There seems to be an endless supply of online resources to help you study the English language -- from entertaining activities and exercises to in-depth courses in all aspects of the English language. Learning about quantifiers, prepositions of place, plural nouns and adverbs can all be done online. If you have no understanding of the English language whatsoever, you may benefit from a tutor or guide in the initial stages of learning. Using a foreign country's search engine, you will be able to find English study material in many foreign languages. Once you gain more confidence, you can then continue your online study on websites solely in English.
Studying English at a language school has many benefits. You have access to skilled teachers and tutors with one-on-one tutoring if necessary. Language schools also offer a range of resources to their students, such as books and audio learning aids which help you study when you are not in the classroom. Being surrounded by other non-native English speakers can also provide a little comfort when you are studying English. Learning with others means you can boost each other's confidence as you learn and won't feel so isolated in the early stages. ESL (English as a second language) schools are all over the country and all over the world, in fact. A quick search online should result in finding a suitable language school in your area.
There are programs that teach English by total immersion in the language, cultures, food and lifestyles of native English speakers. Most easily explained as an "English Camp," it can be quite a successful method with candidates being "forced" to learn and understand English. A less invasive method of immersion is a self-enforced one. Surround yourself religiously with only English-speaking people, movies, television, music and books. Along with other methods of studying English, this can be a successful method also; however it requires a lot of self-control and discipline.
If you want to master the English language, you need to constantly practice. Perhaps this might involve speaking only English for a period of time, even at home. Recording your own voice and listening to it is a good way to identify words or sounds you need to practice more. Make full use of online resources, library books and study guides that are available. Ask native English-speaking friends to test you and give constructive feedback. Researching and practicing English is an effective method of studying English and is most beneficial when done in conjunction with another studying method mentioned above.
