Royalty-free images for commercial use

If, like me, you are developing your own teaching materials and lack time to create your own illustrations or to take a million of suitable pictures, than chances are you are in a constant search for royalty-free images for educational and commecial use.

Over the years I have narrowed down a list of online websites with royalty-free images, which you can see in the embedded slideshow below. Apart from the links, the slideshow includes the terms of use that each of the websites offers.

This is the presentation I created for my A2 class, it covers the structure of the Passive Voice in the Present and Past Simple tense, it also includes a clear explanation of the difference between transitive and intransitive verbs, as well as the difference between BY and WITH. There are also exercises to practice each of the covered aspects.

The presentation starts with a clear explanation of the difference between the Passive and Active Voice and the transformations that take place when an active sentence is turned into a passive one.

 

Then comes a detailed explanation on how to form statements, negations and questions in the Passive voice.

This is followed by a clear explanation of the difference between transitive and intransitive verbs.

Finally, the slideshow covers the difference between BY and WITH and explains the cases of use of each of them.

There are also exercises to practise each of the aspects covered in the slideshow.

The exercises include sentence transformation and fill-in  the gap drills.

The slideshow is available on authourstream and slideshare.
