I introduction of institutions and majors

Harbin Institute of Aeronautics and Astronautics: 1987. In June, with the approval of the Ministry of Aerospace Industry, Harbin Institute of Technology merged the Department of Control Engineering and the Department of Radio Engineering to form the Institute of Aeronautics and Astronautics. This is the first college in China to train senior aerospace talents and engage in aerospace high-tech research, and it is also the only permanent branch of the International Astronautical University in Asia.

In the early 1990s, the school added two majors, laser and optical engineering, and with the support of the Ministry of Aerospace and the assistance of China Academy of Space Technology, two aerospace majors, satellite engineering and aircraft environmental engineering, were newly established.

Aerospace engineering: the aerospace major is a major in aerospace research. The training goal of aerospace specialty is to train senior engineers and researchers who have good basic knowledge of mathematical mechanics, basic theory of aircraft engineering, overall structural design, strength analysis and test ability of aircraft, and can be engaged in structural design and research, structural strength analysis and test, and general mechanical design and manufacture of aircraft (including spacecraft and launch vehicles).

Second, the first trial

English

Vocabulary: Before I officially started the postgraduate entrance examination in March, I had a love affair with words. I put all the words I didn't know in my notebook for specific memory.

Then when I officially started the postgraduate entrance examination, I memorized the vocabulary in this book directly and started the second round of sorting out what I couldn't remember with a book. In my opinion, the two most important points in memorizing words are pertinence and repetition. Targeted, that is, as long as you remember what you can't do, don't waste your time on words you already know; Repetition means reciting the same group of words at least three times a day according to the law of memory (adjust the number of times according to personal circumstances), and constantly beating that part of the brain, so you can remember it well. In addition, it is suggested to use examples to make words and remember words in context. Personally, I use the European dictionary, which contains many examples and phrases. Of course, memorizing words is not limited to one or two word books, and what you can't learn later should also be accumulated.

Reading: I recited the vocabulary again in March and found that it was almost enough. I didn't want to go straight to the real questions (those are real questions, which are more precious), so I bought Zhang Jian to read 80 articles and practice my hands first. I personally like this book very much. Although I made a big mistake for the first time and doubted my life, the style and ideas of the articles in it are very close to the real questions of the postgraduate entrance examination. It is said that I have taken the postgraduate entrance examination before. )。 Later, I even bought two brushes, because I couldn't do the real problem four or five times. But this step doesn't have to be done, it still depends on the individual. Many seniors and sisters suggest that you only do real questions and don't have to do other reading. I don't need to spend time on grammar and long sentences in the early stage, and I haven't seen any videos.

Then I finished 80 articles in a month or so, and began to do real questions in early May. I do the real questions within a limited time and finish the parts except the composition in two hours. Of course, it also depends on personal habits or the speed of doing the questions, as long as I leave enough time to write the composition. The real question of 98-04 is different from the following questions, so there is no need to limit it. Just use it to practice your hands. 05- 19 needs to be done seriously! Some people are used to leaving the last few sets of pre-test simulations, which is ok. Here is a very important suggestion, which is translation. Translate all the four books in recent years! The process of translation is also a process of understanding the article word by word, accumulating all the words you can't understand or familiar with, and memorizing them directly later. This process can not only train you to break up long and difficult sentences and improve your reading ability, but also train your translation ability. After reading these 80 articles, your translation level will be improved qualitatively. Of course, this doesn't mean that you can browse it yourself. If you want to improve your translation level, you have to look at the gap between the standard translation (in the Yellow Book) and how people use words to make sentences to speak human words (in the early stage, you didn't translate human words at all …), so that a little imitation will be closer and the later effect will come out. Although it seems like a waste of time, it is actually a good deal. For example, I do the problem in one day and translate it in two days (turning two articles a day for half an hour), and I will finish it all in July. There is enough time for you to do the real questions four or five times later. But from the second time on, the real questions are more than just doing the questions and accumulating words. It's time to start studying the ideas of the questions, because there are basically routines in the reading questions of the postgraduate entrance examination. After three times, you can classify the wrong questions by type, aiming at lightning protection. For example, I later divided my mistakes into six categories: case reasoning, article title selection, author's attitude, detailed reasoning, case purpose and sentence/meaning, and then put similar mistakes together to find out the rules and routines. After this step, after reading some questions, I can basically know what to choose ... One of my senior sisters said that she had done the real questions six or seven times, but I couldn't. After four or five times, I will vomit. I don't think it's necessary to force the number of times. Just do whatever you can summarize and absorb.

