If your child has mobile Internet access, it will be more difficult to monitor(監(jiān)督) 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 paths 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 (警惕的). 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 (監(jiān)督) by adults. Keep monitoring how your kids use the Internet on a regular basis without getting into the role of Internet traffic police.

December 15, 2014

Dear Alfred，

I want to tell you how important your help is to my life.

Growing up, I had people telling me I was too slow, though, with an IQ of 150+ at 17, I’m anything but stupid. The fact was that I was found to have ADHD(注意力缺陷多動(dòng)障礙). Anxious all the time, I was unable to keep focused for more than an hour at a time.

However, when something did interest me, I could become absorbed. In high school, I became curious about the computer, and built my first website. Moreover, I completed the senior course of Computer Basics, plus five relevant pre-college courses.

While I was exploring my curiosity, my disease got worse. I wanted to go to college after high school, but couldn’t . So, I was killing my time at home until June 2012 when I discovered the online computer courses of your training center.

Since then, I have taken courses like Data Science and Advanced Mathematics. Currently, I’m learning your Probability course. I have hundreds of printer paper, covered in self-written notes from your video. This has given me a purpose.

Last year, I spent all my time looking for a job where, without dealing with the public , I could work alone, but still have a team to talk to. Luckily, I discovered the job—Data Analyst—this month and have been going full steam ahead. I want to prove that I can teach myself a respectful profession, without going to college, and be just as good as, if not better than, my competitors.

Thank you. You’ve given me hope that I can follow my heart. For the first time, I feel good about myself because I’m doing something, not because someone told me I was doing good. I feel whole.

This is why you’re saving my life.

Yours,

Tanis
