My vacation
I had a scary but interesting summer vacation.My parents and I went to Hainan by plane.It was very fast.After getting there,the weather is hot,and a number of people were wore shoes and T-shirt.
The first day,we went to a restaurant and ate some seafood like fish,octopus.They were delicious.
On the second day,the weather still hot.We went to the sea.My parents went swimming .But I went diving in the sea and played the beach volleyball.We were tired but happy.Then we went to the hotel.We played gobang and relaxing there for two hours.After that,we take a ship on the sea,when I looked out of a really shark.I were so scaried that I couldn't move.Luckily,the shark was quickly left.
The third day,my parents and I visited friends.They were very friendly.And they with we went to visited a museum.It was very big.And I saw some kinds of butterflies.They were very beautiful.And I learned a lot of their living habits.We were surprise.
When we there ,time goes quickly.It is time for leaving there.And I think Hainan was a good place to have fun.I hope to go Hainan again.

"坐飞机",一般不用by plane这种说法,这是明显的中国式英语.老外一般用by air.即我和爸妈坐飞机去海南这句改为：my parents and I went to Hainan by air.

fast 不用来形容旅途的快捷,又是中国式英语.你想表达的是坐飞机很快,用it was very quick比较好.
因为天气热这句话,你不能直接放在里面,因为是单独的句子了,你必须加连接词.
改为：After getting there,because of the hot weather,a number of .(去掉and）.
第一天,应该是On the first day,你少了一个on.
fish和octopus之间最好加个and.即：
ate some seafood like fishs and octopus.
 第二天,天气依旧很热.你少了be动词.On the second day ,the weather WAS still hot.
play volleyball,不需要the.paly soccer ,play tennis.球类运动都不要加定冠词.
We played gobang and relaxing there for two hours这句应该改为We played gobang and relaxed there for two hours.
After that,we take a ship on the sea,when I looked out of a really shark这句应该改为we took a ship at sea ,and I founded out a real shark.错误太多,首先take应该是过去式,然后,发现一条鲨鱼用的短语应该是found out ,而不是look out.look out 是小心的意思.最后,真的鲨鱼是real shark,不是really shark ,really不做形容词.
And they with we went to visited a museum.这句改为And they visited a museum with me.去参观博物馆直接用visit就行了,干嘛要用go to visit ,老外不会这么说英语.with me 不能放在they的后面.
And I learned a lot of their living habits应该是learn a lot about their living habits.这里用learn about 更好.
We were surprise这里你想表达我们都震惊了,应该用surprised.不是surprise,这是动词不是形容词.

差不多就这些,简单给你改改,基本每句话都有错,你的英语还需要努力学习.
   全手打,

再问： 能不能具体改改，我期末考要用。还有“the weather is hot,and a number of people were wore shoes and T-shirt.”是不是要改成“ because of the hot weather，a number of people were wore shoes and T-shirt.”？
再答： 这还不具体啊，我每句话都帮你改了哇，你是要我帮你全文改好放进来？你先采纳我的回答吧，我帮你改就是了，两分钟的事儿。
