  • Hello, and welcome to today's Grammar Gameshow!

  • I'm your host, Will,

  • but I'm no has been!

  • And of course, let's not forget Leslie,

  • our all-knowing voice in the sky.

  • Hello, everyone!

  • Tonight we're going to ask you three questions about

  • Have to and must.

  • Those two little expressions that are to do with

  • obligation and make all the rules!

  • OK! Now, let's meet our contestants!

  • Hi, everyone. I'm Simone!

  • And contestant number two?

  • Hello, everyone. I'm Mya!

  • Welcome back, Mya!

  • OK! Let's get going.

  • And don't forget you can play along at home too

  • Our first question is multiple choice.

  • Which of these uses of 'have to' and 'must'

  • is different from the others?

  • a) You must wear your seatbelt.

  • b) You have to wear your seatbelt.

  • c) You mustn't wear your seatbelt.

  • d) You don't have to wear your seatbelt.

  • D is different because it describes a voluntary action

  • Leslie?

  • You're not wrong there, Simone.

  • 'Must', 'mustn't' and 'have to' all talk

  • about obligations - for example, rules that

  • you need to follow.

  • But 'don't have to' is the opposite

  • the actions it describes are voluntary.

  • Such as, Will doesn't have to give anyone any points!

  • He's the boss!

  • True! But, since I'm nice!

  • Simone, you can have two points.

  • And Mya, I liked your 'thinking face' there,

  • two points to you!

  • Hang on! That's not fair. Why does

  • Fingers on the buzzers.

  • Here comes question two! True or false:

  • There is no difference between

  • 'have to' and 'must' for obligations.

  • False!

  • Leslie?

  • It is false!

  • Although many use them interchangeably,

  • in fact,

  • we use 'have to' for external obligations,

  • and 'must' for internal obligations.

  • OK. One point for that.

  • Now for the quick fire part.

  • Based on what Leslie has just told us,

  • tell me if these obligations would take

  • 'have to' or 'must'.

  • You decide not to smoke.

  • I mustn't smoke.

  • Correct!

  • The government wants you to pay your taxes.

  • We have to pay taxes.

  • Correct!

  • You don't want to exercise, but the doctor tells you to.

  • I have to exercise.

  • Correct!

  • You want to brush your teeth more.

  • I must brush my teeth more.

  • Correct!

  • You try to resist eating chocolate.

  • I mustn't eat chocolate.

  • Correct!

  • Your parents tell you to do homework.

  • I have to do homework.

  • Correct!

  • Well done both of you.

  • Have 13 points between you.

  • It's time for our final question:

  • 'Must' and 'have to' are modal verbs.

  • But why is 'have to' different from other modal verbs?

  • Trick question!

  • All modal verbs are followed by a bare infinitive verb

  • so there is no difference.

  • Leslie?

  • It's true that all modals, including 'must' and 'have to',

  • are followed by a bare infinitive

  • But that's not our answer.

  • Ouch, Simone. You crashed and burned there.

  • Mya, I can offer it to you.

  • Is it because modal verbs don't change their form,

  • but 'have to' does?

  • Leslie?

  • Absolutely right!

  • Unlike other modal verbs,

  • 'have to' changes to show person

  • for example, 'have to', 'has to' -

  • and time

  • for example, 'had to', 'didn't have to'.

  • Its meaning doesn't change though.

  • Good job Mya.

  • You know, I'm taking 20 points away from Simone

  • for stupidity,

  • and giving them to you.

  • No!

  • Well that brings us to the end of today's

  • Grammar Gameshow.

  • Let's count out the points.

  • And the winner is

  • Mya...

  • with 37 and a half.

  • Well done!

  • Here's what you've won!

  • It's a cuddly toy!

  • You've finally got a friend!

  • We'll see you again next week,

  • where you can play for an even bigger prize.

  • And, Simone,

  • what happened? You were doing so well!

  • Well, to be honest I…

  • Unleash the sheep.

  • It looks like we'll need another contestant.

  • Thanks for joining us.

  • Say goodbye, Leslie.

  • Goodbye, Leslie.

  • See you next time!
