[誤] The game is at hand and every athlete is training hard to improve their previous records.
[正] The game is at hand and every athlete is training hard to improve on their previous records.
注:improve 指“改善,提高”,如 improve one\'s language ability(提高某人的語言能力)。在英國人看來,以前的紀錄(previous records)是既成事實,不可能再加以改變(improve)了,所以應該在 improve 后面加上介詞 on,以表示創(chuàng)造新的、更高的紀錄。
