***** NOT A TEACHER *****
(1) Yes, the verb "wish" can be confusing.
(2) And sometimes we must use the verb "hope" -- not "wish."
(3) Please remember that "wish" many times refers to something now
or in the past that I cannot change:
I wish that I were handsome. (I will never be handsome)
I wish that everyone were nice. (That will never happen!!!)
I wish that I had eaten only one hamburger yesterday. (I ate three
hamburgers yesterday, and now I am very sick.)
(4) Please remember that "hope" means that MAYBE something will
I hope you get that raise in money at your job.
I hope that Mr. X wins the election next week.
I hope that there is no rain tomorrow. (I want to go to the beach.)
Let's look at your sentences:
1. I wish that I could have worked harder. I think it's fine.
2. I wish that I had studied better. I think it's fine.
3. I wish that he would recover soon. In this sentence, I think
most teachers would suggest "hope":
I hope that he recoverS soon.
4. I wish that I could sleep early. I do not understand exactly what
the meaning is. Do you wish to say something like:
I wish that I could go to bed earlier. (I have to work until 10 p.m. I never
get to bed until 11:30 p. m.)
5. By the way, the word "that" is not necessary in those sentences:
I wish (that) there were peace in the world.
Since you are a learner, I respectfully suggest that you use "that."

P. S. Please ask any more questions that you have about this
matter. Many people would be happy to answer you.
