Tìm 5 lỗi sai và sửa The big majority of students who make well in the Cambridge Proficiency Examination have learnt to use a good monolingual dictionary effectively. Such dictionaries provide information, not just about the meanings of words but about their pronunciation and grammar as well. A student who studies how to use a dictionary effectively will be possible to work independently for much of the time, and will gain considerable insight into the workings of the English language. He or she will be able to confirm the meanings of the words in a text which contextual clues are insufficient, pronounce words accurately by studying the phonetic transcriptions, and use words accurately both when speaking or writing. Make sure you make room for at least one good monolingual dictionary on your bookshelf- and then make sure you use it on a regular basis!
