Read the article about Jason’s house. Are these statements True (T), False (F) or is the information Not Mentioned (NM)?

Jason lives in a big house near the sea. That’s not really unusual, is it? But Jason’s house is very big. There are 20 bedrooms, two kitchens, a big dining room for 40 people and a swimming pool, too! You’re probably thinking Jason has got a very big family, but you’re wrong! Jason lives in a hotel.

Jason’s parents own The Jackson Star Hotel in the lovely little seaside town of Barnaby. Lots of people go there in summer for their holidays and stay at Jason’s hotel. It’s very popular! Jason lives with his mum and dad in a small flat at the top of the hotel. They work in the hotel and Jason helps when he is not at school. He sometimes takes the rubbish out and makes the beds.

So, does Jason like living in a big hotel? Jason says, ‘Yes, I like my room. It’s very high up, and from one window I can see all over the town and from the other window I can see the sea. I’ve got a big desk in my room with a computer on it so I can do my homework. And I’ve got my own TV. My friends like staying here because the bedrooms are comfortable, and we get very good food! I like the people, too. They come from different places around the world.’

Is there anything he doesn’t like? Jason answers, ‘In the winter, there aren’t a lot of people here and I sometimes get frightened at night. The hotel is big and empty and it’s like a scary film!’

1. All houses near the sea are the usual ones.

2. Jason has got a big family.

3. There are three windows in his room.

4. He can see his friends’ houses from his room.

5. He never likes the hotel food.

6. Jason doesn't like watching scary films.