New question type: there seems to be nothing to say about this, only the classification and summary method. Generally speaking, there are two kinds, sentence sorting and paragraph sorting, depending on luck, because sentence sorting is basically simple and paragraph sorting is generally difficult. The breakthrough points of sentence sorting I summarized are timeline, characteristic word echo, contextual cohesion and tautology. Paragraph ordering includes but not limited to these, as well as pronoun anaphora, content consistency and logical cohesion. Specifically, it is necessary to classify and study by yourself. Be careful when doing this kind of problems, because there are often more than one mistake (in reverse order).

Translation: This can be practiced twice on the basis of translating and reading articles before, mainly translating literary speeches according to standards, learning word order arrangement and some translation skills. I have read Tang Jing's book Division and Combination, and I think it's ok. He will teach you to split long sentences according to meaning groups. You can have a look if you are interested.

Personally, I think translation still lies in language. After all, everyone can split sentences, and then the translation given in his book is very different from that given in the Yellow Book. I stand in the yellow book.

Composition: This is the highlight of the whole exam, and it is also the most troublesome, and the cost performance is really low. For example, I spent a lot of time on it. I started reading Zhang Jian's book in October and made a template for a long time. It turned out to be of little use. It is foolish to scribble in the examination room. If you want to make suggestions, there are two main types. If you have a good foundation, you can make your own template (if you are strong, you don't even need to prepare, you can accumulate some corpus to write on the spot). Generally, you just recite the template or recite the full text directly. There is really no need to waste too much time on this piece. It is better to take math and professional courses and get faster grades. Wang Jiangtao is not recommended in this book. After reading it, I know that the model essay sucks. I really don't understand how his word of mouth is made ... If you don't believe me, you can look at Zhang Jian's composition book and you will know the difference.

In addition, take a look at the bets before the exam. He won n times.

politics

Xu Tao Intensive Class+Leg Sister Skill Class/Punch Class+Small 1000+ Small 4/8+ The final pre-test simulation papers of all teachers are memorized with the summary version of Small 4 (don't memorize the original Small 4 directly, the logic is not enough).

Review began in September. I watched the video first, then brushed the question 1000, then made a single choice and then made multiple choices. Doing 1000 once is equivalent to going through the knowledge points twice, because there is a high degree of coincidence between single choice and multiple choice. As soon as the brush-off applet comes out, do it when you have time. Don't be idle Almost all the simulation papers of famous teachers were finished before the exam.

Recite the recitation part half a month before the exam and get familiar with the skills of the skill class. Political exams are very accidental. Maybe if you are lucky that day, you will get 80+ in the exam, and it is easy to review 60+ in a down-to-earth way.

mathematics

Students with math subjects may spend most of their preparation time on it, which is normal, but the time invested is not necessarily proportional to the result. It is not that it is particularly difficult to take the postgraduate entrance examination for mathematics, but that most people's learning methods are not suitable. Many students may study math all day while preparing for the exam, but most of the time is spent watching videos, so the effect is very little. The reason is that they don't practice enough. Reviewing math definitely requires you to do more calculations yourself, rather than thinking with your eyes. Learning mathematics requires more ideas of your own, and the efficiency will be improved.

Of course, practice is also exquisite. Some people often practice, but they may still fail the exam because they practice what they have mastered and are very skilled. Any skill should be improved in a place where you can't but it is very important. Practice more, practice what you don't understand. I think this idea is applicable to any other subject.

Mathematics is also divided into three parts: the so-called basic strengthening and sprint review.

The first is the basics. It is not recommended to watch videos directly with basic knowledge, because the basic knowledge is relatively simple and you can learn it by reading. Therefore, at this stage, reading and doing the examples in the book also take time to finish the 660 questions of Li Yongle, but there are also many mistakes.

Then there is the strengthening stage. At this time, you can focus on your own unfamiliar courses and do more questions. In short, you should learn from the mistakes you made in the basic knowledge, the problem set you bought and the problem set. The level at this stage is probably stable. After reading the previous questions, you will find that many contents are no longer a problem, but you are not very skilled in some places, because the overall topic logic is not too clear, such as the number three pays attention to the sequence.

Drawing a mind map is to sort out the ideas when doing daily problems, then find out the thinking direction and special case, and refer to the thinking logic of your own mind map next time, so that you can find a breakthrough for the problems you can't.

