    Grammarphobia  is the fear of grammar. This fear attacks almost everybody at one time or another, and it's most likely to strike during English or language arts classes. Even people who love reading and writing

have been known to get feverish and insecure when they are aware of the possibility of turning in

homework with grammar or spelling mistakes. Though writing may be enjoyable, being corrected is

definitely not!

     Grammarphobes, it's time to put your fears behind you.Grammar isn't that dreadful (可怕的). Here's

why. 

     Let's assume you like hearing and telling stories and that you enjoy joking with friends. You probably

also like emailing and instantmessaging.  Well, what do you think makes all these possible? Grammar!

     Grammar is simply the art of putting words together to make sentences. Whenever you use words to

express yourself, you're using grammar. You do this all the time without even thinking.

     So why think about it? Because good grammar helps you convey the ideas you intend. If your words

aren't right, or if they are not in the right order, the person you are talking to might get the wrong idea. This can have embarrassing results.

     Grammar helps us understand each other.  It's like a manual (手册) for assembling the words in your head. You have to put your words together the right way if you want them to make sense. They can't do

what you want if they aren't put together correctly.

     What if everybody you know had a different manual? How would you agree on what others' words

mean? People with different grammar manuals might be speaking different languages.

     Communicating is similar to playing cards.  To make sense, we have to play the same game, by the

same rules. What are the rules for playing the game of English? You already know most of them without

having to open a book.
