Congratulation!

You are just bought the best bike

In the world. Your speedy wobbler 

will give you years and years of happy cycling.

Life is easy with a new speedy wobbler.

Do you remember old bicycles? you had to replace bits

when they fell off. With  Andres you don´t have to do

that! It´s all in one piece. If you look after it, nothing will go 

wrong. You can Andres without worrying.

There are just two things you have to remember. before 

every ride you must pump up the tires and you must oil the

chain. Have a happy wobble!

 

Must is to tell somebody what to do.

    You must pump up the tires.

    = The bike maker says you can´t leave the tires flat.

    You must oil the chain.

    = The bike maker says you can´t forget to oil the chain.

Must is also to remind yourself to do things.

    I must feed my dog. He is hungry. 

    = I need to remember to feed my dog.

    I must pump up my tires. they are flat.

    = I need to remember to pump up my tires 

Should is to tell somebody that you think something is a good idea, or to say that you think something is the right thing to do.

    That bike looks dirty. You should wash it.

    = I think it´s a good idea to wash it.

    

    You should be careful when you ride your bike.

    = I think it´s the right thing to do

Have to is to say that you cannot choose what to do. There is only one thing you can do. Something bad will happen if you do not do it. 

    I have to go to school. (I cannot choose to stay at home. If I stay at home, my parents and teacher will be angry.)

Do not have to is to say that you cam choose what to do. Look: 

    It is the weekend tomorrow. I do not have to get up early 

    (I can choose what to do. I can get up early or I can get up late.)

The past of have to is had to, the past of do not have to is did not have to.

I have to wear a uniform at school. (present) 

I had to wear a uniform at school (past)

I do not have to get up early today. (present)

I did not have to get up early yesterday (past)
