Read the following information

Dan, Ben and Tom are getting ready for a camping trip.

Dan: I’ll go and buy some food. Shall I get the train tickets too?
Ben: Yes, good idea. I’ll give you the money when you get back. I’ll check the tent is OK. Will you help me, Tom?

Camping Trip Checklist

• Food: Dan

• Train tickets: Dan

• Check tent: Ben and Tom

Section A: Will and Shall

You use 'will' when you offer or promise to do something. Do not confuse this with its use for the future tense.

"Will" can be used also as a spontaneous decision, in the moment, rather than a planned future event:

• Offer:

  • “I’ll go and buy some food.”

  • "I'll help you carry those heavy bags."

• Promise:

  • “I’ll pay you when you get back.

  • "I won't tell anyone your secret."

• Spontaneous Decision:

  • "The phone is ringing. I'll get it!"

  • “I’ll go and get the tent right now!”

You can also use Shall I …? / Shall we …? to offer to do something.

• Shall I get the train tickets.

• Shall we double check we have everything for the camping trip?

To ask if someone is going to do something you can use Will you …?

• Will you help me?

• Will you hand me the tent pegs?

You can use won’t about people or animals to show they don’t want to do something.

• They won’t let us stay at the campsite near the lake.

• I’ve given the cats their food but they won’t eat it.

You can also use won’t to talk about machines that don’t work.

• My computer will won’t turn on. I think I need a new one.

• The tent zipper is stuck, it won’t open!
