Here's the completed passage with the words in the box:
E-mail and chat rooms let children communicate with friends and family members. They can also allow children to connect with people that they have never met in person. Knowing a little about each of these communication services can help parents keep children safer while online. Through e-mail, important users can easily send and receive messages. These messages may also have text, audio, and picture files attached. Signing up for an e-mail account is simple because most services offer them for free. Sometimes, these messages contain viruses, or other bad content, so parents should warn their children about that. Chat rooms are online hang-out spots where anyone can talk about anything - current events, books, and other common interests. Users often do not know each other in real life, so it is important that parents keep a close eye on the content of any conversations.
