Another way to improve your English is to keep a vocabulary notebook. You can get a special alphabetised note book or you can make your own note book. Each time your teacher teaches and a new word crops up, copy the word and its meaning into your vocabulary book. Bring it along with you everywhere and while you are waiting for the bus or waiting for a tv programme to start, just take it out to review it. Look at the way the word is used and how it is spelt. Draw mind-maps and pictures to help you remember. Use colours creatively to make the notebook special.
The last tip in building vocabulary is to use the new words you have learnt in your essays or in your journal. Remember to look up new words in your dictionary. Jot down the correct usage and sentences. Begin to use these words in your composition.Before long, you will certainly notice that you have increased your vocab and your English has improved.
