
The underlined word“novel”in the third paragraph probably means“___________”.
| A．unusual | B．unforgettable |
| C．temporary | D．controversial |
What can we learn from the passage?
| A．Blue light exposure can make us lose weight at night． |
| B．Blue light exposure has no effect on sleeplessness． |
| C．The researchers drew their conclusion by comparison． |
| D．Ivy Cheung has found the relationship between light exposure and hunger． |
Where would you be most likely to find the passage?
| A．On a notice board． | B．In a health magazine． |
| C．On a business website． | D．In a college newspaper． |
Play is the basic business of childhood, and in recent years research has shown the great importance of play in the development of a human being. From earliest infancy (婴儿), every child needs opportunity and right materials for play, and the main tools of play are toys. The main function of toys is to suggest, encourage and play. To succeed in this, they must be good toys, which children will play with often, and will come back again and again. Therefore, it is important to choose suitable toys for different stages of a child’s development.
In recent years research on infant development has shown that the standard a child is likely to reach, within the range of his inherited abilities, is largely determined in the first three years of his life. So a baby’s ability to benefit from the right play materials should not be underestimated. A baby who is encouraged, talked to and shown things and played with, has the best chance of growing up successfully.
In the next stage, from three to five years old, curiosity knows no bounds. Every type of suitable toys should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability: Bricks and jigsaws and construction toys; painting, scribbling and making things; sand and water play; toys for imaginative and pretending play—the first social games for learning to play and get on with others.
But at the third stage of play development—from five to seven or eight years old— the child is at school. But for a few more years play is still the best way of learning, at home or at school. It is easier to see which type of toys the child most enjoys.
Until the age of seven or eight, play and work mean much the same to a child. But once reading has been mastered, then books become the main source of learning. Toys are still interesting and valuable, which lead up to new hobbies, but their significance has changed — to a child of nine or ten years old, toys and games mean, as to adults, relaxation and fun.

“Can I see my baby?” asked the happy new mother. The bundle （婴儿包）was placed in her arms and when she moved the fold of cloth to look upon his tiny face, she gasped—the baby had been born without ears. Time, however, proved that the baby’s hearing was perfect except his appearance.
One day when he rushed home from school and threw himself into his mother’s arms, he cried out bitterly, “A boy, a big boy … called me — a f-…freak.” She sighed, knowing that his life was to be endless of heartbreaks.
He grew up, handsome for his misfortune. A favorite with his fellow students, he might have been class president, but for that. He developed a gift for literature and music.
The boy’s father had a talk with the family doctor. Could nothing be done? “I believe we could graft（移植）on a pair of outer ears, if they could be donated,” the doctor decided. So the search began for a person who would make such a sacrifice for a young man. Two years went by. Then, “You’re going to the hospital, son. Mother and I have someone who will donate the ears you need. But it’s a secret.” said the father.
The operation was a brilliant success. His talents blossomed into genius. School and college became a series of successes. Later he married and entered the diplomatic service. “But I must know!” he urged his father. “Who gave so much for me? I could never do enough for him.” “I do not believe you could,” said the father, “but the agreement was that you are not to know … not yet.” The years kept the secret, but the day did come … one of the darkest days that ever pass through a son. He stood with his father over his mother’s casket（棺材）. Slowly and tenderly, the father stretched forth a hand and raised the thick, reddish-brown hair to let out the secret.

B. It is up to parents to help their children heart and soul.
C. True beauty lies only in the heart not in appearance.
D. It is a virtue（美德）for young generations to learn to be grateful.
Habits are a funny thing. We reach for them mindlessly, setting our brains on auto-pilot and relaxing into the unconscious comfort of familiar routine.“Not choice, but habit rules the unreflecting creatures,”William Wordsworth said in the 19th century. In the ever-changing 21st century, even the word“habit”carries a negative meaning.
So it seems contradictory to talk about habits in the same context as innovation (创新). But brain researchers have discovered that when we consciously develop new habits, we create parallel paths, and even entirely new brain cells, that can jump our trains of thought onto new, innovative tracks.
Rather than dismissing ourselves as unchangeable creatures of habit, we can instead direct our own change by consciously developing new habits. In fact, the more new things we try, the more creative we become.
But don’t bother trying to kill off old habits; once those ruts of procedure are worn into the brain, they’re there to stay. Instead, the new habits we deliberately press into ourselves create parallel pathways that can bypass those old roads.
“The first thing needed for innovation is attraction to wonder,”says Dawna Markova, author of The Open Mind.“But we are taught instead to‘decide’, just as our president calls himself‘the Decider’．”She adds, however, that“to decide is to kill off all possibilities but one. A good innovational thinker is always exploring the many other possibilities.”
“All of us work through problems in ways of which we’re unaware,”she says. Researchers in the late 1960s discovered that humans are born with the ability to approach challenges in four primary ways: analytically, procedurally, collaboratively (合作地) and innovatively. At the end of adolescence, however, the brain shuts down half of that ability, preserving only those ways of thought that have seemed most valuable during the first decade or so of life.
The current emphasis on standardized testing highlights analysis and procedure, meaning that few of us use our innovative and collaborative ways of thought.“This breaks the major rule in the American belief system—that anyone can do anything,”explains M. J. Ryan, author of the 2006 book This Year I Will…and Ms. Markova’s business partner.“That’s a lie that we have preserved, and it fosters commonness. Knowing what you’re good at and doing even more of it creates excellence.”This is where
developing new habits comes in.
67．Brain researchers have discovered that__________.
A．the forming 
of new habits can be guided

A．Decision makes no sense in choices.
B．Curiosity makes creative minds active.
C．Creative ideas are born of a relaxing mind.
D．Formation of innovation comes from fantastic ideas.
70．The purpose of the author writing this article is to persuade us____________.

Apparently，we are safe neither at home nor in the business office．We use water in both places，but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects．These chemicals can cause potential harm through drinkin
g and in seemingly harmless activities as cleaning one’s house．They are released(set free)from water by daily actions like water running out 
of tap，spraying from garden pipes，or splashing in dishwashers and washing machines．As the water is moving．these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.
Does this mean we should stop bathing?
No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that“new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.
These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.
We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up ), the factory work environment ( an endless list of potentially dangerous substances ), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that“there is no place like home.”
64．What is the main idea of the first paragraph?
A．The air we breathe in is harmful.
B．The water in everyday use is unsafe.
C．Chemicals are added to the drinking water.
D．Chemicals are released in the running water.
65．In Paragraph 2, the underlined sentence means that__________
A．bathing should be done with caution
B．homes and offices should be aired often
C．any pollution should be taken into consideration
D．we should prevent any pollution from doing harm to us
66．What is the purpose of the passage?
A．To call on us to guard our water.
B．To show us that no place is like home.
C．To make us aware of the pollution around us.
D．To argue that neither homes nor offices are safe.
