When sprinting for CET-4, the teacher arranged for us to recite three sentences in the morning, and only three sentences were read by someone. But as soon as he didn't bring it, we didn't read it, let alone give us the same rules as the task. . . . 800 sentences, the first three days may be ok, but the following is not to do the same thing over and over again. If you have such strong willpower, you can also recite the word book every day. Judging from your question, you have doubts in your heart. You may not be the super-academic type who insists on it every day (say whatever you want and do it without hesitation).
Suggest less, learning English is a persistent process. It may be better to connect words with sentences. Don't worry, step by step, the English teacher should have told you the relevant methods, just do what she says. A day doesn't have to have much capacity, as long as it can be repeated every day, the harvest will be great. . . PS: In this era, babies who learn English can't afford to get hurt, especially under our educational model.
The above is my personal opinion, hoping to help you.
