REVISION: VERB TENSES

SOME TIPS TO DO THIS ACTIVITY: 

Read the whole sentence first before choosing the tense.
Don’t look only at the verb — the context gives the answer.

Underline the time expression before writing the verb.
Words like already, yet, while, by the time, tomorrow at this time, last week are the key.

Watch the difference between simple and continuous forms.
Ask yourself: Is the action finished, repeated, or in progress?

Use continuous tenses for actions in progress at a specific moment.
(At 8 p.m., while I was studying. This time tomorrow they will be doing …)

Use simple tenses for routines, facts, and completed actions.
Don’t use continuous forms if the action is habitual or finished.

Present Perfect is not Past Simple.
Have/has + past participle is different from past simple.
Check if the time is finished (yesterday, last year) or unfinished (today, this week, already, yet).

Past Simple and Past Continuous often work together.
One action was in progress, and another interrupted it.

Past Perfect = the earlier past.
If two actions happened in the past, use Past Perfect for the one that happened first: When the children arrived, he had already prepared lunch. 

Check the order of past events carefully.
Ask yourself: What happened first? What happened later?

Remember: after “if”, we do not normally use “will” or "would"
(If I see her, I will tell her. NOT *If I will see her… If I were you, I wouldn't study only the last day.) 

Modal verbs need the base form.
After can, could, will, would, must, use the infinitive without to.

Don’t forget negative forms.
Check carefully if the sentence needs don’t / doesn’t / didn’t / won’t / haven’t…

Questions need the correct word order.
Be careful with: auxiliary + subject + verb
(Did you go? / Has she finished?)

Some verbs are irregular in the past and past participle.
Study them carefully: go–went–gone, see–saw–seen, take–took–taken…

Be careful with past participles.
Present Perfect and Past Perfect need the 3rd form of the verb, not Past Simple.

“Since” and “for” are not the same. They usually go with present perfect, like "already", "just", "yet".
Since = starting point
For = period of time

• One word can change the tense completely. Don’t ignore markers like still, just, ever, never, when, while, by.
• “Ago” = Past Simple. Never use Present Perfect with ago.  
• “By” often signals a perfect tense. Especially with by the time, by tomorrow, by next week.  
• “While” usually introduces a continuous action.“When” often introduces a shorter action that interrupts another one.  
• Present Simple can talk about the future (timetables, schedules). The train leaves at 8.30. 
• Present Continuous can also express future arrangements. I’m meeting Laura tomorrow. 

State verbs are not usually used in continuous forms. Be careful with verbs like know, like, love, want, understand, believe.

Future forms depend on meaning. Don’t choose randomly:

• will → spontaneous decision / prediction
• going to → plan / intention / evidence
• Present Continuous → fixed arrangement
• Future Continuous → action in progress in the future  

Check subject–verb agreement carefully.
Singular subject = singular verb (He works, She has)

Leave 2 minutes at the end to check everything.
Most mistakes are small: missing auxiliaries, spelling, endings, and irregular forms.
