6. If the verb ends with consonant + vowel + ‘-l’ , we normally double the final ‘ –l ‘ and add ‘-ed’.

Use and meaning of the past simple tense
Completed action in the past
An action that started and finished at a specific time in the past
Examples:
Last night I watched television.
I played football 3 days ago.
Time expressions used with the past simple
10 minutes ago
4 days ago
3 weeks ago
a month ago
2 years ago
last night
last week
last month
last year
yesterday
Series of completed actions
We use the past simple to list a series of completed actions. We often separate each action with a comma (,). We separate the last action with the word “and”.
Example:
Yesterday I went to London, bought a camera and then took some photographs.
In the above example we used the past simple of the following irregular verbs:
go -> went
buy -> bought
take -> took
Duration in the past
We can use time expressions with the past simple to describe the duration of an action in the past.
“for” + period of time
for three minutes
for two hours
for five days
for a fortnight (“a fortnight” means two weeks)
for two months
Example:
Sarah and David talked for two hours.
“all” + unit of time (in the singular form)
all day
all night
all morning
all afternoon
all evening
“all” followed by a unit of time describes an action whose duration lasts for the whole period of time, from the start of the unit of time until the end.
Note that the unit of time is always in the singular form.
Example:
Mark waited all morning.
This means that Mark started to wait at the beginning of the morning. He stopped waiting at the end of the morning. He waited for the whole of the morning.
When clauses with the past simple
If we have 2 clauses in the past simple, the “when clause” happens BEFORE the main clause (in time)
But we can write the 2 clauses in any order.
For example. Here is a list of 2 actions in the past. 
1)Mark woke up
2)Mark shaved
We can write this in 2 ways:
Mark shaved when he woke up.
or
When Mark woke up, he shaved.
The meaning of both sentences is the same and both sentences are correct.
If we write the “when clause” first, we separate it from the second clause with a comma (,)
