Task 33.Ask a special question to every part of the sentence in bold. Work in pairs (St 1 & St 2).

1. One of the most pressing issues facing nanoscientists and technologists today is that of communicating with the non-scientific community.

2. Governments and corporations worldwide have ploughed over $4 billion into nanotechnology in the last year alone.

3. Nanotechnology is already all around us if you know where to look.

4. Many of the companies working with nanotechnology are simply applying our knowledge of the nanoscale to existing industries.

5. Degusssa have been producing carbon black, the substance that makes car tyres black and improves the wear resistance of the rubber, since the 1920s.

6. At least scientists are making progress in identifying the gaps – the 'known unknowns' as they call it.

7. They find that serious knowledge gaps pervade nearly all areas of basic nanotechnology EHS knowledge.

8. "We expect that further empirical research will presumably reduce most areas of uncertainty, although it is likely to be time-consuming and expensive" Khara Deanne Grieger, a PhD student in DTU's Department of Environmental Engineering, tells Nanowerk.

9. This analysis was motivated by the aim of assisting the development of nano-EHS research priorities.

10. Grieger, Hansen and Baun recommend that further attention be given to the assessment and development of standardized testing procedures, equipment, materials as well as the full characterization of nanomaterials in order to most effectively reduce uncertainties in the near term.


Task 34.Summarize the information you have got from the student of another group. Work in pairs. Your opponent from the different group should say whether you are correct or not in understanding the information.


Task 35. Role-play: press conference.

Team 2 (3 students) do not support the idea of fast development and implementation of nanotechnologies without studying EHS risks of nanomaterials.

All the rest students are journalists. Their task is to understand possible benefit and danger from nanotechnologies implementation.
