1) What do you think about going to the cinema?
How about meeting at school?
2) How do I arrive at the school?
I put the clothes back in the wardrobe.
I put (is "take") the rubbish out once a day.
3) I must have all books for lessons (I must bring all my school books to class?)
4) I mustn't drop anything on the floor.
I must pay attention during lessons/school hours.
I mustn't bring my schoolbag into the labs.
5) When I go into the labs, I mustn't bring my schoolbag.
I mustn't leave the classroom if the teacher doesn't give us permission.
6) I mustn't run in the corridor or in class.
7) I must always bring my books to school.
Is Oxford Street the road near the underground/tube?
8) I usually hang the clothes in the sun so they get dried earlier.

2. Either "put" or "take" works fine.

3. The sentence in parentheses is better.

5. ... if the teacher doesn't give me permission.

8. "earlier" than what?

All else is fine.
