If we want to cultivate our ability in this field, we need to ignore the things in books, because everything in books is the most basic thing and the basis for our deeper understanding. After learning professional knowledge well, we choose to study more scientific research literature, insist on reading a paper and literature related to our major every day, and combine our professional knowledge to master it at a deeper level. In this process, I not only learned new knowledge, but also cultivated my own way of thinking in scientific research, which will be very beneficial to students themselves.
Another way, I think, is to ask your professional teacher for advice if you don't understand the questions after reading the papers and documents every day, so that the teacher can analyze them from a more mature angle, so that we can have a correct way of thinking and leave a good impression on the teacher.
In addition, in addition to reading more literature, you can also apply to the teacher to participate in the teacher's research group. Even if we do some manual work in it, we may not understand the process of the experiment at first, but don't be afraid. Slowly, we can gain a lot from it, understand how these scientific research data come from and how these scientific research processes are carried out. If we are willing to study these things hard, we will certainly achieve something in scientific research and believe in ourselves.
