| PAST TENSE | |
|---|---|
Past tense focuses on an event or a series of events. No particular importance is placed on timing. The events are reported in the sequence (order) that they happened. |
|
| FIRST EVENT | SECOND EVENT |
First, I stopped at an ATM. |
Then I took my friends out to lunch. |
First, I took my friends to lunch. |
Then I stopped at an ATM. |
First, we sat down. |
Then the waiter tripped and dropped his tray on our table. |
First, we stood up to leave. |
Then the waiter tripped and dropped his tray on our table. |
| PAST PERFECT TENSE | |
|---|---|
Past perfect contrasts the timing of two events and places emphasis on the timing of the first event which has an effect on the second event. "good or bad timing" |
|
| EARLIER EVENT | LATER EVENT |
I had stopped at an ATM |
before I took my friends out to lunch. (good timing) |
I had taken my friends to lunch |
before I stopped at an ATM. (bad timing) |
We had just sat down |
when the waiter tripped and dropped his tray on our table. (bad timing) |
We had just stood up to leave |
when the waiter tripped and dropped his tray on our table. (good timing.) |
The difference in time often indicates "good timing" a fortunate sequence or "bad timing" an unfortunate sequence.
| LATER EVENT | EARLIER EVENT | ||
|---|---|---|---|
Before is optionally used with a past perfect sentence to emphasize which action happened first. |
After is optionally used with a past perfect sentence to emphasize which action happened second. After introduces the earlier event. |

the war started. |

| ESL DESCRIPTION | LINGUISTIC DESCRIPTION |
|---|---|
In traditional grammar, while, when, before, after, and since may be used to introduce a "time-related" clause. These words belong to the conjunction category. The "time-related clause" is called an adverbial clause: it tells When? |
In current linguistic analysis – while, when, before, after, and since — belong to the category preposition, which can take a clause as a complement. (In traditional grammar, a preposition is followed by an object.) |
Azar & Hagen call these adverbial clauses or "time clauses" with no mention of a term for the connector. (UUEG 4-3, Adverb clauses 17-2; Reduction 18-1) |
Huddleston & Pullum (2009) have re-assigned a large number of items previously analyzed as adverbs after, as, as soon as, before, once, since while, and when to the class of prepositions. The preposition is the head of the prepositional phrase (PP) which can be complemented by a noun phrase or a clause. (CaGEL 612-7) |
Swan (2009) refers to while, when, before, after, and since as conjunctions. (Swan 30.1) |
Quirk & Greenbaum (1989) place while, when, before, after, and since in the class of conjunction. They function as subordinators of adjunct clauses that express time-relationship. (CoGEL 8.53) |

One summer when I was eleven, my family had the money and the time to take our first vacation. My father, my mother, my younger sister and I got into my father's '54 Ford to go to Cordoba where my parents rented a house up in the hills. Cordoba is a city that is famous for its mountains and rivers and is located 900 miles away from Buenos Aires where we lived. After we drove a long time, we had arrived there.
My father wanted to capture everything in pictures, the scenery, the family and the car. The problem was that he wanted everything together in each picture. One morning, after breakfast it was a the perfect time for a picture with the car, the family, the house and also the scenery, all in one shot. In spite of the fact that it was almost impossible he decided to try his best. First, he made us get closer to the car, it didn't work because the scenery was gone. Second, it was time for him to go down the hill, it didn't work either because he couldn't see the car. Finally, he had the great idea of moving the car to the front.
Since he didn't have the keys with him, he decided to push the car down. He gave my mother a rock to put under the car wheel to stop it when it was in right position for the picture. Despite my mother's effort to put the rock in the right place, my sister's open eyes and my open mouth, the car went over the rock and rolled down the hill.
My mother ran into the house crying. The three of us started walking down the hill looking at the car which stopped on the bottom of hill with the front up. I remember thinking "how we are going back home?". When we got to the bottom of the hill, to our surprise, the car was intact. The two front wheels were up on two big rocks as if somebody place them there on purpose. We were so happy! My sister and I ran up the hill to gave my mother the news. My father staring at the car was saying "One more thing to tell our grandchildren."
capture – keep, save, take
intact – together, not broken
scenery – the land and trees, the view
