Track 35

Every day we throw away objects such as wood, old household appliances, and glass bottles. But an artist from Uruguay called Jaime built a house made from these types of objects. The house is in Brazil and it has a bedroom, a kitchen, and a bathroom. There are shelves made from trees and old wood and there’s lots of light. That’s because Jaime used coloured glass from bottles in the walls. When people visit the house, Jaime wants them to think about the environment and about how we recycle and reuse everyday objects.

3 Look at the highlighted expressions for talking about objects. Make similar sentences about the everyday objects in the box. A dictionary is made of paper. You use it for looking up words. EXAMPLE ANSWERS A mobile phone is made of metal and plastic. You use it for phoning people, for sending text messages, for searching the internet, etc. A pen is made of plastic and metal. You use it for writing. Scissors are made of metal. You use them for cutting things. A tin can is made of metal. You use it for keeping food.

4 Work in pairs. Think of other everyday objects. Don’t tell your partner the object, but describe what it’s made of and what you use it for. Your partner has to guess the object.

EXAMPLE ANSWERS A tablet is made of metal, glass and plastic. You use it for going online. A box is made of cardboard. You use it for holding, storing or carrying things. A knife is made of metal. You use it for cutting things. Unit 5-p. 57

Reading 3 Look at the photos with the article. What do you think e-rubbish is? Why is the boy holding part of an old computer? Students’ own answers. The actual answers are in the article and in the answer key in the next exercise.

4 Read the article and check your ideas from Exercise 3. E-rubbish (electronic rubbish) refers to the many computers, TVs, laptops and phones we regularly throw away.

The article says that people melt parts of the computers to recycle the metal. The boy is probably collecting parts of the computers that have valuable metal in them. 5a-p. 58

Track 36

Do you ever throw away any electronic rubbish (or e-rubbish)? Perhaps you have some old technology that doesn’t work, like an out-of-date phone, or a slow computer. But when you throw away these objects, do you know where they go? The journalist Peter Essick has followed this e-rubbish to different countries around the world. Essick found a lot of e-rubbish in Ghana, with thousands of old computers in the local markets. Here, the sellers resell a few computers to people for their homes and offices, but you can’t sell many computers in the market because a lot of them don’t work. So they melt some parts of the computers to recycle the metal. These parts don’t have much metal, but sometimes there is a little gold inside. Unfortunately, recycling the metal can be dangerous for the workers because it produces a lot of chemicals which are bad for workers’ health. As a result, Peter Essick thinks we shouldn’t send any e-rubbish to other countries. It’s bad for the environment and it’s bad for people’s health. He believes we need to produce more environmentally-friendly electronics in the future; in other words, electronic products which you can recycle safely and in the country where they were made.
