我希望我在高中能学好英语。但我认为那很难实现。请在帮我翻译这几句

My grades for english are a disaster. Since my desk mate has a really long self-introduction, i will end mine sooner.

My English is very bad. Because of my classmates have a very long self-introduction, so I introduce myself first ended.

My English is very terrible.Because my deskmate has a very detailed self-introduction,let's skip my introduction.
补充的:
I hope I can improve my English in High School,but I think it is very hard to come true.
That's it.Thank you.作为结语

介绍在哪?
