We keep reading that TV is bad for you. If this is true, how come the current generation of TV-addicted kids is much smarter than we are? In my home, the only people who can work the remote control are the children.

Perhaps TV does educate you. For example, you learn a useful medical fact: A person who has been shot always has time to speak an incomplete sentence before he dies. “The killer was…” (dies)

But I guess the biggest things we learn from TV can be regarded as “Life Skills”. Bad things only happen on dark and stormy nights. Emotional breakdowns cause people to wander in the heavy rain without umbrellas. And contrary to what scientists say, the crack(霹雳) of lightning and the accompanying flash happen at exactly the same time, wherever you are.

I’ve even acquired useful geographical facts from science-fiction shows: Aliens speak English no matter which planet they come from.

Making use of what we learn from TV can improve our security. Consider these truths. If you are ever attacked by 20 bad guys, don’t worry about being outnumbered. The criminals will hang back and take turns to approach you in ones and twos just so you can conveniently defeat them all. Bad guys who are completely covered in black clothes always remove their black masks to reveal that they are in fact, aha, women.

TV also teaches us important information about escaping from danger. Watch and learn. (1) If anyone is running after you down a passage, you will find that boxes have been conveniently placed near all the walls you need to jump over. (2) If you are tall and handsome, you can run from any number of armed criminals, and every shot will miss you.

Be warned, however. If your name card says “henchman” (帮凶) and you are part of a group of plain-looking people trying to catch a handsome individual, a single shot will kill you. But don’t be anxious: TV also delivers useful information for bad guys. All cars are inflammable (易燃的) and have amazing shock absorbers that enable them to fly into the air and land without damage — except police cars.

TV even teaches us about TV. Whenever anyone turns on a TV, it shows a news flash about someone they know. They then turn the box off immediately after that news item.

When I tell people that I’m a professor of communication, they often are confused (1) what the term "communication" means. Many people think mass communication is the (2) type of communication, but mass communication is only one form of communication. The study of mass communication focuses on messages that are (3) over (4) such as television, newspapers, and radio. Other areas of (5) focus on the messages individuals send to one another. Some of the major contexts in which communication is studied (6) the interpersonal context, the organizational context, and the intercultural context. A scholar studying (7) communication, for example, might examine how married couples (8) with misunderstandings and the effects these misunderstandings have on (9) satisfaction. Organizational communication scholars, on the other hand, might study (10) the communication styles used by managers and their subordinates influence productivity and efficiency in a company or factory.
My area of specialization is intercultural communication. Intercultural communication is an (11) field of study which incorporates research from disciplines (12) as social psychology, sociology, cultural anthropology, sociolinguistics, and of course, communication. One of the (13) important areas of research addressed by intercultural scholars is how misunderstandings can be (14) when people communicate with Others from different (15) . To understand the process of intercultural communication, we must study how individuals’ cultural backgrounds (16) their communication behaviors.
The area of intercultural communication is a relatively new (17) of study even in the United States. While most Chinese students studying communication in the United States (18) on mass communication, there are some who are interested in intercultural communication and plan to return to China to teach and (19) research in this area. The work of these Chinese scholars on intercultural communication is important because it will help improve (20) between Chinese and Americans in the future.
