Next weekend, two teenagers are going to walk non-stop for 24 hours to try to raise money for a charity for the homeless in their town. The charity offers a bed for the night and a hot meal for young homeless people. The teenagers, Dan Thomas and Ollie Green, want to do something to help these people.

The two boys often go for long walks. Walking is their hobby, but they have never completed 36 miles all at once and they don't usually walk at night. They did a practice walk last month, but got a bit lost, so they have planned the walk very carefully in the last two weeks. They will have to carry everything they need, including food and extra clothes. And, because they are walking at night, they will have to wear special jackets that people can see in the dark. They hope that the weather will be good because the walk is in summer but, as Ollie says, You never know in England. They will prepare for wet weather and very hot weather, too.

The boys' parents and teachers say that they are very happy that the boys are being so responsible. The walk will take them up hills and down into valleys, past a river and across fields, but the boys aren't worried. 'There are no wild animals around here,' they say.

You can give money to the boys by visiting the 'just giving' page on their website. And, if you want to cheer them on when they reach the finishing line, come to the town centre on Sunday evening.

Choose the correct alternatives
1 The homeless charity will get money/a bed as a result of Dan and Ollie's walk.
2 The two boys couldn't see in the dark/find their way when they did their practice walk.
3 The boys will eat at cafés/outdoors during the walk.
4 They can/can't be certain that the weather on the walk will be good.
5 The boys feel worried/relaxed about walking through the countryside.
