B2.2 and all students: Interesting video about sustainable growth

This video clip is connected with conversations and listenings we have done in class and is fairly easy to understand.CLICK HERE:If you click onto youtube at the bottom right and then onto something that looks like an envelope, you will have subtitles in English. At the beginning, what's written is quite wrong - for example, they say "how much bull* can the world suffer" and the subtitles say "how many all can I supper!" - but after that they get better!  * bull is short for "bullshit" which is a slang way of saying "lies". It is interesting.
For those of you who had trouble with the first section of the Grammar Test, I'm including a work sheet  on the use of the Present Perfect, Present Perfect Continuous and the Past tenses.
