I love reading. At the age of 6, I could read Harry Potter, a difficult book for a 6-year-old, but I (enjoy) it all the same. It soon became clear that spelling for me was not difficult and I had a wide vocabulary. This is one way I got from readingsuch a young age.
(I) advice for you as English learners would be to read the English novels which you have often readyour mother language. Reading novels is a great way of (improve) your vocabulary and spelling without knowing it as you are absorbed(全神贯注的) in the story. You know the story well, so it's (usual) easy to follow it in English even if you don't understand every word.
This is anther way of basic 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 (time) in a text, you'll gradually get an idea of what it means. Have try. If you love reading you could open up a whole new world of literature.
