5 . In 2005, Winston Duncan was traveling with his mother in Southern Africa when he saw an old lady and young boy walking down a road together. He thought of his own grandmother and wondered how he could help the old lady and others in Africa who have to walk a long way.

Duncan, who lived in Washington State was 10 at the time, and his solution was to give them bikes. With his mom, he started Wheels to Africa, an organization that for the past 14 years has taken bicycles donated from residents of the. Washington area and shipped them across the world to people in need.

Most of the 8000 bikes they have collected have gone to countries in Africa, helping cut down hours of walking for students and other postmen. But last week, Duncan, travelled with a handful of volunteers and 400 bikes to a destination much closer to his home yet still in need: Puerto Rico. More than a year after it was destroyed by Hurricane Maria, the island suffers from transportation problems.

"It was a little chaotic (混乱的) — as soon as they got their bikes, they were just having fun riding around the parking lot," said Austin Higgins, a New Jersey resident who recently joined Wheels to Africa as its photographer and videographer. "Some people who received bicycles were almost speechless, and some of them cried, because it was something they had requested for Christmas from Santa Claus," he said.

The donated bikes included some high-end racing models, which went to teenagers interested in pursuing serious cycling.

Duncan recently graduated from Bard College and is in Arlington working at a political consulting firm. He now encourages kids in the Washington area to get involved with the organization, and some have joined him on trips to Africa and on this trip to Puerto Rico.

"I wanted to try to get people to think about giving back,” he said.

6 . The Worlds' Best Bookshops

There's nothing like being surrounded by books， wherever you are． Here are the finest oases of literature that travellers can bring you．

Daikanyama T﹣site | Tokyo

It is well worth visiting even if just to admire the building's beautiful， crisscrossed architecture． Once you've had your fill of roaming three floors' worth of bookshelves， there's the bar， the coffee shop， or even the video rental space to give you more reason to stay just that little bit longer． Grab a book， order a beer and dive into its pages． I could have stayed hours here．

City Lights | San Francisco

The three﹣storey establishment publishes and sells titles in poetry， fiction， translation， politics， history and the arts． It hosts events and readings， and runs a non﹣profit of the same name that aims to promote diversity of voices and ideas in literature． It's opposite Vesuvio， a bar frequented by Kerouac and other Beat﹣generation writers and artists．

Shakespeare and Company | Paris

I made a special trip to the Left Bank for this one when I was in Paris． It has two floors packed with English﹣language texts， and I was particularly struck by any spare wall space devoted to notes from visitors ﹣ heartfelt messages to a loved one， dedications to the shop itself， or a quote from a favourite author or philosopher．

Hutatma Chowk | Mumbai

A few years ago I visited India， investigating Rudyard Kipling's connections with the country． I spotted a cheap copy of The Jungle Book on one of the tarp﹣covered book stalls at Hutatma Chowk （Martyrs' Square）． The booksellers here are like amateur librarians， able to lay their hands on almost any title you ask for． To me， those well﹣thumbed （翻旧了的） books spoke volumes about the changes of Mumbai's readers in the 150 years since the city gave us Kipling．
