Because it is gradual, from shallow to deep, and revolves around life, English verbs and prepositions start from the most commonly used, grammar starts from the most basic, the review and strengthening of old knowledge in teaching materials, and the key arrangement of new knowledge are all very good. And it is basically the same as the outline of primary education and higher education implemented in China. Once published, it began a lasting process. The new concept textbook is the best textbook, which can guide you to your goal.
There are four new concept English books, and their names are new concept English. New concept English has a long history, so there are a lot of counseling materials and exercises. I suggest buying New Concept English from Longman Foreign Languages Institute. 16, published by Foreign Language Teaching and Research Press. Each volume has textbooks, workbooks and teachers' books, and all textbooks have standard answers in exercises. Every book is about 30 yuan. Each book has two tapes. Every tape, 7 yuan. In addition, there are many other counseling books, you can buy a few, any version will do. Can complement each other, different counseling books have different exercises, and basically have standard answers. If you learn four books, your level will be very high. I suggest learning a copywriter and buying a set of corresponding materials. Maybe there will be a new version in the future. In addition, there are many online teaching and listening exercises of new concepts. You can download them to MP3, so you don't have to buy tapes. The advantage of online learning is that you can arrange your own time to study and repeat what you don't understand. The disadvantage is the lack of interactive question and answer, easy abortion in learning and difficult guarantee of learning progress. It's best to find a remedial class, and you won't give up studying after paying the tuition. I have to study for tuition. And under the guidance of teachers, you can take shortcuts and solve your own problems face to face. Otherwise, self-study is often a difficult problem for you, and you don't know if it's right if you delay time.
