My home is a windmill
by Josh Summers, aged 14
My home’s different from where my friends live because I live in a19th century windmill! My parents saw it one day, and bought it. It was in poor condition, but it was repaired and now it’s fantastic! The windmill was once used to make flour from corn. The corn store used to be downstairs, where our kitchen is now, and horses came there to deliver the corn. The enormous 20‐metre sails are still on the front, but they don’t turn in the wind like they used to because it’s too dangerous, so birds live in them instead. There’s always a ladder up the side of the windmill so that dad can paint it and keep it a nice cream colour. He also cleans the windows, although a company comes to do the top ones as the ladder’s too short. Inside it’s like a tent with six sides, and it becomes more pointed towards the top, so the rooms get smaller. My room’s under the roof and I get a fantastic view – it’s like looking out of an airplane window. There are some other houses around now, and a new main road, but I can relax and make a noise when I play my guitar up there and no one can hear me! I can hear everything, though, like the birds when it’s quiet, which is really calming, or the very loud storms, which I can see coming towards us. And I actually find it easier to concentrate on my school work up there, as my brothers and sisters don’t want to climb up all the stairs, so they don’t disturb me! I can’t imagine living anywhere else!
1. What is Josh trying to do in the text?
A compare his home with his friends’ homes
B explain why his family chose to live in their current home
C tell readers about advantages of living where he does
D suggest how his home could be improved
2. What does Josh say about the outside of the windmill?
A Wild creatures have made their homes there.
B It’s covered in dark paint.
C There’s a ladder that goes right to the top.
D The windows frequently need cleaning.
3. Josh says that his room
A is a bit like an airplane inside.
B is a good place for practicing a musical instrument.
C is the largest one in the windmill.
D is better for relaxing in than doing school work.
4. What does Josh say about the different sounds he hears in the windmill?
A He dislikes the noise of the sails in the wind.
B He enjoys listening to all the birds.
C He feels nervous when a loud storm comes along.
D He’s pleased that he’s not disturbed by any noise.
5. What would a visitor from the 19th century say if they saw the windmill now?
A It’s great that they’ve kept the corn store as it was. The horses used to love coming there.
B The sails are a lot smaller than they used to be. I suppose that’s for safety reasons.
C It’s still in the same condition as before. The owners never looked after it then, either.
D You can still see the windmill from miles away. Of course, there weren’t all these buildings around it then, as a busy road going past.
