(#1,4, 7, are active voice sentences. The others are passive voice sentences. Which passive sentences are not grammatical? Would you check them, please?)

1. He made me go there.

2. I was made to go there by him.
3. I was forced to go there by him.
These are fine.

4. He had me go there.
5. I was had to to there by him.
6. I was asked to go there by him.
4 and 6 are fine. 5 is incorrect.

7. He let me go there.
8. I was let to go there by him.
9. I was allowed to go there by him.
7 and 9 are fine. 8 is incorrect.

Certainly! Let's check the grammaticality of the passive voice sentences you provided:

1. He made me go there. [Active voice - grammatical]
2. I was made to go there by him. [Passive voice - grammatical]
3. I was forced to go there by him. [Passive voice - grammatical]

4. He had me go there. [Active voice - grammatical]
5. I was had to go there by him. [Passive voice - not grammatical]
Explanation: Sentence #5 is not grammatically correct. In passive voice constructions with verbs like "have," the verb "have" is followed by the past participle form of the main verb. In this case, "had" should be followed by "gone" (past participle of "go"), but "had to go" is not a valid formation in passive voice.

6. I was asked to go there by him. [Passive voice - grammatical]

7. He let me go there. [Active voice - grammatical]
8. I was let to go there by him. [Passive voice - not grammatical]
Explanation: Sentence #8 is not grammatically correct. In passive voice constructions with verbs like "let," "allow," etc., we use the structure "be + past participle + infinitive." In this case, it should be "I was let go there by him."

9. I was allowed to go there by him. [Passive voice - grammatical]

In summary, sentences #5 and #8 are not grammatically correct in passive voice construction.
