For the time being, no matter what the purpose of the student's postgraduate entrance examination is, it can be said that there are advantages for him or her to stand out from many candidates. Students who have experienced the college entrance examination and postgraduate entrance examination should know that the review of the college entrance examination is guided by high school teachers from time to time and supervised by parents every day. Candidates only need to prepare for the examination step by step according to the school's college entrance examination schedule; The postgraduate entrance examination review requires candidates to make their own decisions from deciding whether to take the postgraduate entrance examination to choosing the direction, preparing materials, preparing for the examination review, etc. the most important thing is to urge themselves to work hard day by day to achieve their goals. It can be seen that students who can be admitted to graduate school already have good quality in planning and self-management. Isn't this a great advantage? Therefore, tutors who can recruit graduate students should be happy secretly, because you have found a new force that can fight side by side and move forward together, and because you have found a new generation that may see further on your shoulders in the future. With this understanding, we began to discuss the teacher's consciousness.

Because we almost all choose mentors based on discipline or professional direction, and establish the relationship of "mentor graduate" by studying topics in the laboratory, the consciousness of mentors discussed in this paper is also limited to the scope of the laboratory, and try not to involve the topic of life mentors. Tutors should not rejoice in being the "boss" in the mouth of students, but should be honored to be the "guide" in the heart of students. As a tutor, it should be no problem to do well in their own research. Whether they can guide students to do well in research is another matter. "Tutor" is not just a simple title, it needs to fall on the word "guide". Graduate enrollment is like the beginning of a mountaineering journey. On the long way, you will naturally ask: can you climb the top? When will we reach the top? Should I quit? How do I exit? The teacher's consciousness is reflected in paying attention to the changes of students' state and giving appropriate tips or suggestions at the right time. Specifically, I think it is reflected in the following aspects:

（1） Respect students' time

Each tutor's management of his laboratory often has an obvious personal color, and each laboratory will gradually form a default working time. Students should know more about the situation before joining the laboratory. Once joining the laboratory, they can abide by the agreed time. Tutors respect students' time. On the one hand, they should respect students' learning time in the laboratory and should not arrange students to do things that are not directly related to research; On the other hand, we should also respect students' time outside the laboratory and should not arbitrarily occupy students' free time. It is difficult for graduate students to refuse the things arranged by the tutor. The tutor himself should know this, so try to avoid arranging personal chores for students.

（2） Help students know themselves

After entering the laboratory and starting to participate in scientific research, graduate students will find that the actual scientific research life seems very different from what they imagined when taking the postgraduate entrance examination. For example, it is not easy to get a certain experimental result, and they don't seem to like scientific research so much. Doing scientific research is definitely not the only way out for all graduate students. It's normal to feel uncomfortable in the laboratory. Only those who wear shoes know whether they fit or not. Tutors will meet all kinds of students: some students like to study new problems and often come up with new ideas, some students don't like to challenge new problems but can make the knowledge fascinating, some students don't think much but can implement the tutor's ideas very firmly, some students don't have much enthusiasm and investment in laboratory work, etc. On the one hand, tutors should stimulate students' interest and enthusiasm in scientific research. On the other hand, they should also respect students' real ideas. In getting along with students, they should gradually formulate training programs in line with individual differences to help students understand themselves more comprehensively. Whether students choose to engage in scientific research, popular science, natural science teachers or participate in non-governmental organizations in the future, as long as students really like and meaningful work to the society is worth encouraging.

（3） Improve students' self-confidence

When children take the first step, they will be greatly encouraged by adults, so they can walk and run slowly. Graduate students who join the laboratory seem to be about to take the first step in scientific research. Although the questions raised are not on the point and their ideas are childish, it at least shows that students have tried to integrate into scientific research, which is worth encouraging. Tutors can take the opportunity to guide students how to ask scientific questions and put forward their own ideas, so as to help students gradually build confidence. Laboratory group meeting is a good opportunity for tutors to communicate with students. Tutors should not only listen to students' research progress report, but also consciously train students' speech logic and expression clarity. If possible, try to support students to make poster displays or even oral reports at academic conferences, so as to enhance students' self-confidence in participating in scientific research activities step by step.

（4） Guide students to establish a good attitude

Perhaps the most indispensable thing in the laboratory is failure. How to face failure? This is a problem. Give up, may regret; Persistence may be painful. So how to face failure? Finding out the cause of failure is the best solution. Because to find out the reasons for failure, we can design ways to deal with it. In this way, we will forget failure and rekindle hope in our hearts. The tutor should timely analyze the experimental design with the students, find out the reasons for the failure, and guide the students to relax and start again. After living in the laboratory, the tutor can guide the students to establish such a mentality: failure is not terrible. Just find out the reasons and solve them. Another more important point is to encourage every student to be himself bravely and live his wonderful life. Everyone in the laboratory has different research topics, which means that everyone can think freely about their own research topics. The value of tutors is to fully recognize the uniqueness of each student, and then encourage each student to give full play and make their own characteristics in research. The latter point is very important for students to maintain inner peace in the face of various evaluations in the future.

How much of the above is just the consciousness of graduate tutors, not just theory. Now, when reviewing the qualification of graduate tutors and allocating enrollment quota, the most important measurement indicators are whether the tutors preside over the projects and the size of the projects presided over. There is little investigation on whether the tutors are ready to train students. Tutors have projects to do, which is naturally a good thing for cultivating students' scientific research ability. Wouldn't it be more ideal to cultivate students from the level of cultivating people?
