上那么多课外辅导班用英语怎么说

“课外辅导班”在英文中叫做 "after-school tutorial classes" 或 "extracurricular tutorial classes".
"After-school" 意思是 "在学校课程结束后"，"tutorial" 意思是 "辅导"，"classes" 意思是 "课程"。
"Extracurricular" 意思是 "课外的"，这里用来表示这些课程不是学校正式的课程。
例句：
Many students attend after-school tutorial classes to improve their grades.
大多数学生参加课外辅导班来提高成绩。
Extracurricular tutorial classes are becoming increasingly popular among parents and students.
