如果您想用英语表达她学习很好的意思，可以说："She is a good student." 或者 "She excels in her studies." 这个短语来源于英语中对学习能力优秀的人的描述。例如：

"I've always been impressed by how well she does in school." (我一直都很佩服她在学校里的表现。)

"She's a straight-A student who always gets top marks in her exams." (她是一个全A学生，考试总是拿到满分。)

"He's so smart and always gets the best grades in his class." (他很聪明，班上总是成绩最好的。)
