1 and 2 are fine.

3 and 4 have impossible verbs, thus making no sense.

5 and 8 are the best of the next set of sentences. The others are a bit strange, but the meaning comes through.

1. The gate is shut at 7. - This sentence suggests that the gate is closed specifically at 7 o'clock. It indicates a specific time at which the gate is closed.

2. The gate gets shut at 7. - This sentence is similar in meaning to the first one. It also suggests that the gate is closed at 7 o'clock. Here, "gets" is used as a verb of action, indicating that the gate is actively being closed at that time.

3. The gate grows shut at 7. - This sentence implies a gradual process of closure. It suggests that the gate slowly and progressively closes until it is shut at 7 o'clock.

4. The gate becomes shut at 7. - This sentence indicates a change or transformation in the status of the gate. It suggests that the gate was previously open and then at 7 o'clock, it transforms or changes into a state of being shut.

In terms of meaning, sentences 1, 2, and 4 convey a similar idea but with different phrasing. Sentence 3 presents a slightly different sense of closure, emphasizing a gradual process.

Moving on to the second set of sentences:
5. The gate is shut now. - This sentence simply states that the gate is currently closed. It does not provide any specific information about when it was closed.

6. The gate stands shut now. - This sentence conveys the idea that the gate is firmly closed or fixed in a shut position at the moment.

7. The gate lies shut now. - This sentence suggests that the gate is in a state of being closed, placed horizontally or resting in a closed position.

8. The gate remains shut now. - This sentence implies that the gate was closed before the present moment and continues to be closed at the present time. It carries a sense of continuity in the closed state.

9. The gate rests shut now. - This sentence is similar to sentence 7, indicating that the gate is in a state of being closed, possibly in a relaxed or resting position.

All of the sentences 5-9 are grammatically correct. Although there are subtle differences in phrasing and implications, they generally convey the same meaning: the gate is currently closed.
