       When you want to find some information, do you first think of the Internet? Now, more and more

students are using the Internet instead of using books. But we can't completely believe the Internet.

       Even though it's quick and easy to find information online, many online sources may not be true, for

anyone can publish a web page or website. That's why we must consider the following before deciding

whether or not to use the information:

       * Use sites that end with . edu,  . com,  . gov, or . org.

       * Use the latest information you can find.

       * Make sure the writer of the article or site is credible(可信的) .

       * Does the writer list his or her qualifications(授权)  to write on the subject? Have you seen this

writer's work before?

       * Where did the writer get his or her information? Did the writer get it from first-hand sources or

another expert? If the writer doesn't say where the information came from, don't use it.

       * Who is publishing the site? What are the writer's goals in publishing information?

       If you're not sure about a source, it's always best to check with a parent or teacher. When using an

online source, make sure you cite(引用) the source so that your readers know where you got your

information.
