英语有没有错?
Good judges!IMy name is ChenZhen,the topic of my presentation is:Never give up
We will encounter difficulties.Do you give up because of the difficulties?Do you give up because of frustration?Is it because you do not give up smoothly?Sandoz - that is,the founder of Kentucky Fried Chicken,fried chicken was invented,he rejected the 1009 meeting; Edison has experienced repeated failure of 6000 was the invention of light bulbs; Helen.Keller blind and deaf in the case of completed .studies at Harvard University because they did not give up when there is any frustration,to a successful end.There is a saying which goes like this:God is a person behind closed doors at the same time,it must for him to open a window.As long as we do not give up,continue to work hard,you can leave the closed door,to open the windows,to success,to glory!Thanks
急
评委好！我叫陈镇，我演讲的题目是：永远不要放弃
大家都会遇到困难。您是否因为困难而放弃？您是否因为挫折而放弃？您是否因为做事不顺利而放弃？山德士--也就是肯德基的创始人，他发明的炸鸡被拒绝了1009次；爱迪生经历了6000多次的失败才发明了灯泡；海伦.凯勒在又盲又聋的情况下完成了哈佛大学的学业......因为他们遇到挫折时没有放弃，最后都走向了成功。有一句话是这样的：上帝在为一个人关上门的同时，一定为他开了一扇窗。只要我们不放弃，继续努力，就能离开关闭的门，走向打开的窗，走向成功，走向辉煌！
