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
