選B.pursue在此意為“追求”,是及物動(dòng)詞,后＋名詞（their own intrests）作其賓語,“追求他們的興趣”.
C項(xiàng)persist意為”堅(jiān)持”,是不及物動(dòng)詞,后不能直接加賓語,其搭配為“persist in （doing）sth或 persist with sth.
D項(xiàng)proceed,意為“繼續(xù)做”,也是不及物動(dòng)詞,搭配為“proceed with sth 或proceed to do sth.
雖然C、D的意思對(duì),但是語法不對(duì),只有B是及物動(dòng)詞,后能直接加賓語.故選B
整句話可翻譯為“學(xué)生不僅應(yīng)當(dāng)做好功課,也應(yīng)當(dāng)追求他們的興趣”
