      When students think of learning a foreign language, the first thought is of books, exercises, and audio

cassettes. Those are important to learning but sometimes a little bit boring. Therefore, it is time for us to

spice things up a bit.

      Things like a cellphone can keep your interest level high. It's a perfect study material. You have it with

you day after day, you are familiar with how it works and you can use it to practice whenever you have time.

You don't need to have your books by your side or stay in your room to listen to tapes. Let's take a look at

how to add your cellphone to your study tools.

      Set up your cellphone to use the language you want to study. Go to the menu, find settings, locate

language and change it to English or Spanish, which benefits your language learning.

      Look at the buttons and connect those items with the new vocabulary. This enables you to master simple

words and phrases with little effort. For example, each time you open up your cellphone you'll see "messages",

"games" and "calls made". These words begin to take root if you see them again and again.

      When you have time, take out your cellphone and start hitting buttons. You'll be surprised at all the

vocabulary you can learn by playing with the different menu items. Some things you'll recognize immediately

and others you can guess just by where you find them.

      It can keep your learning fresh and interesting. And that's important because boredom is a big problem

with language learners. You need variety and a cellphone is one way to get it.
