Introduction:

Refers directly to the question

Shows an understanding of Stanley's character and how his attitudes and
behaviour can be linked to the main themes of the play.

This should be a general introduction to the character of Stanley: detailed
points will be made later on.

He represents the very male, very dominant character of the novel from
his initial appearance...

Character:

Introduce the most obvious points of Stanley's character, referring to
the text.

Discuss the imagery connected to Stanley.

Explain his involvement in the main events of the play. This will include
his subtler and more radical actions.

Explain how Stanley's character and attitudes affect his actions

Explain the consequences Stanley's actions have (the effect upon
the other characters and the development of the plot).

In Scene one, Stanley is seen bringing home a package of raw meat to
Stella. He is the provider, and the association of bringing home meat,
especially raw food, gives him a connection with a predator, a wild animal.

Stanley does not disguise his dislike of Blanche's presence. He
makes her feel uncomfortable, sharply picking up on her alcohol consumption
and actually being quite intuitive when he comments on the effects that
drink can have. His intimidation and to some extent his attraction to
Blanche grow throughout the play.

Stanley is very territorial. This immediately determines his stance towards
Blanche and his desire to be rid of her.

Stanley is very much the centre of his world. His ability to dominate
is seen in all of his relationships.

Conclusion:

Remind yourself of your argument and reinforce this here. You can add
an original point to conclude with, but do not state anything, which you
have not looked at before: you should not introduce totally new ideas
in your conclusion.
