If you want to go abroad, I recommend: the intensive course "New German" published by Tongji University. This set of teaching materials is mainly written for overseas students to strengthen their study. The content is relatively new, with a large number of words, involving all aspects of German social life, and according to the requirements of DSH examination, some texts and exercises are selected pertinently. If the purpose of learning German is to study abroad, you can consider using this textbook. And you can use the Concise Course of College German as an introductory textbook. This book is annotated in Chinese, and the content is more interesting and easier to use than the newly refined one.

If you don't want to go abroad, and you have plenty of study time. It is suggested to use "Learn German with Me" as an introductory textbook, and then mainly study the intensive course "New Standard German" of FLTRP. This book, like Travel around Germany, is a German textbook introduced by FLTRP. Compared with domestic textbooks, the content is richer, involving all aspects of German social life, vocabulary and idioms are updated, and listening, speaking, reading and writing skills are emphasized, but the grammar explanation is not systematic and detailed enough. As a supplement, you can buy a grammar book online and recommend FLTRP's German Grammar Complete Book. This grammar book is divided into two volumes. If you are a beginner, take the first one. After you have a certain foundation, you can read Standard German Grammar-Detailed Explanation and Practice, which is more detailed and more difficult.

In terms of dictionaries, it is convenient to recommend Langsden Chinese dictionary for self-study, German assistant for software, and electronic dictionary "King of German" on the market.

Let's talk about other textbooks. Personally, I feel that the German course published by Peking University and the contemporary college German published by FLTRP are not very suitable for self-study. I am a German major, and the designated textbook for undergraduate study is contemporary college German. College German published by the Institute of Higher Education is a typical foreign language learning textbook in China. It includes text, vocabulary, vocabulary, text exercises (including verb explanation, translation, cloze, answering questions, etc.). ), grammar (the grammar of this textbook is mainly explained in Chinese, and it is better for beginners, especially self-learners) and grammar exercises. FLTRP aims at old textbooks, but the library has them and I haven't opened them. It seems that there are not many people using it now. In addition, new concept German (text translation, grammar explained in Chinese), basic German, Tongji University Press and New College German Foreign Language Teaching and Research Press can all be taught by themselves.

Pure hand-beating, I hope it will help you, and I hope it will be adopted. You can ask me if you don't understand.
