1. Both sentences are correct, but they differ slightly in their intended meaning.

- "Shut the door behind you" is a command or instruction directed at someone else, indicating that they should close the door as they leave.
- "Shut the door behind yourself" is a command or instruction directed at the person being spoken to, emphasizing that they should close the door behind themselves as they leave.

2. Both sentences are grammatically correct, but they have slightly different meanings depending on context.
- "I looked about me" suggests that the speaker is looking around at their surroundings, taking in everything around them. It is a more general expression of observing one's environment.
- "I looked about myself" suggests that the speaker is looking at their own self or body, perhaps examining themselves or checking for something specific. It is a more introspective expression.

3. "We have the whole week before us" is the correct option. This sentence indicates that the entire week lies ahead for the speaker and others. It implies that they have the time and opportunity to accomplish tasks or make plans throughout the week.

4. "I looked at myself in the mirror" is the correct option. This sentence means that the speaker viewed their own reflection in a mirror. "Me" is used as an object pronoun, but when an action is being performed upon oneself, "myself" is the appropriate reflexive pronoun to use.

Overall, the correct choice in each case depends on the intended meaning and the context of the sentence.
