2. Don't quote more than one-third of things, learn to summarize and apply by yourself, for example, quote a few paragraphs, change the words in them into synonyms, and change the emphasized concepts into similar concepts. For example, organization theory can be used to prove motivation, and chemical models can be used in pharmacy (this depends on your major). Then, to sum up, the summary will be comprehensive and there won't be too much plagiarism.

3. Argument I think if it is the same as the original thesis, the undergraduate thesis doesn't matter, and the graduate thesis is not very good. ...

Copying and pasting the whole paragraph is definitely not good for your paper, but you should learn to describe it in your own words. HowNet itself is mainly a paper. If the whole sentence is consistent, it is considered plagiarism. If the cumulative proportion of the full text is too high, it will not work!

At present, there are many papers that plagiarize this thing, especially in China. I suggest you read more papers and write some of your own things from the perspective of finishing, so that you can copy less ~ ~ ~

Good luck.
