请英语高手帮忙看下我的英文信有语法错误吗?

改正如下
Dear Trine,
（人名不可以首字母小写,永远要大写）
I hope you had a nice Labor Day.Thank you very much for the reply.
Regarding your questions:
This is the second year of postgraduate study.I have come to the end of the courses and got all the credits.Now,I am working on some projects and about to work on my thesis paper.My graduation will be December this year or June next year,to be decided by the completion date of the thesis paper.
If I have the opportunity to be part of the exchange program,I will choose to work on some projects.I learned from my friends that there is an ongoing safety project at HIT,and if possible I would also like to be a part of it.This is because safety and risks are part of my thesis paper.I plan to spend three months in Norway,and finish my dissertation at the same time.I also want to have an academic paper published.You can bet that I will try my best and to take full use of this opportunity.
If there are no suitable projects,to study in Norway would still be a good choice.I can choose the fall semester courses,and then graduate in June next year.I am more interested in biological （不知道这里为什么要用一个形容词,是不是想说biology?）,risks and CO2.I am very eager to experience life and study in Norway to learn some courses from different national programs.But I do not know the arrangements for the autumn,so could you please give me a second semester ‘s curriculum?
After the weekend,I will contact Ms Huang at the International Office as soon as possible to obtain more information.If the opportunity is appropriate,I will prepare the official transcripts in time.(Including the certificate of master's degree studies and bachelor's degree,etc.)
Kind regards,
