Watching television makes it easier for toddlers（学走路的孩子）to kick and scream, according to a U.S. study. Children under two should not watch any TV. The longer they sit in front of the box, the worse their behavior becomes.
Just having the TV on in the background, even if the child wasn’t watching it, was also connected to troublemaking behavior although the relationship wasn’t as strong, said the researchers.
“Parents should be smart about TV use,” researcher Jennifer Manganello from the University at Albany, New York, said.
“They should limit the time that children use TV, pay attention to the content of TV programs, and consider how TV is used throughout the home.”
The study looked at 3,128 women from 20 U.S. cities who had a child between 2005 and 2008.
While there was some diversity（差异）of education among the women, one-third hadn’t graduated from high school.
Two-thirds of the mothers said their three-year-old watched more than two hours of TV a day, and the average（平均的）viewing time for children was around three hours. On average, the TV was on for about five additional hours on a common day.
After accounting for factors（因素）such as living in a violent neighborhood, scientists also found watching TV was strongly connected to behavior such as hitting others, having angry moods, being disobedient（不服从的）, and screaming a lot.
The researchers thought that children may see violence on TV, and spend less time on positive development tasks such as reading or playing.
The American Academy of Paediatrics suggests no TV at all for children at two and younger, and two hours a day or less for older kids.what is the main idea of the passage?
| A．Children should choose positive programs. |
| B．Children should keep away from TV. |
| C．Watching TV can make children violent. |
| D．Parents should watch less TV. |
what do we know from Paragraph 2?
| A．Children can watch good programs. |
| B．Children will be affected as long as the TV is on. |
| C．It’s OK that the TV is on if children don’t watch it. |
| D．Children’s troublemaking behavior is mainly caused by watching TV. |
what can be learned about the study between 2005~2008 from the passage?
| A．The TV was on for about three hours. |
| B．The women studied have different jobs. |
| C．The study included men and women. |
| D．Most women allowed their child to watch TV. |
Children who spend much time watching TV will ________.
| A．not be hit by others |

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. |

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________.

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. |

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. |
