请大家帮我找找错，再顺便帮我填几句，我想不出来还要写什么了，帮帮忙呀！！
从第二句开始，你就用错了，典型的中文式英语，应该用：It is very hot.还有，你后面两句用过去时态可以，但你要标明时间状语啊，比如说，this morning之类的，第五句，又是中文式英语，只要用：He is very kind就可以了，还有最重要的一点是，你要用过去式就用在一起，不要交错，这样的话，作文会很低分的。
Today was Sunny.The weather was very hot.I got up very early.My cousin came to my home.He is a very kind person.We enjoyed ourselves.He gave me a gift.It was a lovely doll.I like it very much.And then he said goodbye to us.
你写的是今天 那就用现在时态 干嘛后面都用过去时态
