日记如果要记的是自己从书本上看到的或从人家那里听到的一个知识，只要写下这个知识的要点，那篇幅就可以短些。总之，只要把该记的写清楚就可以了，可短的不要勉强拉长，可长的不要硬缩短。

KNOWLEDGE IS POWER
知识就是力量
If we have no knowledge, we cannot succeed in doing any work. Why? Because knowledge is power. With knowledge we have conquered nature and invented steamers, trains and airplanes. We can send messages by telegram. We can talk with our friends by telephone.
As is well known, we students are the future masters of the nation. She (It) needs us very much. If we do not make efforts to acquire knowledge, how can we render service to her (it)?
如果我们没有知识，我们就不能做成功任何事情。为什么?因为知识就是力量。冯藉知识我们征服了大自然，并且发明了轮船，火车与飞机。我们能用电报传递消息。我们能用电话和朋友谈话。
如众所周知，我们学生都是国家未来的主人翁。她非常需要我们。如果我们不努力去获得知识，将来如何来报效她呢?

英语日记大全优秀范文三：
Last week I saw a young man giving up his seat to a woman with a baby in her arms on a bus. To my great surprise， the woman did not thank the young man; on the contrary， she glared at him coldly， which made him embarrassed.
This incident set me thinking. If everyone acted like that woman， who would like to help others? And what would our society be like?
If anyone gives you a hand， you should express your sincere gratitude to him or her. Only in this way will everyone be ready to help others and feel satisfied with it.
英语日记大全优秀范文四：
This afternoon we had a PE lesson. Our teacher taught us to practise the long jump. When the bell rang, we gathered on the playground. After warming-up exercises, the teacher told us the way of long jump and showed us how to do it. Then we followed the teacher and practised one after another. Soon came my turn, but I felt a hit nervous. Though I failed the first time, yet I didn‘t lose my heart. I kept on practising. At last I was able to jump over 3 meters.
From this lesson I came to see that one will succeed if he has perseverance.
今天下午我们有体育课，老师教我们练习跳远。铃响后，我们.就在操场集合。准备活动完后，老师告诉我们跳远的方法并做了示范，然后我们就跟着老师一个一个地练习。不久，轮到我了,但我感到有点紧张。虽然第一次失败了，但我没灰心，继续坚持练。最后我终于跳过了3米。
从这节体育课中我深刻地体会到一个道理：做任何事情只要有恒心就一定能成功。
