[EX Q]: 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.

[EX Q]: Article: One Halloween a little boy and his friend went out for a fun night of trick-or-treating. At first everything was great. They were getting lots of candy as they went from house to house, but then they saw a house which they hadn't been to before. It was a very spooky house. Being young and brave, they decided to go up to the door and knock. After all, scary houses might have the best candy! As they walked up the long winding path, they saw things that chilled them to the bone! They heard sounds that frightened them. Maybe they should turn back. But the little boys, being very brave, just wanted to see what was in that house, so they went on, not deterred by the things they heard or saw. As they slowly made their way up to the door, they imagined what might be inside. Maybe it would be a witch or maybe a ghost! After knocking several times, the door slowly creaked open. To their surprise, a monster slowly came out to greet them. They were so scared that they couldn't move! What could they do? Then the little boy had an idea. He said, "Trick or treat!" Then the big scary monster, much to the kids'surprise, reached over and brought out a huge bowl of the best candies they had never seen. Wow, the kids thought, this was great! It turned out that the house was decorated for Halloween, and the big scary monster was just wearing a costume, just like the kids. Since they were the only kids, and were brave enough to go to the scary house, they could take as much candy as they wanted.
