Sustainable tourism, which is becoming increasingly popular nowadays, is not just about seeing the sights — it is also about connecting with people and their cultures,     1     (make) a positive impact on the places we visit and enhancing opportunities for the future. So,     2     can we be sustainable tourists?

It is important to travel in     3     environmentally friendly manner. Getting to a tourist destination by airplane, which greatly     4     (increase) our carbon footprint, has a huge impact on the global environment. While avoiding flying is not always     5     (practice), we can help improve the environment by travelling on local public transport or even on foot wherever possible. When at the hotel, we can reduce our impact by cutting back on water consumption and not having our bedding and towels     6     (wash) every day. We also need to protect the local culture. When visiting temples or churches,     7     a strict dress code may     8     (require), we should dress appropriately. While travelling, we should respect the right to privacy. We must ask for     9     (permit) before taking pictures of the local people, who are human beings and not     10     display.

In summary, being a sustainable tourist comes down to respect — for nature, culture and people.

Wood acknowledges that his ________ was often dependent on the hospitality (好客) of local villagers. The people of the Sudan, he says, were probably the most ________ of all. Even sharing water, he says, ________ an incredible act of kindness.

“The biggest challenge was the sun ________ down. Most of the day I had to be ________ to the sun,” he recalls, “My guide had a catapult (弹弓). He would shoot pigeons. Other times we’d eat with villagers. The local ________ could vary, from grasshoppers to rats.”

The journey wasn’t without danger. Civil War in South Sudan ________ shortly after his arrival. He made it halfway through the country, to Bor—the front line of the war.

I’ve had my fair share of travelling around China, and a recent week-long trip to Guizhou was my first time to the province. I tried looking up the meaning and significance of the name Guizhou before the trip,     1     (basic)to have a reasonable idea of what was in store for me. But that was     2     hard task so I inquired from a Chinese colleague on the trip. From what she said, initially the province     3     (name)after a famous mountain called “Gui”, sort of noble in literal translation and “zhou”, which simply means province in Chinese.     4     (keep)that in mind I set out on a journey of discovery and     5     I found was mind-blowing, a photographer’s paradise. Generally     6     (describe)as a mountainous province in southwestern China, with Guiyang as     7     (it)capital, the province is truly one of nature’s best kept secrets. Compared to other leading     8     (province)in China, with regard     9     development, Guizhou has some catching-up to do. However, the province remains unique not only for its amazing landscape,     10     for the role it played in the political history of modern China and the role it is to play in the world.
