Example Input: Article: The round-the-clock availability that cell phones have brought to people's lives may be _ amily life, a new study suggests. The study, which followed more than 1300 adults over 2 years, found that those who consistently used a mobile phone through out 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(,) actually means that the line between work and home began to become unclear. Work life may invade home life--when a parent is taking job-related calls at home, for instance--or family issues may start to take up work time. For example, a child may call Mom at work, telling her "the microwave exploded", explained Noelle Chesley, an assistant professor of society at the University of Wisconsin Milwaukee and the author of the study. The problem with cell phones seems to be they are allowing for ever 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 not to allow more work issues to creep into family time. But for women, the spillover tended to go in both directions--being "connected" means that work cuts into home time, and family issues come into work life. Cell phones seem to be opening more lines for stressful exchange among family members. But there may be ways to control the spillover, according to Chesley. Employers, she said, should look at their policies on contacting employees after working hours to make sure their expectations are "reasonable". For their part, employees can decide that cell phones go off during family time, Chesley said.

Example Input: Article: Most Chinese people these days know what it is like to have an "English teacher", since almost all pupils study English from their third year. Usually that first English teacher will be a young and lovely lady in primary school. But my first English teacher is _ . Looking back, I can see that, when I was only a little girl, he created an English environment by providing me with flashcards,fun English- language toys and even dolls which can sing English songs! My interest in English had certainly been awakened when I began to learn English at school. Just imagine, he went a step further and asked me to learn New Concept English by myself! I was puzzled and even angry. I could not understand why a father could be so strict with his little girl. All the same, he never gave up and he gently insisted that I follow through with his idea. At first, I read stories with tears and I actually hated them because they were too difficult for me. In the end, I came to love the funny stories and, to be honest, my father was always there with a helping hand. I am sure that my English would never have got so far without his support. And that's why my father is not only my first English teacher but also my lifelong teacher. He is one who awoke my interest, and who gave me much confidence .