For example, the probability theory of postgraduate entrance examination is monotonous in content and can be routine, which can avoid spending a lot of time reviewing repeatedly. To help quickly review your weaknesses and priorities, I made the following mind map.

In short, make it look like you can understand it, add content to it while learning, and finally review it much faster.

In the final sprint stage, it is still the wrong question, and then do the wrong question. Doing wrong questions can help you understand a lot of knowledge. If not, you can look at the analysis. If you have a solid foundation before and are fully capable of understanding the analysis, but you still have to do it after reading it, slowly find out when you will get stuck when you do the problem, so that you can make progress. During this period, in order to train the speed of problem-solving, I basically bought a set of simulation questions from all mainstream teachers in the market, including about 6 sets of Li Yongle, 8+4 sets of Zhang Yu (basic and high marks), 6+4 sets of Li Lin and 3 sets of Li Yanfang. After that, the time to do the problem can be accurately grasped.

Specialized course 824 Operational Research

Operational research, a specialized course, is a complex subject at first glance, but relatively simple after learning it. I went back and forth many times according to the book on operational research written by the party teacher, and finished all the after-school exercises, as well as the real questions over the years. I can be roughly divided into two processes: passing basic knowledge and passing real questions.

The first is the basic knowledge. Because it is a cross-exam, I study operational research with mathematics (for fear that the content can't keep up). During this period, it may take a long time for an algorithm to solve a problem, and sometimes it may take more than 1 hour to solve a problem, and I often make mistakes. At this time, I sorted out the answers to the exercises after class while studying, and I also sorted out the short answers for future review. During this period, I listened to Huang Lijuan's teacher CCTALK's explanation of operational research, which was very helpful.

I have also listened to the 824 problem-solving skills explained by the seniors on the shore, which is also very helpful.

In addition, practice the real questions. Pre-practice helps to speed up the practice of real questions in the later period, and can also help you realize your weaknesses. When the real problem is finished, you can go back and do the wrong problem, brush it again, and then find a simulation problem to practice. It will be much more stable to do the problem again at this time, and the subject will not have too much fear.

If we pass the initial exam, then we can have a good year happily and start preparing for the second exam!

Third, the second interview

The overall admission ratio of the aerospace engineering major I applied for is still relatively ideal.

The second interview includes three categories: 10% oral English, 10% listening, 20% professional knowledge and 60% interview, in which oral English includes self-introduction and question and answer in pairs. This requires us to prepare our English self-introduction in advance, so don't be too nervous when answering questions, just want to speak slowly. In listening, I bought a pamphlet about the second-round exam English listening in advance, so I don't have to repeat the questions, just do it once; Professional knowledge is optional (electrician and electronic technology, mechanical drawing foundation), and I chose mechanical drawing foundation. At this time, it is often not cost-effective to understand the knowledge points in the textbook thoroughly. You can look for the previous re-examination questions or the examination questions of this course before Beijing University of Technology, and make the questions clear, and you will be fine! For most colleges and universities, the interview is still the most important and often criticized process, so students from other schools must be more prepared. The interview examines the comprehensive level and has no scope. As far as my second interview experience is concerned, aerodynamics and heat transfer account for a considerable proportion. Everyone must focus on reviewing some commonly used knowledge points (specific impulse, Raphael nozzle, three laws, etc. ) should be clear and can be answered. I believe that after reviewing, no matter how difficult the teacher is, we can still cope.

Four. suggestion

When you feel that the postgraduate entrance examination can't go on, I'll teach you a good way to go on: imagine what your personal reward will be if you succeed in the postgraduate entrance examination. Who will be proud of your success? Imagine walking on your favorite campus after graduate school. Remember this feeling. As long as you feel that you are about to give up in the face of temptation, you should think about this feeling and give yourself positive psychological hints. As for whether I can get in, what should I do? Come on, whatever! We must do a good job in energy management during the postgraduate entrance examination: I have three suggestions, 1) to ensure 7-8 hours of sleep every day, so that the brain running at high speed during the day can rest; 2) Exercise 2-3 times a week to improve immunity and enrich energy; 3) The most important thing! Be sure to eat breakfast, food can ensure blood sugar balance, and research shows that blood sugar content is positively related to your willpower.

Too many people don't work hard for fear of not being rewarded, which is irresponsible for the future. Just as it's great to waste your time now, it will be bitter in the future. Think about what you will be grateful for now. Now you must form an alliance with your future self. Please be kind to yourself in the future!

Come on! Graduate students!
