Thank you very much. I need to wrie instructions of an MP3 player, a video recorder and a CD-player. Could you help me? I included a few more sentences.

1) I must be silent during teachers' explanations. I hang the clothes in the sun so that they get dried sooner (?? or more quickly?)
2) At school I must listen to the teacher, listen silently to the oral tests,take notes when my classmates or teacher speak (are speaking).
3) I mustn't interrupt the teacher when she or he is speaking, write on my books.
4) I put the washing powder (soap, but not fluid) in (or into?) the washing machine.
5) When the washing is finished
Trinculo overhears Caliban's conversation about killing Prospero and reports it to Prospero.
6) What's the weather forecast for tomorrow like?
It's going to be scorching hot.
It's going to be muggy (with a temperature over 35 degrees Centrigades)
7) We had a flood (?) in 1994 since the river burst its banks.
He speaks good English because he was brought up (or grew up?) in England.

1. You still need to complete the comparison: sooner than when? more quickly than what?

2. ... tests, and take ...

3. ... speaking, or write ...

4. washing powder, detergent - either term works. The detergent I use, however is liquid!!

5. - incomplete thought: "When the washing is finished"

7. I'd change "since" to "when"

All else is fine.
