4 . It might be _______ to choose what everyone has done, especially if it seemed to work for them. But is that what truly _______ for you?

On a recent hiking _______, my partner and I decided to take a popular trail in the _______direction. This was an old, well-traveled trail that people had been hiking and biking from A to Z for years. For our own reasons, we chose to travel from Z to A. Going backwards made more sense with my _______. The trip would take several days and going backwards _______ that I would end the trip closer to the airport for my flight home.

As my partner and I walked, everyone crossing our path had something to say, “You're going the wrong way. Are you lost? Are you returning _______ you forgot something? Are you crazy? The path occasionally crossed a _______. When it did, even passing cars beeped to _______ us in the “right” direction.

Why did people only see one way? Because that's what everyone does? Because that's how it's always been done? We even ____________ to talk to a Danish woman who said, “We have a(n) ____________ in my country: when you go backwards to everyone else, it's because you're avoiding something.” I couldn't believe it. We were just enjoying connecting with nature, hiking the way that best ____________ us. Had we gone the “wrong” way? No. At least, not for us.

I decided to ____________ the path I chose. ____________, we had an amazing experience. Choosing the “wrong” path was right for me. When your inner ____________ tells you something is right (or wrong), listen to it. It's your instinct. It's speaking to you for a reason and it knows, better than anyone, what's best for you.

5 . Stories about the problems of tourism have been numerous in the last few years. Yet it does not have to be a problem. Although tourism inevitably affects the region in which it takes place, the costs to these fragile (脆弱的) environments and their local cultures can be ______. Indeed, as has happened with some Alpine villages，it can even be a(n) ______ for refreshing local cultures. And a growing number of adventure tourism ______ are trying to ensure that their activities benefit the local population and environment over the long term.

In the Swiss Alps, communities have decided that their future depends on combining tourism more effectively with the local ______. Local concern about the rising number of second home developments in the Swiss Pays-d’Enhaut resulted in ______ being imposed on their growth. There has also been a new interest in cheese production in the area, providing the locals with a ______ source of income that does not depend on outside visitors.

Many of the Arctic tourist destinations have been exploited by ______ companies, who employ temporary workers and send most of the profits back to their home base. But some Arctic communities are now operating tour businesses themselves, thereby ensuring that the benefits increase ______. For instance, a native corporation in Alaska, employing local people, is running an air tour from Anchorage to Kotzebue, where tourists eat Arctic food, walk on the lands and watch local musicians and dancers.

Native people in the desert regions of the American Southwest have followed ______ strategies, encouraging tourists to visit their towns and reservations to ______ high-quality handicrafts and artwork. Some have established highly profitable stoneware businesses, while the Navajo and Hopi groups have been similarly ______ with jewelry.

Too many people living in fragile environments have lost control over their economies, their culture and their environment when tourism has spread through their homelands. Merely restricting tourism cannot be the ______ to the imbalance because people’s desire to see new places will not just disappear. ______, communities in fragile environments must achieve greater control over tourism ventures in their regions, in order to ______ their needs and desires with the demands of tourism. A growing number of communities are ______ that, with firm combined decision-making, this is possible. The critical question now is whether this can become the normal status, rather than the exception.

8 . The view from the top of Marina Bay Sands, a giant hotel, mall and casino, takes in the skyscrapers of Singapore, the fleets of ships entering and leaving the city's ports, the scattered tropical islands of the Singapore Strait and the crowds of soggy but determined selfie- takers trying to capture a perfect image of it all from the enormous infinity pool. Among the celebrities the hotel has lured (吸引) for a damp snap are Jing Boran and Fu Xinbo, Chinese film and music stars. China Daily, a Chinese state-owned newspaper, has declared the spot the eighth most romantic in the world. The place displays itself all over Chinese social media and offers special discounts and packages to visitors from China.

Such spin is increasingly important. Last year, for the first time, China was the biggest source of tourists to Singapore, accounting for 3. 2m of its 17. 4m visitors. Between January and September alone they spent more than $3bn ($ 2.3bn).

All across South-East Asia， tourism is booming. The number of visitors jumped by 49% between 2010 and 2015， to more than 109m. Tourism in Asia and the Pacific is growing faster than anywhere else in the world. The region receives a quarter of the world's holidaymakers (Europe’s share is still a half).

South-East Asia’s Edenic islands, ancient temples and delicious food are strong enticements (诱惑，怂恿). Visitors also flock to countries with cheap currencies: the weakness of the ringgit last year helped draw visitors to Malaysia, for example. Many countries in the region depend on the cash: tourism accounts for about 28% of Cambodia’s GDP and more than 20% of Thailand’s.

The most remarkable growth has been in tourists from China. The number visiting South-East Asia has increased fivefold over the past decade. Newly wealthy Chinese spent almost $ 26lbn travelling abroad in 2016, up from $73bn in 2011.

Indonesia, for one, has relaxed its visa rules to attract more of them. More seats on cheap flights have also helped pull in tourists: between 2013 and 2016 the number available each week on flights to South East Asia from China increased from 92,000 to 188,500.

But for the frenzied holidaying to continue to grow, infrastructure must improve, reckons Paul Yong of DBS, a Singaporean bank. Airports in places such as Manila and Jakarta are crumbling and surrounded by snaking traffic. Plans are afoot to increase annual capacity at Bangkok’s airports by tens of millions over the next four years. Hanoi’s Noi Bai will be expanded at a cost of $5.5bn to accommodate 35m passengers by 2020. Airports in Singapore and Kuala Lumpur are to be upgraded too.

Other threats to thriving tourism are far harder to plan around, Travel operators tremble at the thought of economic downturns, volcanic eruptions and epidemic diseases. The head of one luxury holiday company says the regional outbreak of SARS, a respiratory disease, more than 15 years ago almost brought the industry to its knees. Political spats between China and its neighbours are another problem. So too is the manner in which Chinese visitors have been vilified in the region for snaffling prawns at buffets, barging into queues and misbehaving on planes. It makes many of them feel unwanted. But given that just 135m of China's 1. 4bn people have ever travelled abroad, South East Asian countries should prepare to welcome many more Chinese — even when they clog up the infinity pool.

Many people dream of traveling to faraway places and sailing the seven oceans on a luxurious ship. But     1    if you could combine a relaxing trip through the Caribbean with doing something good for the local communities of the places that you visit? Cruise ship(游轮) company Carnival has taken that thought to the next level and six months ago Fathom came into use.

This creative cruising offers passengers a chance     2    (spend) a day volunteering instead of sunbathing or swimming in the sea. They can participate     3    voluntary activities during their stay on the shore. Since Fathom first     4    (start) visiting the Dominican Republic in late April,     5    (it) passengers have fixed 730 water filters(滤波器),     6    (build) 40 concrete floors, planted almost 16 000 seedlings, and provided about 17 500 hours of training to help locals practice spoken English.

Demand for social impact cruises is on the rise. Starting in November 2016, six other companies offer similar trips to the Dominican Republic. Fathom will soon also offer trips to Cuba,     7    motivated passengers can choose from two different voyages and a     8    (vary) of voluntary activities. The trips are all about     9    (culture) exchanges and discovering the beauty of places that tourists might usually not reach. Their warm reception clearly shows that more people want to get     10    (involve) in having a positive impact and help those less fortunate than them.
