小學生 的英文怎麼說?

[1] a student in primary school[2] an elementary school student[3] a student in elementary school[4] a primary school student[5] schoolboy
  schoolgirl

elementary school 跟 primary school 是「小學」的正統說法，所以「小學生」可說 a student in primary school 或 an elementary school student。

schoolboy 跟 schoolgirl 指上學的小男孩或小女孩，意思較不明確，但大部分人會想到是指小學生。
