(2025·甘肃白银一模)
When I started my Ph. D., I knew my work was producing much waste, but I took it for granted. That all 1 one day when I saw plastic waste piled against the wall.
I went to my adviser and decided to create 3D - printed lab 2 out of our waste. But the process of making these tools didn't go smoothly. After months of 3, I felt worried about my dream.
It was a 4 when my colleagues were eager to join us. We created a group devoted to 5 other greener ways. We began meeting every month to discuss some 6. We introduced new recycling bins to each lab after learning that some waste could be recycled if it was sorted 7. And we also tracked the energy consumption of lab equipment. By doing these, we could create 8 on how to use each device. Our most energy - hungry devices were the ultra - low - temperature freezers, which caused much trouble. So, we started to 9 it, asking labs to remove samples that were not 10 anymore and make the most of the remaining ones. Through those 11, we managed to increase the temperature of several freezers after realizing some samples didn't have to be stored so 12.
I'm still disappointed that I couldn't 13 my 3D - printing dream, and I'm determined enough to keep trying. I've also learned that if one 14 isn't working, sometimes it's best to take a step back and look for other solutions. I'm 15 that with my colleagues' help, we were able to do that.
