这两周我们进行了期中测试，并进行了讲解，其中很多同学的成绩有了进步，但

In the past two weeks, we conducted a mid-term test and gave an explanation. Many of the students have improved in their grades, but there are still some students whose grades are worrying, and we hope to attract attention. We have completed the study of similar triangles. Starting next week, we will study the second volume of the ninth grade. We hope to prepare our own textbooks, thank you!
