1.1 The background of the Study
Language is the most important means of communication. We cannot live alone, so we need communication with one another to fulfill our necessities. The
function of language is usually in the form of such phrases as by which man communicate Corder, 1973:32. It means that someone who wants to
communicate with another has to use a language as a means of communication. It is important to study language because without language we cannot communicate
with each other. In Indonesia, English is the first foreign language which is taught since
elementary schools until universities. English is the primary international language. Every international meeting always uses English as a means of
communication. Thus, English is not only used in the country that has the same historical background but also spoken by many other countries in the world.
So, the students in Indonesia learn it. If we know about English, we can communicate with foreigners. So, English is important to be learned especially for
the students. Many books of sciences are written in English. English is difficult to study. It is because of the differences between
English and Indonesian. The different system of English and Indonesian happens not only in grammar but also vocabulary, pronunciation and spelling. So the
students often make errors in studying the foreign language.
