Final Summary: Tense Decision Tree

Summary Level 5

Quick Tense Decision Tree

When facing a verb blank, ask these questions in order.

Is there a finished past time marker?

Examples: yesterday, ago, last year, in 2015.

If yes, use Simple Past.

Is one action ongoing while another happens?

Use Continuous for the longer background action. Use Simple for the sudden interrupting action.

Does the sentence connect the past to the present?

If the focus is completion or result, use Present Perfect. If the focus is duration, use Present Perfect Continuous.

Is there a normal sequence of completed past actions?

Example: First I woke up, then I ate.

Use Simple Past for both actions.

Did one past action happen before another past action?

Use Past Perfect for the earlier action. Use Simple Past for the later action.

Summary: The 3-Step Elimination Method

Summary Level 5

The 3-Step Preposition Elimination Method

When facing a preposition blank, run this mental checklist in order to eliminate distractors quickly.

Check for fixed collocations and idioms

Does the preceding verb, noun, or adjective strictly demand a specific preposition?
Is the phrase a known idiom or phrasal verb?
Example: "accused __" $\to$ must be of. Eliminate for, with, by.

Check time/place geometry

Apply the Golden Triangle. Is the reference broad (in), specific (on), or an exact point (at)?
Example: "__ 5th May" $\to$ specific date $\to$ on.
Example: "__ sunrise" $\to$ exact point $\to$ at.

Check movement vs rest

Look at the verb. Does the action cross a physical boundary?
If yes $\to$ use into or onto.
If no, because it is a static position $\to$ use in or on.

Final sanity check

Read the completed sentence mentally. Does the logical relationship hold? Agent vs instrument, cause vs effect, point vs duration, possession vs location. If yes, lock it in.
