UNIT 9. TRAVELLING IN THE FUTUREReading

Read the conversation and choose the best answer.

Mai: … That was about future air travelling. Now we'll talk about future road transport with slidewalks, skycycling, and bicycles.

Veronica: Slidewalks are similar to moving walkways in airports. When slidewalks replace our pavements they'll help us move faster.

Phuc: Skycycling tubes hang from monorails and you can cycle while watching the city from above.

Veronica: Intelligent bikes have foldable roof for rainy weather. They'll never be stolen because they use fingerprint lock.

Mai: All of them are environmentally friendly. Slidewalks use electricity, while skycycling and intelligent bikes use human power. But in our opinion intelligent bikes will be the most common, because building slidewalks and skycycling system can be expensive.
