You were sleepy when you were writing your paper. There are two possibilities. First, it has nothing to do with writing a paper. You are very tired, weak and malnourished these days. Take a rest before you write. Secondly, I find it difficult, because I have no clue in writing my thesis. I felt sleepy when I sat there. I'll provide you with a channel. Don't rush to write. You can't write if you sit there. Computers are very convenient now. It is worth learning to go there and read papers related to yourself; Find another colleague and discuss what you mainly want to discuss, what to write first and then what to write, and what to write in the key part; In the key part, whose famous words should be cited to improve the grade of the paper, and what examples should be cited to prove it, such as ancient sages, contemporary celebrities, or their own life income. After collecting the required materials, think again before adopting any argument method that best represents your national thinking, and you will be ready, and then you will not have a headache and can't sleep.
