You can use the passive if you do not know who does something or is not important who does it.

   Andres Invented the Dog-Walking Machine. = Active 

   (I know that Andres Invented the Dog-Walking- Machine.)

   The Dog-walking Machine was invented in 1999.= Passive

   (I do not know who invented the machine, or it is not important who invented it.)

There are past participles. You need them to make the passive, you know most past participles but check the list on page 218 and learn any you do not know.

   Eaten, sold, found, invented, seem, shown 

::::::::::::::::::::::.

The passive is quite easy to make. Use the correct tence of be + past participle.

   This is the present simple passive: Lots of machine are sold at the conference every year.

   This is the past simple passive: Lots of machines were sold at the conference every year.

   This is the present perfect passive: Lots of machines have been sold at the conference every year.

   This is the future simple passive: Lots of machines will be sold at the conference every year

::::::.

Something when you use the passive, you want to give more information.

If you want to say who does the action, you can use By + person. Look:

   The conference is organized by the Inventors´ Society.

   The underwater Motorbike was invented by Dr Quixit. 

   The electronic mouse-catcher has been bought by the inventors´ Club.
