Dear Mr. Johnson, I am writing to ask for your guidance because I have been struggling to improve my English grades this semester. First, I find it quite hard to understand long reading passages and remember new vocabulary, which significantly lowers my test scores. However, I am fully willing to put in extra effort, so I would appreciate it if you could recommend some effective study methods or practice materials. In addition, if possible, could you please suggest some after-class resources, such as podcasts or graded readers, that match my current level? Thank you very much for your time and support, and I sincerely hope to receive your detailed suggestions soon.
