1. Academic search engines: such as GoogleScholar, WebofScience, Scopus, etc. These search engines can search papers in major academic databases around the world, including SCI journals. Enter the names of tutors in the search box, and you will find all their published papers.

2. Tutor's Personal Homepage: Many tutors will list their research results, including published papers, on their personal homepages. This information is usually comprehensive, including the title, author, published journal and date of the paper.

3. Academic Journal official website: If you know that your tutor has published papers in a specific journal, you can directly visit the journal official website and search for papers through the search function.

4. Library databases: Many university libraries subscribe to a large number of academic databases, such as JSTOR and SpringerLink. In these databases, you can search for tutors' papers.

5. Ask the tutor directly: If you can't find the tutor's thesis by the above methods, you can ask the tutor directly. They may provide the full text of the paper or tell you where to find it.

It should be noted that due to copyright issues, not all papers can get the full text for free. Some papers may need to be paid for, or obtained through the membership of academic institutions. In this case, you can try to contact your tutor or your school library to see if it is possible to get free or preferential access.
