I forgot to include the following sentences. I hope you can have a look at them, too.

1) 1984 can be considered an anti-utopian novel, which shows Orwell's sympathy for all the people who were murdered and exhiliated in totalitarian dictatorships (?) in the first half of the 20th century.
2) People are kept in poverty by the war, which is used by the state as an instrument to frighten the masses. Moreover, the state uses propaganda because, in this way, people think to be living in luxury (?).
3) He learnt first hand what it meant being poor.
4)Also linked to the theme of the double, is the author’s fascination with the beast in man.
5) This is obviously represented in his creation of Hyde who is described throughout by others in terms of animal imagery.
6) When Utterson confronts him he is described as “hissing” like a cornered snake. He is described as a “thing” which cries out “like a rat”; he moves like a monkey and screams in “mere animal terror”.

1) 1984 can be considered an anti-utopian novel because it shows Orwell's sympathy for all the people who were murdered and exiled by totalitarian dictatorships in the first half of the 20th century.

2) People are kept in poverty by the war, which is used by the state as an instrument to frighten the masses. Moreover, the state uses propaganda because, in this way, people think they are living in luxury.

3) He learned first hand what it meant to be poor.

4) Also linked to the theme of the double is the author’s fascination with the beast in man.

5) This is clearly demonstrated in his creation of Hyde, who is described throughout in terms of animal imagery.

6) When Utterson confronts him he is described as hissing like a cornered snake. He is characterized as a thing which cries out "like a rat"; he moves like a monkey and screams in sheer "animal terror". [If those words are quoted from the book, then they're fine. If, however, they are in quotation marks for any other reason, then delete the quotation marks.]

Sure! Here's a review and feedback on the additional sentences you provided:

1) The sentence seems fine, but there is a minor typo: "exhiliated" should be "exiled." The sentence is clear and explains that George Orwell's novel, 1984, can be seen as an anti-utopian novel reflecting his sympathy for people who suffered under totalitarian dictatorships during the first half of the 20th century.

2) The sentence has some grammatical errors. A more accurate rephrasing could be: "The state uses the war as a tool to keep people impoverished and to instill fear in the masses. Additionally, propaganda is employed by the state to create a false perception of luxury among the people."

3) The sentence could be rephrased for clarity: "He experienced firsthand what it means to be poor." This sentence states that the person mentioned had personal experience living in poverty.

4) The sentence seems fine and coherent, expressing that the author of the text has a fascination with the theme of the duality of humans.

5) The sentence seems clear and relevant, indicating that the author's exploration of the theme of the dual nature of humans is apparent in his creation of the character Hyde, who is often described using animal imagery by other characters.

6) The provided sentences have several mistakes. Here's a revised version: "During Utterson's confrontation with Hyde, Hyde is described as 'hissing' like a cornered snake. Others also refer to him as a 'thing' that cries out 'like a rat.' He moves like a monkey and screams in 'mere animal terror.'" These sentences describe how Hyde's behavior and mannerisms are described using animalistic metaphors.

Overall, the additional sentences you provided contain some minor errors, but with a few revisions, they can be improved for better clarity and accuracy.
