Thank you very much for your corrections. Here are some more sentences I'm unsure of.
1)The monster is an outcast, a rebel uncorrupted by society. He is different from anyone (else?) because of his ugly (revolting?) aspect. He becomes a murderer who kills even a child.
2) The monster created by Dr. Frankenstein stands for the dark side of the doctor (doctor's personality), the result of his desire to overcome the limits of science that leads (???) to feelings of horror and disgust.
3) His watery eyes are dull-yellow and set in grey sockets. He has shiny black hair and pearly white teeth in contrast (better: which contrast) with his terrible aspect.
4) The story starts and ends in a desolate place of the artic regions. Frankenstein makes his experiment in a desolate laboratory with limbs (using limbs) of dead bodies.
5) The monster himself remains for a long time in a cottage. (He is confined in a cottage when he learn the ways of humans?)

2) The monster created by Dr. Frankenstein represents the dark side of the doctor's personality, the result of his desire to overcome the limits of science, limits that lead to his feelings of horror and disgust. (I just guessed at what "that" is referring to. Let me know if I didn't guess right. PS -- your reader shouldn't have to guess!)
3) His watery eyes are dull-yellow and set in grey sockets. He has shiny black hair and pearly white teeth, which contrast with his terrible looks.
4) The story starts and ends in a desolate part of the Arctic regions. Frankenstein makes his experiment in a desolate laboratory with using limbs of dead bodies. (One of those instances of "desolate" needs to be replaced -- which one will you change? to what?)
5) The monster himself is confined for a long time in a cottage once he learns the ways of humans.
Again, compare carefully.
