I love reading. At age 6, I could be found reading Harry Potter, a difficult book for a 6-year-old but I (enjoy) it all the same. soon became obvious that spelling for me was not difficult and I had a wide vocabulary. This is one way I benefited reading at such a young age.
My advice for you as English learners would be to read the English novels you have often read in your native language. Reading novels is a great way of (improve) your vocabulary and spelling without realising it as you are absorbed(全神贯注的)in the storyline. You know the sorry well, so its (usual) easy to follow it in English even if you do not understand every word.
This is another essential(基本的)point: it's not necessary (understand) every word. If you understand the (mean) of the sentence, each word is not necessarily important. Quite often, if a word is used several times in a text, you'll gradually get an idea of it means.
Give it a try. If you like reading yon could open up whole new world of literature.
