Exercise 1 (Track 3.27)
• Individually, students match the words and the pictures.
• Make sure students understand that they should match the first set of pictures to the verbs and the second set to the nouns.
• Play the recording for students to listen and check.
• Repeat the recording. Pause after each word to check students’ pronunciation.
Answers
Stronger groups or individual students write simple instructions for another machine they use regularly, e.g. a computer, a microwave, a mobile phone, a digital camera , using the text in Exercise 2 as a model and including vocabulary from Exercise 1 where appropriate.
Monitor and help with vocabulary and grammar and feed in ideas if necessary. When checking students’ work, focus on the positive use of the grammar and vocabulary taught so far.
• Read through the example with students and ask what is being described (Answer: a torch).
• Students work in pairs, taking turns to describe the objects in the box.
• Monitor and help with vocabulary, but do not interrupt fluency.
• Ask some students to say their descriptions for the class to hear.
Possible answers
laptop – It’s got a battery, but you can also plug it in to use it. It’s got a keyboard and a screen. You can use it to work, play games, use the internet and communicate.
memory stick – This is very small and doesn’t have any buttons. You can attach it to a socket on your computer to copy and move information.
mobile phone – You have to plug it in every day because it uses the battery quickly. You need to switch it on before you use it and use the keyboard to send messages or make calls.
train – This invention has wheels and is very expensive to produce. We use them for transport over long and short distances. Some of them are very fast and some are slower.
TV – You have to plug this in and switch it on to use it.
It has a screen and usually has some buttons. It has a remote control to change channel.

• Make sure students understand not to read in detail at this point.
• Students scan the magazine article quickly to match the paragraphs to the photos.

1 b 2 c 3 a Exercise 3 (Track 3.28)
• Individually, students decide if the sentences are true or false.
• If you wish, play the recording for students to listen and read.
• When checking answers, ask students to read the section of the text(s) which supports their answers.
Answers
1 False (‘He became blind in an accident when he was only three years old.’)
2 False (‘At the age of twelve, he learned about a system of writing with bumps in paper that you feel with your fingers.’)
3 True
4 False (‘Messages that are sent on …mobile phones can’t travel through rock.’)
5 True
6 False (‘Hibiki isn’t allowed to use the gloves in his bedroom.’)
Extra activity
Students write a short paragraph about another inventor.
They can choose either a famous inventor or someone who has made a more unusual invention.
When checking students’ work, focus on the positive use of grammar and vocabulary taught so far.
Use some of the students’ written work as the basis for further comprehension practice. Select three of the most interesting and varied texts and prepare two comprehension questions or true/false statements about each. Students then read their classmates’ texts and answer the questions.
Exercise 4
• Read through the examples with students.
• In pairs, students ask and answer the questions.
• Monitor and help with vocabulary, but do not interrupt fluency.

Cultural notes
• Louis Braille completed his system of raised writing in 1824 when he was only 15. He simplified a much more complicated system, which had been used by the French army to allow soldiers to send messages and communicate silently. Interestingly, the tool he originally used to create the patterns of raised dots on the paper was the same tool which had blinded him in an accident when he was three. His system has since been adapted for all major world languages and for music, and there are now even Braille computers and Braille email services.
• Alexander Kendrick is from Los Alomos in New Mexico. He won the 2009 International Science Fair Prize at the age of 16 for his invention, receiving a new computer, a visit to Switzerland and $12,000 as a prize. His ‘cave phone’ consists of two large, lightweight transmitters, one of which the caver leaves outside the cave and the other which is assembled underground. These transmitters use low-frequency radio waves to send written text messages from the caver deep below ground to people on the surface.
• Hibiki Kono studies at King’s College School in Cambridge and in 2010 his unusual invention was widely reported in the media, earning him the nickname ‘Spiderboy’. He made it as part of a school technology project. The invention uses two vacuum cleaners, bought from the local supermarket for a total of £30, and these are attached to special gloves which use the suction to stick to the wall. To climb, Hibiki turns off one vacuum cleaner, allowing him to move that hand up the wall, before turning it back on and turning off the other.
Exercise 1
• Draw attention to the photos and ask students what they can see.
• Individually, students think of famous inventors and their inventions.
• Take feedback as a class.

1 Think of some famous inventors. What did they invent?
2 Read the magazine article quickly. Match the paragraphs (1–3) to the photos (a–c).
3 3.28 Read the article again. Are these sentences true (T) or false (F)?
1 Louis Braille could never see. F
2 His system of writing was a completely new idea.
3 Alexander Kendrick’s invention can help people with injuries.
4 People should always have a mobile phone with them when they are caving.
5 Hibiki Kono’s invention uses machines that many people have in their homes.
6 He uses his invention to climb the walls in his bedroom.
4 What do you think?
1 Which of the inventions in the photos is:
a the cleverest?
b the most useful?
c the most fun?
Say why.
I think the low-frequency radio is the cleverest invention. It’s very difficult to build a radio and this radio can do things that other radios can’t do.
I would invent a robot that could do all my homework
for me!
2 If you were an inventor, what would you invent?
You don’t have to be old with crazy white hair to invent something. Here are some of our favourite young inventors.
1 Louis Braille (1809–1852) was French. He became blind in an accident when he was only three years old. At the age of twelve, he learned about a system of writing with bumps in paper that you feel with your fi ngers. Louis liked this idea, but the writing was diffi cult to read. For the next three years, he worked on a similar but easier system.
The result of his work was
‘Braille’ writing. The fi rst book in Braille appeared in 1829 and Braille is still used by blind people today.
2 Sixteen-year-old Alexander Kendrick loves caving, but it’s a very dangerous activity.
When accidents happen underground, it’s impossible
to communicate with the outside world. Messages that are sent on traditional radios or mobile phones can’t travel through rock. Alexander has built a special low-frequency radio that works 300 metres underground. It is made with plastic tubes and metal cable and messages are written on a keyboard. This clever machine might save a lot of lives in the future.
3 Gloves aren’t usually used to climb walls, are they?
Well, thirteen-year-old Hibiki Kono has invented special gloves! A small vacuum cleaner is attached to each glove. When the vacuum cleaners are switched on, the gloves can carry the weight of a large person on a wall or ceiling. But Hibiki isn’t allowed to use the gloves in his bedroom. His mum thinks they’re too dangerous.
