This article examines children's comprehension of the "get"-passive relative to the "be"-passive in an attempt to systematically compare the acquisition of both types of passives. It discusses the findings of two experiments (a picture-matching task and an act-out task) with children ages 36. Results from the picture-matching task indicate that 3-year-olds are above chance only with "get"-passives with "animate" subjects, which suggests that early "get"-"passives" may actually be (active) control structures requiring a thematic agent. Children 4-6 years old perform equally well with "get" and "be." Results from the act-out task further reveal that children ages 4;02 and older interpret the "by"-phrase in nontruncated actional passives (with "get" and with "be") and analyze it as agentive. This is consistent with a raising analysis for both passive types after the age of 4. There is no advantage to either type of passive at this point, contra previous claims in the literature.
