Question

1. I'm excited because I get on the airplane for the first time.

2. This is my first trip abroad, so I am very excited.

3. I got off the airplane at the airport.

4. I waved on the laddle to the airplane.

5. I was excited because I could go abroad for the first time in my life by plane.

6. I arrived at Kimhae Airport and got on the plane. I was satisfied because I had wanted to go abroad to study English.

(Would you checked The English expressions?)

Answer 1

I don't know what you meant to say in # 4, because "laddle" is not an English word.

The rest are correct -- but # 3 is unncecessary. The only place to get off an airplane is at an airport.

Also, "happy," or "thrilled" would be better than just "satisfied" in # 6.
