I did a exercise with indirect speech, can anybody check it?

1. "Have you visited the NA?" she asked me.
-> She asked me if I had visited the NA.

2. "What do you think of the hotel food?" I asked her.
-> I asked her what she thought about the hotel food.

3. "Will you travelling by train?" she asked me.
-> She asked me If I travell by train.

4. "Do you know the way to the Opera?" I asked her.
-> I asked her if she knew the way to Opera House.

5. "How much did you pay to stay in the hotel?" she asked me.
-> She asked me how much I paid for the hotel.

6. "Are you thninking of changing hotels?" I asked her.
-> I asked her if she thought of changing hotels.

7. "Do you have to leave at 10.00?" she asked me.
-> Ahe asked me if I had to left at 10.00.

8. "Would you come with me to the station"? I asked her.
-> I asked her to come with me to the station.

Rethink #s 3, 4, 7.

Your exercise with indirect speech looks mostly correct. Here are a few suggestions for improvement:

1. "Have you visited the NA?" she asked me.
-> She asked me if I had visited the NA.
(Note: "the NA" should be replaced with the full form of NA)

3. "Will you be traveling by train?" she asked me.
-> She asked me if I would be traveling by train.
(Note: The correct verb form should be "will be traveling" instead of "travell")

7. "Do you have to leave at 10.00?" she asked me.
-> She asked me if I had to leave at 10.00.
(Note: "left" should be changed to "leave")

8. "Would you come with me to the station?" I asked her.
-> I asked her if she would come with me to the station.
(Note: The word "to" should be included before "the station")

Overall, your understanding of indirect speech is good. Keep practicing, and you'll become more confident in using it correctly. If you have any more questions or need further clarifications, feel free to ask!
