English is very interesting. It is not difficult to learn English well. However, it is important to find the most effective way to learn the language. I rarely look up new words in the dictionary, but I often try to guess their meanings in the reading. At first, I found it a little difficult because I could hardly understand everything that I read. But gradually I could get the general idea of th reading or the main information the reading passage gave. I never use an English-Vietnamese dictionary, instead I used an English-English dictionary, and this helps me a lot. In this way, I can use the new vocabulary correctly and naturally. I also keep my diary, and write short stories in English to improve my writing skill. As for listening, I listen to music and news programs boardcast in English on TV and on the radio. It is an interesting way to pratice listening. Modern equipment can help a lot in listening. For example, I use an iPod to record the news so that I can listen to it again and then I record voice and correct myself. I've joined an English-speaking club to better my speaking. I can make myself well understood when I speak to native speakers. I think in the future everybody in Vietnam can communicate with each other well in English.
