The bedroom door opened and a light went on, signaling an end to nap time．The toddle（初学走路的婴儿）, sleepy-eyed, clambered to a swinging stand in his crib．He smiled, reached out to his father, and uttered what is fast becoming the cry of his generation: "iPhone!"
Just as adults have a hard time putting down their iPhones, so the device is now the Toy of Choice for many 1-, 2- and 3-year-olds．The phenomenon is attracting the attention and concern of some childhood development specialists．
Natasha Sykes, a mother of two in Atlanta, remembers the first time her daughter, Kelsey, now 3 but then barely 2 years old, held her husband's iPhone．"She pressed the button and it lit up．I just remember her eyes．It was like 'Whoa!' "The parents were charmed by their daughter's fascination．But then, said Ms．Sykes （herself a Black Berry user）, "She got serious about the phone．" Kelsey would ask for it．Then she'd cry for it．"It was like she'd always want the phone," Ms．Sykes said．
Apple, the iPhone's designer and manufacturer, has built its success on machines so user-friendly that even technologically blinded adults can figure out how to work them, so it makes sense that sophisticated children would follow．Tap a picture on the screen and something happens．What could be more fun?
The sleepy-eyed toddler who called for the iPhone is one of hundreds of iPhone-loving toddlers whose parents are often proud of their offspring's ability to slide fat fingers across the gadget's screen and pull up photographs of their choice．
Many iPhone apps on the market are aimed directly at preschoolers, many of them labeled "educational," such as Toddler Teasers: Shapes, which asks the child to tap a circle or square or triangle; and Pocket Zoo, which streams live video of animals at zoos around the world．
Along with fears about dropping and damage, however, many parents sharing iPhones with their young ones feel guilty．They wonder whether it is indeed an educational tool, or a passive amusement like television．The American Academy of Pediatrics is continually reassessing its guidelines to address new forms of "screen time．" Dr．Gwenn Schurgin O'Keeffe, a member of the academy's council, said, "We always try to throw in the latest technology, but the cellphone industry is becoming so complex that we always come back to the table and wonder- Should we have a specific guideline for them?"
Tovah P. Klein, the director of a research center for Toddler Development worries that fixation on the iPhone screen every time a child is out with parents will limit the child's ability to experience the wider world.
As with TV in earlier generations, the world is increasingly divided into those parents who do allow iPhone use and those who don't. A recent post on UrbanBaby.com, asked if anyone had found that their child was more interested in playing with their iPhone than with real toys. The Don't mothers said on the Website: "We don't let our toddler touch our iPhones ... it takes away from creative play." "Please ... just say no. It is not too hard to distract a toddler with, say ... a book."
Kathy Hirsh-Pasek, a psychology professor who specializes in early language development, sides with the Don'ts. Research shows that children learn best through activities that help them adapt to the particular situation at hand and interacting with a screen doesn't qualify, she said.
Still, Dr. Hirsh-Pasek, struck on a recent visit to New York City by how many parents were handing over their iPhones to their little children in the subway, said she understands the impulse (冲动). "This is a magical phone," she said. "I must admit I'm addicted to this phone."The first paragraph in the passage intends to ______.

People born in winter are more likely to suffer mental health disorders, according to a recent study carried out by researchers at Vanderbilt University in Tennessee.
Researchers raised baby mice from birth to weaning (断奶) in either “summer” light cycles of 16 hours of light and 8 hours of dark or “winter” cycles of 8 hours of light and 16 hours of dark. A third group experienced 12 hours of light and 12 hours of dark a day.
Then half the winter mice stayed in a winter cycle, while half switched to a summer schedule. The summer mice were similarly split. The mice raised in equal periods of light and dark were split into three groups, one of which stayed on the 12hour schedule, one of which joined the winter group, and one of which joined the summer group.
After 28 days, it turns out the summerborn mice behaved the same whether they stayed on the summer cycle or switched to winter. But among the winterborn mice, those stayed in winter kept their previous schedule, while those that switched to summer stayed active for an extra hour and a half, which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions in their biological clocks.
The finding is the first of its kind in mammals, and it could explain why people born in winter are at higher risk for mental health disorders including bipolar depression, schizophrenia and seasonal affective disorder.
“We know that the biological clock regulates mood in humans，”said study researcher McMahon. “If the mechanism (机制) similar to the one that we found in mice operates in humans, then it could not only have an effect on a number of behavioral disorders, but also have a more general effect on personality.”How many groups of mice are there finally in all in the experiment?
| A．Seven. | B．Six. | C．Five. | D．Four. |
What's the main idea of the text?
| A．The biological clock regulates mood in humans. |
| B．People born in winter are at higher risk for physical health disorders. |
| C．The length of light will influence the behavior of the mice. |
| D．Being born in winter has a negative effect on people's mental health. |
The underlined word “split”(Paragraph 3) can be replaced by ________.
| A．ended | B．divided | C．hit | D．torn |
Who is the appropriate reader of the passage?
| A．A jobhunter. |
| B．A student in the university. |
| C．A newlymarried couple. |
| D．An experienced dentist. |

