some university offer online courses though i doubt if they offer any English Literature courses. Not trying to baffle you, it's not just Shakespeares English majors learn, it's a lot more complex than that. You could try talking to a Chinese major to get an idea of the level of complexity. Middle English, 16th, 17th, 18th, 19th, Renaissance, Restoration, Victorian, Modern, Post-Modern, British, American, Canadian, diaspora, world lit., etc., are frankly not designed for you. English classes don't just read the literature, they are designed to study, analyze at a great in-depth. Close reading is probably not something to be developed by ESL students.
If you are just curious what they read, you could try finding a list of English lit. complied by 复旦大学。
For high school courses, that depends, hard to pigeon hole, but basically any combination of prose, poetry and drama, an intro/survey level.
