Presentation

On the tape you heard various instructions about how to set up the QD Personal Computer. These instructions were either in the positive or negative. Look at the examples below.

POSITIVE NEGATIVE

Look at the back of the computer Don't use the VHF one (aerial socket)

Find the aerial lead Don't worry about which end you use

Connect one end of the aerial lead Don't forget to turn the volume down

Take the micro-disk drive Don't use force

Do the same with the other end Don't try to repair it yourself

Tune in your TV

Turn it on

Press a button

Use the tuning mechanism

Insert the 'Welcome' disk

These forms of the verb are called imperatives.

The positive imperative is the verb stem, e.g. look, find, etc.

The negative imperative is don't + the verb stem, e.g. don't use, don't try, etc.

In English the imperatives have only one form. It is the same form if you give instructions

to one person or to many people.

Now use the diagram below to give instructions. You must complete the sentences, using the verbs given. If you see an X in the diagram, you must use a negative imperative.

Choose from the following verbs:

take, push, follow, connect, look, do, insert, find, plug, switch
