In 2014, I was looking through a Facebook group when I spotted a post claiming $200 roundtrip tickets to Dubai, With little     1     (hesitate), I confirmed the deal, checked my calendar and     2     (book) tickets. No asking friends, no waiting     3     job approvals, and no overthinking. It would be my first trip alone.

I met Jibri during the layover. She got my attention and we started chatting about travel deals and groups. During our small talk, I considered     4     (put) my earphones back in or making up a reason to excuse     5     (I). However, I finally decided to continue interacting with the new person and see     6     it could lead, In fact, she left a deep impression on me. Not only     7     we exchange contact information to meet in Dubai, but we joined other travel group members who rented a boat for an afternoon trip.

It was totally outside of my comfort zone! Unexpectedly, I met amazing people and gained     8     (wonder) friendships. I learned     9     (trust) my abilities and instincts(直觉) even when I had to improvise(即兴做事). I learned that strangers were just friends who hadn’t met you. Most importantly, I learned that my suitcase was much     10     (light) when I didn’t fill it with fear.

With the days    1    ( grow) colder, Pasang has made preparations for the winter by purchasing    2    generous amount of natural gas to warm his home.

“In the past, we burned cattle dung (牛粪) for heating. The rooms would be covered with dust, and the sky would sometimes get gray,” said Pasang, a resident of Lhasa, capital of southwest China’s Tibet Autonomous Region.

His home was connected by natural gas pipelines seven years ago. “With the gas, my home is warmer, and we are also contributing    3    bluer skies,” he said.

Now, the signature blue skies dotted with white clouds not only give local people a breath of fresh air but are also a vital part of the region’s charm for visitors from home and abroad. The wide use of natural gas is one of the keys behind the clean air in Tibet. “In Lhasa’s case, so far natural gas    4    (adopt) for heating in more than 90 percent of its urban area,” said a local company in charge of natural gas supplies.

Amid the country’s boom of new energy vehicles (NEVs),Tibet is also popularizing NEVs while phasing out (淘汰) older cars with high pollution and high energy    5    (consume).

Electric cars are also gaining    6    (popular) for their eco-friendly features and lower costs. Penpa, another resident in Lhasa, said he and many of his friends have replaced their traditional vehicles with electric ones. “Everyone should make an effort    7    (keep) the air clear in Lhasa,” Penpa said.

Atop a mountain over 5,000 meters above sea level, the Ali observatory — more than 1,400 km from Lhasa — is still frequented by astronomy lovers    8    brave (勇敢面对) a zigzagging road to get a much    9    (close) look at the stars.

Zhou Yunhe, director of the observatory, said more than 3,100 tourists have visited the observatory since the turn of the year.

Despite the impact of COVID-19, Tibet received 36.89 million tourists in the first three    10    (quarter) this year, up 15.2 percent year on year, and tourism revenue surged 26.6 percent, official data showed.

Well, here we are in Cairo at last. This morning, we explored an old market area. It was very atmospheric and filled with lots of interesting things. I    1    (buy) a beautiful necklace for you. Mum—it looks just like one    2    Queen Cleopatra would have worn! Anyway, we’re going out to eat some more of Egypt’s national dish now.

Huangguoshu Waterfall, also called Huangguoshu or Huangguoshu Falls, is the largest waterfall in Asia and the third largest waterfall in the world.     1     (undoubted), it is Guizhou's NO.1 natural attraction. Compared     2     the amazing natural wonders — Jiuzhaigou National Forest Park in Sichuan and Zhangjiajie National Forest Park in Hunan, though Huangguoshu Waterfall is less visited by international travelers, it has     3     (it) own unique features.

Located on the Baishui River in Anshun, Guizhou (about 128 kilometers away from Guiyang,     4     capital of Guizhou), Huangguoshu National Park is centered at Huangguoshu Waterfall which is at 83 meters in width and 67 meters in     5     (high).

All the waterfalls form a great “family”,     7     is ranked as the largest waterfall cluster (群) in the world in the Guinness Book of World Records. Huangguoshu Waterfall is so impressive and it can     8     (view) from all angles — above, below, front, back, left and right.     9     (get) the best views and hear the deafening roar (轰鸣), travelers should visit Wang Shui Ting and the viewing platform by Rhinoceros Pool. It is a great idea to spend one day     10     (explore)Huangguoshu Waterfall from Guiyang City.

    1     ( sit ) back in my seat, I can’t believe that I’m about to travel along the railway that many foreign experts claimed was “impossible”. The train has been racing along     2     ( steady ) since it left Xining.

I was one of the people     3     came from all parts of China to work on this railway. Taking years to complete the Qinghai - Tibet Railway is a record of all of our efforts to overcome     4     most difficult challenges. How     5     ( protect ) the ecosystem was among the top concerns . The first landmark     6     ( catch ) my eye is the Qingshuihe Bridge, the world’s longest bridge built over permafrost. To prevent damage to wetlands and grasslands, 675 bridges     7     ( build ) between Golmud and Lhasa.

Tanggula Station,     8     ( locate ) at over 5,000 metres above sea level, is the highest railway station in the world. To make sure we stayed healthy, several oxygen - making stations were constructed. Passing Cuona Lake, I feel a sense of pride and     9     ( achieve ). Along the lake we built a twenty - kilometre wall to protect the lake     10     construction waste.

I’m proud that we built our “impossible” railway. It truly is an extraordinary “Sky Railway”.

For many people, bookstores remain an important part of the cityscape. They help provide quiet, green escape from the pressures of the concrete jungle, calm     1     （enjoy）of   knowledge and soothing spots for self-reflection     2    （recharge）the mind and body.

But     3     is it like to have a contemporary bookstore in an ancient village, deep in the mountains? A recent assignment to Chenjiapu village in Songyang county of Lishui city, East China's Zhejiang province,     4    （point）to the answer-the Librairie Avant-Garde, or“cliffside bookstore".

Ocean Park Hong Kong is one of Hong Kong’s greatest tourist     1     (attract). Because the park isn’t run for profit, it is much more suitable for education and wildlife conservation research. And     2     (compare) with other theme parks, it takes better care of the animals. In addition, you will find prices there fairly reasonable considering the size and the quality. Therefore, since its opening, the park     3     (draw) a large number of visitors.

And you can add money as you wish and have     9     returned to a station window for the remaining money back.

Wish you an     10     (enjoy) day in Hong Kong’s most popular theme park.

During the October holiday, my parents and I made a trip to Mount Wuyi,    1    is lying at the junction (交叉点) of Fujian and Jiangxi Provinces. It is a popular tourist attraction. In December 1999, Mount Wuyi is listed as the World's natural and    2     (culture) heritage by the UNESCO.
