复读一年用英语怎么说

"Repeating a year" in English is commonly referred to as "repeating a grade" or "being held back a grade." The phrase likely originates from the practice of making a student repeat the same grade level in school if they have not met the necessary academic requirements to move on to the next grade.
Examples:
"John was held back a grade because he didn't pass the final exam."
"Sara is repeating the fourth grade because her reading skills are not up to par."
"The school board decided to retain Jane in the third grade due to her poor performance in math."
中文翻译：
"John因为没有通过期末考试，所以被留级了。"
"Sara因为阅读能力不足，所以要重读4年级。"
"学校董事会决定因为Jane在数学方面表现不佳，让她重读3年级。"
