Passive and Active Sentences


Here's some example of passive and active sentences :

1.            a. (+) Somebody stole my bag in the shop
b. (- ) My bag was stolen in the shop
reasons :         
ü  the A sentence is an active sentence because the subject (somebody) is in front of the sentence
ü  the sentence is a past simple tense because the verb (stole) is verb 2
ü  the pattern of active sentence in past simple : Subj + V2 + Obj
ü  when the sentence change into passive, we must put the object (my bag) in front of the sentence
ü  the pattern of passive sentence in past simple : Subj + was/were + V3
ü  we choose “was” as the suitable answer because the subject (my bag) is a singular
ü  then, change the verb 2 become verb 3 (stole → stolen), it’s an irregular verb

2.            a. (-) That pie was made by Susan
b. (+) Susan made that pie
reasons :
ü  the A sentence is a passive sentence because the object (that pie) is in front of the sentence
ü  and the subject (Susan) is in the end of the sentence
ü  there’s also “by” before the object, that shows the sentence is a passive
ü  the sentence is a past simple tense because there’s “was”
ü  “was made” is a verb phrase
ü  the pattern of passive sentence in past simple : Subj + was/were + V3
ü  when the sentence change into active, we must put the object (Susan) in front of the sentence, so it becomes a subject
ü  the pattern of active sentence in past simple : Subj + V2 + Obj
ü  “made” is still “made” in verb 3, it’s an irregular verb

3.            a. (+) An artist wrote that interesting article about Paris
b. (-) That interesting article about Paris was written by an Artist
reasons :
ü  the A sentence is an active sentence because the subject (an artist) is in front of the sentence
ü  the sentence is a past simple tense because the verb (wrote) is verb 2
ü  the pattern of active sentence in past simple : Subj + V2 + Obj
ü  “was written” is verb phrase
ü  when the sentence change into passive, we must put the object (that interesting article) in front of the sentence
ü  the pattern of passive sentence in past simple : Subj + was/were + V3
ü  we choose “was” as the suitable answer because the subject (that interesting article) is a singular
ü  then, change the verb 2 become verb 3 (wrote → written), it’s an irregular verb

4.            a. (+) They canceled all flights because of fog
b. (-) All flights were canceled of fog by them
reasons :
ü  the A sentence is an active sentence because the subject (they) is in front of the sentence
ü  the sentence is a past simple tense because the verb (canceled) is verb 2
ü  the pattern of active sentence in past simple : Subj + V2 + Obj
ü  when the sentence change into passive, we must put the object (all flights) in front of the sentence
ü  the pattern of passive sentence in past simple : Subj + was/were + V3
ü  we choose “were” as the suitable answer because the subject (all flights) is a plural
“canceled” is still “canceled” in verb 3, it’s a regular verb
