- Read the text about microchips. How many different uses for microchips are described?
- Underline the best form, active or passive, so that it a) keeps the focus on the main ideas and b) is correct.
Resposta
a) Four
- in fridge → to remind you when it's time to buy something
- babies → to monitor a person all their lives
- criminals → to keep track of them
- attached to any object → to help you find it when you lose it
b)
- they can be placed (this keeps microchips as the main focus)
- you can be reminded (now the focus shifts to 'you' and what 'you' do, i.e. it's not focusing primarily on the microchips anymore)
- you to buy something (keep the focus on 'you')
- microchips could be implanted (keep the focus on microchips, the main topic of the whole text)
- Microchips could also be implanted (keep the focus on microchips)
- keep ('police is the subject or agent of the verb, so it needs an active verb)
- a crime is committed (we don't know who commits the crime)
- you can buy a set of clip-on microchips (the new focus is on 'you' established at the beginning of this sentence)
- both answers are possible, but 'can be attached' sounds better since the focus has just shifted to 'a set of clip-on microchips'
- both answers are possible; the first ('you can use your phone') sounds slightly less formal
