A second set of 20 transformation sentences practicing the active causative form. Supply the missing base verb to complete each causative sentence. This exercise uses a wider range of contexts than exercise 1, including some where the tense of had varies.
Grammar reviewThe active causative — extended practice
The active causative (have + person + base verb) describes situations where someone arranges for a named person to carry out an action. This exercise extends that pattern across a wider range of contexts.
The transformation pattern: Original: “Mary cleaned the refrigerator.” Causative: “Charlotte had Mary clean the refrigerator.”
Tense flexibility: The tense of the whole sentence is carried by had, not by the following verb. The verb after the named person always stays in the base form regardless of tense: “I will have her call you.”“He had them redo it.”“She has him drive her to work.”
Distinguishing active from passive causative:
If you can answer the question “Had whom?” → active causative (a person follows had).
If you answer “Had what done?” → passive causative (a thing follows had, verb is past participle).
