This document provides information on the proper use of the prepositions "for", "during", and "while" followed by examples. It explains that "for" indicates a period of time, "during" is used before a noun to refer to an event or activity, and "while" refers to two simultaneous actions or events. The document includes an exercise for students to practice using these prepositions correctly in sentences. It aims to evaluate whether the presentation helped improve students' knowledge of the differences between these three common time prepositions.

2. THE USE OF FOR, DURING AND WHILE
The prepositions during, for, and while are often used with time expressions. Let's take a
look at the difference in usage between during, for, and while.
How to use for?
For is a preposition which is used with a period to say how long something goes on, It
answers the question : How long?
for twenty minutes for a week for a long time for a year
For example:
"Simon has been sleeping for 8 hours."
"We waited for 30 minutes outside your house."
How to use during
During is a preposition which is used before a noun (during + noun) It means 'throughout
the period' or 'in the course of' an action or event. For example:
during the match during the war during the weekend
I fell asleep during the film because it was so boring. (The sleeping happened at the same
time as the film.)
Notice that during is followed by a noun, which often represents an activity (during + the
film).
"Nobody spoke during the presentation."
“The bank was robbed during the night”
Remember: You cannot use during to say how long something continues.
Incorrect= It snowed during 3 nights correct = It snowed for 3 nights

3. How to use while
While is used to talk about two things that are happening at the same time. The length of
time is not important. It is very similar to during, but it is followed by a sentence (while +
subject + verb...), so they are not interchangeable. For example:
Stan: When did you lose your credit cards?
Mark: I think it was while I was shopping in El Corte Inglés.
"The phone rang while I was watching TV."
"I met him while we were studying in the library."
It is often possible to drop subject + be :
“I generally listen to music while driving to work.”
“Sam twisted his ankle while playing tennis.”
While can also be a noun which means 'a period of time'.
“I spoke to the neighbor for quite a while yesterday.”
“It's been a while since I read that book.”
