英文 自我介绍 Hello,teachersMy name is ____,I'm seventeen years ol

I love Maths and I'm good at Maths.改成 I'm good at Maths and i love it比较好吧
I am outgoing and have lots of friends改成I am outgoing and i have lots of friends.and前后要保持一致 前面是句子所以后面也要连接一个句子.
.I like reading English books ,also like listening to English songs改成.I like reading English books and listening to English songs.逗号不能连接2个句子,所以.I like reading English books ,also like listening to English songs是一句话 但是一句话里面不能有2个谓语动词所以把also like去掉 用and连接就可以了.
Thank for listening.改成Thank you for your listening.
语病就这些 可是这篇自我介绍看起来有点僵硬 所以我修改了一下
Hello,teachers
It's my pleasure for me to stand here and make a introduction about myself .My name is ____,I'm seventeen years old,After three years ,now I will graduate from ______ Secondry School this summer.i am really excited.I am outgoing and i have lots of friends.I love chatting with my friends during the break.In my spare time,I love listening to music or chatting with my friends online.As for my study,I'm good at Maths and i love it .I am also good at English.I like reading English books and listening to English songs.At last ,i believe I will work hard in ________High School.Thank you for your listening.

最好开头用Good morning/afternoon.
第三行第二个maths可改为it。.I am outgoing and have lots of friends这里不能省略I.
第四行，enjoy代替love会好一些。or 改成and
第五行.I like reading English books ,also like listening to English ...

没错，英语不错

拙见
i like reading english books and listening to english songs,
thank you for your time.或者thank for your attention.
总体来讲还是写得很流畅的，英文功底不错。

the summer之前不用介词吗？外向好像还有其它词
