求写人生中最快乐的一段时光为题英语作文,要水平高一的

If you ask me something about my happiest time,I'll answer like this.
I don't know exactly about my happiest time,because every day I'm living is the happiest time for me.I always keep a good mood.Every day I'm happy at work.When I'm at work,I always do my best,so my boss is satisfied with me.I get on well with my colleagues as well,since I'm always willing to help them.No wonder I have so many friends.That is to say,I am happy when I am working.
What's more,my best friends Phillip and Oscar always speak English with me.Every time,they bring me a very big surprise.They help me a lot.Thanks to their help,my oral English is getting better and better.I don't know how to appreciate them.Keeping learning makes me happy,too.
