Question

帮忙修改一下演讲稿，看看有没有语法错误，和用词不当的地方，谢谢。

Hello! Everybody! I study in No.1 Middle School. My name is Yangzi.
How did you spend your last weekend? Fun, huh? Well, on Saturday morning, I went to my grandma’s home .She was very kind to me, and she cooked a nice meal for me. In the afternoon, I had a piano class, it was very interesting. And in the evening, I went to a movie with my parents. But on Sunday, I started to do my homework. I had too much homework to do. And I had to study for the coming test. After studying all day, I felt very tired.
So, the weekend was tired but interesting.
Thank you.

有个小问题，就是英语和汉语不同，很多地方不要逗号，不过你是演讲，就不碍事，以后写作文是要注意。
稍微调整了一下语序，你的时间状语都是一个模式，会显得重复。都是简单句，没有什么语法错误，就是最后"the weekend was tired but interesting"的tired有问题，应该用"令人感到劳累的"tiring

1.in the afternoon 可以该成 that afternoone
2,tired 只能修饰人的心情而不能说 the weekend was tired.可以改成 tiresome,令人劳累的

提一点建议，以后不管是写文章或是演讲稿，记得多用连接词，从句以及一些固定句型，这样不但会增加文章的连贯性也能使你的文章增色不少。下面的修改供你参考。
