3. Read the story and mark the sentences T (true) or F (false)
This summer holiday, my friend Irvin and I wanted to do something different. Instead of wasting our time 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 day searching for the best place to buy our camping equipment. In the end, our tent, stove and sleeping bags cost a lot 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 a tent and lit the cooking stove. As we sat having our first meal at the camp – tinned spaghetti – we both agreed it was the beat 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.
