Research of Computer Assisted English Teaching Based on Corpus

Abstract

In the present English teaching and English learning, computer-assisted language learning mode has become a way to comply with the requirements of the information age learning. All kinds of teaching software and learning system, through the use of advanced technology, will vocabulary learning content and a lot of pictures, text, audio and video data. Students in learning vocabulary, text, sound, like, you can choose according to their own specific situation learning content and way, such not only can stimulate learners' interest, improve the efficiency and quality of vocabulary learning, also can cultivate learners' autonomous learning ability. The brief introduction of Corpus is a language according to certain principles, applying the method of random sampling, collecting naturally occurring language in a row. It uses text or discourse to build a large electronic text library with quite big capacity. From its essence, is actually random sampling on the use of the natural language, and a certain size of language sample represents the general application of language in one study. On the other hand, linguistics, based on the corpus, objectively describes English, and the research of which is the application of language called performance, rather than language skills (competence). Therefore, corpus is not a new subject, but a new study method, with real language data as the research object, analyzing a large number of language facts from the macroscopic Angle, and finding the rule of language in it. It adopts probability method in the analysis of languages, with actual use of language phenomenon the emergence of probability based on an analysis of the various aspects of the language. As the language materials in the are the practical application of language in reality, therefore, the research results of linguistics has the reliability and authenticity. The development of linguistics has roughly experienced three stages: the first stage, from the early 18th century to the 1950s; the second stage, from the 1960 s to so 1980s; the third stage, from 1980s till now. The first stage belongs to the early development of corpus, and is the development period of all kinds of manual before the appearance of computer corpus. Although the collected by hand is very little, sample representativeness is not strong, and the processing and analysis work is voluminous, early still plays an important role in the following areas: the bible and literature research, dictionary compiling, dialect research, the study of language education. Because of the rapid development of computer technology, the second phase of construction of has the main characteristics with the rise of electronic corpus. The capacity of increases and the species grows in this phase. In the third stage, has rapid development, the species increases greatly, which helps people research more deeply, and is widely applied to various fields related to language.
