When you come across a new English word or phrase, make a note of it! Look up the meaning in the dictionary, making sure you are aware of any grammatical information. (For instance, if you are looking up a verb, check to see if the verb can be used in a passive form, if it is followed by any particular preposition, and so on.) Check also for the pronunciation and use of a word. Is it particularly formal or informal, or used in certain word partnerships? For example, we say “do housework”, but “make an effort”.
