    “A lie can travel half way around the world before the truth can put its bots on.” That quote is attributed to Mark Twain. In today’s Internet world of “fake（假的）news”, lies spread even faster than the truth is having trouble finding its boots.

To make matters worse, most young people get news from social media sites where facts are mixed with rumors（谣言）, half-truths and complete lies. This has led to young people becoming confused. In the latest PISA, which tested 15-year-old worldwide on academic subjects, fewer than one in ten of the examinees were reported to be able to distinguish fact from opinion. A Stanford University study showed that students at all levels of education could not tell real news from fake news. In one instance, 80 percent thought that a paid advertisement was a real news story.

Fake news is spread by people who have a prejudice. They want to influence public opinion either for or against something or someone. It is important, then, for young people to recognize when they are being used and to be skeptical of online information.

Traditional media, such as newspapers and television, are still the more credible sources of information. Reporters are professionally trained to look for facts, and editors have the job of making sure those facts are correct. However, if you getting most of your information online, you have to be your own editor. In that case, the first thing to do is to look at the writer of a post. Is this person known to be credible? Does the site where you read the post have a prejudice? Next, look for other sources from mainstream media to confirm the information. In other words, by putting on your truth boots you won’t be fooled into chasing lies.
