Build the requested structure before judging the ending.
Review past negatives, present continuous, two perfect forms, future perfect and present passive through six specified constructions.
The count records matching answers on six selected grammar items. It is not a writing grade, percentile or CEFR level. Every explanation and this full guide are available whether your count is zero, partial or perfect.
Six forms, with the meaning fixed
These items name the requested construction rather than treating one time expression as an automatic tense selector. Did not takes a base verb. Present continuous needs a present form of be and an -ing form. Perfect simple constructions use a form of have and a past participle, while the passive includes be and a past participle. Each auxiliary contributes something different.
Change a completed action’s viewpoint
Consider a new fictional example: The conservator had repaired the hinge before the cabinet was moved. Had repaired places the repair before a later past event. Now describe a plan from today: By Friday, the conservator will have repaired the hinge. The deadline and viewpoint have changed. These are illustrative sentences, not new scored questions or promises that the work will happen.
Check auxiliary, agreement and participle separately
When reviewing a mistake, mark the first auxiliary, identify its subject and inspect the main verb form. In has created, has agrees with a singular subject and created is the participle. In will have printed, have stays in its base form after will. A passive form also changes who or what receives the action; a similar-looking ending does not preserve the same meaning.
Write the rule beside a new sentence
Choose one construction you missed and write a fresh short sentence. State the intended time relationship and whether the subject acts or receives an action. Then change only one feature, such as singular to plural or active to passive, and explain the necessary edits. Compare with the linked grammar reference after writing. This is a revision activity, without a measured improvement rate.
A specified form is narrower than fluent use
The six tasks do not cover every tense, aspect, irregular participle or conversational choice. Recognising a requested form does not show that you can choose it spontaneously in a long text. Other constructions may express different meanings in other contexts. Repeating these fixed items after reading the keys may reflect memory. Use new sentences to continue practising rather than assigning yourself a permanent grammar level.
