Taking Guizhou University of Commerce as an example, the author pointed out the problems in current Japanese language teaching in universities and proposed improvement measures from three aspects, aiming to explore a suitable path for Japanese language teaching in commerce colleges.

Before the formal construction of a building, it is necessary to conduct an effective survey of the engineering geology, hydrogeology, and other contents within the construction area. The survey work is not only an important part of the early stage of engineering construction for engineering management personnel, but also an important factor in ensuring safety and stability during the construction process. Therefore, in order to effectively avoid various geological risks during the construction process or after the completion of the building, the preliminary engineering geological survey work is of great significance. In the process of engineering geological exploration, hydrogeological issues are also important exploration projects. This article will explore and study hydrogeological issues, analyze the water physical properties of rock and soil, and the impact of hydrogeological issues on the project, and then propose effective measures to do well in engineering geological exploration.

In the process of teaching and learning at any stage, the important role of interest guidance cannot be ignored. Especially in college mathematics teaching, mathematical knowledge is very complex and abstract, and most students are unable to effectively understand and master it during the learning process. So it is even more important to fully stimulate students' interest in learning. This article analyzes the significance and current situation of stimulating students' learning interest in university mathematics teaching, and conducts effective strategy analysis. In order to effectively awaken students' desire for knowledge, guide students to change from passive learning to active learning, so that students can continue to grow and progress in this process.
