Choose targeted documents, 1, keywords, keywords, keywords must be selected, so as to ensure the comprehensiveness of the content you want. Because, by changing keywords, new content can appear.

2. Search a scholar's SCI, get to know a scholar who has made achievements in this field, and find his recently published articles.

3. Literature Review Retrieval If there is a review or breakthrough related to your own topic, you can find those original research papers according to the corresponding references.

4. Pay attention to the reference value of the article. The influence factors of publication and the number of citations can reflect the reference value of the article. But pay attention to how other articles that quote this article evaluate this article.

Method of reading literature: 1. Note abstract: Abstract can be said to be a window of the paper. Most articles read abstracts, and a few articles read full texts. There are not many really useful full texts. Excessive pursuit of full texts is a waste. Don't go to extremes. Of course, it is also wrong to read only the abstract. After simply browsing the titles and abstracts of most articles, you can generally grasp most of them by directly looking at several structures, titles and directories.

2. Read through the full text: When reading for the first time, you must be serious and try to understand the general idea of each sentence. It's best not to look it up in the dictionary first. Because the purpose of reading a thesis is not to learn English, but to get information, after looking up the dictionary, my mind will be in a mess and I often don't know what it means to read a complete text. You can mark the new words while reading, and then look up their meanings after reading the whole text.

3. Summary: Long articles are easy to forget. Fortunately, although the sentences in the paper are long, there are not many sentences in each paragraph, so each paragraph can be marked with a title by a phrase.

4. Establish a sentence structure and grasp the theme: There are tricks to reading the original English literature. We know every word after reading it, but we don't know what he is saying. This is the biggest problem. When reading, you will certainly see a large number of relational conjunctions, which lead the full text.

5. Increase reading: As I just came into contact with this field, I have no idea about many issues, so it is very difficult to read and I can't understand many contents. Later, with the increase of reading volume, it can finally be integrated. So for beginners, pay attention to the number of documents read. If you accumulate more, you will naturally change from quantitative change to qualitative change.

Improve reading efficiency. 1, concentrate on reading documents: the more time you spend reading documents, the more time you waste. Pay attention to time, it is easier to connect and form an overall impression.

2. Make records and marks: the copied or printed documents are marked or annotated directly with a pen. Documents in pdf or html format can be highlighted, or you can use an editor to change the text color. This is another important means to avoid wasting time. Otherwise, it is equivalent to not reading it.

3. Reading order: Choose the appropriate order according to the reading purpose. Generally, first look at the summary and introduction, then at the conclusion, and finally at the results and methods.
