English is one of most important information carriers; it is used very extensively in every field of human life. For the needs that comply with the time development, the emphasis of English course reform is “changing the English course which puts on emphasis on explanation on grammar and vocabulary knowledge into the course which emphasis on train students ability of using language.” It also suggests that teachers should train students ability of using English on the basis of students interests, experience of life, their knowledge through the approach of practice, participate, cooperate and communication, and make the language learning course become the course of students cinch forming active emotion, active thinking and daring to practice, improving students communication and their ability of self-learning. Computer-assisted English teaching is the inevitably tendency of English teaching development. It has essential difference from traditional teaching mode .The traditional teaching mode emphasizes teachers teaching, and stresses through teachers best teaching method to receive best teaching result, but computer-assisted English teaching emphasizes the improvement of teaching method and lead students to draw assistance from computer to learn English, combine with teaching content, teaching process and computer assist to obtain best learning result.In English teaching, teachers make use of computer to do software, can create teaching scene. It also can make the teaching livingly and arouse the interest of students.

The Necessity of Using Computer-assisted English TeachingComputer-assisted English teaching is related to those who are interested in English or teaching English. In English teaching field, it obtains extensive approvment. Computer-assisted English teaching is good for motivating students to study English. Students are anxious to use computers. Many students are tired of traditional English classroom and are interested in this new teaching method. Computer can display written text and use sounds, motion pictures, and video. Students feel things are more real and more easily understood.In English teaching, teachers make use of computer to do software, they can create teaching scenes. It can make the teaching livingly and arouse the interest of students. Utilizing computer- assisted English teaching can provide drill of some forms; add teaching information and direct students learning methods. It drills students ability of listening, speaking, reading and writing.Now computers are entering more and more classrooms, the teachers are learning how to operate computer and how to do software through continuous training, Some people cant understand why the teachers computerize their classes and some of them consider computers are fashionable and luxury ornament. In order to know the necessity of use computer-assisted instruction, and urge more teachers to accept this modern teaching method.III. The Present Situation of Using Computer-assisted English TeachingComputer-assisted English teaching is the trend of times that it is used by every primary school, middle school and university in our country. Except some schools of faraway village, because they dont have enough money, but more and more school are using computer in their classrooms now. “The number of teachers using computer-assisted English teaching has increased markedly and numerous articles have been written about the role of technology in education in the 21st century. Although the potential of the Internet for educational use has not been fully explored yet and the average school still makes limited use of computers, it is obvious that we have entered a new Information Age.” (Kuang-Wu Lee,2002)“For example, in the past decade, numerous academics have examined the application of computer-assisted English teaching in Taiwan classroom. From the very start, teachers have realized that computers have enormous potential of special interest is the realization that CAET may be especially useful in the Taiwan situation where writing students are ofter at a low level of skill attainment and class size is large.” (Li Ming, 1988)Because of the economic situations in different areas are different, it is impossible that every primary school; middle school and university in our country. Use computer-assisted English teaching, but with the high development, in our society using computer-assisted English teaching for every school and university will be a common thing.IV. Brief Notes on Computer-assisted English TeachingFirstly, this text concludes what is the computer-assisted English teaching, secondly, it describes the features of computer-assisted English teaching in many aspects, thirdly, it talks about the using of CAI in English class, at last, it talks about some general problems in the computer-assisted English teaching. It wants to draw peoples attention to the significance of computers in English teaching, and stimulates more and more teachers to devote their efforts on this modern instruction method. 4.1 What is the Computer-assisted English Teaching? Computer-assisted English teaching is the inevitably tendency of English teaching development. It has essential difference from traditional English teaching. The CAET emphasizes the improvement of teaching method and lead students to draw assistance from computer to learn English, combine with teaching content, teaching process and computer assist to obtain best learning result.4.2 The Special Features of Computer-assisted English Teaching4.2.1 Show Large Capacity of Non-sequential Messages.Computer can store an abundance of messages. It may include courses or knowledge connected with a certain object; learners can skin through all knowledge and choose the part that they are interested in to learn. At first, they can learn step by step or jump to any part teachers assigned.4.2.2 Students Can Control the Learning Context and Learning Speed Themselves.Usually, the CAI system permits to choose teaching content, when students master the first part completely, computers prompt them to enter the next part. In this way, students learning progress will not be limited by time or place. They can control their learning speed.4.2.3 Teaching According to Each Students Reality.Through mutual activity, such as raising questions, making judgment, the CAI system can analyze each students ability and learning condition, and adjust learning course automatically. By this way, computer can teach according to individual student and give them immediate feedback.4.2.4 Make Students Learn Enthusiastically.In CAI system, students control the speed of teaching and learning. Computers contain several mutual activities, such as sequentially raising questions. Showing feedback and manipulate teaching course, stimulating vacation. Students are in active and initiate state in CAI circumstance. They will not get tired easily and be interrupted as in passive learning course. Thus, they can get better result.4.2.5 Computers are Convenient to Be Used.Computer-assisted instruction is a kind of new technology, so some teachers think it is complicated in usage. Actually using a computer in an English class is as easy as using a recorder. In very short time, many teachers handle it masterfully. They use it to deal with some difficult and dull jobs, such as recode the students achievement, check the objective exercises. Its practical and convenient.4.3 Computer Can Help Students to Read and Write.4.3.1 Computer Can Help Students to ReadIn English reading class, computer should focus on meaning and stress reading comprehension.Learners should have opportunities to work with whole, meaningful texts. Programs that offer learners a chance to process large chunks of related text, rather than bits and pieces of unrelated language fragments, allow students to use and extend what they know about reading comprehension. Also to work with word-recognition programs that stresses the use of word meanings in conjunction with phonics and structural analysis. Care must be taken to make sure that, when programs feature the study of individual words and phrases, they are offered within a contextual framework that helps them make sense to the learner. Assessment programs for teachers should also be provided in meaningful context.In English reading class, computer should foster students active involvement and stimulate their thinking.Learners should have opportunities to discuss the purpose of the computer task or program as well as its nature. They should be aware not only of what they are supposed to do but also of why doing it is important, to make decisions that control or influence the computer task. Programs that build in opportunities for students to make choices and test predictions help them learn to think and act on their own rather than merely react to someone else's thinking, to monitor their own learning. Tasks that offer students opportunities to self-check and correct their own errors support the development of independent learners.In English reading class, computer should support and extend students' knowledge of text structures.Learners should have opportunities to encounter a wide variety of text structures upon which to apply and refine their comprehension skill. A variety of narrative and expository structures should be provided. Commercially prepared, teacher-authored, and student-authored materials should also be included. Reading instruction can take place through all kinds of computer-based materials, not merely those designated specifically for that purpose, to experiment with text in creative ways to suit their purposes. When students reorganize a story or an informational piece on the computer, they are employing and strengthening what they know about the structure of texts.In English reading class, computer should link reading and writing.Learners should have opportunities to create text with the computer for sharing and use with others. When students input information into the computer for someone else to retrieve and use, they must compose with the reader in mind. This frequently involves making explicit use of what they know about what makes a text comprehensible. Revision and proofreading strategies clearly involve the combined application or reading and writing skills.4.3.2 Computer Can Help Students to WriteComputer for writing help students with developing ideas, organizing, outlining, and brainstorming. Templates provide a framework and reduce the physical effort spending on writing so that students can pay attention to organization and content.Writing is taught by the process approach or by a traditional method, one of the barriers to producing good writers is that students must use pencil and
