Unit 5.3

Lead-in

1. Describe the pictures. What do you think each person’s lifestyle might be like?

   Talk about:

   • family: not married/single, extended family, only child, etc.
   • house: modern/traditional, flat, cottage, penthouse, etc.
   • location: in the city centre, a fashionable district, the countryside, etc.
   • dress: smart, fashion victim, casually dressed, unconventional, classy, well-dressed, fashion-conscious, etc.
   • interests/entertainment: playing sports/computer games, painting, going to concerts/art exhibitions, clubbing, reading, watching TV, travelling, etc.
   • education: primary/secondary/high school, university, degree, etc.
   • work: well-paid/poorly-paid, career, qualified, etc.
   • character: easy-going, generous, quiet, reserved, fussy, independent, patient, hard-working, etc.

   e.g. It seems to me that Peter is a … . He’s dressed in … . He may have a family … . He seems to be … . He must live … . He may like … .

2. What about you? What is your lifestyle like? Is there anything you would like to change? Tell your partner.

   e.g. I’m an only child and I live with my parents in the city centre. I go to secondary school. I like casual clothes and enjoy playing computer games. I guess I’m an easy-going person.

Listening

3. Read the definition.

   Nanotechnology = science of making and working with things that can only be seen using a powerful microscope.

   How do you think nanotechnology might affect people’s lifestyles? Listen and take notes under the headings below. Tell the class.

   • transportation
   • consumer products
   • environment
   • food
   • medicine

4. RNE Read the text and complete gaps A–F with the parts of the sentences marked by numbers 1–7. One part is extra. Then translate the first two paragraphs of the text into Russian.

   1. which prevents invasion by foreign bodies
   2. which would be an incredible development
   3. because it is a world that may not be far off
   4. which will improve their fuel efficiency
   5. which means an operation is necessary
   6. which they can use to track the spread of the disease
   7. that nanotechnology may be difficult to control

   Nanotechnology: the next big thing?

   Nanotechnology, the technology of materials of microscopic size, is seen as controversial by many. This article looks at some of the benefits—and potential dangers.

   Imagine a world in which kitchens clean themselves, tiny brushes clean up pollutants in water, and minute robots move through the body seeking out and destroying cancerous tissue. If this sounds like science-fiction, you should think again, A), because it is a world that may not be far off. In this new branch of technology these ideas are only some of the possible applications of scientific research. Scientists even hope to develop materials that will allow machines to repair themselves in much the same way that the human body does, B).

   Although the idea of using microscopic robots to fight disease is still futuristic, nanotechnology is already being used by doctors. For example, magnetic nanoparticles have been given to patients suffering from certain cancers. These tiny metal balls concentrate in the body’s unhealthy tissues, giving doctors a useful tool C) which they can use to track the spread of the disease.

   Unfortunately, it is not all good news. People are already expressing concerns D) that nanotechnology may be difficult to control. They fear the world could rapidly be reduced to grey dust as the result of some disaster involving this new technology.

   Nanoparticles are so small that they are readily taken up by the body. Normally, the skin acts as a natural barrier E) which prevents invasion by foreign bodies. However, nanoparticles are able to cross biological membranes and penetrate tissues and organs. Indeed, nanoparticles may cause DNA mutation and the destruction of cells.

   Nevertheless, nanomaterials can actively benefit the environment and help in the fight against global warming. They can also be used to improve the efficiency of traditional materials. For example, a nanoparticle is being added to engines in buses in Britain F) which will improve their fuel efficiency.

   To conclude, then, as with most advances in technology, the message must be: “Proceed with extreme caution.”

5. Complete the phrases with the words below. Use the completed phrases to make sentences based on the text.

   1. potential dangers
   2. cancerous tissue
   3. science fiction
   4. to fighting disease
   5. fuel efficiency
   6. foreign bodies
   7. global warming
   8. traditional materials
   9. environmental catastrophe
   10. extreme caution
   11. natural barrier
   12. biological membranes

6. Match the words in meanings: quickly, go, bold, to these, ahead, area, fix, worries, tiny, looking for, uses, help, change, debatable.

Listening & Speaking

7. Listen as you read the text again. Then tell your partner what the positive and negative effects of nanotechnology would be.

Writing

8. Think! Do you think nanotechnology will change people’s lives? Spend three minutes writing about the topic.
