[誤] Nowadays as more and more people study abroad, the overseas students are not so popular as before.
[正] Nowadays as more and more people study abroad, the returnees are not so popular as before.
注:“海龜(歸)派”是指那些在國外留學以后又回來的人,是個非常形象的新名詞。但overseas student 是指正在國外學習的“留學生”,意思正好相反,所以要換成 returnee。這個詞本身就包含在海外學習過的意思。
