When I was in college, I studied coal mining. In our major, I learned more about coal mining, and we also practiced it. But for us, there is almost no need to do PPT, so many students in our major will not do PPT even after graduation. In addition to our major, there are many other majors that don't need to do PPT, so many college students can't do PPT. 2. College students have fewer opportunities to do PPT.
When I was in college, on the one hand, we hardly did PPT in our major, on the other hand, even if we participated in some competitions, college students had fewer opportunities to do PPT. Generally speaking, there are many teams participating in a game, and there are usually five or six people in our team. At this time, only one person needs to do PPT, and others will sort out some materials, so there will be fewer opportunities for college students to do PPT. 3. Some college students are lazy and will not take the initiative to do PPT.
Just like my major, one of my roommates is lazy. Even when we are in a competition, he won't take the initiative to do PPT, so for him, there is almost no opportunity to do PPT actively in college, so he won't do PPT.
To sum up, I think many college students can't do PPT, because on the one hand, many majors don't need to do PPT, but they need to do other things. In addition, some college students are lazy and don't want to do PPT, so they have fewer opportunities to do PPT.
