Pre-reading
1. What are the differences between Leo’s two trips
1) In 2008, Leo took a taxi to the hostel from the airport and it cost him a fortune! In 2018, the trip from the airport to the city centre was much cheaper because it was a shared ride.
2) In 2008, Leo stayed in a hostel, while in 2018 he stayed in a shared flat.
3) In 2008, Leo didn’t know how to get to Houhai, while in 2018 he had a nice trip around Houhai by riding a shared bicycle.
4) In 2008, Leo could only have a pizza in the hostel alone and he didn’t know where to have good Chinese food. In 2018 he shared a delicious meal of Chinese cuisine with some other backpackers at Chef Cui’s restaurant.
5) In 2008, Leo had a battery problem with his camera. He didn’t have this problem in 2018, because he could use the shared power banks.
2. Which one do you think was more fun Give your reasons.
One possible answer: I think the second one is more fun. During his second trip, Leo had a more wonderful experience by sharing so many things. He tasted delicious Chinese food, enjoyed a beautiful view but spent less money. That was brilliant!

b. To explain and elaborate on the sharing economy.
Para. 2. Sharing has expanded to almost every aspect of people’s lives. People are using technology to reduce the money that they spend on goods and services, or to make money out of those that they don’t use themselves all of the time. The sharing economy is taking off in all sorts of areas.
c. To lead the topic from sharing in childhood to sharing in economic activities.
Para. 1. By saying that we have been told since we were toddlers that “It’s good to share”, the author starts paragraph one and leads into the topic on sharing gradually.
d. To illustrate various drawbacks of the sharing economy.
