In a national spelling contest in America，an 11-year-old girl was asked to spell a certain word. But with her   36  voice the judges were not sure whether she spelled the word with the letter A or E. They talked it over and   37  decided to simply ask her what she had said. By now, the girl knew she had   38  the word. But instead of lying，she told the truth that she had said the   39  letter—so she lost the contest.
As the girl walked off the   40 ，the entire audience stood to their feet clapping to applaud her   41 . Later，dozens of newspaper reporters wrote about this 11-year-old girl’s honesty，even when it   42  her the contest. But the fact is that she   43  the biggest contest that day: the contest of her   44 .
Probably the biggest test of our character and honesty is that we would do if we knew we would never get   45 . This young girl could easily have   46  and nobody would have known it but herself. But that’s just it: She would know she did wrong. It’s been said, “If you   47 , you make yourself cheap.” This young girl was strong and smart enough to prize her own   48  and character more than the prize from a spelling   49 . Her respect for herself was more important than any    50  others might give her for winning a contest. She knew she would have to live with herself and the   51  she made in that moment will have long-lasting influence.
It’s so true that the choices you make today   52  what you are tomorrow. Our children will   53  our behavior much more than our advice. So if we want them to   54  to be honest，we must show them the way by being honest ourselves. Remember，our kids are   55  what we do and how we live even when we don’t think they see or know.

Do you enjoy reading? Do you read newspapers or magazines? Chances are, if you do any of these activities, your pre-school child is on his way to becoming a reader.
The process of learning to read is complex, and one of the most important things to know is that parents can help their children learn to read. As children have conversations with adults, they hear both new and familiar words and their vocabulary grows.
There are many opportunities for adults and children to talk together, such as when riding in the car or in a bus, doing housework like fixing dinner, or bathing and getting ready for bed. A major part of conversation is listening. When children talk, adults listen and respond. Then children listen and respond, and so the flow of conversation happens.
Have you watched you pre-school child pretend to read to his younger sisters or brothers? Have you read his favorite story over and over? These experiences tell children that reading is fun. And when things are fun and they are repeated, your child will see letters. He begins to connect them to familiar words, especially the letters that make up his name. A natural next step for him to take is to write the letters.
When children see parents make a grocery list, they want to use a pencil and paper to make their own list. To encourage these beginning writing activities, have pencils, markers, crayons and scrap paper within your children’s reach.
The more children get connected with talking, listening, reading and writing, the easier it is for them to become active readers. While you as a parent have a big influence on these early behaviors, it is important to remember that opportunities for literacy experiences happen when you and your child share in the basic routines（日常生活）of everyday life.

A new study suggests that the roundtheclock availability that cell phones have brought to people's lives may take a toll on family life. The study，which followed more than 1,300 adults over 2 years, found that those who consistently used a mobile phone throughout the study period were more likely to report negative “spillover” between work and home life—and，in turn，less satisfaction with their family life.
Spillover essentially(本质上)means that the line between work and home begins to become unclear. Work life may invade home life when a parent is taking jobrelated calls at home，for instance—or family issues may start to take up work time. For example，a child may call mum at work，telling her “microwave exploded”，explained Noelle Chesley，an assistant professor of sociology at the University of WisconsinMilwaukee and the author of the study. The problem with cell phones seems to be that they are allowing for even more spillover between work and home.
This may be especially true for working women，the study found. Among men，consistent use of mobile phones seemed to allow more work issues to creep (潜入)into family time. But for women，the spillover tended to go in both directions. Being “connected” meant that work cut into home time，and family issues came into work life.
Cell phones seem to be opening more lines for stressful exchanges among family members. But there may be ways to control the spillover，according to Chesley. Employers, she said，could look at their policies on contacting employees after hours to make sure their expectations are “reasonable”．For their part，employees could decide that cell phones go off during family time, Chesley said.
【小题1】What does the underlined phrase “take a toll on” probably mean in Paragraph 1?

【小题2】According to Chesley，what is the best solution to the problem caused by cell phones?

A．Separate work hours from family time.

B．Refuse to use cell phones.

C．Ignore coming calls during family time.

D．Encourage women to stay at home.

【小题3】We can learn from the passage that ________.

A．cell phones affect men as much as women

B．cell phones seem to be convenient to families
