"When did you read that book?"
We use the Past Simple to talk about complete actions in the past.
Structure:
We will use different forms of the verb depending on each case:
In affirmative, we need to use a verb in past. It can be regular (-ed) or irregular (see the lists below). – "I went to the supermarket yesterday".
In negative, we use the auxiliary didn't , and the simple form of the verb. – "I didn't know that!".
In questions, we need to use the auxiliary "did", and a verb in simple form, too. – "When did you read that book?"
In English there are many regular verbs. These verbs have an "-ed" ending. They follow specific rules for spelling. Check the following example:
I worked
you worked
he / she worked
we worked
you worked
they worked
I lived
you lived
he / she lived
we lived
you lived
they lived
I wanted
you wanted
he / she wanted
we wanted
you wanted
they wanted
1) Most verbs
Add "-ed"
For example:
work - worked
2) Verbs that end in "-e"
Add "-d"
For example:
decide - decided
3) Verbs that end in vowel + "-y"
Add "-ed"
For example:
play - played
4) Verbs that end in consonant + "-y"
Eliminate the "y" and add "-ied"
For example:
cry - cried
5) Verbs that end consonant + vowel + consonant
If the second syllable is stressed, we double the last consonant (except for -y, -w, or -x.)
For example:
prefer - preferred
Many verbs in English are irregular. Fortunately, some verbs are similar to each other, so they are easy to learn. You can check these lists to learn all about irregular verbs!