Self-confidence is an attitude which allows individuals to have positive yet realistic views of themselves and their situations. Self-confident people trust their own abilities, have a general sense of control in their lives, and believe that，within reason, they will be able to do what they wish, plan, and expect. Having self-confidence does not mean that individuals will be able to do everything. Self-confident people have expectations that are realistic. Even when some of their expectations are not met，they continue to be positive and to accept themselves.
People who are not self-confident depend too much on the approval of others in order to feel good about themselves. They tend to avoid taking risks because they fear failure. They generally do not expect to be successful. They often put themselves down and tend to ignore compliments（赞美）paid to them By contrast，self-confident people are willing to risk the disapproval of others because they generally trust their own abilities. They tend to accept themselves；they don't feel they have to conform in order to be accepted.
Many factors affect the development of self-confidence. Parents' attitudes are crucial(关键性的) to children's feelings about themselves，particularly in children's early years. When parents provide acceptance, children receive a solid foundation for good feelings about themselves. If one or both parents are much to critical or demanding, or if they are overprotective and discourage children's moves toward independence, children may come to believe they are unqualified or inadequate.
Surprisingly, lack of self-confidence is not necessarily related to lack of ability. Instead it is often the result of focusing too much on the unrealistic expectations or standards of others，especially parents and society. Friends' influences can be as powerful or more powerful than those of parents and society in shaping feelings of one's self. Students in their college years reexamine values and develop their own identities and thus are particularly sensitive to the influence of friends.Paragraph 1 mainly talks about________.
| A．the sources of self-confidence |

Arriving in Sydney on his own from India, my husband, Rashid, stayed in a hotel for a short time while looking for a house for me and our children.
During the first week of his stay, he went out one day to do some shopping. He came back in the late afternoon to discover that his suitcase was gone. He was extremely worried as the suitcase had all his important papers, including his passport（护照）.
He reported the case to the police and then sat there, lost and lonely in strange city, thinking of the terrible troubles of getting all the paperwork organized again from a distant country while trying to settle down in a new one.
Late in the evening, the phone rang. It was a stranger. He was trying to pronounce my husband’s name and was asking him a lot of questions. Then he said they had found a pile of papers in their trash can（垃圾桶）that had been left out on the footpath.
My husband rushed to their home to find a kind family holding all his papers and documents. Their young daughter had gone to the trash can and found a pile of unfamiliar papers. Her parents had carefully sorted them out, although they had found mainly foreign addresses on most of the documents. At last they had seen a half-written letter in the pile in which my husband had given his new telephone number to a friend.

It was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.
The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries（食品杂货），saving us from having to walk long distances from where we live.
I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.
People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity（人性）as a whole. And it has influenced us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting. Why was the bike so important to the couple?
| A．The man’s job was bike racing. |
| B．It was their only possession. |
| C．It was a nice Kona 18 speed. |
| D．They used it for work and daily life. |
We can infer from the text that ____________.
| A．the couple worked 60 hours a week. |
| B．people were busy before Christmas |
| C．the stranger return the bike |
| D．life was hard for the young family. |
How did people get to know the couple’s problem?
| A．From radio broadcasts. | B．From a newspaper. |
| C．From TV news. | D．From a stranger. |
What do the couple learn from their experience?
| A．Strangers are usually of little help. |
| B．One should take care of their bike. |
| C．News reports make people famous. |
| D．An act of kindness can mean a lot. |
