假如你是tom,请用英语给你的朋友jim写封信,告诉他你和全班同学上星期天去海底世界参观活动的情况,80词

Dear Jim,
Hello.How are you lately?I am writing to tell you about me.Last Sunday,Our class had an activity.We went to the Sea World.Early that morning,we gathered at the school gate.We went by bus.We set out at 8:30am and got there at 9:00am.There were many people,most of whom were students at the Sea World.We saw many fish that we had never seen before.They were all intereting,swimming here and there in the water.They have different colours and different sizes.To our delight,we saw a shark.It was very big.All other fish dared not approach it.
We really had a good time at the Sea World.
Regards
Yours
Tom
