Article: It can be hard to encourage families of preschoolers to turn off the TV,but there are plenty of highquality shows that promote learning and positive relationships rather than violence,researchers noted. "Although clearly kids watch too much,what's more worrying is that they watch poor quality shows," said Dr Christakis,the lead researcher on the new study from the University of Washington in Seattle.His former survey of parents of threeto fiveyearold children showed the kids often watched violent cartoons and movies that are "totally inappropriate". For their study,he and his colleagues randomly divide 565 preschoolers into two groups.In one group,parents recorded notes about kids' normal TV viewing,without receiving any guidelines to reduce or change those habits.In the other group,researchers made visits and calls and sent monthly newsletters encouraging parents to replace violent TV with educational programming.After six and 12 months,parents reported their kid's angry,aggressive or anxious behaviors on a questionnaire.At both time points,children in the TV intervention program had slightly fewer problems than those in the comparison group.Boys in lowincome families seemed to benefit most from the change in programming,the researchers found. "The point is,this is something that is as effective as other things we do to try to guide behavior in children,and it's fairly simple," Christakis said. Another study published in Pediatrics found the more TV kids and teens watched,the more likely they were to have a crime or other problems in society.Children may imitate violence they see--or more time in front of the TV could simply mean less communication with peers and families,and worse performance in school. The American Academy of Pediatrics recommends kids watch no more than one to two hours of highquality programming each day.Researchers agreed parents should be mindful of what exactly their young kids are watching on TV as well."It's not just about turning the TV off,it's about changing the channel,"... Question: According to the researchers, _ . Yes or no, is the answer "parents should keep an eye on what kids watch on TV"?

Ques: Article: Old people are easy to feel lonely because their children are busy with their work and have little time to spend with them.Most of them have to be companied by pet dogs.However,it is sometimes impossible for some old people to keep pet dogs because they are too old or ill to take care of pet dogs. Experts are studying the influence of robotic dogs on old people's depression ,physical activity,and life satisfaction.Researchers are placing robotic dogs in the homes of lonely old people to see whether they can improve the quality of life for old people.Alan Beck,an expert in human-animal relationship,said,"Old people should be more active,challenged,excited.The problem is how we promote that,especially for those without friends or help.A robotic dog could be a solution." In the study,the robot,called AIBO,is placed for six weeks in the houses of some old people who live alone.These old people will keep a diary to note their feelings and activities before and after AIBO.Researchers will collect basic data for six weeks.Then,the researchers will review the data to decide if there are any changes in the life of its owner. "I talk to him all the time,and he responds to my voice,"says a 70-year-old lady."When I'm watching TV,he'll stay in my arms until he wants down.He has a mind of his own." The AIBOs respond to certain orders.The researchers say they have some advantages over real dogs,especially for old people.Often the elderly are disabled and cannot care for an animal by walking it or playing with it.A robotic dog needn't any exercise and feeding concerns. "At the beginning,it was believed that no one would prefer the robotic dog because it was metal and not furry ,"Beck says."But it's amazing how quickly we have given up that belief." Hopefully,these robotic pets could become a more valuable health helper.They will record their masters'blood pressure,oxygen levels,or heart rhythms.AIBOs may even one day have games that can help exciting older people's minds. Question: From the passage we can learn that old people can easily feel lonely because . Yes or no, is the answer "their children are too busy to stay with them"?
Ans: No

Article: People diet to look more attractive.Fish diet to avoid being beaten up,thrown out of their social group,and getting eaten as a result.That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists. The research team have discovered that subordinate fish voluntarily diet to avoid challenging their larger competitors."In studying gobies we noticed that only the largest two individuals,a male and female,had breeding rights within the group," explains Marian Wong."All other group members are nonbreeding females,each being 5-10% smaller than its next largest competitor.We wanted to find out how they maintain this precise size separation." The reason for the size difference was easy to see.Once a subordinate fish grows to within 5-10% of the size of its larger competitor,it causes a fight which usually ends in the smaller goby being driven away from the group.More often than not, _ is then eaten up. It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish.Whether they did so voluntarily,by restraining how much they ate,was not clear.The research team decided to do an experiment.They tried to fatten up some of the subordinate gobies to see what happened.To their surprise,the gobies simply refused the extra food they were offered,clearly preferring to remain small and avoid fights,over having a feast. The discovery challenges the traditional scientific view of how boss individuals keep their position in a group.Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves,so keeping their competitors small. While the habits of gobies may seem a little mysterious,Dr.Wong explains that understanding the relationships between boss and subordinate animals is important to understand how hierarchical societies remain stable. The research has proved the fact that voluntary dieting is a habit far from exclusive to humans."As yet,we... Question: When a goby grows to within 5-10% of the size of its larger competitor,it _ .
