Simple Past Tense
|
The simple past tense is sometimes called the preterite tense. We can use several tenses to talk about the past, but the simple past tense is the one we use most often.
Howdo we make the Simple Past Tense?
To make the simple past tense, we use:
* past form only
or
* auxiliary did + base form
Here you can see examples of the past form and base form forirregular verbs and regular verbs:
  | V1
base | V2
past | V3
past participle |   |
regular verb | work
explode
like | worked
exploded
liked | worked
exploded
liked | The past form for allregular verbs ends in -ed. |
irregular verb | go
see
sing | went
saw
sang | gone
seen
sung | The past form for irregular verbs is variable. You need to learn it by heart. |

The structure for positive sentences in the simple past tense is:
subject | + | main verb |
  |  | past |
The structure for negative sentences in the simple past tense is:
subject | + | auxiliary verb | + | not | + | main verb |

The structure for question sentencesin the simple past tense is:
auxiliary verb | + | subject | + | main verb |
did |   |   |   | base |

  | subject | auxiliary verb |   | main verb |   |
+ | I |   |   | went | to school.|
| You |   |   | worked | very hard. |
- | She | did | not | go | with me. |
| We | did | not | work | yesterday. |
? | Did | you |   | go | to London? |
| Did | they |   | work | athome? |
Exception! The verb to be is different. We conjugate the verb to be (I was, you were, he/she/it was, we were, they were); and we do not use an auxiliary for negative and question sentences. To...
