Перевелите и помогите с заданием ПОЖАЛУЙСТА.
When, I was at primary school, I liked to take trips with my parents. Those were great days for all of us. We could talk for hours about everything, laughed and had a lot offun. One day when I was about 7, we took a trip to one of the biggest mountains in our region. I could not sleep the night before because I was so excited about the trip. The weather was hot and sunny. The first hour of climbing was not hard. Then it became more difficult and I felt tired. 1 wanted to take a rest for at least a minute, but I could not stop because my father said: “You need to put up with some difficulties. If you can do with this now, you’ll be a better climber than me.” So, we were climbing and my father was encouraging me. While I was climbing up along a tough and narrow path, I felt absolutely exhausted. But soon we took a short break before climbing to the top of the mountain.At that time the fresh and sweet wind made me feel so cool. I said: “Father! Hurry up! I want to see the top!” Two hours later, I was able to get to the top of the mountain. I felt so proud of myself. On the top I could see the huge sun going down in the west. It looked like a big fireball. I can’t remember what my father told me on the top but now I realize that he taught me the way to get over my problems and helped me develop self- confidence.
Are these statements true (T) or false (F):
1. The boy wanted to climb the mountain very much.
2. The boy slept well before the trip.
3. The weather was bad during the trip.
4. The boy felt tired at once.
5. The boy wanted to become a better climber.
6. The boy could take a rest quite often during their trip.
7. They took the trip at sunset.
8. The boy learned a good lesson during the trip.
