If your child has mobile internet access, it will be more difficult to monitor and control his or her internet use. Kids are turning to the internet for everything from hanging out with friends to shopping, which makes it harder for parents to keep track of their online activities. Fortunately, there are many choices for controlling what your kids see on their computers, laptops, and mobile devices. Content blockers and filters are great tools to use for younger kids. They allow you more control over where they go and what they do online. A content blocker can block some unhealthy websites or limit a child's search to the kind of sites. A content filter can scan sites and pictures and block those sites that contain certain words, key phrases, or content. Consider tracking software for older teenagers. This software enables you to see which sites your children have visited, tracking their path online. This tool gives young people more freedom to explore the Internet, but it also allows you to check that they are using the internet responsibly. Let your teenagers know that you trust them, but that you will be regularly checking that they are visiting appropriate sites online. Even if you use content blockers, filters, and trackers, you know that a lot of kids figure out ways to get around these, so it's important to remain alert . Remember that not all adult sites can be identified by blocker, filter, or tracker software. That's why it's important to talk to your kids about what to do when something inappropriate or scary comes up. Nothing can replace involvement and supervision by adults. Keep monitoring how your kids use the internet on a regular basis without getting into the role of internet traffic police. What is the passage mainly about? A) More and more kids have mobile internet access B) Some choices for monitoring and controlling kid's internet use C) It is difficult to monitor and control kid's internet use D) Kids are turning to the internet for everything

Ques:You hear this,"No wonder you are fat.All you ever d0 is eat."You feel sad."I skip my breakfast and supper.I run every morning and evening.What else can I do?" Basically you can do nothing.Your genes,not your life habits,determine your weight and your body constantly tries to maintain it. Albert Stunkard of the University of Pennsylvania found from experiments that"80 percent of the children of two fat parents become fat,as compared with no more than 14.percent of the children of two parents of normal weight." How can obese people become thinner through dieting? Well,dieting can be effective.but the health costs are great. Jules Hirsch,a research physician at Rockefeller University,did a study of eight fat people.They were.given a liquid formula providing 600 calories a day.After more than 10 weeks,the subjects lost on average 45 kg.But after leaving the hospital,they all regained the weight. The results were surprising:by metabolic measurement,fat people who lost large amounts of weight seemed like they were starving.They had psychiatric problems.They dreamed of food or of breaking their diet They were anxious and depressed.Some wanted to kill themselves.They hid food in their rooms. Researchers warn that it is possible that weight reduction doesn't result in normal weight,but in an abnormal state lust like that of starved non.obese people. Thin people, however,suffer from the opposite.They have to make a great effort to gain weight Ethan Sims of the University of Vermont got prisoners to volunteer to gain weight.In four to six months--they ate as much as they could.They succeeded in increasing their weight by 20 to 25 percent. But months after the study ended,they were back to normal weight and stayed there. This did not mean that people are completely without hope in controlling their weight.It means that those who tend to be fat will have to constantly battle their genetic inheritance if they want to significantly 1ower their weight. The findings also provide evidence for something scientists thought was...
