To master a large vocabulary is crucial to the fluency in a foreign language. It is showed by the statistics which are unofficial but frequently quoted concerning the Cambridge First Certificate examination that those students with a vocabulary of less than 3,500 words are less likely to succeed in the exam. The latest research also indicates that native speaker of English knows at least 16,000 English words, when he has received education until he’s 18 or more. Unless you are proficient in a language such as Spanish or German, there is no shortcut to a large vocabulary: you have to depend on diligence and dedication. Of course, you can infer from context the meaning of some new words you come across in reading., but often you have to consult a dictionary to clarify the exact meanings. A practical method to learn new words may be reading widely, especially reading those interesting and exciting. Repeatedly, the same books is often beneficial to you: each time you read it you’ll learn different new words, and the familiar context also helps you to engrave these new words on your mind deeply.
