College students often say "before" refers to presentation and report, which can be understood as the abbreviation of "presentation". In college life, pre is a very common word, which often appears in various occasions, such as course assignments, academic seminars, project reports and so on. In these cases, students or teams need to make slides and show their research results or project progress to the audience through speeches. This process is called "before".

In the process of preparing for pre, students need to organize their thoughts, collect materials, design slides and rehearse and revise them repeatedly to ensure that they can express their views smoothly and accurately in their speeches. Through pre, students can not only show their abilities and achievements, but also improve their speech skills and expressive ability, laying a good foundation for future career development.
