1. The taxi fare was too high.

2. The taxi fare was too expensive.
(Which one is right in this case?)

3. After I went through the entry procedure, I could go anywhere in the city.
(Is this sentence right? Do you have other expressions?)

4. Later I had to hand that one to an acquaintance for free.

Thank you for your help. Would you check them, please?

1 is fine. 2 would be better without "too."

3 is fine, yes.

For 4, I don't know what "that one" is -- once I know that, I can see if the sentence makes sense or not.

1. Both sentences are grammatically correct and convey the same meaning. "The taxi fare was too high" implies that the cost of the taxi ride was more than expected or deemed reasonable. Similarly, "The taxi fare was too expensive" conveys that the fare charged for the taxi ride was excessively costly. Both sentences express dissatisfaction with the cost of the fare.

2. The sentence "After I went through the entry procedure, I could go anywhere in the city" is grammatically correct. However, if you're looking for alternative expressions, you could say:

- "Once I completed the entry procedure, I had unrestricted access to the entire city."
- "Once I finished the entry procedure, I was free to explore any part of the city."
- "After going through the entry procedure, I had the freedom to move around the entire city."

3. The sentence "Later I had to hand that one to an acquaintance for free" is grammatically correct. However, without further context, it is difficult to determine the specific meaning. The phrase "that one" leaves room for interpretation, as it is unclear what is being referred to in this sentence. If you can provide more context, I can help you further evaluate the sentence.
