How time flies! I have studied in my school for three years. And I will

graduate from middle school in a month. I am eager to share my happiness and

sadness with you. I had so many memories in three years’ life. One of them

impressed me very much. I still remember, when I began to learn English, I found

it too difficult. No matter how hard I tried, I still couldn’t do well in it and

almost gave it up. As soon as my English teacher found my problem, she had a

talk with me about how to learn English well. Since then, she has kept helping

me. Little by little, I’ve become interested in English and I’m good at it. I

think I am so lucky to become one of her students. I’ve learned a lot from her.

I will try to help others when they are in trouble. I think it is a happy thing

篇2:《诺贝尔》读后感550字

全文共 579 字

今天我读了一篇介绍诺贝尔的文章。文章讲述了诺贝尔的成功经历:诺贝尔的一生在机械、化学方面有过许多发明,而他最突出的发明是炸药。诺贝尔小时候就想发明出一种东西帮助开路工人劈开大山,为了实现这个想法,诺贝尔就一直把兴趣放在了研究炸药。他首先发明了一种液体炸药,但是不安全,炸药在运输途中容易爆炸。于是,诺贝尔又开始了新的发明,反复试验,在实验过程中,他的弟弟被炸死了,父亲也残疾了。但诺贝尔没有气馁,租了一条大船搞实验。在他的不懈努力下,安全的炸药发明出来了,可它的威力不够大,诺贝尔又开始琢磨、研究、试验,经过无数次的失败,诺贝尔终于成功了!

是坚持不懈换来了诺贝尔的成功。如果第一次他放弃了,就不会有安全的炸药了,那就更不会有后来的安全、威力强大的炸药了。我们学习也是一样,只要坚持就会胜利。我刚开始学古筝的时候简单,我觉得好玩还能坚持练琴。可是,慢慢地学得多了,也越来越难了,考级的要求也也来越高了,一天不练琴就觉得手指僵僵的不听使唤,有时我也想放弃不学古筝了。可是,在妈妈的鼓励下,我也给自己鼓劲:我都已经学到这份上了,不能打退堂鼓呀,坚持就是胜利!我忍一忍,坚持练琴,就这样,我一直学了下去,成功考过了十级。更值得高兴的是我在很多比赛中获金奖、银奖!

读了诺贝尔的故事,更加坚定了我的信念:成功的秘诀就在于坚持不懈。只要别把前进的脚步停下,成功一定会到来!
