What should you ask before choosing a verb tense?
First identify the time the sentence refers to. Is the action completed at a past date, habitual, ongoing, earlier than another event, or still in the future? Then identify the perspective. The same duration can describe a job that has ended or one that is ongoing. This relationship determines the tense, rather than translating the French words “depuis” or “pendant” in isolation.
The simple past places an action in a completed past period, such as a purchase made yesterday or a workshop held last week. The present perfect can connect a past event or situation to the present. In our examples, an activity that began earlier and continues now differs from an event dated in a completed past period.
Here, the past perfect places an action before another past action. Do not conclude that every sentence containing two events requires this form. Read what the sentence is intended to make explicit, then check the options actually provided.
| Situation | Learning example | Relationship |
|---|---|---|
| Completed event | We installed the display yesterday. | Dated, completed action |
| Situation still current | She has worked here since 2021. | Past beginning, present continuation |
| Before a past event | They had prepared the room before the guests arrived. | Preparation before arrival |
| Announced event | The technician will visit tomorrow. | Future visit |
Which clue distinguishes the options?
These learning sentences are not a list of official questions or statistically frequent topics. Choose the form, then explain the timeline.
The team _____ the survey last Friday.
Choose an answer.
The solution, step by step
A — completed
The method in action
- “Last Friday” refers to a completed period, so the simple past fits. “Has completed” does not work here with this definite past date; the other forms do not convey the intended meaning.
Mina _____ this laboratory since 2022 and still works there.
Choose an answer.
The solution, step by step
B — has managed
The method in action
- “Since 2022” provides the starting point, and “still works there” confirms continuity. The present perfect simple fits; the simple past does not convey that continuity in this sentence.
By the time the courier arrived, we _____ all the parcels.
Choose an answer.
The solution, step by step
C — had sealed
The method in action
- The parcels had already been sealed before the courier arrived: the past perfect marks this earlier action.
According to the notice, the shop _____ at ten tomorrow.
Choose an answer.
The solution, step by step
D — will open
The method in action
- “Tomorrow” places the opening in the future. A present tense used for a schedule might appear in another set of options, but it is not offered here.
Our receptionist usually _____ the visitor list before nine.
Choose an answer.
The solution, step by step
A — checks
The method in action
- “Usually” indicates a habit. The singular subject requires “checks”; “checking” would be an isolated non-finite form.
We will send the invoice as soon as the order _____.
Choose an answer.
The solution, step by step
B — ships
The method in action
- In this time clause introduced by “as soon as,” the simple present expresses a future event; “will ship” does not fit here. “Ships” can mean “is shipped”: in shipping terminology, “ship” can also be intransitive.
The pitfall
Matching one word to a tense without reading the rest
“For three years” alone does not prove an activity is ongoing. “I worked there for three years” describes a completed job; “I have worked here for three years” connects the duration to the present. Do not reduce a time relationship to a trigger word.
Also check the voice. A sentence may require the passive rather than a different tense: in “the order was shipped,” the subject is what was shipped; in “the supplier shipped the order,” the subject is who shipped it. Both sentences can describe the same event, but the subject’s role and verb construction change.
How can you derive a rule from your mistake?
Write down the time clue and the relationship it establishes. Then change the clue: “yesterday” becomes “since Monday,” or “tomorrow” becomes “last week.” If the new sentence requires another form, explain why.
Then try an unfamiliar sentence of the same type. Reciting the tense name is not the goal; you should be able to justify the timeline using the information actually present.
Key takeaways
- Place the action on a timeline before naming the tense.
- A cue word does not replace context.
- Also check the subject, agreement, and voice.
