I have two suggestions that have worked well in my case: 1) learn vocabulary by semantic fields, that is, learn words that are similar but differ in key features. For example, learn together words like "think", "consider", "believe", "suspect", "know", "ignore", ... or nouns like "car", "bicycle", "motorbike", "bus", "tram", "train", "tube", "plane", "ship", "ferry"... etc.; and 2) I strongly recommend you to face the challenge of translation; do not just say what you can; you must force yourself to say what you still cannot say but have to say, and having to produce an accurate translation, say, from Chinese into English, is a fantastic way to detect where your vocabulary is inadequate and learn new words. Of course, reading as much as possible is also essential to achieve a really large and native-like lexicon.

You can widen your vocabulary by listening to your favorite English song. Read the lyrics first and try to understand them. You don’t have to translate the lyrics word by word, just try to find out what the song is all about. Pick some words or phrases from the song that you would like to learn. If necessary, look up their exact meaning in a dictionary. Now, to learn the vocabulary, all you have to do is listening to the song again and again (that shouldn’t be a problem if it’s one of your favourite songs). I hope this helps :D

Learn more words.

reading is the best way to improve your vocabulary ...
