Looking back on my last midterm exam, after suffering through the monthly exams, I worked extra hard. I spent much time solving problems and reviewing, hoping to prove my abilities through this exam.

As the saying goes, "Failure is the mother of success." This is absolutely true; By finding lessons in failure and working harder next time, one will surely succeed.
Thomas Edison is a world-famous inventor, but we often only see his achievements and not the countless failures and efforts behind them. For example, he failed over 8,000 times while inventing the light bulb, but he never gave up. He kept analyzing the causes of failure and making improvements until he finally succeeded.
KFC is also a global favorite, but do you know how many failures Colonel Sanders faced? After retiring from the military, he lived on a meager pension. He wanted to promote his fried chicken recipe but was rejected by countless businesses. However, he never lost heart. After more than 1,000 failures, he finally found a partner and within a year and a half, he had over 300 franchise stores.
The experiences of many great people prove that "failure is the mother of success." After all, without going through the rain, one cannot see the rainbow.

老师常说：“失败是成功之母。”这句话千真万确。从失败中总结经验，下次努力，终能成功。
爱迪生是家喻户晓的发明大王，但人们往往只看到他的伟大成就，却忽略了背后的汗水与教训。例如，他在发明电灯泡的过程中失败了8000多次，但他从未气馁，而是通过不断寻找原因、改进方法，最终取得了成功。
肯德基也是如此，创始人山德士上校在推广炸鸡秘方时，曾遭遇过上千次的拒绝。他曾仅靠微薄的退休金生活，但凭借着不懈的努力，在经历千次失败后终于找到了合作伙伴，短短一年半的时间就拥有了300多家连锁店。
“失败是成功之母”，无数伟人的经历都印证了这句话。不经历风雨，怎见彩虹。
