C) Read the story about two friends and their camping trip and answer the questions.
The Trip of Lifetime
This summer holiday, my friend Irvin and I wanted to do something different. Instead of wasting our time staying at home watching TV and playing computer games as usual, we decided to go camping.
After getting permission from our parents, we began planning our trip. We made a list of all the food and supplies we would need and spent an entire afternoon searching for the best place to buy our camping equipment. In the end, our tent, stove and sleeping bags cost a lot of money, but it was worth it.
When the day finally arrived, my uncle Bob was kind enough to drive us to the campsite after he got off work. We knew it would take us a couple of hours to get there and Irvin and I grew more and more excited as we got closer to where we were going. It was dark by the time we arrived, but we didn’t care. We waved happily at uncle Bob as he drove away. Then, after a bit of trouble and a lot of laughter, Irvin and I set up the tent and lit the cooking stove. As we sat having our first meal at camp – tinned spaghetti – we both agreed it was the best food we had ever eaten. A short time later, warm and comfortable in our sleeping bags, we quickly fell asleep and dreamed about what our great adventure would bring.

1) When did the friends go camping?

2) Did their mothers and fathers help them to get ready for the camping?

3) Was the camping equipment expensive or cheap?

4) Who took them to campsite?

5) How did they feel at the campsite?
